Answer:
Step-by-step explanation:
step 1
Alex’s printer
we know that
print 8 photos in 12 minutes
so
by proportion
Find how long will it take the printer to print 120 photos
step 2
Khalil’s printer
we know that
print 24 photos in 1 hour (60 minutes)
so
by proportion
Find how long will it take the printer to print 120 photos
step 3

Answer:
March
Step-by-step explanation:
It’s March because in February there were 45 or so students, but then in March it went all the way up to 120. So, 120 - 45 = 75, which is the most amount of students increasing in a month.
I hope this helped and it wasn’t so confusing!!
Answer:
first one is correct
Step-by-step explanation:
Set up two equation using volume= pir^2h. you know the r will be constant 5 and pi is 3.14. so the height of full cylinder would be solved by 471= (3.14) 5^2 *h
Now the height of the water is similar using the same equation but setting it equal to the volume of the water. 314= (3.14)5^2*h. solve both for h and find the difference will be your answer
