What is the ratio of the area of the larger circle to the area of the smaller circle
krek1111 [17]

The formula of an area of a circle:

A=\pi r^2

We have R = 6mm and r = 5 mm.

Substitute:

A_1=\pi(6^2)=36\pi\ mmm^2\\\\A_2=\pi(5^2)=25\pi\ mm^2

The ratio:

\dfrac{A_1}{A_2}=\dfrac{36\pi}{25\pi}=\dfrac{36}{25}

Find the federal income tax of a married couple with two children, who have a combined income of $100,000.
Galina-37 [17]

Answer:

 $9,937.50

Step-by-step explanation:

Given

Total income of a married couple = $100,000

Number of children the couple has = 2

The taxable income of the family can be calculated by

Taxable income = total income - exemption deduction - standard deduction

We know that the exemption deduction for a married couple with two children as fixed by the U.S. government is $15,600.

And the standard deduction for a married couple with two children as fixed by the U.S. government is $12,200.

Thus the taxable income can be calculated by

Taxable income = total income - exemption deduction - standard deduction

                           = $100,000 - $15,600 -  $12,200

                           = $72,200.

So the taxable income is $72,200.

Now if the taxable income is in the range between

$17,850 to $72,500, the tax is $1,785 plus the marginal rate of 15% of the amount of $72,200 that is over $17,850.

Now in order to calculate tax ---

add $1,785 plus the marginal rate of 15% of the amount of $72,200 that is over $17,850.

Now deducting $17,850 from $72,200 will give $54,350.

So 15% of $54,350 is $8152.50

Therefore add $1,785 and $8,152.50 = $9,937.50

Therefore the tax payed by the couple is $9,937.50

WRONG!

24 x 10 x 90

(24 x 10) x 90

  240     x 90

That is NOT the same as 2400 x 90
