Answer:
84.8125 ft^2
Step-by-step explanation:
The area of the rectangle is
A = l*w
A = 5*15 = 75
The area of the semicircle
A = 1/2 pi r^2
We need the radius = 5/2 = 2.5
1/2 (3.14)(2.5) ^2
9.8125
Add the areas together
75+9.8125
84.8125
Answer:

Answer
two-thirds
Step-by-step explanation:
8 over 1 2simplified is 2 over 3
Answer:
x = -4
Step-by-step explanation:
divide both sides by 3 to get x = -4
If x=16-4y then in your other equation 3x+4y=8 you can put that where x is to get:
3(16-4y)+4y=8
Then multiply brackets to get:
48-12y+4y=8
Simplify:
48-8y=8
Rearrange:
40=8y
Divide through by 8:
y=5
Then put y=5 back into x=16-4y to get x:
x=16-4(5)
x=16-20
x=-4
