Answer:

y^6, 12n^6, 20x^9

Step-by-step explanation:

When you multiply like variables with each other, you add their powers together.

So...

1.   (y^2)(y)(y^3)\\y^{2+1+3} \\y^6

2.  (3n^2)(4n^4)\\12n^{2+4}\\12n^6

3.  (5x^4)(4x^5)\\20x^{4+5}\\20x^9

padilas [110]

Answer:

V = π6²6 - (1/3)π6²6

Step-by-step explanation:

Volume of a cone is (1/3) that of a cylinder with the same radius and height.

Container A volume is the volume of a cylinder minus a cone.

V = πr²h - (1/3)πr²h

V = π6²6 - (1/3)π6²6

V = 144π units³

Solve the problem. if a roof has a pitch of 5 to 11, how high will the roof rise over a 33-foot run?
Katyanochek1 [597]
Pitch = rise/span = rise/(2 x run)
5/11 = rise/(2  x 33) = rise / 66
rise = 66 x 5/11 = 30 feet.

What is the solution to the equation?<br> 3/4(4c+16)=2c+9
ella [17]
<span>3/4(4c+16)=2c+9

We simplify the equation to the form, which is simple to understand
<span>3/4(4c+16)=2c+9

Reorder the terms in parentheses
<span>+(+3c+12)=2c+9

Remove unnecessary parentheses
<span>+3c+12=+2c+9

We move all terms containing c to the left and all other terms to the right.
<span>+3c-2c=+9-12

We simplify left and right side of the equation.
<span>+1c=-3

We divide both sides of the equation by 1 to get c.
<span>c=-3
Hope this helped! :)
