Answer:

Step-by-step explanation:

As  portion of the vegetables weights 1/4 pound and totals **15/16 pounds , the can has **3 and 3/4 servings** of veggies.

A pound is a unit of weight or mass measurement. The Latin word "libra," which means "weight" or "balance," denotes a measurement system employed in ancient Rome and which is equivalent to around 12 ounces.

Mass is the quantity of matter in a thing, whereas weight is the force of gravity acting on the object

Each portion of the vegetables weights 1/4 pound and totals **15/16 pounds** in the can. We must divide the can's overall weight by the weight of one serving to determine how many servings of veggies are included therein.

We thus have:

'''The can weighs 15/16 pounds in total.

Weight of one serving is one-fourth of a pound.

We divide the entire weight of the can by the weight of one serving to get how many servings are in it:

``` (15/16) ÷ (1/4) = (15/16) × (4/1)

= 60/16 = 3 3/4 ```

As a result, the can has **3 and 3/4 servings** of veggies.

Answer:

Cosine, sine, and tangent are trigonometric functions used in mathematics and geometry to calculate angles and sides in right triangles.

Here is a brief explanation of each:

Cosine (cos): The cosine of an angle in a right triangle is defined as the adjacent side length divided by the hypotenuse length. In other words, it represents the ratio of the length of the adjacent side to the angle to the length of the hypotenuse. It is usually abbreviated as cos.

Sine (sin): The sine of an angle in a right triangle is defined as the opposite side length divided by the hypotenuse length. In other words, it represents the ratio of the length of the opposite side to the angle to the length of the hypotenuse. It is usually abbreviated as sin.

Tangent (tan): The tangent of an angle in a right triangle is defined as the opposite side length divided by the adjacent side length. In other words, it represents the ratio of the length of the opposite side to the angle to the length of the adjacent side. It is usually abbreviated as tan.

To solve questions that involve these functions, you need to know at least two values of a right triangle, such as the lengths of two sides or one side and an angle. Then you can use the trigonometric function and the given values to calculate the missing side or angle.

For example, if you know the length of the hypotenuse and one acute angle of a right triangle, you can use the sine or cosine function to calculate the length of one of the other sides. If you know the length of one side and one acute angle, you can use the tangent function to calculate the length of the other side.

There are also trigonometric identities and equations that can be used to simplify or solve more complex problems involving these functions.

There are 11 squares containing the black center square in the 5x5 grid.

To find the number of squares that contain the black center square, we'll consider the sizes of the squares and their positions in the 5x5 grid.
The black center square is a 1x1 square itself, so that's 1 square.
For 2 x 2 squares containing the center square, there are 4 possible positions (the center square can be in any corner). So, that's 4 squares.
For 3x3 squares containing the center square, there is only 1 possible position (the center square is exactly in the middle). So, that's 1 square.
4. For 4x4 squares containing the center square, there are 4 possible positions (the center square can be in any corner). So, that's 4 squares.
5. For 5x5 squares containing the center square, there is only 1 possible position (the center square is exactly in the middle).

So, that's 1 square.

The equation (5 x 10⁶) (9 × 10⁻²) = 6 x 10⁴ when written in scientific notation. The value of b is 5 and the value of n is 4.

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in standard decimal form. The number is written in the form of a number between 1 and 10 multiplied by a power of 10.

The value of b in this equation is 5. This is because the decimal points in both terms must be aligned in order to multiply them together.

The decimal points in each term are 6 and 2, respectively.

Since 6 is greater than 2, the decimal point for the total must be aligned with 6.

This means that the number 5 must be multiplied by 10⁶, resulting in b being 5.

The value of n in this equation is 4. This is because when the two terms are multiplied together, the exponents must be added.

The exponents of 10 in each term are 6 and -2, respectively.

When these are added together, they equal 4, resulting in the exponent of 10 in the new term to be 4.

a) The percentage of batteries the company expects to replace is:

0.1271 * 100% = 12.71%

b) The company should guarantee the batteries for 34 months (rounded to the nearest month) to ensure that refunds are not made for more than 9% of its batteries under the full-refund guarantee policy.

(a) Let X be the random variable representing the life of a battery. We want to find the probability that a battery fails within 36 months after purchase, which is equivalent to finding P(X ≤ 36).

Using the normal distribution formula with mean μ = 44 months and standard deviation σ = 7 months, we have:

Z = (X - μ) / σ = (36 - 44) / 7 = -1.14

Using a standard normal table or calculator, we find that the probability of a standard normal variable being less than or equal to -1.14 is 0.1271. Therefore, the percentage of batteries the company expects to replace is:

0.1271 * 100% = 12.71% (rounded to two decimal places)

(b) Let Y be the random variable representing the length of the guarantee period in months. We want to find the value of Y such that P(X ≤ Y) = 0.09, where X has the same normal distribution with mean μ = 44 months and standard deviation σ = 7 months.

Using the inverse normal distribution formula with mean μ = 44 months and standard deviation σ = 7 months, we have:

Z = invNorm(0.09) = -1.34

where invNorm is the inverse normal function. Solving for Y, we have:

(Y - μ) / σ = Z

(Y - 44) / 7 = -1.34

Y - 44 = -1.34 * 7

Y ≈ 34.42

Answer: The formula for the surface area of a cylinder is:

SA = 2πr^2 + 2πrh

where SA is the surface area, r is the radius, and h is the height.

In this case, we know that the surface area is 936π square meters and the radius is 13 meters. So we can plug those values into the formula and solve for h:

936π = 2π(13^2) + 2π(13)(h)

Simplifying:

936π = 338π + 26πh

936π - 338π = 26πh

598π = 26πh

h = 598/26 = 23

This equation tells us that the distance the bus travels is directly proportional to the time it travels at a constant speed of 15m/s.

What is speed?

Speed is the method of measuring how quickly an object moves from one place to another. It is a scalar quantity that expresses the rate of change of distance over time. In other words, it is the distance traveled per unit of time.

If the bus is traveling at a constant speed of 15m/s, then its acceleration is 0m/s². Therefore, we can use the formula for distance traveled at constant speed:

distance = speed × time

In this case, the speed of the bus is 15m/s, so the equation for the distance the bus travels in time (t) is:

distance = 15t

This equation tells us that the distance the bus travels is directly proportional to the time it travels at a constant speed of 15m/s.

Let x be the number of laps Jada plans to swim.

According to the problem, 4 laps is 2/5 of the number of laps she plans to swim, so we can write:

4 = 2/5 * x

To solve for x, we can first multiply both sides by the reciprocal of 2/5, which is 5/2:

4 * 5/2 = x

Simplifying the left side:

10 = x

Therefore, Jada plans to swim 10 laps.

The proof that the table has a constant ratio is shown below

From the table of values, we have the following parameters that can be used in our computation:

f(x + 1) = ab^(x + 1)

f(x + 2) = ab^(x + 2)

f(x + 3) = ab^(x + 3)

When divided, we get the ratio r

So, we have

r = f(x + 3)/f(x + 2) = f(x + 2)/f(x + 1)

This gives

ab^(x + 3)/ab^(x + 2) = ab^(x + 2)/ab^(x + 1)

Divide through by a

b^(x + 3)/b^(x + 2) = b^(x + 2)/b^(x + 1)

Using the law of indices, we have

b^(x + 3 - x - 2) = b^(x + 2 - x - 1)

The possible dimensions of the plot are:

Length = 25.6 meters, width = 9.2 meters

What is quadratic equation?

It's a second-degree quadratic equation which is an algebraic equation in x.

Let the length of the rectangular plot be L meters and the width be W meters. Then the perimeter of the plot is:

P = 2L + W

Since there are only three sides to the fence, we can set the perimeter equal to the length of the fencing:

2L + W = 44

Solving for W, we get:

W = 44 - 2L

The area of the plot is given as 210 square meters:

L * W = 210

Substituting for W, we get:

L * (44 - 2L) = 210

Simplifying and rearranging, we get a quadratic equation:

2L² - 22L + 105 = 0

Using the quadratic formula, we can solve for L:

L = (22 ± √(22² - 4(2)(105))) / (2(2))

L = (22 ± 2√34) / 4

L = 11/2 ± √34/2

We discard the negative solution, so:

L = 11/2 + √34/2 ≈ 9.2 meters

Now we can use the equation W = 44 - 2L to find the corresponding width:

W = 44 - 2(9.2) = 25.6 meters

Therefore, the possible dimensions of the plot are:

Length = 9.2 meters, width = 25.6 meters

Length = 25.6 meters, width = 9.2 meters

We can simplify both sides of the equation by finding a common denominator for the fractions:

2/3 + (3/4 + 1/5) = (2/3 + 3/4) + 1/5

Multiplying 2/3 by 20/20, we get:

40/60 + (3/4 + 1/5) = (2/3 + 3/4) + 1/5

Multiplying 3/4 by 15/15, we get:

40/60 + 45/60 + 1/5 = (2/3 + 3/4) + 1/5

Combining the first two terms on the left-hand side, we get:

85/60 + 1/5 = (2/3 + 3/4) + 1/5

Simplifying the fraction 85/60, we get:

17/12 + 1/5 = (2/3 + 3/4) + 1/5

Multiplying 2/3 by 4/4, we get:

17/12 + 1/5 = (8/12 + 9/12) + 1/5

Combining the fractions in the parentheses, we get:

17/12 + 1/5 = 17/12 + 1/5

Since both sides of the equation are equal, we have verified that the associative property of addition holds for the given expression:

Adjacent: side MN, which is adjacent to angle M.

Hypotenuse: side LN, which is the longest side and opposite to the right angle N.

Using the Pythagorean theorem, we can find the length of the hypotenuse LN:

[tex]LN^2 = LM^2 + MN^2 \\LN^2 = 10^2 + 6^2\\LN^2 = 100 + 36\\LN^2 = 136LN = sqrt(136) = 2*sqrt(34)[/tex]

Now, we can use the tangent formula:

tan(M) = opposite/adjacent = LM/MN

tan(M) = 10/6 = 5/3
