Answer:
500 minutes
Step-by-step explanation:
100% = x
15% = 75
We multiply 75 by 100 and divide the answer by 15
7500 / 15 = 500 minutes
Answer:
311 
Step-by-step explanation:
Taking a pizza to be a circle
Area of big pizza be x abd are of small pizza be y
hence difference = x-y
Area of a circle = 
where r is the radius
taking 
to be 3.14
hence area x = 3.14 (
*) = 1017.36
Area y = 3.14 (
* )= 706.5
x-y = 1017.36- 706.5 =310.86
310.86

Answer:
0
Step-by-step explanation:
2a+ 2/a =4
Multiply each side by a to clear the fraction
a( 2a+ 2/a) =4*a
Distribute
2a^2 +2 = 4a
Subtract 4a from each side
2a^2 -4a +2 = 4a-4a
2a^2 -4a +2 =0
Divide by 2
2/2 a^2 -4a/2 +2/2 =0/2
a^2 -2a +1=0
Factor
(a-1) (a-1) =0
Using the zero product property
a=1
2a^2 -2/a^2
2(1)^2 -2/1^2
2-2
0
