Answer: 48.84
Step-by-step explanation:
First, find the perimeter of the rectangle. 12+12+3+3=30ft. Next, find the perimeter of the semicircles. You can tell that if you put the semicircles together it would be a full circle. The formula for the perimeter of a circle is r2pi. The radius times 2 would be 6. Pi is approximately 3.14. 6 times 3.14 is 18.84. 18.84+30=48.84ft. Hope this helped :)
Answer:
C.)
Step-by-step explanation:
4x -20x -5b -x +2=-17x -8
-17x-5b+2=- 17x-8
+17x +17x
-5b +2= -8
-2 -2
-5b = -10
b= 2
30 + 20 + 30 + 20 = 100
30 x 10% = 3 + 30 = 33
20 x 5% = 1 + 20 = 21
33 + 21 + 33 + 21 = 108
100 / 108 = 0.925925926 = 0.93 = 93%
100% - 93% = 7%
7% increase
7/10 is 0.7
0.7 x 16 yields 11.2
11.2 is also 11 1/5
or 56/5
Answer:
44
Step-by-step explanation:
x^2 + y^2 = 14
(x-y)^2 x^2 + y^2 - 2xy = 14 -2 * (-15) = 44
