Well we already know that the 36:100 is correct because it is the starting amount, to check the 18:50 50 is half of the 100 insects so you would divide 36 by 2 which gives you half of 36 which is 18 so we can check off 18:50 as correct. Idk about the final one but the other two are correct.

10,000 is compounded quarterly at 12% interest for t years, what expression represents the amount of money after t years
Murljashka [212]

Answer:  10,000(1.03)⁴ˣ  

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

A = P(1 + \frac{r}{n})ⁿˣ

A is the amount (new balance):  <u> unknown </u>

P is the principal (amount you started with):  <u> 10,000 </u>

r is the interest rate: 12% = <u> .12 </u>

n is the number of times per year it is compounded: quarterly = <u> 4 </u>

x is the number of years: <u> x </u>

A = 10,000(1 + \frac{.12}{4})⁴ˣ

   = 10,000(1 + .03)⁴ˣ

   = 10,000(1.03)⁴ˣ

Alexeev081 [22]

Answer:

Choice B) No.

Step-by-step explanation:

When she starts , she does a sit-up every 222 seconds.

But as she gets tired, each sit-up takes longer and longer to do.

It means, each sit-up takes more time than she did at beginning.

So, it is NOT proportional to the time.

If it is proportional, she should take constant number of sit-ups even she get tired.
