Question 1 of 17 Rachel rides her bicycle due east at 12 kilometers per hour. Amos rides his
bicycle due north at 16 kilometers per hour. If they left from the same point at
the same time, how far apart will they be after 3 hours?

they will be 60 kilometers apart.

Step-by-step explanation:

well you use pythagorean theorem

12 × 3

=36

16 × 3

=48

pythagorean theorem states that:

a²+b²=c²

so

48² + 36² =3600

then, because c is squared, you just square root it

√3600 = 60

I drew a diagram to help explain, it's a bit crude but it works

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
