P = 2(L + W)
P = 2(400 + 200)
P = 2(600)
P = 1200 ft......
I am assuming that is 12 dollars per yard...
1 yd = 3 ft
1200/3 = 400 yds...at 12 per yd....12 * 400 = $ 4800 <==
its some t.v show I guess
Answer:
The zeros are 6,-5,9
Step-by-step explanation:
The factored form of the polynomial is given as:
To find the zeros of this function, we set f(x)=0 and solve for x.
This implies that:
We solve for x to get:
The zeros are 6,-5,9
By solving a linear equation, we will see that the total cost for renting the bus is $90.
<h3>What was the total cost of renting the bus, in dollars?</h3>
Let's say that the total cost is C.
When there are 20 students, each student should pay:
p = C/20
When the other 10 students are added (for a total of 30) each student pays:
p' = C/30.
We know that the cost for each of the original 20 students decreased by $1.50, so:
p' = p - $1.50
Then we have 3 equations to work with:
p = C/20
p' = C/30.
p' = p - $1.50
Now we can replace the first and second equations into the third one:
C/30 = C/20 - $1.50
Now we can solve this linear equation for C:
C/20 - C/30 = $1.50
C*( 1/20 - 1/30) = $1.50
C*(30/600 - 20/600) = $1.50
C*(10/600) = $1.50
C*(1/60) = $1.50
C = 60*$1.50 = $90
So the total cost for renting the bus is $90.
