Answer:

2/9^8

Step-by-step explanation:

3^0 = 1 so it turns into 9^-8/ 2^-1

Then put 9^-8 on the bottom to make it positive

Now its 1/9^8 & 2^-1

Then put 2 on top to make it positive and 2^1 is just 2

So now you have 2/9^8

You purchase 2 action figures per week. You have 48 action figures, which is 75% of the total number of action figures you need

LiRa [457]

Answer:

Step-by-step explanation:

Let the total number of action figures = x

75% of x = 48

$\dfrac{75}{100}*x=48\\\\Multiply \ by \ 100\\\\75*x =48*100\\\\Divide \ by \ 75\\\\x=\dfrac{48*100}{75}\\\\\\x=16*4\\\\x= 64$

Remaining action figures need to be collected = total figures - number of action figures I have

= 64 - 48 = 16

Number of weeks = 16 ÷ 2 = 8

It will take 8 weeks to collect 16 action figures.
