Answer:
The last one is incorrect
Speed=6 miles per hour
Distance =9.6 miles
Speed =distance /time
Time=distance/speed=9.6/6=1.6 hours
Answer:
1
Step-by-step explanation:
ANSWER
The constant of proportionality is 24.
EXPLANATION
If the volume of a box (V) varies directly with it's length (l), then we can write the mathematical statement,
![V\propto l](https://tex.z-dn.net/?f=V%5Cpropto%20l)
We introduce the constant of proportionality k, and write the equation,
![V = k l](https://tex.z-dn.net/?f=V%20%3D%20k%20l)
When V=288, l=12.
We substitute these values to obtain;
![288 = 12k](https://tex.z-dn.net/?f=288%20%3D%2012k)
Divide both sides by 12,
The first step to solve this problem is to compute for the
total money of Veronica. You can do this by:
$35 (given to bill) / 20% (percentage of her money given to
Bill) = $175
Since you already know the total money of Veronica, you can
now compute how much she spent to buy books which are 50% of her remaining
money after giving Bill $35.
($175 - $35) x 50% = $70
Therefore, she spent $70 for her books.
$175 – $35 – $70 = $70
Therefore, she has $70 left.
