Answer:
B) x = 8
; y = 4
Step-by-step explanation:
in a 30-60-90° triangle the sides, respectively, are in the ratio of
1 : : 2
we can find 'x' by creating this proportion:
12/ = x/2
cross-multiply to get:
x = 24
x = 24/
we can simplify this by 'rationalizing the denominator' which is to
multiply numerator and denominator by to get:
(24)÷3, which is 8
we know that side 'y' is half that of side 'x'
therefore y = 4
= 45x + 52y -5x + 40y
= 45x - 5x + 52y + 40y
= 40x + 92y
the answer is B
Answer:
The area of the base is 14.5π in²
Step-by-step explanation:
The volume of a cylinder is given by
Volume =base\:area \times height
Or
V=Bh
It was given that the volume of the cylinder is 174π in³.
The height was given as 12 inches.
We substitute to get,
174π=12B
Divide both sides by 12 to get:
B=14.5π in²
Hence the area of the base is 14.5π in²
