<span>If it is a right prism, then the cross-section area will be considered a rectangle. Each lateral face will be perpendicular to the base, and if we cut the plane it will be perpendicular to the bases and the resulting angles of the cross-section would all be simply right angles. 
Hence,
The best Answer would be third Option: A RECTANGLE.

An Exhibitor is selling decorative wreaths at an arts and craft show. The net profit P in dollars from the sales of the Wreaths
Svetradugi [14.3K]

<u>Given</u>:

An Exhibitor is selling decorative wreaths at an arts and craft show.

The net profit P in dollars from the sales of the Wreaths is given by P(n)=0.75n-50 , where N is the number of wreaths sold.

We need to determine the number of wreaths sold to earn a net profit of $100.

<u>Number of wreaths sold:</u>

The number of wreaths sold to earn a profit of $100 can be determined by substituting P(n) = 100 in the equation P(n)=0.75n-50, we get;

100=0.75n-50

150=0.75n

\frac{150}{0.75}=n

200=n

Thus, the number of wreaths sold is 200.

A group of entomologists has determined that the population of ladybugs at a local park can be modeled by the equation y = − 1.4
Oksanka [162]
<h3>Answer:</h3>

A) 177.568 thousand.

B) 125.836 thousand.

<h3>Step-by-step explanation:</h3>

In this question, it is asking you to use the equation to find the population of ladybugs in a certain year.

Equation we're going to use:

y = -1.437 x + 197.686

We know that the "x" variable represents the number of years since 2010, so that means our starting year is 2010.

Lets solve the question.

Question A:

We need to find the ladybug population is 2024.

2024 is 14 years after 2010, so our "x" variable will be replaced with 14.

Your equation should look like this:

y = -1.437 (14) + 197.686

Now, we solve.

y = -1.437 (14) + 197.686\\\\\text{Multiply -1.437 and 14}\\\\y=-20.118+197.686\\\\\text{Add}\\\\y=177.568

You should get 177.568

This means that the population of ladybugs in 2024 is 177.568 thousand.

Question B:

We need to find the ladybug population is 2060.

2060 is 50 years after 2010, so the "x" variable would be replaced with 50.

Your equation should look like this:

y = -1.437 (50) + 197.686

Now, we solve.

y = -1.437 (50) + 197.686\\\\\text{Multiply -1.437 and 50}\\\\y=-71.85+197.686\\\\\text{Add}\\\\y=125.836

This means that the population of ladybugs in 2060 would be 125.836 thousand.

Find the volume of a cone with a base radius of 3 cm and a height of 9 cm
katovenus [111]

The volume of a cone is 84.78 cm                

<u>Step-by-step explanation</u>:

<u>Given</u>:

radius = 3 cm and

height = 9 cm

<u>To Find</u>:

The Volume of a Cone

<u>Formula</u>:

The Formula for the volume of a cone is

V=πr2 *h/3

<u>Solution</u>:

V=πr2 *h/3

π value is 3.14

V= 3.14*(3)^2*9/3

V=3.14*9*3

V= 84.78 cm

Therefore the volume is 84.78 cm.
