For problems like these, we use something called a
ceiling function, in which
![\lceil{x}\rceil = \text{the smallest integer that is greater than or equal to x}](https://tex.z-dn.net/?f=%5Clceil%7Bx%7D%5Crceil%20%3D%20%5Ctext%7Bthe%20smallest%20integer%20that%20is%20greater%20than%20or%20equal%20to%20x%7D)
. If we do
![\lceil1000 / 72\rceil](https://tex.z-dn.net/?f=%5Clceil1000%20%2F%2072%5Crceil)
, we get that we do
![\lceil13.888...\rceil](https://tex.z-dn.net/?f=%5Clceil13.888...%5Crceil)
, which is
14 buses. We take the ceiling of the division because if we don't, we know that there are going to be extra kids left over that won't be able to seat on a bus. If we just rounded down to 13 buses, we would have been able to seat only 936 kids, a full 64 kids left over.
You set it up like:
5.4days x (24 hours/1 day) x (60 minutes/1 hour)
you get 7776 minutes
Answer:
percentage decrease is 70%
Step-by-step explanation:
To find percentage decrease of 2 quantities, we have to find the difference of the quantities and divide by the original quanity. Then we multiply by 100 to find the PERCENTAGE.
We will use formula:
![\frac{New-Old}{Old}*100](https://tex.z-dn.net/?f=%5Cfrac%7BNew-Old%7D%7BOld%7D%2A100)
Where
"New" is the latest quantity
"Old" is the first (previous) quantity
Here, New = 5.3 & Old = 17.71
We substitute into formula and find:
![\frac{New-Old}{Old}*100\\=\frac{5.3-17.71}{17.71}*100\\=-0.700*100\\=-70](https://tex.z-dn.net/?f=%5Cfrac%7BNew-Old%7D%7BOld%7D%2A100%5C%5C%3D%5Cfrac%7B5.3-17.71%7D%7B17.71%7D%2A100%5C%5C%3D-0.700%2A100%5C%5C%3D-70)
So we can say that the percentage decrease is 70%
