Answer:
4.6 cubic feet
Step-by-step explanation:
take 34 1/2 gallons and divide it by 7 1/2 gallons
34.5 divided by 7.5 = 4.6
D = sqrt (x2 - x1)^2 + (y2 - y1)^2
(10,-8)...x1 = 10 and y1 = -8
(4,0)...x2 = 4 and y2 = 0
now sub and solve
d = sqrt (4 - 10)^2 + (0 -(-8)^2
d = sqrt (-6^2) + (8^2)
d = sqrt (36 + 64)
d = sqrt 100
d = 10 <==
The length of line segment EC is 35
Answer:
x = -7/9
Step-by-step explanation:
The usual recommendation is to clear fractions first. Here, you can do that by multiplying both sides of the equation by 6.
6(-1/2(3x -4) +3x) = 6(5/6)
-9x +12 +18x = 5 . . . . . . . . . simplify
9x = -7 . . . . . . . . . . . . . . . . . subtract 12
x = -7/9 . . . . . .divide by 9
__
Another way to do this is to eliminate parentheses first.
-3/2x +2 +3x = 5/6
3/2x = -7/6 . . . . . . . . . collect terms, subtract 2
x = (-7/6)(2/3) = -7/9 . . . . multiply by 2/3
Answer:
B. 100π
Step-by-step explanation:
The surface area of a sphere is given by
SA = 4 pi r^2
The radius is 5
SA = 4 * pi * r^2
SA = 4 * pi * 25
SA = 100 pi
