Answer:

180 squared ft

Step-by-step explanation

80% = 80/100 = 40/50  =    4/5

L = 15

W= 4/5 of 15 = 12

Area = LxW

Area = 15x12 = 180 squared ft

grin007 [14]

Answer:

what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a  9-month total cost of $327

Step-by-step explanation:

cost = $33 per month + fee  

1.  c(m) = 33m + f

 33(6) + f = 228

198 + f = 228

f = $30 membership fee  

c(m) = 33m + 30

 2.  at 9 months:  33(9) + 30 = $327

hopefully this helps :)

have a nice day !!

What is the area of the figure? Use 3.14 for π. Round to the nearest hundredth if necessary.
vfiekz [6]

Answer:

81.12 cm²

Step-by-step explanation:

The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.

(3.14 * 4²)/2 + (14 * 8)/2 <em>(Work the operations in parentheses first.)</em>

(3.14 * 16)/2 + 112/2

50.24/2 + 112/2 (<em>Divide 50.24 by 2. Do the same for 112.)</em>

25.12 + 56 (<em>Add 25.12 & 56.)</em>

81.12 cm²

The area of the figure is 81.12 cm².
