tensa zangetsu [6.8K]

Answer:

5 hours

Step-by-step explanation:

First, you set the equations equal, so 20h=17h+15

Second, you isolate the h, so you would subtract 17h from both sides, giving you 3h=15

Last, you divide both sides by 3 giving you h=5, meaning the companies charge the same price after 5 hours.

A total of 729 students participate in a school pep rally event. If every 30 minutes, 2/3 of the students leave, after 2 hours,

trapecia [35]

There will be 9 students left at the prep rally after 2 hours.

After 30 minutes

Total Number of students = 729
2/3 of 729 = 486
Number of students left = 729 - 486 = 243

After 1 hour:

2/3 of 243 = 162
Number of students left = 243 - 162 = 81

After 1 hour 30 minutes :

2/3 of 81 = 54
Number of students left = 81 - 54 = 27

After 2 hours :

2/3 of 27 = 18
Number of students left = 27 - 18 = 9

Therefore, the Number of students left after 2 hours will be 9.

There are 32 female performers in a dance recital. The ratio of men to women is 3:8. How many men are in the dance recital?

shusha [124]

Male:female=3:8

if there are 8 women units and 3 men units,
since there are 32 women, each unit must equal 32/8 or 4
so to find the men, you just multiply the unit by the number of units

4 times 3=12

there are 12 men
