Answer:
C.
1.8 hours
Step-by-step explanation:
total homework time = math homework time + non math homework time
math homework time = 5 problems * 2 minutes/problem
= 10 minutes
= 10 minutes * 1hr/60 minutes = .167 hrs
non math homework time = 1.6 hours
total homework time = math homework time + non math homework time
total homework time = .167 + 1.6
total homework time = 1.77 hrs
rounding
total homework time = 1.8 hrs
Answer:
y = 3.95(x) + 10
Step-by-step explanation:
The equation of the money spend will expressed as
Total number spend = 3.95 multiply number of DVD rented (x) + 10 membership
Thus equation is y = 3.95(x) + 10
Well, 1 meter is equal to 100 centimeters.
Therefore, 4 meters is equal to 400 centimeters.
400 centimeters is less than 450 centimeters, so 450 centimeters is larger.
Let they be x.
Cost of textbooks + laptops cant greater than total amount.
(cost of 1 textbooks * number of textbooks) + (cost of 1 laptop * number of laptops ≤ 6500
(30*116) + (x*439) ≤ 6500
3480 + 439x ≤ 6500
439x ≤ 3020
x ≤ 6.8(approx)
Last natural number is 6, says, they can buy 6 laptops at max.
