Working together, melissa and jing can mow a lawn in 5 hours. it would take melissa 8 hours to do the job alone. what is the value of r, the part of the lawn that jing could complete in 1 hour? a. 0.075.
b. 0.125.
c. 0.375.
d. 0.625.

The amount of work completed by Jing in 1 hour is 0.075 which is option A

Step-by-step explanation:

Melissa & Jing can complete the work in 5 hours

This means that the amount of work completed by Melissa & Jing working together in 1 hour is (1÷5) = 0.2

Melissa will do the job in 8 hours, which means that the amount of job completed by Melissa working alone in 1 hour is (1÷8) = 0.125

The amount of work completed by Jing when he works alone in 1 hour will be the difference of amount of work completed by both of them in 1 hour with the amount completed by only Melissa in 1 hour.

There Amount of work completed by Jing in an hour = 0.2 - 0.125 = 0.075

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
