Answer:
the answer is 30
Step-by-step explanation:
Let the number be x
- 3 (x - 12) = - 54
-3x + 36 = -54
-3x = -54 - 36
-3x = -90
x = -90/-3
x = 30
Answer:
x= 6 ± √31
Step-by-step explanation:
x^2-12x=-5
x^2 -12x +36= -5 +36
(x -6)^2= 31
√(x -6)^2= ±√31
(x-6)= ±√31
x= 6 ± √31
Answer:
233445.54 gallons
Step-by-step explanation:
Given data
Diameter= 15m
Radius= 7.5m
Height= 5m
Let us first find the volume
the volume of a cylinder is given as
V= πr^2h
substitute
V= 3.142*7.5^2*5
V= 3.142*56.25*5
V=883.6875 m^3
Hence the volume in gallons is
233445.54 gallons (from conversion tables)
