• Machine s is cleaned every 12 weeks. •Machine that is cleaned every 8 weeks. What is the fewest number of weeks that will pass before both machines are cleaned again in the same week?

Answers

Week 24,assuming that both machines are cleaned at week 0, because multiples of 12 are 12, 24,36. And multiples of 8 are 8, 16, 24. 24 is also the LCM.

The gym teacher uses tape to mark a 4-square court on gym floor, as shown. The outerthe side lengths of 16 feet. What is the total length of tape the teacher uses to mark square A ?

Answers

32 16÷2=8×4=32 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

im assuming that square A and C are identical. therefore, they have the same sidelengths and since their sidelengths add to 16, each square must have sidelength 8. now the total length of tape used to mark square A is the perimeter of square A which is 8 + 8 + 8+ 8 = 32. we know each side is 8 cause it's a square and squares have equal sides of equal lengths.

A construction crew has just built a new road. They built the road at a rate of 7 kilometers per week. They built 8.75 kilometers of road. How many weeks did it take them?

Answers

7 kilometers per 1 week equals 8.75 kilometers per x weeks.

7 / 1 = 8.75 / x

7 = 8.75 / x

7x = 8.75

x = 8.75 / 7

x = 1.25

It took 1.25 weeks to build 8.75 kilometers of road.

Final answer:

The construction crew would need approximately 1.25 weeks to build 8.75 kilometers of road. This is calculated by dividing the total distance by the rate of construction.

Explanation:

To find out how many weeks it took the construction crew to build 8.75 kilometers of road, we need to divide the total distance (8.75 km) by the rate at which they built the road (7 km per week). So, the calculation will be 8.75 km ÷ 7 km/week.

This is a simple division problem. Using a calculator, you will find that 8.75 ÷ 7 equals approximately 1.25.

Therefore, the construction crew would need about 1.25 weeks to build 8.75 kilometers of road. Please note, this is an approximation, and actual times may vary.
