A scale drawing of Joshua's living room is shown below:
Nadya [2.5K]
To find the answer, first lets divide the width and length by the scale amount given, 2 cm.

Width: 4 cm / 2 cm = 2

Length: 6 cm / 2 cm = 3


After this, we multiply the result by the amount to scale up, in this case 4 feet.

Width: 2 * 4 = 8 feet


Length: 3 * 4 = 12 feet

Therefore the answer is the first option.

Find the radius of the sphere with the given volume. Show all work
yaroslaw [1]

Answer:

r = 15

Step-by-step explanation:

Volume of a sphere is given by

V = 4/3 pi r^3

4500 pi = 4/3 pi r^3

Divide each side by pi

4500 = 4/3  r^3

Multiply each side by 3/4

3/4 *4500  = 3/4 *4/3  r^3

3375 = r^3

Take the cube root of each side

(3375)^(1/3) = (r^3)^(1/3)

15 = r

Clara wants to cover the top of her jewelry box. The top of the box is a rectangle with a length of 9.4 cm and a width of 8.3 cm
Pavlova-9 [17]

Answer: 78.02 cm²


Step-by-step explanation:

1. To solve this problem you need to apply the formula for calculate the area of a rectangle, which is shown below:

A=l*w

Where A is the area of the rectangle, l is its lenght and  w is its width.

2. You know that the rectangle has a length of 9.4 cm and a width of 8.3 cm, therefore, you must substitute these values into the formula. Then, you obtain the following result:

A=(9.4cm)(8.3cm)\\A=78.02cm^{2}

What is the value of x in the equation 1.5(x + 4) – 3 = 4.5(x – 2)? 3 4 5 9
Arisa [49]

1.5(x + 4) - 3 = 3.5(x - 2)

We need to use the distributive property to simplify this.

1.5x + 6 - 3 = 3.5x - 7

<em><u>Subtract 1.5x from both sides</u></em>

6 - 3 = 2x - 7

<em><u>Simplify left side</u></em>

3 = 2x - 7

<em><u>Add 7 to both sides</u></em>

10 = 2x

<em><u>Divide both sides by 2</u></em>

x = 5
