I'm guessing that the 2 in that is ^2? if so, it opens down.

The property taxes on a business were $1035. What was the tax rate of the business office was valued at $115,000?
olya-2409 [2.1K]

Answer:

The rate of tax is 0.9% of the actual business amount.

Step-by-step explanation:

Given that:

Tax amount = $1035

Business value = $115,000

So, for finding the rate, we will have to divide the tax amount by business value and multiply it by 100 as follows:

Rate = 1035/115,000 * 100

By simplifying we get:

Rate = 0.009 *100

Rate = 0.9 %

This means that the tax rate is 0.9% of the original amount.

i hope it will help you!

(1,5) (2,7)<br> How to find the equation of the line passing through the given points
IceJOKER [234]

Answer:

y = 2x - 3

Step-by-step explanation:

to do this problem, we will use the following formula to find the slope of the line

(y2 - y1) / (x2 - x1)

(1,5) (2,7)

(7 - 5) / (2 - 1)

2 / 1

2 = m

next, we will substitute the slope and one of the points into the slope-intercept form (y = mx + b) and solve for b to find the y-intercept

y = mx + b

7 = (5)(2) + b

7 = 10 + b

-3 = b

finally, we put it all together into one equation

y = 2x - 3

Arati posted a comment on her blog. Each day the number of responses to her comment was 125% of the number she received on the p
zvonat [6]

If the next number is 125% of the previous number, that means that the previous number is increasing by 25% each time.

The multiplier for increasing by 25% is:

(100 + 25) ÷ 100 = 1.25

So on day one, there are 64 responses. That means on day two, there will be:

---> 64 x 1.25 = 80 responses

On day 3, there will be:

---> 80 x 1.25 = 100 responses

Finally, on <u>day 4</u>, there will be:

---> 100 x 1.25 = 125 responses

A quicker way of getting this would be to do:

64 x 1.25³      since you are multiplying by 1.25  3 times

125 responses
