A landscaper estimates that a set of plants can be installed in 6 hours by 12 workers. The landscaper wants to finish a set of plants in 4 hours. Assuming that the variables are inversely related, how many workers should the landscaper bring to the job?

A: 8
B: 10
C: 14
D: 18

option d is the correct answer.

Step-by-step explanation:

The landscaper estimates that a set of plants can be installed in 6 hours by 12 workers.

Let h represent the number of hours and let w represent the number of workers. Assuming that the variables are inversely related, introducing a constant of variation, k, the expression becomes

h = k/w

Substituting h = 6 and w = 12 into the expression, it becomes

6 = k/12

k = 12 × 6 = 72

The expression becomes

h = 72/w

If the landscaper wants to finish a set of plants in 4 hours, the number of workers that he needs to bring to the job would be

4 = 72/w

w = 72/4 = 18

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
