The extended warranty on a garage door is $238. If the warranty costs 35% of the purchase price, how much does the garage door i

-BARSIC- [3]

Answer:

d. $680.

Step-by-step explanation:

Let x be the cost of garage door.

We have been given that the extended warranty on a garage door is $238 and the warranty costs 35% of the purchase price. This means 35% of x equals 238.

We can represent this information in an equation as:

$\frac{35}{100}x=238$

$0.35x=238$

$x=\frac{238}{0.35}$

$x=680$

Therefore, the cost of garage is $680 and option d is the correct choice.

Answer:

4. 17

5. 28

Step-by-step explanation:

4. This shape can be broken up into a square and two identical triangles.

The area of a square is A=S*S

The side length of the square is 3

So the area of the square is:

A = 3 * 3

A = 9

The area of the triangle is A=(1/2)B*H

The height is 4 and the base is 2

So the area of the triangle is:

A =(1/2) * 2 * 4

A= 4

To get the total area we add the values. Since there are two triangles, we will add the triangle area twice.

So the total area is

A = 9 + 4 + 4

A = 17

The area is 17.

5. We can split the shape into two triangles and calculate the area like that.

Remember the area of a rectangle is

A = L*W

Area of the first triangle is

A = 4 * 5

A = 20

The area of the second triangle is

A = 4 * 2

A = 8

So the total area is 28

I dont feel like doing the rest of the problems, but the process is similar.

The length of a rectangle is 3cm more than twice the width. The perimeter is 84 cm. Find the dimensions .

blsea [12.9K]

Width of the rectangle is 13 cm and length is 29 cm.

<u>Step-by-step explanation:</u>

Step 1:

Given perimeter of the rectangle = 84 cm. Let the width be x, then the length of the rectangle = 2x + 3. Use the formula for perimeter of a rectangle = 2(length + width) to find the dimensions.

84 = 2(2x + 3 + x) = 2(3x + 3) = 6(x + 1) [taking 3 as common factor outside)

⇒ 84 = 6x + 6

⇒ 78 = 6x

∴ x = 13

⇒ Width of the rectangle = 13 cm

∴ Length of the rectangle = 2x + 3 = 29 cm
