Answer:
8.82
Step-by-step explanation:
Add the basketball and airpump together and subtract from 50
Surface Area (SA) of a Cylinder formula:
SA = 2*pi*r*h+2*pi*r^2
If you fill in the formula:
SA = 2*3.14*2*9+2*3.14*2^2
Simplify:
SA = 6.28*18+6.28*4
SA = 113.04 + 25.12
SA = 138.16 in
I hope I helped
If its wrong I'm super duper extra sorry!
6/2*3 / 3(3)
First simplify the numerator: 6/2*3 = 3*3 = 9
Next simplify the denominator: 3(3) = 3*3 = 9
So you have 9/9, which equals 1.
The 3rd answer is correct.
If the battery was used for 11 hours, then the value of x we use is 11
Subtitute x with 11 in the equation
y = 100 - 8.9x
y = 100 - 8.9(11)
y = 100 - 97.9
y = 2.1
The remaining power is 2.1%
the answer is option b
