Answer:
Kirsten travels 7.5 miles to go to work.
Step-by-step explanation:
Bike: 10 MPH
Time: 1/4 Hour
1/4 of 10 = 2.5
Distance travelled on bike: 2.5 miles
Train: 20 MPH
Time: 1/4 Hour
1/4 of 20 = 5
Distance travelled by train: 5 miles
Add the distances together.
5 + 2.5 = 7.5
7.5 miles
Answer: does not make sense.
The statement " t<span>he beach ball we played with has a density of 10 grams per cubic centimeter" does not make sense.
Reasoning.
Inflated beach balls have a very low density, they are pretty much only air, plus the weight of the ball per se. Certainly that density is much lower than the density of water.
Inflated beach balls fall slowly in the air because their density is very close to the density of air and float on water because their density is less than the density of water.
Being the density of pure water 1 g/cm^3 you can predict, without any calculation, that the density of the beach ball is less than that and never 10 g/cm^3 which is 10 times the density of pure water.

So just find the factors of 90
90=2 times 3 times 3 times 5
so the factors could be
2,3,15
2,9,5
6,3,5
10,3,3
there are 4our
