Answer with Step-by-step explanation:

The area of trapezoid is given by:

A=\dfrac{1}{2}\times (sum\ of\ bases)\times height

Here we are given Area=390 km²

Sum of bases=(23+29) km

                      = 52 km

We have to find the height of trapezoid

Putting all the given values in the formula of area of trapezoid

390=\dfrac{1}{2}\times 52\times height

390=26×height

height=15

Hence,height of trapezoid is:

15 km

Hello!

To find the area of a trapezoid you use the equation

A =  \frac{a+b}{2} h

Put in the values you know

390 =  \frac{23+29}{2} h

Add

390 = \frac{52}{2} h

Divide

390 = 26 * h

Divide both sides by 26

15 = h

The answer is 15km

Hope this helps!

Please help with this math question I really need to do this test before I fail thank you!!

Answer:

G- 1/5

Step-by-step explanation:

When doing probability questions, you want to take the amount of what you are looking for and put it over the total. In this case, the total amount of t-shirts would be 15. If we are looking for the sports t-shirts, the fraction would be 3/15, which then simplifies down to 1/5.

Hope this helps! :)
