Alright so .25 oz is 1/4 of 1oz. Therefore you take 28 and divide it by 4 and get 7.
Then take 3500 and divide it by 7 which makes 500 thumb tacks.
I think idk though.
<span>Because there are 20 coins plus four bars = 24 items to choose. You want to choose where to put the four bars, thus C(24,4). There are four bars, not five. Note that four bars divide the 20 coins into five sections. Five bars would divide it into six, but we only have five different kinds of coins to choose from.</span>
Answer:
14 inches
Step-by-step explanation:
The volume of a rectangular prism is V=l*w*h
Given the info in the problem, we have:
840=l*10*6
840=60l
14=l
The length of the prism is therefore 14 inches because volume is length*width*height and since we already have the volume, height, and width, we need to get the variable for length by itself.
