Answer:
11v^2 - 8v + 1
Step-by-step explanation:
(4v^2 - 5v - 1) + (7v^2 - 3v + 2)
open brackets
4v^2 - 5v - 1 + 7v^2 - 3v + 2
place like terms together (remember signs remain same )
4v^2 + 7v^2 - 5v - 3v + 2 - 1
add or subtract like terms
11v^2 - 8v + 1
The answer to your question is 3 (9 + 5).
Because 3 × 9 is 27
And 3 × 5 is 15
Therefore your answer is 3 (9 + 5) :)
100 has 2 zeros so move your point from right to left 2 times that will give you teh answer of 823.21 Hope this helped
Answer:C) 36:1
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as πr^2h
Where
h represents the height of the cylinder.
r represents the radius of the cylinder.
π is a constant.
These two right circular cylinders have the same height, 45 centimeters.
The radius of the smaller cylinder is 22 centimeters and the radius of the larger cylinder is 6 times greater than that of the smaller cylinder. This means that the radius of the larger cylinder would be
6 × 22 = 132 centimeters
Volume of the larger cylinder would be
π × 132^2 × 45 = π × 17424 × 45
Volume of the smaller cylinder would be
π × 484× 45
the ratio of the volume of the larger cylinder to the volume of the smaller cylinder would be
(π × 17424 × 45) / (π × 484× 45)
= 36 : 1
