Answer:
91.30 minutes
Step-by-step explanation:
Assuming that when you start charging the phone it had 0% charge, what you should do is a rule of three.
That is, yes in 21 minutes I charge 23%, how long will it take to charge 100%.
charge time charge percentage.
21 minutes 23%
x minutes 100%
Then it would be:
x = 100 * 21/23 = 91.30
So you would have to wait 91.30 minutes to wait for the full charge.
The formula is <span>base × height / 2
So 8.7 x 15.6=135.72 / 2= 67.86

I am taking my first programming course, so my apologies if this is a dumb question/possibly classified by the wrong category on this site. One of the exercise problems I am working on is the following:
Define a function print_total_inches, with parameters num_feet and num_inches, that prints the total number of inches. Note: There are 12 inches in a foot. Ex:
print_total_inches(5, 8) prints:
Total inches: 68
Step-by-step explanation:
Answer:
4 - i
Step-by-step explanation:
Intuitively, the answer will be 4 - i, as the other numbers are too big to have a square as small as 17i. Also, we know that i will not be in the end result, which means that we should have a negative in the result as well.
To test this, we can simply treat 4 and -i as the sides of a right triangle and find the hypotenuse:
So indeed the answer is 4 - i
