Afull container that holds 96 fluid ounces developed a leak in the bottom. after 72 hours, all the liquid had emptied from the container. what was the average rate at which the liquid drained from the container, in fluid ounces per hour?

1.3 fl oz/h

Step-by-step explanation:

Let

The average rate at which the liquid drained from the container is equal to the quotient between y and x. Then, the appropriate algebraic operation is the division.

y/x = 96 fl oz/72h = 1.3 fl oz/h

the ratio of grapes to blueberries she should use is 12: 3

step-by-step explanation:

if mandie is making 15 cups of fruit salad, the ratio of grapes to blueberries she should use is 12: 3.

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
