use the formula for the area of a trapezoid A=h(b1+b2/2), were area is A b1 and b2 are the length of the base and h is the hight
Colt1911 [192]

Answer: 300 yards

Step-by-step explanation:

Since b1 is equal to 14 yds and b2 is equal to 26 yds we can plug that into the equation below (in the image).

b1 + b2 = 14 + 26 = 40 yards

Now that we have found (b1 + b2), you can multiply that by h (the height of the trapezoid) which is 15, so we get 40 x 15 = 600.

In a lot of area equations, you will have to divide by two like in the trapezoid equation. Divide our number (600) by 2, so we get 600 ÷ 2 = 300.

300 yds is your final answer.

Hope this helps!

Find the slope of the line through each pair of point
Blizzard [7]

Answer:

slope = \frac{2}{7}

Step-by-step explanation:

Calculate the slope m using the slope formula

= (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 6, 3) and (x₂, y₂ ) = (1, 5)

m = \frac{5-3}{1+6} = \frac{2}{7}

A group 6 students was asked, how many hours did you watch television last wee? Here are their responses. 20, 5, 7, 17, 16, 15,
Sindrei [870]

Answer:

13.3

Step-by-step explanation:

There is an equation that helps

mean= (All of the numbers in the data added) divided by (the number of numbers in the data)

What that mean is:

1.) Add 20, 5, 7, 17, 16, and 15

2.) divided by 6 (because there is 6 numbers in the data)

3.) round it to the nearest number (numbers from the one's place being 4-0 means go back or 5-9 means go forward a number)

which in this case it should be 13.33333...=13.3

Why is apr an important tool for consumers
My name is Ann [436]

Answer:

APR, or annual percentage rate, is your interest rate stated as a yearly rate. An APR for a loan can include fees you may be charged, like origination fees. APR is important because it can give you a good idea of how much you'll pay to take out a loan.
