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.

The formula in getting the arithmetic sequence:
an = a1<span> + (n – 1)d.
</span>
We can substitute the values in order for us to know how many terms the sequence has.
an = 7373
a1 = 1313
d = 303
an = a1<span> + (n – 1)d
</span>7373 = 1313 + (n-1) 303
7373 = 1313 + 303n - 303
-303n = 1313 - 303 - 7373
303n = -1313 + 303 + 7373
303n = 6363
n = 21
So, there are 21 terms in the sequence given.
Answer:
I don't think so.
Step-by-step explanation:
1/2p-(1/4p-4)
1/2p-(1-16p/4p)
(2p-1+16p)/4p
(18p-1)/4p
2(9p-1)/4p
9p-1/2p
