Sean is correct, because he adds 0 to -100, which equals to -100
<em />I dont think Candice is correct however, since you cannot repeat the numbers
(and adding negative numbers is incorrect im assuming)
hope this helps
Answer:
50.24 yd^2
Step-by-step explanation:
The area of a circle can be found using:

First, we need to find the radius. We have the diameter. The diameter is twice the radius, or
d=2r
We know that the diameter is 8, so we can substitute 8 in for d
8=2r
Since we are trying to find r, we need to get r by itself. To do this, divide both sides by 2.
8/2=2r/2
4=r
Now we know the radius, and can substitute 4 in for r. Also, we can substitute 3.14 in for pi.

a=3.14*4^2
Solve the exponent
a=3.14*16
Multiply
a=50.24
The area is 50.24 yards^2
Answer:$205-ddd=$160
Step-by-step explanation:
It just depends on the grade level but that is a standard equation. The ddd would stand for dollars spent at the park. If you did $205-$160 you’d get $45. So she would have spent $45 at the park :)
Answer:
x=2
Step-by-step explanation:
Set up a proportion. Let h = the statue height. h/statue shadow = boy height/boy shadow.
h/25 = 4.5/3.6
Cross multiply and solve for h.
