Answer:

210

Step-by-step explanation:

We can get 10% of 300 by doing 300 / 10 which is 30. 70 / 10 is 7, so we need 7 lots of 10% to work out 70%. Therefore, 30 * 7 students said that their favourite colour was blue, which is 210.

Answer:

210

Step-by-step explanation:

So 70% OF 300 students said their favorite color was blue

OF means multiply and 70% is equal to .70 so,

.70 x 300 = the number of students that said their favorite color was blue

                =210

So, the number of students that said their favorite color was blue is 210 students. :)

Marina CMI [18]

The correct answer I believe you are looking for is D. Elevator 1 is 13 feet above ground level, and Elevator 2 is 10 feet below ground level.

<u>Explaination:</u>

This is because if you start at (0, 0) Elevator one, will go up 13 on the y axis. Putting it at 13 feet above ground level. If you start Elevator 2 at ground level on (0, 0) and go down 10 it will make it -10 AKA 10 feet below ground level.


I hope this helps! :)

Bob sells part of a 50-acre rectangular plot of land he owns so that he can still own a smaller rectangular plot within the orig
Nuetrik [128]

Considering the area of a rectangle, it is found that the area of Bob's remaining plot of land is of 12.5 acres.

<h3>What is the area of a rectangle?</h3>

The area of a rectangle of length l and width w is given by the multiplication of these dimensions, that is:
A = lw.

In this problem, both the length and the width are divided in half, hence the proportion remaining is given by:

A = 0.5l x 0.5w = 0.25lw = 25% of the initial area.

Hence:

0.25 x 50 = 12.5.

The area of Bob's remaining plot of land is of 12.5 acres.
