The answer should be B
Step-by-step explanation:
Answer:
use the formula
Step-by-step explanation:
its 2lw+2lh+2hw
h=5
w=4
l=6
w=61, the equation is w=(456-a-b-c)/2, so the work would look like 456-132-94-108=122/2=61
All you really have to do is divide 80.0 by 16.0
80.0 divided by 16.0= 5
so 5 is your answer!
Answer:
Lesser than 6.9 minutes
Step-by-step explanation:
Let m represent the number of minutes of phone use with either plan A or plan B.
In plan A, the customer pays a monthly fee of $35 and then an additional 9 cents(9/100 = $0.09) per minute of use. This means that the total cost of m minutes would be
0.09m + 35
In Plan B, the customer pays a monthly fee of $55.70 and then an additional 6 cents(6/100 = $0.06) per minute of use. This means that the total cost of m minutes would be
0.06m + 55.70
Therefore, for the amounts of monthly phone use for which Plan A will cost less than Plan B, it becomes
0.09m + 35 < 0.06m + 55.70
0.09m - 0.06m < 55.70 - 35
0.03m < 20.7
m < 20.7/3
m < 6.9
