Cami goes scuba diving. She descends 18 feet in 3 minutes. Which expressions represent the average rate at which Cami’s position
julsineya [31]

Answer:

6 ft/min

Step-by-step explanation:

Theres a neat trick to note; whenever you say per think of it as a fancy word for divide, because the label is always gonna be a/b (a per b)

Therefore,

the rate of feet per minute will be the feet divided by the minutes;

18 feet in 3 minutes = <u>18</u>/3 <u>ft</u>/min

Therefore the rate is 6 feet per minute.

<u>IF you need an explanation on what average rate implies:</u>

<em>Note; the word average is not prudent to answer as its extraneous, however if there was more data like "Cami descends 18 ft in 3 min and Nami descends 9 ft in 3 minutes; whats the average rate at which they descend" then you'd have to add the two rates up and divide by two.</em>

Hope this helps :)

vaieri [72.5K]

Answer:

60

Step-by-step explanation:

After adding 88 red marbles, there are 50 blue marbles out of the 204 marbles total.

Let the number of blue marbles to be added be x.

\frac{50+x}{204+x}=\frac{5}{12} \\ \\ 600+12x=1020+5x \\ \\ 420=7x \\ \\ x=60

The answer is: he can eat 48 hotdogs in 12 minutes. How? Well, first, to find the amount of hotdogs he can eat in 1 min. you have to divide 32 by 8, and obviously you get 4. Now you multiply 4 by 12 and you get your answer, which is 48. Good luck with your homework!

If $500 is invested at 8% annual interest, how much will be in the account after 3 years if it's compounded quarterly?
Alchen [17]

Answer:

FV= $634.12

Step-by-step explanation:

Giving the following formula:

Initial investment (PV)= $500

Number of periods (n)= 3*4= 12 quarters

Interest rate (i)= 0.08/4= 0.02

<u>To calculate the future value, we need to use the following formula:</u>

FV= PV* (1 + i)^n

FV= 500*(1.02^12)

FV= $634.12
