If one side of a triangle is 15 and another side is 20, then the third side
can be any length between 5 and 35. There are an infinite number of
possible triangles.

IF it happens to be a RIGHT triangle AND side 'a' and side 'b' happen
to be its legs, then the length of the third side is 25.  But you didn't
mention any of those details.

Billy is a professional baseball player. He had 99 singles, 47 doubles, 4 triples, and 15 home runs in his first year playing. I
Maurinko [17]

Answer: 792

Step-by-step explanation:

From what I got it should be 792 because it is asking for doubles, triples, and home runs all together at the same amount that he got on his first year.

It says after 12 years

Doubles 47 times 12 years = 564

Triples 4 times 12 years = 48

and

Home runs 15 times 12 years = 180

564 + 48 = 612

612 + 180 = 792

clara wants to run a total of 5 1/2 miles each lap around the track is 0.25 miles. how many laps around the track does clara nee
NemiM [27]

Answer:

22 laps

Step-by-step explanation:

Clara wants to run 5 1/2 miles, and the track is only 0.25 miles long. This is a fairly easy question, you just need to figure out how many times 5 1/2 goes into 0.25, because she wants to run that amount of miles (I could never run that much).

I hope that answers your question so you understand, and I hope you have a great rest of your day! :)
