the maximum load of elevator is 480 pounds. Assuming that the average mass of student is 45 pounds, and m represents the number of students in the elevator, how many students can take the elevator at the same time

Answers

we can use the equation 45m < 481

we can replace m to see where it caps.

and the cap is 10.

we can replace m to check our work

45(10) < 481

450 < 481

if you add another student, it would go over the limit.

hope this helps :D

You earn $45.50 each year on an investment. What is the rate of simple interest if your initial investment was $750?

Answers

6.0666...%

You probably need to round it to the nearest tenth (6.1%) or hundredth(6.07%). If you need to the nearest thousandth, it is 6.067%.

Interest/Investment = the percent interest (or return)

$45.50/$750=0.060666...

Kelly's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 4 single-shot espressos and 6 double-shot espressos. What percentage of the espressos sold were single-shot?

Answers

Answer:

40% of espresso was single-shot.

Step-by-step explanation:

To make a percentage, you need to think of a fraction first. The denominator is always 100 in a percent. If my answer is 40%, the fraction would be 40/100. If there was 6 double shots and 4 single shots, those two together would make 10. 10 x 10 is 100. So really, you just have to multiply 4 by 10 to get the percentage.

Hope this helped, if your confused, just ask me :]

a wildlife manager determines that the function y=200x1.07* represents the deer population at a state park x years after the population is first counted. what is the population after 12 years? what is the initial population? what is the percentage rate? complete the table below.

Answers

4, 262

8,344

12, 450

Population after 12 years is 450 deer

Initial population is 200 deer.

Step-by-step explanation:

You take the x in the table and plug it in as an exponent so you will need a calculator or multiple the 1.07 by that many times so 1.07 12 times multipled by itself. and the initial is 0 years so anything to the exponent of 0 is 1 so that show i got 200 for the x=0
