If the radius of mars is about 13.7% of neptune's radius, what is the radius of neptune?

Gnesinka [82]3 years ago

You said that                                 M is 13.7% of N

In algebraic notation                    M  =  0.137 N

Divide each side by  0.137 :      N  =  M / 0.137  =  7.3 M (rounded)

Online or in a real book, you can look up the radius of Mars.
Then write it in place of 'M' in this solution, and you'll have
an actual number for the radius of Neptune.

Zoe had 3 1 /8 feet of orange ribbon. She used some ribbon to make a bow for a gift now she has 1 3 /8 feet of orange ribbon lef
Nastasia [14]

Answer:

Orange ribbon Zoe use is  1\frac{3}{4} \ feet.

Step-by-step explanation:

Given:

Zoe had 3 1 /8 feet of orange ribbon. She used some ribbon to make a bow for a gift now she has 1 3 /8 feet of orange ribbon left.

Now, to find the orange ribbon Zoe use.

Let the orange ribbon Zoe use be x.

Total orange ribbon Zoe had = 3\frac{1}{8} = \frac{25}{8} \ feet.

Ribbon Zoe had left = 1\frac{3}{8} =\frac{11}{8} \ feet.

Now, to get the orange ribbon Zoe use:

\frac{25}{8} -x=\frac{11}{8}

<em>Subtracting both sides by </em>\frac{11}{8}<em> we get:</em>

\frac{25}{8} -x-\frac{11}{8} =0

<em>Adding both sides by </em>x<em> we get:</em>

\frac{25}{8} -\frac{11}{8} =x

\frac{25-11}{8} =x

\frac{14}{8}=x

x=\frac{14}{8}

x=\frac{7}{4}

x=1\frac{3}{4}\ feet.

Therefore, orange ribbon Zoe use is 1\frac{3}{4} \ feet.

Pre image ABCD was dilated to be image A’B’C’D, where the center of dilation is the origin. What scale factor was used in the di
ArbitrLikvidat [17]

Answer:

The scale factor is 0.25

Step-by-step explanation:

we know that

The dilation is a non-rigid transformation that produce similar figures

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem

ABCD and A'B'C'D' are similar

therefore

\frac{A'B'}{AB}=\frac{B'C'}{BC}=\frac{C'D'}{CD}=\frac{A'D'}{AD}

Find the scale factor

Looking at the graph

we have

A'B'=1\ unit\\AB=4\ units

Let

z ---> the scale factor

z=\frac{A'B'}{AB}

substitute the values

z=\frac{1'}{4}=0.25
