Answer:343cm^3

Step-by-step explanation: looking at the question given by finding the

Volume of a cube=l^3

The Length =7cm

Then we are going to have;

V=7cmx7cmx7cm

Therefore, our answer will now be

V=343cm^3

Lets write formulas for volume of both cone and can

Cone:
Vc = Bc*Hc/3

Can:
V = B*H

where B is basis and H is height for each

Now because cone fits perfectly inside can that means that both B and H are the same
from this we can see that cone has 3 times less volume than a can that cone is inside of.

if can has 36 volume that means that cone has:
36/3 = 12 volume

Answer is 12.

Change x + 2y = 6 into slope-intercept form.
mart [117]

Answer:

The slope intercept form involves solving for y, such that the equation looks like this: y = mx + b, where m is a constant representing the slope of the line, and b is a constant representing the value of the y-intercept.

Starting with the equation x+2y=6 and subtracting x from both sides gives 2y =  -x + 6.

If we then divide each term by 2, we get the final result of y = -1/2x + 3.

Here we see that the slope (m) is equal to -1/2, and the y-intercept (b) is 3.
