Answer:

It could be 2:5 or 6pi:15pi

Step-by-step explanation:

If you write the ratio of the surface area as a fraction, you would get $\frac{20\pi *yd^{2} }{125\pi *yd^{2} }$ . Simplifying it would leave $\frac{4}{25}$ . But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is $\frac{2}{5}$ . The answers would be 2:5 and 6pi:15pi.

<h2>○=> <u>Correct option</u> :</h2>

$\color{plum} \bold{ \tt \: \bold{C. \$20,652.00}}$

<h3>○=> <u>Steps to derive correct option</u> :</h3>

Selling price of a car = $19,000

Percentage of sales tax in the city = 8.3%

Sales tax :

$= \tt \frac{8.3}{10 \times 100} \times 1900$

$= \tt \frac{8.3 \times 19000}{1000}$

$= \tt \frac{1577000}{1000}$

$\color{plum} = \tt \$1577$

Thus, the sales tax on the car = $1577

Cost of license and title = $75

Total price of car :

= Cost price of car + Sales tax + cost of license/title

$= \tt19000 + 1577 + 75$

$\color{plum} = \tt \$20652$

Thus, the total purchase price of the car = $20,652.00

Therefore, the correct option is <em>(C) $20,652.00</em>

What is the answer to this problem

lyudmila [28]

When two pentagons are congruent, then the corresponding angles and sides are equal (congruent).

As, Pentagon $GDXLP\cong$ Pentagon $ARKMV$

Being congruent, the corresponding sides are equal(congruent).

So, $\overline{GD} \cong \overline{AR}$ , $\overline{DX} \cong \overline{RK}$ , $\overline{XL} \cong \overline{KM}$ , $\overline{LP} \cong \overline{MV}$ , $\overline{GP} \cong \overline{AV}$ , $\overline{GL} \cong \overline{AM}$ , $\overline{DL} \cong \overline{RM}$ , $\overline{DP} \cong \overline{RV}$ and $\overline{XP} \cong \overline{KV}$
