meriva

Options

A. Caroline rents exactly 7 games each month.

B. Caroline rents exactly 6 games each month.

C. Caroline rents 6 or more games each month.

D. Caroline rents from 1 to 5 games each month.

Answer:

D. Caroline rents from 1 to 5 games each month.

Step-by-step explanation:

Given

Plan A:

C = 2n

Plan B:

C = n + 6

Required

Which options justifies A over B

The solution to this question is option (d).

In option d, n = 1,2,3,4,5

When any of the values of n is substituted in plan A and B, respectively; the cost of plan A is cheaper than plan B.

This is not so, for other options (A - C)

To show:

Substitute 1 for n in A and B

Plan A:

C = 2n  = 2 * 1 = 2

Plan B:

C = n + 6 = 1 + 6 = 7

Substitute 5 for n in A and B

Plan A:

C = 2n  = 2 * 5 = 10

Plan B:

C = n + 6 = 5 + 6 = 11

<em>See that A < B</em>

You can paint 75 square feet of a surface every 45 minutes

so

using proportion

Find out how long it takes you to paint a surface area of 42 square feet

\frac{75}{45}\ \frac{ft^2}{min}=\frac{42}{x}\ \frac{ft^2}{min}\\\\x=45(42)/75\\\\x=25.2\ min

What is the solution to the proportion 3/5=x/10
Savatey [412]
x is 6.

3 / 5 = 6 / 10

Where 10 / 5 = 2 then 2 * 3 = 6.

6 / 10 simplified by dividing both numerator and denominator by 2 will result to 3 / 5.
