Given the isosceles trapezoid below, find AG.
Show all the work
We know the width of the rectangle in the middle of the trapezoid is 24 (from the top of the image), so we can subtract that from the bottom width of the trapezoid to get the combined length of the bottom of both triangles.
[tex]40 - 24 = 16[/tex]
Since this is an isosceles trapezoid, both triangle bases are the same length, so we can cut this value in half to get the length of [tex]GT[/tex] and [tex]EF[/tex]
[tex]\frac{16}{2} = 8[/tex]
Finally, we can use the Pythagorean Theorem to find the length of [tex]AG[/tex]:
[tex]AG^{2} + GT^{2} = AT^{2}[/tex]
[tex]AG^{2} + 8^{2} = 10^{2}[/tex]
[tex]AG^{2} + 64 = 100[/tex]
[tex]AG^{2} = 36[/tex]
[tex]AG = 6[/tex]

What is distribution in probability?By displaying the proportion of data points (referred to as "bars") that fall inside a certain range of values, a histogram gives a visual explanation of numerical data. A vertical bar graph and a histogram are comparable.
E(X) = ∑( x ∗ P(x))
Given a probability histogram for a discrete random variable X.
We will drive the P(x) for every value of x.
P(X=1)=0.1
P(X=2)=0.2
P(X=3)=0.3
P(X=4)=0.25
P(X=5)=0.15
Putting these values in a summation equation to find E(x)
E(x) = 1*0.1 +2*0.2 + 3*0.3 + 4*0.25 + 5* 0.15
E(x) = 3.15
Therefore E(x) for the given histogram far random variable x will be 3.15.

In y=mx+b form
Answer:
y = 3x + 3
Step-by-step explanation:
m = 3 because the slope rises 3 and runs 1, therefore 3/1 = 3
b = 3 because the y-intercept is (0,3), therefore y-int = 3
y = 3x + 3
Your job as investigator is to determine who caused this accident. Is the driver responsible , or is the farmer responsible? Read the accounts of the accident, and then answer the following questions 1. Why is the driver unhappy? According to the driver, what caused the accident? (4 points)
The driver was unhappy because she crashed her vehicle and she strongly feels the farmer should be responsible for repairs.
What is stopping distance?Stopping distance can be defined as a measure of the distance between the time when a driver applies a break to stop a vehicle that is in motion and the time when the vehicle completely comes to a stop.
In this scenario, I would say that the driver is responsible for this accident because if she wasn't moving at a high speed, her stopping distance would be very minimal. Thus, she would be able to bring her vehicle to a stop without colliding with or crashing into the fence, immediately she sighted the cows.
Also, I can deduce that the driver was unhappy because she crashed her vehicle and she strongly feels the farmer should be responsible for repairs.

The length of a rectangle is 1 m less than twice the width, and the area of the rectangle is 21 m?. Find the dimensions of the rectangle.
Answer:
length = 6
width = 3 1/2
Step-by-step explanation:
l = length
w = width
l = 2w-1
w(2w-1) = 21
2w² - 1 - 21 = 0
(2w - 7)(w + 3) = 0
w = 7/2 = 3 1/2
find 'l': l = 2(7/2) - 1 = 7-1 = 6

If me and my husband want to save 75000 over the next 13 years and I make 25 dollars and hour and he makes 12 dollars an hour how do I write this in a word problem involving a system of equations
Answer:
The general form of the equation is;
25·x + 12·y = 75,000
x + y ≤ 6,250
When they work the same duration, the time the husband and wife works is approximately 2,071 hours each
When they contribute the same amount, the wife, works for x = 1,500 hours, while the husband works for y = 3,125 hours
Step-by-step explanation:
The amount the couple intends to save in 13 years = $75,000
The amount the wife makes per hour = $25
The amount the husband makes per hour = $12
The number of working hours in 13 years is given as follows;
Total number of hours = 40 hr/week × 52 weeks/year × 13 years = 27,040 hours
However, when the husband alone works, we have;
75,000/12 = 6,250 hours
Let 'x' and 'y' represent the number of hours the wife and husband works respectively, we have the following system of equations;
The general form of the equation is;
25·x + 12·y = 75,000
x + y ≤ 6,250
When the couple work equal times
25·x + 12·y = 75,000...(1)
x = y...(2)
From equation (1), we have;
25·x + 12·y = 75,000
25·x + 12·x = 75,000
x = 75,000/37 ≈ 2,071 hours = y
The number of hours each will work is approximately 2,071 hours
When the husband and wife contribute the same amount, we have;
25·x = 12·y = 75,000/2
x = 75,000/(2 × 25) = 1,500
∴ x = 1,500 hours
The number of hours the wife works = 1,500 hours
y = 75,000/(2 × 12) = 3,125
∴ y = 3,125 hours
The number of hors the husband works = 3,125 hours

Step-by-step explanation:
a trinomial is composed by three monomials.
So only A and B can be correct
the degree of a polynomial is the same of the monomial that compose it with the biggest degree
so the answer is B because the monomial with the biggest degree is 3x^4 (its degree is 4)
Brenda's car averages 375 miles for each 15 gallon tank of gas. How many tanks of gas
will she use on an 1125 mile road trip?
Answer:
3
Step-by-step explanation:
We know that she uses one tank of gas every 375mi, so we can just divide.
1125 / 375 = 3
To check our work we can just multiply.
375 x 3 = 1125.
So she uses 3 tanks on the trip. I hope this helps :)

(3x^2+7)+(2x^2-5x+10)
Answer:
5x² - 5x + 17
Step-by-step explanation:
(3x² + 7) + (2x² - 5x + 10)
Combine the like terms.
3x² + 2x² = 5x²
-5x does not have a like term, so there is no change.
7 + 10 = 17
Combine them, and the final equation is
5x² - 5x + 17.
Answer: 5x² - 5x + 17
Step-by-step explanation:
(3x^2+7)+(2x^2-5x+10)
3x^2 + 2x^2
-5x
7 + 10
5x^2 - 5x + 17
