The circumference of a circle is C = 7.64(pi) inches. what is the length of the radius and diameter.

Answers

The exact circumference is shown there.  The exact circumference has the length of the diameter and pi.  Like,  say a diameter was 8 inches.  It would be 8(pi).

The diameter here is 7.64 inches.  A radius is half as big as a diameter,  so divide the diameter by 2.  The radius is 3.82 inches.

Hope this helps!

7. Factor the expression.
42 - 64

Answers

Answer:

-22 = -2^1×11^1

Step-by-step explanation:

Factor the following integer:

-22

Hint: | Is 22 divisible by 2?

The last digit of 22 is 2, which means it is even. Therefore 22 is divisible by 2:

22 = 2 11:

-22 = -2×11

Hint: | Now try to factor 11. Is 11 divisible by 2?

11 is not divisible by 2 since 11 is odd and 2 is even:

-22 = -2×11 (11 is not divisible by 2)

Hint: | Is 11 divisible by 3?

The sum of the digits of 11 is 1 + 1 = 2, which is not divisible by 3. This means 11 is not divisible by 3:

-22 = -2×11 (11 is not divisible by 2 or 3)

Hint: | Is 11 divisible by 5?

The last digit of 11 is not 5 or 0, which means 11 is not divisible by 5:

-22 = -2×11 (11 is not divisible by 2, 3 or 5)

Hint: | Is 11 divisible by 7?

Divide 7 into 11:

| | 1 | (quotient)

7 | 1 | 1 |  

- | | 7 |  

| | 4 | (remainder)

11 is not divisible by 7:

-22 = -2×11 (11 is not divisible by 2, 3, 5 or 7)

Hint: | Is 11 prime?

No primes less than 11 divide into it. Therefore 11 is prime:

-22 = -2×11

Hint: | Express -22 as a product of prime powers.

There is 1 copy of 2 and 1 copy of 11 in the product:

Answer: -22 = -2^1×11^1

The formula for the volume of a pyramid is V=1/3Bh. Which of the following equations is equivalent to the given formula?A) B=3V/h

B) B=3h/V

C) B=V-1/3/h

D) B=V+1/3/h

Answers

Answer:

A) B = 3V/h

Step-by-step explanation:

Given: The formula for the volume of a pyramid is V=1/3Bh.

From the above equation, we have to solve for B.

We use inverse operation to find B.

Multiply by reciprocal of 1/3 on both sides. the reciprocal of 1/3 is 3.

So, multiply by 3 on both sides, we get

3V = 3*1/3*B*h

3V = B*h

Now divide both sides by h, we get

3V/h = Bh/h

3V/h = B

Therefore, the answer is A) B = 3V/h

A) B=3V/h

Multiply both sides by 3 to get 3V=Bh. Divide both sides by h, and you get 3V/h=B

In a right isosceles triangle, the lengths of both legs are equal. For the given iscoceles triangle, what is the value of x? (The given triangle has a hypotenuse of square root sign with 72 under it. The two legs both have x.)

Answers

it will just be 72 because both of those legs of an isosceles triangle are congruent which means that they're both X & X which is the same value
