What should your units on your base area calculations be, and why? How is this different from the units on your volume calculations

Answers

Answer 1

The units for base area calculations are squared units and the units for volume calculations are cubed units. This is because the area and volume calculations require different equations and different units of measurement.

The units on your base area calculations should be squared units, such as square meters, square centimeters, square inches, or square feet. This is because the area of a two dimensional shape is the amount of space occupied by the shape and is calculated by taking the length of the base and multiplying it by the width of the base. For example, if a rectangle has a length of 5 meters and a width of 3 meters, the area of the rectangle would be 5 x 3 = 15 square meters.

The units on your volume calculations should be cubed units, such as cubic meters, cubic centimeters, cubic inches, or cubic feet. This is because the volume of a three dimensional shape is the amount of space occupied by the shape and is calculated by taking the area of the base and multiplying it by the height of the shape. For example, if a cube has an area of 15 square meters and a height of 4 meters, the volume of the cube would be 15 x 4 = 60 cubic meters.

Boubacar has a loyalty card good for a 11% discount at his local grocery store. If the total cost, before tax and discount, of all the items he wants to buy is c, which expression represents the cost after the discount?

Answers

The expression that represents the cost after the 11% discount is 0.89c. This means that Boubacar will pay 89% of the original cost after the discount has been applied.

How to calculate discount?

To calculate the discount, you need to determine the discount rate, which is usually a percentage of the original price. Multiply the discount rate by the original price to find the amount of the discount.

Finally, subtract the discount amount from the original price to get the discounted price.

The discount that Boubacar gets on his purchase is 11% of the total cost before tax and discount. To calculate the discount, we multiply the total cost (c) by 11% or 0.11, which gives us:

Discount = 0.11c

To find the cost after the discount, we subtract the discount from the total cost. This gives us:

Cost after discount = c - Discount

Cost after discount = c - 0.11c

Cost after discount = 0.89c

Your room has 300 square feet of wall space to paint. Sam says it took her 10 minutes to paint 25 square feet. At this rate, how many hours would it take Sam to paint your room?

Answers

Answer: 2 hours

Step-by-step explanation: (10 min) / (25 square feet)   =  (X minutes) / (300 square feet)

Cross-multiply to solve, as we always do with proportions:

10 * 300  = 25 * x

3000       = 25X

3000/25  = 25X /25

    120     = X

120 minutes * (1 hour / 60 minutes) = 2 hours

Answers

The value of  tan(A - B)  will be 15/8.

As mentioned,  cscA= -17/15 and A is in Quadrant III and sinB=12/13 where B is in Quadrant I To find tan(A - B), we need to have the values of sin (A - B) and cos (A - B).We know that, sin(A - B) = sinAcosB - cosAsinB and cos(A - B) = cosAcosB + sinAsinB.Since we have the values of sinA, cosA, and sinB, let's find the values of cosA and cosB.First, let's find cosA. We know that cscA = 1/sinA. Therefore, sinA = -15/17.Since A is in Quadrant III, sinA < 0, cosA < 0, and tanA > 0.

By using the Pythagorean identity sin^2A + cos^2A = 1, we get cosA = -8/17.Next, let's find cosB. We know that sin^2B + cos^2B = 1.

Therefore, cosB = sqrt(1 - sin^2B) = 5/13.

Since B is in Quadrant I, sinB > 0, cosB > 0, and tanB > 0.

Now, we have sinA, cosA, sinB, and cosB.

Using the values of sinA, cosA, sinB, and cosB, let's find sin(A - B) and cos(A - B).

sin(A - B) = sinAcosB - cosAsinB= (-15/17)(12/13) - (-8/17)(5/13)= -180/221

cos(A - B) = cosAcosB + sinAsinB= (-8/17)(12/13) + (-15/17)(5/13)= -96/221

Finally, tan(A - B) = sin(A - B) / cos(A - B)= (-180/221) / (-96/221)= 15/8. Therefore, tan(A - B) = 15/8.

Answers

About 16 people among the 1,000 insured people can file a claim for a surgical procedure.

define profit

Profit is the financial gain earned by a business or an individual after deducting all the expenses and costs associated with generating that revenue. It represents the difference between the total revenue earned and the total expenses incurred.

The total amount collected in premiums over 3 years for Bracken is:

$100 x 1,000 x 3 = $300,000

Assuming x people among the 1,000 insured people file a claim for a surgical procedure, the total amount paid out in claims by Bracken would be:

$25,000 x x = $25,000x

The total deductible paid by the claimants would be:

$3,500 x x = $3,500x

So, the total amount paid out by Bracken would be:

$25,000x + $3,500x = $28,500x

For Bracken to break even, the total amount collected in premiums should be equal to the total amount paid out in claims plus the deductible for 3 years.

$300,000 = $28,500x + $3,500(1,000 - x)

Simplifying and solving for x, we get:

x = 16

Therefore, about 16 people among the 1,000 insured people can file a claim for a surgical procedure for Bracken to break even over the passage of 3 years.

A trapezoid has a base of 5 millimeters,
another base of 7 millimeters, and a height
of 6 millimeters. Explain how the area of the
trapezoid will change if the height and both
bases are doubled.

Answers

The area will rise by a factor of four if we double the base and height of a trapezoid.

Explain about the trapezoid?

A quadrilateral with a single set of parallel sides is referred to as a trapezoid. The parallel and non-parallel sides are referred to as bases and legs, respectively. The distance between the bases of a trapezoid measured perpendicularly is its height.

The formula for a trapezoid's area is:

Area is equal to (base1+base2)*height / 2.

Considering that the height is 6 millimeters, the first base is 5 millimeters, and the secondary base is 7 millimeters, we may determine the trapezoid's initial area as follows:

Area = 1/2 *(5 + 7)* 6 = 36 sq. mm

Doubling the height and both bases:

New base 1 = 2 * 5 = 10 mm

New base 2 = 2 * 7 = 14 mm

New height = 2 * 6 = 12 mm

The new area of such trapezoid can be calculated using the same formula:

New Area = 1/2* (10 + 14) * 12 = 144 sq. mm

When we compare the new area to the old area, we are able to see that the new area has been four times bigger.

So, if the base and height of just a trapezoid are both doubled, the area will grow by a factor four.

The city underpass renovation can be finished by 34 men in 40 days. If 9 of them withdraw before the work started, how many days are they going to finish the work?

Answers

It will take 55 days to finish the renovation with 25 men.

If 34 men can finish the renovation in 40 days, we can say that the number of men is inversely proportional to the number of days needed to finish the work. Therefore, we can write:

Number of men × Number of days = Constant

We can find the value of the constant by using the given information:

34 men × 40 days = 1360

This means that the constant is equal to 1360.

If 9 men withdraw before the work started, then the number of men who will work on the renovation is 34 - 9 = 25.

We can now use the constant to find the number of days needed to finish the renovation with 25 men:

25 men × Number of days = 1360

Number of days = 1360 ÷ 25

Answers

The polynomial f(x) = (5 − x)(x + 4)(7x + 3)2 has a degree of 2, a leading coefficient of 49, and a constant coefficient of 60.

The polynomial f(x) = (5 − x)(x + 4)(7x + 3)2 has the following degree, leading coefficient, and constant coefficient:

Degree: The degree of a polynomial is the maximum degree of any term in it.

Here, the term of highest degree is (7x + 3)2 which has a degree of 2.

Therefore, the degree of the polynomial is 2. Leading coefficient: The leading coefficient of a polynomial is the coefficient of the term of highest degree.

Here, the term of highest degree is (7x + 3)2 and it has a coefficient of 49.

Therefore, the leading coefficient of the polynomial is 49. Constant coefficient: The constant coefficient of a polynomial is the coefficient of the term of degree 0.

Here, there is only one such term, which is the constant term 60 (obtained by multiplying the constant terms of each factor: 5 × 4 × 9).

Therefore, the constant coefficient of the polynomial is 60.

Two​ joggers, one averaging 8 mph and one averaging 4 ​mph, start from a designated initial point. The slower jogger arrives at the end of the run 35 minutes after the other jogger. Find the distance of the run

Answers

The distance of the run is about 7.33 miles.

Let's anticipate that the distance of the run is "d" miles.

We realize that time = distance ÷ velocity.

For the first jogger who averages 8 mph, the time taken to finish the run may be represented as:

t = d ÷ 8

For the second jogger who averages 4 mph, the time taken to complete the same run may be represented as:

t + 35/60 = d ÷ 4

We can simplify this equation by substituting the value of "t" from the first equation:

d ÷ 8 + 35/60 = d ÷ 4

.

Multiplying each aspects through 24 (LCM of 8 and 4), we get:

3D + 7 = 6d

Simplifying this, we get:

d = 7.33 miles (rounded to two decimal locations)

What whole number is nearest to each square root? √22​

Answers

Step-by-step explanation:

The square root of 22 is an irrational number, which means it cannot be expressed exactly as a finite decimal or a fraction. However, we can approximate it by finding the whole number that is closest to it.

To do this, we can use a calculator or estimation. For example, we can guess that the square root of 22 is between 4 and 5, since 4 squared is 16 and 5 squared is 25. Then we can try averaging these two numbers:

(4 + 5) / 2 = 4.5

This means that 4.5 is an approximate value of the square root of 22. The nearest whole number to 4.5 is 5, so we can say that the whole number nearest to the square root of 22 is 5.

Describe volume.

The volume of a three-dimensional item, which is measured in cubic units, describes how much room it occupies. Cubic measurements are denoted by the characters cm3 and in3. To determine an item's size, you could use its bulk, though. The object's weight is typically transformed into mass units like grammes and kilos.

where the volume is V, the radius is r, and the height is h.

Inputting the numbers provided yields:

=> 1 1/16 = π(1/4)^2h

Simplifying:

Adding 16/ to both sides:

=> h = (16/π) x 1.0625

=> h = 16.8125/π

Answers

The actual outcome of his investment could still be positive or negative, depending on the actual performance of the individual stock.

Since each stock has a 50% chance of being successful and a 50% chance of failing, the expected value of each stock is:

(0.5 * 500) + (0.5 * (-500)) = 0

That is, the expected value of each stock is zero, because the potential gain of $500 is balanced by the potential loss of $500.

Now, since the stocks are independent, the expected value of Ajay's entire investment is simply the sum of the expected values of each individual stock:

Expected value of Ajay's investment = 222 * 0 = 0

So the expected value of Ajay's investment is also zero dollars. This means that, on average, Ajay should not expect to make a profit or a loss from his investment in these 222 stocks. However, the actual outcome of his investment could still be positive or negative, depending on the actual performance of the individual stocks.

A triangular bandana has an area of 86 square inches. The height of the triangle is 5 3/8 inches. An equation to find the length of the base of the triangle is 86 = 1/2 * b * 43/8

The length of the triangle's base is 32 inches.

We know that the formula for calculating the area of a triangle is:

1/2 * base * height = area

We also know that the triangle's height is 5 3/8 inches, which may be expressed as a mixed number:

Height = 5 + 3/8 inch = 43/8 inch

Let b be the base of the triangle.

Substituting these numbers into the area formula yields:

86 = 1/2 * b * 43/8

To find b, multiply both sides of the equation by 2/43:

86 * 2/43 = 2/43 * 1/2 * b * 43/8

4 = b/8

b = 32

As a result, the length of the triangle's base is 32 inches.

The multiplicative rate of change of a function is calculated by taking the ratio of the change in the output to the change in the input, which in this case would be 2.

The multiplicative rate of change of a function is the rate at which the output of the function changes in relation to the input. It is calculated by taking the ratio of the change in the output to the change in the input. The formula for this is:

Multiplicative Rate of Change = (Change in Output)/(Change in Input)

For example, if a function f(x) has an input of 3 and an output of 9, then the multiplicative rate of change of the function would be 2. This can be calculated by taking the difference between the output and the input, which is 9 - 3 = 6, and dividing it by the difference between the input and the output, which is 3 - 0 = 3. Thus, the multiplicative rate of change of the function is 6/3 = 2.

1 point) Solve the equation x²−4x−21=0 byfactoring.The solutions are x1=and x2=with x1

Answers

The solutions of x1 = 7 and x2 = -3 with x1 through solving the quadratic  equation x²−4x−21=0 by factoring

The equation :x² - 4x - 21 = 0, solve it by factoring it.The first step is to find two numbers that will multiply to give us -21 and add up to -4. These numbers are -7 and 3.So, we rewrite the equation using -7 and 3 instead of  -4x:x² - 7x + 3x - 21 = 0.

Group the first two terms and the last two terms: x(x - 7) + 3(x - 7) = 0.

Factor out the common factor of (x - 7): (x - 7)(x + 3) = 0.

Now, we have two factors that when multiplied, give us zero. This means that either (x - 7) = 0 or (x + 3) = 0.

Solving for x, we get: x = 7 or x = -3.

The solutions are x1 = 7 and x2 = -3.The equation x² - 4x - 21 = 0 can be solved by factoring it. To factor this equation, we first find two numbers that will multiply to give us -21 and add up to -4. These numbers are -7 and 3. Then we rewrite the equation using -7 and 3 instead of -4x.

The resulting equation is x² - 7x + 3x - 21 = 0.

Next, we group the first two terms and the last two terms to get x(x - 7) + 3(x - 7) = 0.

We factor out the common factor of (x - 7) to get (x - 7)(x + 3) = 0.

We then solve for x to get x = 7 or x = -3. Therefore, the solutions are x1 = 7 and x2 = -3.

I have 500 red balls, 500 green balls, 500 blue balls, and 500 yellow balls in a bin. What is the smallest amount of balls I need to grab so that I am sure I have grabbed 250 balls of one color?

Answers

Answer:

To ensure that you have grabbed 250 balls of one color, you need to use the Pigeonhole Principle. The worst-case scenario is that you grab 249 balls of each color, totaling 996 balls. Therefore, the smallest amount of balls you need to grab is 997, which guarantees that you have grabbed 250 balls of one color.

To explain further, let's consider the worst-case scenario where you grab 249 red balls, 249 green balls, 249 blue balls, and 249 yellow balls. This totals to 996 balls. However, if you grab just one more ball, you will have a total of 997 balls, and since there are only four colors, at least one color will have 250 balls or more. Therefore, by grabbing 997 balls, you can be sure that you have grabbed at least 250 balls of one color.

Answer:

997

Step-by-step explanation:

I multiplied 249 by 4 first. This is because I wanted to find how many balls the person could grab in total without having 250 of the same color.

249*4= 996

However, the question wants to guarantee that one color has 250.

So I did 996+1=997. (which means there could be: 249 red, 249 yellow, 249 green, and 250 blue)

This means that every other color could be at 249, but one would guarantee to be at 250 with 997 pulls
