1 gallon = 4 * 32 = 128 ounces
20 cups x 10 ounces = 200 ounces
200 / 128 = 1.56 bottles
she will need to buy 2 bottles
The total surface area is 2w² + 8/w, while the total cost is $(20w² + 160/w)
<h3>What is
volume?</h3>
Volume is the amount of space occupied by a three dimensional shape or object.
Let w represent the width of the base and h represent the height. Hence:
w²h = 2
h = 2/w²
The surface area = 2w² + 4(hw) = 2w² + 4(2/w² * w) = 2w² + 8/w
The total cost = 2w² * $10 + (8/w) * $20 = $(20w² + 160/w)
The total surface area is 2w² + 8/w, while the total cost is $(20w² + 160/w)

Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: She does not have a heart attack.
Event B: tests predicts that she will have a heart attack
The doctors told her that the reliability of the stress test is 67%.
This means that there is a 100 - 67 = 33% of not having a heart attack if the test predicts she will have a heart attack, so:
70% risk of heart attack
So 100 - 70 = 30% probability of not having a heart attack, which means that 
What is the probability that Erin will not have a heart attack and the test predicts that she will?
The correct answer is given by option A.
Answer:
Step-by-step explanation:
Let the five consecutive integers be (x - 2 ) , (x - 1) , (x) , (x + 1) , (x + 2)
(x - 2 ) + (x - 1) + (x) + (x + 1) + (x + 2) = 110
x - 2 + x -1 + x + x +1 + x + 2 = 110
5x = 110
x = 110/5
x = 22
The consecutive numbers are: 20,21,22,23,24
The volume of a cube is given by;
(One length side of the cube)³ - remember all sides of a cube are the same, just like how both sides of a square are the same. This is essentially the area of the square at the base, multiplied by the height of the cube.
Hence why we that that, for example 4³, is "4 cubed"
So we know that;
volume = (side length)³
Alternatively we could say that;
Side length = ∛volume
(we have just found the cube root of both sides here, remember we can do what we like to an equation, as long as we do the same to both sides!)
Because we cubed side length to get volume, side length must be the cubic root of the volume, the ∛.
We know that the volume is 1000 cubic feet, so;
Side length = ∛1000
∛1000 = 10
So one side length is 10 feet.
