8 0

Answer:

14 days

Step-by-step explanation:

Total Problems = 175

Finished Problems = 8

Remaining = 175 - 8 = 167

8 problems in 30 minutes, means:

30/8 = 15/4 = 3.75 minutes per problem

If he works for 45 minutes, at that rate, he can solve:

45/3.75 = 12 problems per day

To finish 167 problems, he will need:

167/12 = 13.91

Rounded, that is 14 days more to finish

On the function machine shown below, the function rule is given as a variable expression. When the output is 99, what is the inp

beks73 [17]

Answer: option d.

Step-by-step explanation:

We have the function:

y = f(x) = x^2 - 1

The output is 99 when y = 99, and the input is x.

Then we need to solve:

y = 99 = x^2 - 1

for x.

99 = x^2 - 1

99 + 1 =x^2

100 = x^2

√100 = x

10 = x

The correct option is d, input equals 10.
