Answer:
<em>Maya needs 33 bags</em>
Step-by-step explanation:
Let's call x the number of bags of soil. If each bag contains 1.5 cubic feet, then "x" bags do not contain a volume of:
1.5x.
As a volume of 4.5 cubic feet has been published.
We need 54 cubic feet.
Then
Now we must solve the equation for x.
Because there are 24 hours in a day, we're going to use that.
y = 13(24x)
However, this is interpreting that Joy works 24 hours a day, every day, which is impossible.
Without knowing the daily hours, this will not be accurate.
However, this is how much Joy would make if they worked 24 hours a day.
Ok so there are no real solutions for xy=15000 and x+y=5
there are immaginary solutions though so
xy=15000
x+y=5
x+y=5
y=5-x
x(5-x)=15000
-x^2+5x=15000
0=x^2-5x+15000
quadriacic formula
if ax^2+bx+c=0, then
x=
x^2-5x+15000
a=1
b=-5
c=15000
x=
x=
x=
x=
so the numbers are
and
Alright so 4 students rode in cars so do 490-4=486
Now do 486 (# of students riding bus) divided by 9 (how many buses) which gets u 54
So 54 students were on each bus
