Answer 1
Answer: JKL is similar to PQR

so they want PR 

JKL is similar to PQR

So PR is similar to JL

And they also give us the sides KL and QR

JKL is similar to PQR

Both of those sides are similar, so we can form a proportion.

\sf { (PR)/(JL) = (QR)/(KL) }

Plug in the numbers:

\sf { (PR)/(6) = (15)/(9) }

Cross multiply:

\sf{ PR * 9 = 6 * 15}

Isolate PR

\sf{ PR = (6 * 15)/(9)}

Simplify it

\sf{ PR = 10}

So your final answer is

\boxed{\bf{10 centimeters}}
Answer 2
Answer: I can only see the similar triangle problem, with sides 6cm, 9cm, and 15cm. Since the triangles are similar, the ratio for side lengths is the same. 6:9 simplifies to 2:3. If we try to solve ?:15 we get 10 as 10:15 is equivalent to 2:3, so the length is 10 cm

Can 31/50 be simplified

Answers

no because when  one number is odd and the other one is even it can't be simplified (unless they are multiples/factors of each other) ex: 7/14
No, 31, a prime number, can not be divided any more to become another numerator, not to mention having to correspond with 50 as well.

A triangular pyramid has the same base and height as a triangular prism. The volume of the pyramid is 26 cubic centimeters. What is the volume of the triangular prism?

Answers

The formula for the volume of a triangular pyramid is:

V=1/3AH (where A=area of the base and H=height)

The formula for the volume of a triangular prism is:

V=AH (where A=area of the base and H=Height)

Since the base and the height are the same in this problem for both the prism and the pyramid, solving for the volume of the prism is simple.

Looking at the formulas, you'll see that the volume of the pyramid (assuming that both the height and the area of the base are the same) is 1/3 the volume of the prism.

V(pyramid)=1/3V(prism)

Now lets input the volume of the pyramid

26cm³=1/3 V(prism)
Divide both sides by 1/3
78cm³=V(prism)

Answer=78cm³
