I’m Atlanta, the tax on a property assessed at $930,000 is $19,530. If tax rates are proportional in this city, how much would t

igomit [66]

Answer:

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

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, we need to get the tax rate of Atlanta first.

Tax Rate = Tax / Property assessed × 100.

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

$Tax\ rate=0.021 \times 100$

$Tax\ rate=2.1\%$

According to question the tax rates are proportional.

So, for getting the tax in this city we use the same rate of Atlanta:

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.

During flu season there were 108 students at a squirrel on a particular day if there are 675 students in the school what percent

Oksi-84 [34.3K]

Answer:

16%

Step-by-step explanation:

Given the total number of students in a school = 675

Number of students at a squirrel during flu season = 108

Squirrels are known for transmitting flu disease, therefore if 108 students are at the squirrels during a particular day, there is possibility that this ones have contacted flu.

Percentage of those that have flu = number of students at the squirrels/Total number of students × 100%

= 108/675 × 100

= 10800/675

= 16%

This means that 16% of the students have flu

6. What are the zeroes for the function f(x) = 2x3 + 12x – 10x2?

agasfer [191]

Answer:

Step-by-step explanation:

f(x) = 2x^3 + 12x – 10x^2 can and should be rewritten in descending powers of x:

f(x) = 2x^3 – 10x^2 + 12x

This, in turn, can be factored into f(x) = x·(x² - 10x + 12).

Setting this last result = to 0 results in f(x) = x·(x² - 10x + 12).

Thus, x = 0 is one root. Two more roots come from x² - 10x + 12 = 0.

Let's "complete the square" to solve this equation.

Rewrite x² - 10x + 12 = 0 as x² - 10x + 12 = 0.

a) Identify the coefficient of the x term. It is -10.

b) take half of this result: -5

c) square this last result: (-5)² = 25.

d) Add this 25 to both sides of x² - 10x + 12 = 0:

x² - 10x + 25 + 12 = 0 + 25

e) rewrite x² - 10x + 25 as the square of a binomial:

(x - 5)² = 13

f) taking the sqrt of both sides: x - 5 = ±√13

g) write out the zeros: x = 5 + √13 and x = 5 - √13.

The three roots are x = 0, x = 5 + √13 and x = 5 - √13.
