Answer:
30 miles
Step-by-step explanation:
Let d represent the distance to the island. The relation between time, speed, and distance is ...
time = distance/speed
so the total time for the round trip is ...
d/15 +d/10 = 5
Multiplying by 30, we get
2d +3d = 150
d = 150/5 = 30
The island was 30 miles from the harbor.
Factor m^2-5m-14
(m-7) (m+2)
acute scalene
acute because all angles below 90 degrees, scalene because no sides are the same length
z^3
Z cubed is Z X Z X Z = Z^3
.75 * p = 15
divide by .75
p = 15/.75 = 20
20 peaches
.15 * d = puppies
.15 * 60 = puppies
puppies = 9
stereo *.09 = 35
divide by .09
stereo = 35/.09
stereo = 388.89
