Answer:

C.

2.67 inches by 2.27 inches

Step-by-step explanation:

We can use ratios to solve

1 in        x inches

-------- = ---------

7.5 ft       20 ft

Using cross products

1*20 = 7.5x

Divide each side by 7.5

20/7.5 =7.5x/7.5

2.67 =x

We can do the same for the other dimension

1 in        x inches

-------- = ---------

7.5 ft       17 ft

Using cross products

1*17 = 7.5x

Divide each side by 7.5

17/7.5 =7.5x/7.5

2.27 =x

2.67 inches by 2.27 inches

natulia [17]

In this question, we're trying to find how much Paul will pay per month in premiums.

We know that the plan costs $7,710 for a year

In order to find his premium cost per month, we need to get the total price for the year and divide it by 12, since there are 12 months in a year.

Solve:

7,710 ÷ 12 = 642.5‬0

This means that he'll pay $642.5‬0 a month.

Maureen measured a house and its lot and made a scale drawing. The scale she used was
PIT_PIT [208]

The most appropriate choice for unitary method will be given by-

Length of driveway  in the drawing is 3 inch

What is unitary method?

Unitary method is the method in which value of a single unit can be calculated from the value of a multiple unit and value of a multiple unit can be calculated from the value of a single unit.

Sometimes value of single unit is less than value of multiple unit

For example - cost of food and quantity of food

Sometimes value of single unit is more than value of multiple unit

For example- Number of men and time taken by those men to do a work

Here,

Scale used by Maureen is 1 inch = 8ft

Actual length of house's driveway = 24 feet

8 ft of room is equal to 1 inch on scale

1 ft of room is equal to \frac{1}{8} inch on scale

24 feet of room is equal to \frac{1}{8} \times 24 inch on scale

24 feet of room is equal to 3 inch on scale

Length of driveway  in the drawing is 3 inch
