igomit [66]

Answer:

The tax on property assessed at $660,000 is  <u>$13860 </u>.

Step-by-step explanation:

Given:

In Atlanta the tax on a property assessed at $930,000 is $19,530.

The tax rates are proportional to this city.

Now, to find the tax on a property assessed at $660,000.

So, <em>we need to get the tax rate of Atlanta first.</em>

Tax Rate = Tax / Property assessed × 100.

Tax\ rate=\frac{19530}{930000} \times 100

Tax\ rate=0.021 \times 100

Tax\ rate=2.1\%

<em>According to question the</em><u><em> tax rates are proportional.</em></u>

<em>So, </em><u><em>for getting the tax in this city we use the same rate of Atlanta</em></u><em>:</em>

Tax = tax rate of property assessed.

Tax = 2.1\% of\ \$660,000

Tax = \frac{2.1}{100}\times 660000.

Tax = 0.021\times 660000

Tax=\$13860

Therefore, the tax on property assessed at $660,000 is $13860.

ICE Princess25 [194]

Step-by-step explanation:

a. 12 + 4 = 16

1st left equation is matched to 4th right value

b. 3(4) + 7 = 19

2nd left equation is correctly matched to 2nd right value

c. 4(7) - 10 = 18

3rd left equation is matched to 1st right value

d. 1 / 2 × xy

1 / 2 × (4 × 7)

= 28 ÷ 2

= 14

4th left equation is matched to 3rd right value
