635/72=-5/2(-11/4+x)
distribute
635/72 = -5/2 * -11/4 - 5/2x
635/72 = 55/8 -5/2 x
multiply each side by 72 to clear the fractions
72*635/72 = 72*(55/8 - 5/2 x)
distribute
635 = 72* 55/8 - 72* 5/2 x
635 = 495 - 180x
subtract 495 from each side
140 = -180 x
divide by -180
-140/180 = x
-14/18 =x
-7/9 =x
Answer:
A sample of the data for the for the total income are as follows;
State, Indiana
Income, Number of families
0, 1
5, 1
10, 1
15, 1
20, 3
25. 4
From the data, we have;
The total income for the families from Indiana = $2,260
The total income for the families from New Jersey = $2,565
The average income for the families from Indiana ≈ $64.57
The average income for the families from New Jersey ≈ $73.29
The median income for the families from Indiana = 0
The median income for the families from New Jersey = $55
The first quartile for the families from Indiana = $0
The first quartile for the families from New Jersey = $0
The third quartile for the families from Indiana = $85
The third quartile for the families from New Jersey = $120
Step-by-step explanation:
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
