A popcorn container is the shape of an inverted cone. it is 9 inches tall, and the circular opening has a diameter of 4 inches.

Tamiku [17]

The expression that determines the volume of the container is $V = \frac 13 * \pi * 2^2 * 9$

<h3>How to determine the volume expression?</h3>

The given parameters are:

Shape = Cone
Height, h = 9 in
Diameter, d = 4 in

The volume of the cone is calculated using:

$V = \frac 13 * \pi (d/2)^2h$

So, we have:

$V = \frac 13 * \pi (4/2)^2 * 9$

This gives

$V = \frac 13 * \pi * 2^2 * 9$

Hence, the expression that determines the volume of the container is $V = \frac 13 * \pi * 2^2 * 9$

1+Sin/Cos + Cos/1+Sin = 2Sec

Bond [772]

Step-by-step explanation:

Consider the left-hand side:

$\dfrac{1+\sin{\theta}}{\cos{\theta}} + \dfrac{\cos{\theta}}{1+\sin{\theta}}$

$\:\:\:\:= \dfrac{(1+\sin{\theta})^2 + \cos^2{\theta}}{\cos{\theta}(1+\sin{\theta})}$

$\:\:\:\:=\dfrac{1+2\sin{\theta}+\sin^2{\theta} + \cos^2{\theta}}{\cos{\theta}(1+\sin{\theta})}$

$\:\:\:\:=\dfrac{2+2\sin{\theta}}{\cos{\theta}(1+\sin{\theta})} =\dfrac{2(1+\sin{\theta})}{\cos{\theta}(1+\sin{\theta})}$

$\:\:\:\:= \dfrac{2}{\cos{\theta}} = 2\sec{\theta}$

A number problem states, “–5 times a number, minus 22 gives a result of 23.” What is the number?

Serggg [28]

Answer:

im pretty sure its -9

Step-by-step explanation:

the equation explained would look something like this...

-5x-22=23

so you would isolate the variable by first adding 22 to both sides and the dividing by -5 on both sides

-5x-22=23

+22 +22

-5x/-5=45/-5

x=-9

An integer is chosen at random from 1 to 50 inclusive. Find the probability that the chosen integer is divisible by 3. A- 3/50 B

11111nata11111 [884]

First, we need to know how many things between 1 and 50 are divisible by 3, this would be 16. Then we would divide this by the total number of integers, 16/50=8/25. This means your answer is C.
