2. (0, 0)

3. 1/3

1. This is a reduction becuase the image gets smaller.

2. The point of dilation is the origin because that is what they both share and it is where is shrinks with. Sorry if that sounded really weird it is how I like to think about it.

3. The scale factor is 1/3 because the size shrinks 3 times.

A box in the shape of a cube has a volume of 64 cube inches. What is the length of a side of the box

Naily [24]

The volume of a cube can be expressed as

Let V = volume

Let a = side length

V = a^3

We need to solve the formula to isolate the variable a. First, we must cube root each side.

∛(V) = a. With our new formula, we plug in 64 cube inches into V.

∛(64) = a.

4 = a.

The length of one side on our cube is 4 inches.

A 16 1/2 kilometer stretch of road needs repairs. Workers can repair 2 1/4 kilometer of road per week. How many weeks will take

liraira [26]

Answer:

$7\frac{1}{3}\ weeks$

Step-by-step explanation:

we know that

To find out how many weeks it will take to repair this stretch of road, divide the total length of the road by the workers' rate

$\frac{16\frac{1}{2}}{2\frac{1}{4}}$

Convert mixed number to an improper fraction

$16\frac{1}{2}\ km=\frac{16*2+1}{2}=\frac{33}{2}\ km$

$2\frac{1}{4}\ km=\frac{2*4+1}{4}=\frac{9}{4}\ km/week$

substitute

$(33/2)/(9/4)=\frac{132}{18}\ weeks$

Convert to mixed number

$\frac{132}{18}\ weeks=\frac{126}{18}+\frac{6}{18}=7\frac{1}{3}\ weeks$
