A rectangular room measures 15 feet by 18 feet. It is going to be carpeted with carpeting that sells for $38 per square foot.

dusya [7]

Answer:

a. 270 square feet

b. 3.75 inches by 4.5 inches

c. $10,260

Step-by-step explanation:

A rectangular room measures 15 feet by 18 feet. It is going to be carpeted with carpeting that sells for $38 per square foot.

a. What is the area of the room in square feet?

Area of a rectangular room = Length × Width

Length = 15 feet

Width = 18 feet

Area of the room = 15 feet × 18 feet

= 270 square feet

b. If the room is drawn to 1/4 inch represents 1 foot scale, give the dimension of the room in inches on the scale drawing. Please write in decimal form to the nearest hundredth.

From the above question:

1/4 inch = 1 foot

Length = 15 feet

Hence:

1 foot = 1/4 inch

15 feet = x inch

Cross Multiply

x = 15 × 1/4 inch

x = 3.75 inches

For the Width = 18 feet

Hence:

1 foot = 1/4 inch

18 feet = x inch

Cross Multiply

x = 18 × 1/4 inch

x = 4.5 inches

Therefore, the dimensions of the room in inches is

3.75 inches by 4.5 inches

c. What is the total price for the carpeting? _

From the above question, we know that: A square foot of carpet is sold for $38

The area of the room is 270 square feet

Hence:

1 ft² = $38

270 ft² = $x

Cross Multiply

1ft² × $x = 270 ft² × $38

$x = 270 ft² × $38/ 1 ft²

$x = $10,260

Therefore, the total price for the carpeting of the room is $10,260.

You can work at most 20 hours next week. You need to earn at least $90 to cover your weekly expenses. Your dog walking job pays

Vadim26 [7]

Answer:

The answer in the procedure

Step-by-step explanation:

Let

x ----> the dog walking hours

y ----> the car washing hours

we know that

The system of linear inequalities is equal to

$x+y\leq20$ -----> inequality A

$9x+10y\geq 90$ -----> inequality B

Solve the system of inequalities by graphing

The solution is the shaded area

see the attached figure

Two possible combinations of hours are

(10,10) and (0,9)

Verify

For (10,10)

Substitute the value of x and the value of y in both inequalities

Inequality A

$10+10\leq20$

$20\leq20$ -----> is true

Inequality B

$9(10)+10(10)\geq 90$

$190\geq 90$ ----> is true

therefore

(10,10) is a possible solution

For (0.9)

Substitute the value of x and the value of y in both inequalities

Inequality A

$0+9\leq20$

$9\leq20$ -----> is true

Inequality B

$9(0)+10(9)\geq 90$

$90\geq 90$ ----> is true

therefore

(0,9) is a possible solution
