How do you do the bottom portion of this? it’s my younger sister’s homework . i’m a sophomore and have no idea how to do it!

Hello!

Looking at how you set up the proportion, it is correct.

Although, the multiplication is incorrect.

You are supposed to multiply 68 by 25 which comes out to 1700. Then, you should divide it by 100 to get x = 17.

(divide both sides by 100)

Therefore, you should expect Sparky to catch it 17 times.

c. prove the lengths are the same.

step-by-step explanation:

you need to prove the segments are congruent. congruent segments have the same length. find the lengths of the segments using the distance formula, and compare them.

answer: c. prove the lengths are the same.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
