Answer: Paul will be 30 years old

Step-by-step explanation:Let the age of her sister be x, then from the given data

=> 4x = 20

=> x = 5 years

The age of her sister is 5 years

In the second case, paul is twice as old as his sister

=> Age of paul = 2(x)

=> Age of paul = 10 years

Paul will be 10 years old when he is twice as old as his sister

Answer:

Paul will be 30 years old.

Step-by-step explanation:

Paul's sister's age is 1/4 of 20. 20 * 1/4 = 5 years.

Age difference between the siblings : 20 - 5 = 15 years.

That means that Paul will still be 15 years older when he'll be twice the age of his sister.

15 * 2 = 30 years.

What is the length of the hypotenuse
nika2105 [10]

<u>Given</u>:

Given that the length of the two legs of the right triangle are 28 m and 45 m.

We need to determine the length of the hypotenuse.

<u>Length of the hypotenuse:</u>

The length of the hypotenuse can be determined using the Pythagorean theorem.

Thus, we have;

hyp^2=28^2+45^2

Simplifying, we get;

hyp^2=784+2025

hyp^2=2809

Taking square root on both sides, we get;

hyp=\sqrt{2809}

hyp=53 \ m

Thus, the length of the hypotenuse is 53 m

Hence, Option C is the correct answer.

How in the world do I do this can somebody help please.
ValentinkaMS [17]

Answer:

Bl^2+4Bl*Fh

Step-by-step explanation:

I'm not quite certain what "draw a net" means here. But for part b, we are doing the formula. The bottom part is a square(assumingly so take this with a grain of salt), thus making the base equal to 3*3 cm or 9 cm^2. The triangular faces are each 3*2.24 cm or 6.72 cm^2. We then multiply this by 4 to get 26.88. Thus, the equation is Bl^2(Base length squared)+Bl*Fh(Face height, I forgot the official name sorry about that)*4 for part b.
