Consider the Pythagorean Theorem and its converse. Which statements are correct?
A)
6, 8, and 10 are possible side lengths for a right triangle.
B)
10, 15, and 20 are possible side lengths for a right triangle.
The Pythagorean Theorem works only for sides of a right triangle.
D)
If the sides of a right triangle are of length 8 and 15. its hypotenuse is 17
E)
The Converse of the Pythagorean Theorem allows us to calculate side
lengths of right triangles.
Answer:
Step-by-step explanation:
A-Yes
B-No
C-Yes
D-Yes
E-Yes
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.

Ahmed invests $1,500 at an interest rate of 4%, compounded quarterly and another $1,500 at an interest rate of 3.75%, compounded annually. How much are the investments worth in total at the end of 6 years?
Answer: $1904.60
Step-by-step explanation:
This is 1500(1+.04/4)^24 where .04/4 is the interest rate for each compounding, or the interest rate /4, for 4 quarters.
The 24 is 4 quarters/year * 6 years
round at the end
=$1904.60

2^5*2^negative 3 simplify
Answer:
4
Step-by-step explanation:
Simplify the following:
2^5/2^3
Hint: | For all exponents, a^n/a^m = a^(n - m). Apply this to 2^5/2^3.
Combine powers. 2^5/2^3 = 2^(5 - 3):
2^(5 - 3)
Hint: | Subtract 3 from 5.
5 - 3 = 2:
2^2
Hint: | Evaluate 2^2.

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?
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

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)
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.
