Rachel found that the time it takes for her to make her favorite desert decreases the more times she makes its. The time is takes in minutes(M) can be modeled by: M=72-0.75n, where n is the number of times that rachel has made the desert.
A. how long will it take rachel to make her desert the fifth time?

B. after how many times will rachel be able to make her desert in 63 minutes?

C. How long will it take rachel to make her desert the 40th time? Do you think this is reasonable?

Answers

Answer 1

Answer:

A: 68.25 minutes

B: 12 times

C: 42 mins and you decide this part I actually don't know. But I think it could be reasonable, after 40 times someone should get pretty good at it.

Step-by-step explanation:

a: 72 -0.75*5 = 68.25

b: M=63=72-0.75n

subtract 72 from each side: -9 = -0.75n

divide each side by -0.75: n = 12

so 12 times

c: 72 - 0.75(40) = 42 minutes. Now this could be is reasonable, but we don't know what their desert is. But 40 times is a lot of practice.

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

She has 5 cups of grapes, 3 pints of strawberries, and 1 quart of watermelon pieces.

2. If she wants to share the fruit salad between herself and 5 friends, how much fruit salad will each person get?
Answer both to get brainlest. Also please explain.

Answers

1. I believe she would have 15 cups of fruit salad because it’s 5 cups of grapes, 6 cups strawberries(1 pint = 2 cups which means 6 cups of strawberries) and 4 cups of watermelon (1 pint = 4 cups
2. Since there are 15 cups of fruit salad you would need to divide 15 by the number of friends which would make it 2.5 cups of fruit salad per person
1.) 15 cups
2.) 3 cups per person
