Answer:
2644.415 feet spuared
Step-by-step explanation:
I think the attached photo is your full question, and my answer:
We need to find:
- the area of the pool = π = 3.14* = 1319.585 feet spuared.
- The area of the triangular fence = 1/2* 84*92 = 3964 feet spuared
So, the area of the backyard which is not covered by the pool is:
<em>The area of the triangular fence - the area of the pool</em>
= 3964 - 1319.585
= 2644.415
Hope it will find you well.
There are 47 dimes and 23 quarters.
Step-by-step explanation:
Total amount = $10.45 = 10.45*100 = 1045 cents
Total coins = 70
1 dime = 10 cents
1 quarter = 25 cents
Let,
Dimes = x
Quarters = y
According to given statement;
x+y=70 Eqn 1
10x+25y=1045 Eqn 2
Multiplying Eqn 1 by 10;
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 15;
Putting y=23 in Eqn 1
There are 47 dimes and 23 quarters.

21 and -14 add to 7 and sum to -294 when multiplied
Answer:
The arrow can be broken into a rectangle and a triangle.
And the area of the arrow is 22 ft^2
Step-by-step explanation:
Area of the rectangle:
length • width = 7 • 2 = 14 ft^2
Area of the triangle:
(base • height) / 2
You must add 1 + 2 + 1 in order to get the base which is 4
And to get the height, you must do 11 - 7 = 4 (height)
(4 • 4) / 2 = 8 ft^2
Add both areas together to get the area of the arrow:
14 ft^2 + 8 ft^2 = 22 ft^2
Hope this helps!
