In multiplying fractions, you multiply the numerators and denominators.
51 / 2 * 21 / 3
can be reduced as

(17 / 2) * (21 / 1)
357 / 2 --> This is the answer based on the given.

Assume that its a mixed fraction:
5 1/2 * 2 1/3
11/2 * 7/3
= 77 /6

You are paid $7.25/hour. You work 40 hours/week for 2 weeks. Your involuntary deductions are FICA (7.65%), federal withholding (
Vedmedyk [2.9K]

Answer:

$413.83

Step-by-step explanation:

Your earnings for the two weeks are

7.25(40)(2) = 580

The deductions for FICA will be

0.0765(580) = 44.37

The deductions for federal withholding will be

0.14(580) = 81.2

The deductions for state withholding will be

0.07(580) = 40.6

This makes your realized income

580-(44.37+81.2+40.6) = 580-166.17 = 413.83

What is 2.16 repeated as a decimal
Zarrin [17]
Ok, so what we want to do here is first remove the repeating decimal.

x=2.16 repeating
10x=21.6 repeating
100x=216.6 repeating

Subtract 10x=21.6 repeating from 100x=216.6 repeating. This will get rid of the repeating numbers.

100x=216.6 repeating
-10x=21.6 repeating
__________________
90x=195

Divide both sides by 90.

x=195/90

Now you can simplify that into 13/6.

12. Find the area lying above the x - axis and below the parabolic curve y = 4x - x2.
Margarita [4]
First we find the zeroes so we don't take the integral of negative bits

4x-x²
x(4-x)
zeroes at x=0 and x=4
it opens down
so the part we are interested in is the bit between x=0 and x=4

\int\limits^4_0 {4x-x^2} \, dx =[2x^2- \frac{1}{3}x^3]^4_0=(32- \frac{64}{3})-(0)=  10.6666666666 or aout 10 and 2/3
