Answer:

A, B, C and F

Step-by-step explanation:

We have according to the options:

A. \sqrt{100} \times \sqrt{100}=10\times 10=20

B. 13.5+\sqrt{81} =13.5+9=22.5

C. \sqrt{9}+\sqrt{729}=3+27=30

D. \sqrt{64}+\sqrt{353}=8+\sqrt{353}, which is not rational.

E. \frac{1}{3}+\sqrt{216}=0.3+6\sqrt{6}, which is not rational.

F. \frac{3}{5}+2.5=0.6+2.5=3.1

Hence, the expressions representing rational numbers are A, B, C and F.

Merry Soy, married, earns a weekly salary of $830 and claims one withholding allowance. By the percentage method, how much incom
xxMikexx [17]
You need to find the amount subject to withholding, subtracting from the weekly salary the amount for one withholding allowance for weekly salaries, which is 77.90$:

830 - 77.90 = 752.1 $.

Then, look in the Fed Tax tables (
http://www.opers.ok.gov/Websites/opers/images/pdfs/2016-Fed-Tax-Tables.pdf ) for a married person with a weekly payroll.

You previously found an amount of  752.1 which is greater than 521 but less than 1613$: therefore the income tax to withhold is 35.70$ + 15% of excess over $521.

Therefore, calculate the income tax due: 35.70 + (752.1 - 521) × 15 ÷ 100 = 70.37$

The total amount of income tax that will be withheld is 70.37$
