Answer:
The LCD in 1/30 + 1/24 is <u>90</u>.
The graph of y = -3x+5
Step 1: Since the y - intercept is 5, plot the point (0,5).
Step 2: Since the slope is -3, move 1 unit to the right and 3 units down, so plot the point (1,2).
Step 3: Connect those points by a straight line.
Answer:
X=-6
Step-by-step explanation:
The volume of the cylinder is equal to the sum of all spheres
the volume of 1 sphere is V1=4/3×pi×(1/2 x)³
simplified V1=1/6×pi×x²
we conclude that the volume of the cylinder is V2=270V1
V2=45×pi×x³
also the V2 can be calculated from the cylinder
V2= base(circle)×height
V2=(3x)²×pi×h=9x²×h
so we have
9x²×pi×h=45×pi×x³
simplified h=5x
