Answer:
Total Area = 236.715 sq ft
Step-by-step explanation:
this is a composite figure made up of a circle and a rectangle; find the area of each and then add them together
A(circle) = πr²
= π(7.5²)
= 176.715
A(rectangle) = 15(4) which is 60
Total Area = 236.715 sq ft
Y = -2x² + 8x - 18
x = -b/2a
x = -8/2(-2)
x = -8/-4
x = 2
y = -2x² + 8x - 18
y = -2(2)² + 8(2) - 18
y = -2(4) + 16 - 18
y = -8 - 2
y = -10
(x, y) = (2, -10)
Vertex: (2, -10)
Axis of Symmetry: x = 2
<span>For the answer to the question above,
4 shovels of sand are used for every 5 shovels of gravel
4s : 5g
How many shovels of gravel are needed for 64 shovels of sand?
64s : Xg
We need to calculate the value of X
4s : 5g
</span><span>64s : Xg
4s.Xg = 5g.64s
X = (5g*64s)/4sg
= 5*64/4
= 5*16
= 80
80 shovels of gravel are needed.</span>
15. The answer that best fits the question would be the "First" option. the ( and ) are just things to say do the inner work first, then multiply.
16. The Third option is the answer that best fits the question. She is trying to find how many time she did something, so multiplication would be the answer.
Hope this helps!
