P(over 40, root beer drinker) = 30/85 = 6/17
answer
6/17
You've been working with rectangular prisms all night, and the same formula gives the volume of every one of them. Unfortunately, you used way more time asking other people for answers than it would take you to solve them on your own.
The formula is:
Volume = (length) times (width) times (height) .
With that formula, you can directly solve problems #1, #2, #3,
#4, and #8. It's also the only math you really need to solve #9 ...
but you also need to use your brain cells for #9.
For #6, start with the same formula:
Volume = (length) x (width) x (height)
Divide each side by
(width) x (height), and
then it says: Length = (volume) / (width x height) .
#6 gives you the volume, width and height.
You can just write them into this equation,
and bada-bing, you'll have the missing length.
You can write the amount that they spent individually in a ratio where:
Holly : Jimmy
2 : 5
The total of this ratio would be 2+5 = $7.
To find the scale factor multiplier for the base ratio of 2:5:
35/7 = 5
Multiply both sides of the ratio by 5.
Holly : Jimmy
2 x5 : 5 x5
10 : 25
You can see that the total of this ratio is now $35, where Jimmy spent $25.
X =15
Then plug 15 for each x value
