What is triangle?
A triangle is a three-sided polygon, which is a flat shape with straight sides. It is a basic shape in geometry and has many interesting properties that are useful in mathematics and other fields.
The formula for the area of a triangle is A = 1/2 * b * h, where A is the area, b is the length of the base, and h is the height of the triangle.
In this case, we know that the area of the triangle is 21 in² and the height is 7 in. So we can substitute these values into the formula and solve for the base:
21 = 1/2 * b * 7
Multiplying both sides by 2:
42 = b * 7
Dividing both sides by 7:
6 = b
Therefore, the length of the base is 6 inches.

find the areas of the sectors formed by angleDFE. Round your answers to the nearest hundredth
The area of the sector formed by angle DFE is approximately 3.29 square feet.
What is area of the sector?
To find the area of a sector of a circle, we need to know the central angle that defines the sector and the radius of the circle. We can then use the formula:
Area of sector = (central angle / 360 degrees) x π x (radius)²
In this case, we are given that the radius of the circle is 4 feet and the central angle that defines the sector is 75 degrees. Therefore, the area of the sector can be calculated as:
Area of sector = (75 / 360) x π x (4)²
= (0.2083) x π x 16
= 3.29 square feet (rounded to the nearest hundredth)
Therefore, the area of the sector formed by angle DFE is approximately 3.29 square feet.

29 + 14 = 44 by decomposing numbers to add and make a new 10.
Describe Decomposition of numbers?Decomposition of numbers involves breaking a number down into its constituent parts or smaller numbers that add up to the original number. This can be done in different ways depending on the purpose and context of the problem.
For example, one common way of decomposing a number is by place value. In this case, the number is broken down into its digits, which represent different powers of ten. For instance, the number 562 can be decomposed into 500 + 60 + 2.
Another way of decomposing numbers is by factoring. In this case, the number is expressed as a product of its factors. For example, the number 12 can be decomposed as 2 x 2 x 3.
Decomposing numbers is a useful skill in many areas of mathematics, including arithmetic, algebra, and geometry. It is often used to simplify problems, make computations easier, and facilitate further analysis.
To decompose 29 to make a new 10, we can break it into 9 and 20. Then, to decompose 14 to make a new 10, we can break it into 6 and 8.
So, we have:
29 + 14 = (9 + 20) + (6 + 8)
Now, we can regroup the numbers to make a new 10:
= (9 + 1) + (20 + 6) + 8
= 10 + 26 + 8
= 44
Therefore, 29 + 14 = 44 by decomposing numbers to add and make a new 10.

I’m thinking of three numbers: X, Y, and Z. We have X ≤ Y ≤ Z. The median of the
three numbers is 90, the mean of the three numbers is 92, and the range of the three
numbers is 6. What are the values of X, Y, and Z? Show your work
The X, Y, and Z values are 84, 90, and 90, respectively. To answer this question, we need to understand the meaning of the words "median", "mean" and "range".
What is median?Median is the middle number of a set of numbers - it is the number in the middle when the numbers are ordered from smallest to largest.
Since the median is 90, this means that Y (the mean number) is 90. Since the average is 92, this means that the sum of the three numbers is 276 (92 x 3). The interval is 6, which means that the difference between the largest number and the smallest number is 6.
To solve for X and Z, we can use the equation X Y Z = 276. We know that Y is 90, so we can plug 90 into Y:
X 90 Z = 276
Then we can subtract 90 from both sides to find the value of X and Z:
X Z = 186
Since the range of the three numbers is 6, this means that X and Z must be 6 plus. The only two numbers that differ by six and add up to 186 are 84 and 90.
Therefore the X, Y, and Z values are 84, 90, and 90, respectively.

If f(x)=3x-5, g(x)=7x-3, find (f+g)(x) and (f-g)(x
Answer:
Step-by-step explanation: To find (f+g)(x), we simply add the two functions:
(f+g)(x) = f(x) + g(x)
= (3x - 5) + (7x - 3)
= 10x - 8
Therefore, (f+g)(x) = 10x - 8.
To find (f-g)(x), we subtract g(x) from f(x):
(f-g)(x) = f(x) - g(x)
= (3x - 5) - (7x - 3)
= -4x - 8
Therefore, (f-g)(x) = -4x - 8.
Mrs. Andretti is having new drapes made for her living
room. The cost of the fabric is $15 per yard. The fee to
make and hang the drapes is $250. She uses the expression
15x + 250 to calculate the total cost of the drapes. Mrs.
Andretti states that x represents the total cost of the fabric.
Is she correct?
• Yes, x represents the total cost of the fabric.
O No, x represents the total cost of the drapes.
• No, x represents the total yards of fabric used.
O No, x represents the total amount of fabric she
already has.
Fabric cost ($15 per yard) and curtain making and hanging ($250). x represents the total cost of the fabric and Mrs. Andretti can use the formula 15x to calculate the fabric cost and add the $250 fixed charge to get the total cost of the curtain.
Why do we determine costs?Cost computation helps in deciding on pricing, manufacturing output, and sales. It also helps in figuring out the costs of the products and services the company sells.
X does not represent the cost of fabric. X represents the number of yards of fabric used.
15x + 250
Could be read as ($15 × # of yards) + $250
She must therefore pay $15 per yard of cloth in addition to the $250 base cost of having them produced and hung.
She may indicate the price of fabric with an additional variable.

Can the sides of a right triangle have lengths 5, 15, and √250? Explain.
A triangle must have a third side that is bigger than the sum of any two of its sides. There cannot be a triangle with these side lengths because in this instance, 5 + 15 = 20 is not greater than 250.
Application of Pythagoras theoremTo check whether the given lengths can form the sides of a right triangle, we need to check if they satisfy the Pythagorean theorem, which states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
Let's label the sides of the triangle as a, b, and c, where c is the hypotenuse. Then, the Pythagorean theorem can be written as:
a^2 + b^2 = c^2
Plugging in the given values, we get:
5^2 + 15^2 = (√250)^2
Simplifying the left-hand side, we get:
25 + 225 = 250
This is not true, since 25 + 225 = 250 does not hold. Therefore, the given lengths cannot form the sides of a right triangle.
In fact, we can see that the given lengths violate the triangle inequality, which states that the sum of any two sides of a triangle must be greater than the third side. In this case, 5 + 15 = 20 is not greater than √250, so a triangle with these side lengths cannot exist.

Two skaters are practicing at the same time on the same rink. A coordinate grid is superimposed on the ice. One skater follows
the path y = - 3x + 8, while the other skater follows the curve y= - 2x^2 + 7x. Find all the points where they might collide if they
are not careful.
Answer: To find the points where the two skaters might collide, we need to find the values of x and y that satisfy both equations:
y = -3x + 8
y = -2x^2 + 7x
We can set the two equations equal to each other and solve for x:
-3x + 8 = -2x^2 + 7x
This simplifies to:
2x^2 - 10x + 8 = 0
Dividing both sides by 2, we get:
x^2 - 5x + 4 = 0
Factoring the left side, we get:
(x - 1)(x - 4) = 0
So the solutions for x are x = 1 and x = 4.
To find the corresponding values of y, we can substitute these values of x into either equation. Let's use y = -3x + 8:
When x = 1, y = -3(1) + 8 = 5
When x = 4, y = -3(4) + 8 = -4
Therefore, the two skaters might collide at the points (1, 5) and (4, -4).

Rewrite quadratic function in standard form
Since the function is already in standard form (ax^2 + bx + c form) you don't have to change anything and simply rewrite it.
For the vertex, if you have a quadratic function in standard form -b/2a is the x value of the vertex.
-b/2a = -4/(2(2)) = -1
Since we now know the x-value of the vertex we can plug it into the function to find the corresponding y-value.
h(-1) = 2(-1)^2 + 4(-1) - 10 = -12
So, the vertex is at (-1,-12)
Make an expression with 4 terms where 3 of them are like terms.

Answer:
Step-by-step explanation:
An example of an expression with 4 terms where 3 of them are like terms is:
$5x^2 + 7x - 2x^2 + 3x$
To rewrite this expression by combining like terms, we add the coefficients of the terms with the same variables raised to the same power. In this case, the two terms with $x^2$ are like terms, so we can add their coefficients:
$5x^2 - 2x^2 + 7x + 3x = 3x^2 + 10x$
The resulting expression has 2 terms.

For a randomly selected morning, what is the probability that John’s drive to work will take between 36 and 40 minutes?
The probability that John's drive to work will take between 36 and 40 minutes is 0.3413.
What is Probability?Probability is the measure of how likely an event is to occur. It is expressed as a number between 0 and 1, where 0 indicates that the event is impossible and 1 indicates that the event is certain to occur. Probability is used in many areas of life, such as gambling, finance, and science. It is also used to make decisions in everyday life, such as estimating the likelihood of rain or the chance of winning a bet.
Using the normal distribution, the probability of John's drive taking between 36 and 40 minutes can be calculated using the standard normal distribution table. The formula for calculating the probability is: P(x<X<y) = P(y) - P(x).
For the given problem, the lower boundary is 36 minutes and the upper boundary is 40 minutes. Using the standard normal distribution table, the probability of John's drive taking between 36 and 40 minutes can be calculated by subtracting the probability of 36 minutes from the probability of 40 minutes. This gives us a probability of 0.3413.
Therefore, the probability that John's drive to work will take between 36 and 40 minutes is 0.3413.

The probability that John's drive to work will take between 36 and 40 minutes can be calculated using a normal distribution table. The mean of the distribution is µ = 38 minutes, and the standard deviation is σ = 5 minutes.
To calculate the probability, we need to convert the given range (36 minutes to 40 minutes) into standard normal scores. This is done by subtracting the mean (µ = 38 minutes) from the lower bound (36 minutes) and then dividing by the standard deviation (σ = 5 minutes). The result is a standard normal score of -0.4. The same calculation is carried out for the upper bound (40 minutes) and the result is a standard normal score of 0.4.
Using a normal distribution table, we can then determine the probability that John's drive to work will take between 36 and 40 minutes. This probability is equal to the area under the normal curve between the two standard normal scores of -0.4 and 0.4. The result is a probability of 0.3829.

15 = 100 * r * 3
Solving for r, we get:
r = 15 / (100 * 3) = 0.05
Therefore, the interest rate on the savings account is 5%.

Answer: here it is.
Step-by-step explanation:
what is the value of x
The value of the variable x for the similar triangles is equal to 25
How to evaluate the value of x for the similar trianglesThe triangles BDR and QDC are similar, this implies that the length DC of the smaller triangle is similar to the length DR of the larger triangle
and the length DQ of the smaller triangle is similar to the length DB of the larger triangle
so;
x/(15 + x) = 40/64
64x = 40(15 + x) {cross multiplication}
64x = 600 + 40x
64x - 40x = 600 {subtract 40x from both sides}
24x = 600
x = 600/24
x = 25
Therefore, the value of the variable x for the similar triangles is equal to 25
