Freddy earns $750.00/week, he is single and has 3 dependents. He lives in a state with a tax rate of 3%. What does he pay in state income taxes every week?

Answers

Answer:

$17.88

Step-by-step explanation:

Freddy earns = $750 per week

Has 3 dependents

and he is single

Tax rate = 3%

Lets calculate Freddy's Annual Taxes and Taxable income

Freddy's Annual income = 750 *52 = $39,000

Annual Allowance for a single person = $2000

Annual allowance for 3 dependents = $2000 * 3 = $6000

Hence Freddy's Annual Taxable Income = ( 39000 - 8000 ) = $31,000

Annual withheld tax = 3% * $31,000 = $930

Therefore Freddy's weekly withheld tax = 930 / 52 = $17.88

Evaluate ba+cd if a=7/8 , b=−7/16 , c=0.8 , and d=1/4 . Write your answer as a mixed number in simplest form.

Answers

Answer:

-117/640

Step-by-step explanation:

ba + cd

b= -7/16

a= 7/8

c= 08.(4/5)

d= 1/4

Hence it can be calculated as follows

-7/16×7/8 + 4/5×1/4

-49/128 + 1/5

-246+128/640

= -117/640

Answer: -2 11/20

What is the approximate diameter of a tire that will make 775 complete rotations in one mile? (Note: there are 5280 feet
in 1 mile)

Answers

Answer:

About 2.17 feet.

Step-by-step explanation:

Let d represent the diameter of the tire.

Then the circumference of the tire will be:

[tex]C=d\pi[/tex]

So, the tire will travel dπ miles after one rotation.

After 775 rotations, the total miles traveled should be 5280 feet. Thus:

[tex]775(d\pi)=5280[/tex]

Solve for d:

[tex]\displaystyle d=\frac{5280}{775\pi}[/tex]

Approximate:

[tex]d=2.1686...\approx2.17[/tex]

The circumference of the tire should be about 2.17 feet.

lengths of right triangles.

If consider the Pythagorean Theorem and its converse. A, C, D, and E are correct statements.

What is Pythagoras's theorem?

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

In this case, statement A is correct because 6, 8, and 10 are possible side lengths for a right triangle.

Statement B is incorrect because 10, 15, and 20 are not possible side lengths for a right triangle.

Statement C is correct because the Pythagorean Theorem works only for sides of a right triangle.

Statement D is correct because if the sides of a right triangle are of lengths 8 and 15, its hypotenuse is 17.

Statement E is correct because the converse of the Pythagorean Theorem allows us to calculate the side lengths of right triangles.

Thus, the correct statements would be options A, C, D, and E.
