Answer: after 40 seconds, the two tanks will have the same amount of water.
Step-by-step explanation:
Let x represent the number of seconds after which both tanks will have the same amount of water.
A fish tank has 150 gallons of water and is being drained at a rate of 1/2 gallons each second. It means that the number of gallons of water that would be in the tank after t seconds is
150 - 0.5t
A second fish tank has 120 gallons and it is being filled at a rate of 1/4 gallons each second. It means that the number of gallons of water that would be in the tank after t seconds is
120 + 0.25t
For the volume of both tanks to he the same, then
120 + 0.25t = 150 - 0.5t
0.25t + 0.5t = 150 - 120
0.75t = 30
t = 40 seconds
Ax^2+bx+c=0
a=2
b=-1
c=-3
b+-sqrt( b^2 - 4ac)
2a
so...
-1 +- sqrt(1 + 24)

-1 +- 5

x= -1 + 5 = 1
4
or
x= -1 - 5 = -3/2

Answer:
T-shirts = t
Price = 8.25
Coupon = - 5.00
p is total price.
t is number of t-shirts.
Function:
p = $8.25t - $5.00
How much would you pay during Bargain Days for 11 shirts?
t = 11
p = 8.25(11) - 5.00
p = 90.75 - 5.00
p = $85.75
Each successive term is 3 times the previous one, so you could write the sum as
I think if i understood it right its, 34.65
