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.
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
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:
Where 
is the area of the rectangle, 
is its lenght and 
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:
Answer:
$49.70
Step-by-step explanation:
6.10x5+4.80x4=$49.70!
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
