Two buses use the stop at meadowland road and mockingbird lane. bus 143 stops every 30 minutes on its express route to downtown. bus 62 stops there every 8 minutes on its west side route. if they were both at the stop at 6: 30 am, when will they arrive together again?

8:30 AM

Step-by-step explanation:

Given:

Bus 143 stops every 30 minutes on its express route to downtown

and  Bus 62 stops there every 8 minutes on its west side route

both meet at the bus stop at 6.30 AM

to find when they would meet the second time we need to find LCM( 30,8)

= 120

Hence the two buses would meet after 120 minutes that is 2 hours.

Hence they would be meet at 6.30+2= 8.30 AM

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

a is the right answer
