7 0

Answer:

C

Step-by-step explanation:

18's factors are 2 * 3 * 3

The two 3s can reduce the result further. sqrt (2 * 3 * 3)

square root 18 = 3*sqrt(2)

There are two sides with this length. Their total is 3sqrt(2) + 3sqrt(2) = 6√2

The perimeter is the sum of all three sides = 6 + 6√2

A boat that sold for $12,500 had a sales tax of $562.50. How much is the tax on a boat that sells for $9,550?
Degger [83]

Answer:

$429.75

Step-by-step explanation:

First, find the tax rate on the sale of the boat:  Let r represent that rate.  Then,

$12,500r = $562.50.  Solving for r, we get r = $562.50 / $12,500 = 0.045

The tax rate is 0.045, or 4.5%.

Applying this tax rate to a boat selling for $9,550:

0.045($9,550) = $429.75.  This is the amount of tax on the 2nd boat.
