If you're rounding to the nearest 100th the total would be 100. 422 would round to 300 and 284 would be rounded to 300 which equals 100.

X = measure of each of the legs
"perimeter is 8 more than 2 times one of the legs" ---> P = 2x+8
P = 28 is the given perimeter

So,
P = 2x+8
28 = 2x+8
2x+8 = 28
2x = 20
x = 10

If x = 10, then the two legs add up to x+x = 10+10 = 20
Leaving P-20 = 28-20 = 8 inches left over for the base

You have the correct answer (choice D, 8 inches) though your steps are a bit confusing at some parts. Such as the part where you wrote 2x = 10 twice. I think I know what you were trying to say.

Kylie started basketball practice at 2:30 p.m and finished at 6:00 p.m how long was kylie at basketball practice
Sav [38]

Answer:

3 hours and 30 minutes

Step-by-step explanation:

Since both of these times are in the P.M., each hour has 60 minutes and 2:30 is half, add 30 minutes to get 3:00 P.M. and then add 3 hours to get 6:00 P.M. . 3 hours and 30 minutes added to 2:30 P.M. equals 6:00 P.M. :)

There are 60 feet between the bases on a softball diamond. How far does a catcher throw drone home plate to second base
mixas84 [53]

Answer: 12\sqrt{5}

Required theorem:

Pythagorean theorem = a^2 + b^2=c^2

In other words, one side length squared + another side length squared = the middle lined squared.

Step-by-step explanation:

60^2+60^2 = c^2\\\\360+360=c^2\\\\720=c^2\\\\\ \sqrt{c^2} =\sqrt{720}\\\\c=+/- 12\sqrt{5}

We can only have a positive distance so your final answer is :

12\sqrt{5}
