Answer:

y = 65 degrees

Step-by-step explanation:

You can use a vertical angle to figure this out. Since 65 is a vertical angle to y, it equals the same amount. I have attached an image of an example of vertical angles. They are on the opposite side of the line.

The volume of a right circular cone is 300 cubic inches. What is the volume, in cubic inches, of a right cylinder that

Anna71 [15]

Answer:

The volume of a right cylinder is equal to the 3 times of the volume of a right circular cone.

Step-by-step explanation:

Given that,

The volume of a right circular cone is 300 cubic inches

We need to find the volume of a right cylinder that has the same base and height as the cone.

Volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2h$

And volume of a cylinder is given by :

$V'=\pi r'^2 h'$

If the base and height of cone and cylinder are same, r=r' and h=h'

$\dfrac{V}{V'}=\dfrac{1/3\pi r^2 h}{\pi r'^2h'}\\\\=\dfrac{1/3\pi r^2 h}{\pi r^2h}\\\\\dfrac{V}{V'}=\dfrac{1}{3}\\\\V'=3V$

So, the volume of a right cylinder is equal to the 3 times of the volume of a right circular cone.

What is the quotient of StartFraction 2 Superscript 4 Baseline Over 2 Superscript negative 4 Baseline EndFraction?

Tatiana [17]

Answer:

256

Step-by-step explanation:

Given. :

2⁴ / 2^-4

2⁴ = 2 * 2 * 2 * 2 = 16

2^-4 = 1/2⁴ = 1 / (2 * 2 * 2 * 2) = 1 / 16

16 ÷ (1 /16)

16 * 16 /1

= 256
