Answer:

Perimeter= 44.2 inches

Area= 70 inches squared

Step-by-step explanation:

Perimeter- Add all your sides together (10+ 17.2+2+3+7+5=44.2)

Area- 1/2bh (b=base, h=height)

Your base is the bottom of the triangle, so 2+7+5=14.

14 is your base

Your height is the 10

1/2 *14*10

1/2 of 14 is 7

7*10= 70

Don't forget to write inches squared or it will be wrong

Hope this helps :)

Answer:

Perimeter: 47.2 in Area: 49² in

Step-by-step explanation:

First to find the perimeter you have to add 17.2 with 10, 2, 3, 3, 7, and 5. You get 47.2 in as your perimeter. To get the area, first you multiply 10 by 14 and you get 140. Now divide that by 2 to get 70. Now multiply 7 by 3 to get 21. Subtract 21 from 70 to get 49² as your answer

Dianna and Becky were playing on the same soccer team and took turns being goalie. They stoped 9 out of 10 shots made against th

vitfil [10]

Answer:

27 balls

Step-by-step explanation:

If Dianna and Becky stopped 9 out of 10 shots made against them.

It means they allowed in 1 out of 10 shots made against them.

This is best solved using ratios

Proportion of Shots Stopped : Proportion of Shots allowed=9:1

If the other team scores 3 points, it means the number of shots allowed =3

Let x be the number of shots stopped

Number of Shots Stopped : Number of Shots allowed=x:3

Therefore:

9:1=x:3

$\frac{9}{1}=\frac{x}{3}$

Cross multiplying

x=9 X 3 =27

Dianna and Becky stopped 27 balls from going into the net,
