ivolga24 [154]

Answer:

the answer is 3 feet

Step-by-step explanation:

We can use the volume formula, V =1/2 bhl to find the height of the tent

the volume is $36^{3}$ . The base is 4 and the length is 6 feet

36=1/2 ⋅4⋅h⋅6

A wireless company offers two cell phone plans. For the month of September, Plan A charges $35 plus $0.25 per minute for calls.

Answer:

60 minutes

Step-by-step explanation:

Let the number of minutes be represented as x

For Plan A

Plan A charges $35 plus $0.25 per minute for calls.

$35 + $0.25 × x

35 + 0.25x

For Plan B

Plan B charges $20 plus $0.50 per minute for calls.

$20 + $0.50 × x

20 + 0.50x

For what number of minutes do both plans cost the same amount?

This is calculated by equating Plan A to Plan B

Plan A = Plan B

35 + 0.25x = 20 + 0.50x

Collect like terms

35 - 20 = 0.50x - 0.25x

15 = 0.25x

x = 15/0.25

x = 60 minutes.

Hence, the number of minutes that both plans cost the same amount is 60 minutes
