Answers

Answer 1

Answer:

11 am

Step-by-step explanation:

Bus A and Bus B leave the bus depot at 9 am.

Bus A takes 30 minutes to complete its route once

Bus B takes 40 minutes to complete its route once.

We solve this finding the Lowest Common Multiple of the minutes each bus uses to complete it's route

30 = 3 × 10

40 = 4 × 10

= 3 × 4 × 10

= 120 minutes

120 minutes after 9 am is

60 minutes = 1 hour

= 2 hours.

9am + 2 hours

= 11 am.

Therefore, they be back at the bus depot together at 11 am

Given the following information, choose the brand that is the better buy.Brand A: $1.25 for 10 ounces
Brand B: $1.47 for 12 ounces
Brand C: $1.68 for 14 ounces
Brand D: $1.84 for 16 ounces

By using proportions, it is found that the better buy would be d. Brand D: $1.84 for 16 ounces.

What is a proportion?

A proportion is defined as the fraction of a total amount.

In the given problem, the better buy will be given by the lowest ratio of price to ounces.

Hence:

1.25/10 = 0.125

1.47/12 = 0.1225

1.68/14 = 0.12

1.84/16 = 0.115

Hence brand D is the better buy.
