Answer:
The height of the second cone is 2 <em>h</em>₁.
Step-by-step explanation:
The volume of a cone is:

The volume of the first cone is, <em>V</em>₁ = 5 in³.
The volume of the second cone is, <em>V</em>₂ = 10 in³.
The two cones have the same base diameters.
This implies that the two radii are same, i.e. <em>r</em>₁ = <em>r</em>₂.
Compute the height of the second cone as follows:





Thus, the height of the second cone is 2 <em>h</em>₁.
To factor the trinomial, you can use the ac method where you multiply the first and last terms together (6 and 9) and add up to 15.
In this case ac= 54
2 numbers that multiply to 54 and add up to 15 would be 6 and 9 so place these numbers where the 15 would be:

Then group terms to simplify:

Simplify any like terms:

And group together again:

You can simplify a 3 out of the first expression one more time to get:

Which would be the factored form. I hope this helps :)
Answer:
1
Step-by-step explanation:
500 (non smokers)÷ 25(random students out of the group)= 20 inches.
20 inches ÷ 74 inches= 3.70
X=-2y+3
