The ratio is 4 to 5 what mean 4 boys to 5 girls
so than there are 12 boys what is 3*4 than just multiplie 3*5 and will get 15 girls like result
so than there are in the class 12 boys so will be in the class 15 girls sure
hope helped
Ok, so we do pythagoran theorm so
assume that jason is to the left or right of the anchor
ok
the boat anchor is 172.22 feet so 20 feet above that is 152.22 feet
then the other leg or distance to jeff is 188.82
a²+b²=c²
152.22²+188.82²=c²
23170.9284+35652.9924=c²
58823.9208=c²
sqrt both sides
242.53643190251=c
the distance is about 242.5ft
For this case we have the following equation:
Q = Av
Where the area is given by:
A = pi * r ^ 2
A = pi * (d / 2) ^ 2
A = (pi / 4) * d ^ 2
Substituting we have:
Q = ((pi / 4) * d ^ 2) v
From here, we clear the diameter:
d = root ((4 / pi) * (Q / v))
Substituting values we have:
d = root ((4 / pi) * (50/600))
d = 0.36 feet
Answer:
The diameter of a pipe that allows a maximum flow of 50ft ^ 3 / min of water flowing at a velocity of 600ft / min is:
d = 0.36 feet
