One movie is 120 minutes long. Another is 100 minutes long. If both movies are started at 12 p. m., at what time will they start together again?

3:40 pm

Step-by-step explanation:

120 is 2 hours and 100 is 1 and 40 minutes

Given:

Time length of first movie = 120 min

time length of second movie = 100 min

start time = 12 pm

To find:

What time will they start together again

Steps:

for this question we have to find LCM of both of them,

120 = 2 * 2 * 2 * 3 * 5

100 = 2 * 2 * 5 * 5

LCM = 2 * 2 * 2 * 3 * 5 * 5

LCM = 4 * 2 * 3 * 5 * 5

LCM = 8 * 3 * 5 * 5

LCM = 24 * 5 * 5

LCM = 120 * 5

LCM = 600 min

600 min = 600/60 hr

              = 10 hours

Therefore, they will start again at 10 o'clock

Happy to help :)

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
