1 and half hour
= 60 minutes+ 30 minutes
= 90 minutes
Now,
Uzanne need 15 minutes to do 10 problems
Uzanne need 1 minute to complete 10/15 problems
Uzanne need 90 minutes to do
= (10/15)*90
=(2/3)*90
=2*30
=60 problems
Answer:
y = (8/5)x - 3
Step-by-step explanation:
Slope:
(-19-5)/(-10-5)
= -24/-15 = 8/5
y = (8/5)x + c
5 = (8/5)(5) + c
c = 5 - 8 = -3
y = (8/5)x - 3
50 is
62.5% of 80
Divide 50 by 80 to get the decimal:

Multiply the decimal by 100:
C, as this is the answer where the outcome is unsure, dependant on other factors.
