First you would change the time from minutes to seconds by multiplying 4 by 60 because there are 60 seconds in a minute. After finding that (4*60=240) you would subtract the remaining time (12 seconds) from the total time (240 seconds). You would subtract the remaining time from the total time (228 seconds). Using that you would use the ratio time used/total (228/240). Divide that out and multiply by 100 to get 95%. I hope that helps!
Answer:
Radius = 12 cm
Step-by-step explanation:
Given:
Volume of the cylinder is, 
cm³
Height of the cylinder, 
cm
Let the radius be 
Using the formula for volume of cylinder,
Plug in 3165.12 for 
, 7 for 
and solve for .
Therefore, the radius of the cylinder is nearly 12 cm.
<span>We can reduce this fraction, 875 / 1000 to lowest
terms by dividing both the numerator and denominator by 125 ;
</span><span>Why divide by 125? 125 Greatest Common Factor (GCF) of the numbers 875 and 1000.
So, this fraction reduced to lowest terms is 7 / 8 ;
In the same way, 35 / 100 is reduced to lowest terms as 7 / 20 ;</span>
Answer:
(x+5i)(x-5i)
Step-by-step explanation:
We use imaginary numbers to solve that. since i = sqare root of -1 so i * i = -1.
