Answers
You can't factor it.
Answer:
(x - 2)(x - 4)
Step-by-step explanation:
Given
x² - 6x + 8
Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (- 6)
The factors are - 2 and - 4, since
- 2 × - 4 = + 8 and - 2 - 4 = - 6, then
x² - 6x + 8 = (x - 2)x - 4) ← in factored form

What is the percent change from pre-cooked weight to final weight?
Answers
Answer:
new = 1/3 old = 1/2
new - old = 1/3 - 1/2 = 2/6 - 3/6 = -1/6
dividing by the old: -1/6 divided by 1/2 = -1/6 * 2/1 = -1/3
multiplying by 100% : -100/3 = -33 and 1/3 %
It is a 33 and 1/3 % DECREASE

3/2 : 1
This means that the hot chocolate was more by 1.5
As a fraction; 3/2
Check:
1.5 * 2/8 = 3/8

Tim would have 102 ft of wrapping paper left.
$9,800,000 is what percent of $7,000,000
Answers
Answer:
686000000000
Step-by-step explanation:
1. We assume, that the number 7000000 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 7000000 is 100%, so we can write it down as 7000000=100%.
4. We know, that x is 9800000% of the output value, so we can write it down as x=9800000%.
5. Now we have two simple equations:
1) 7000000=100%
2) x=9800000%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
7000000/x=100%/9800000%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 9800000% of 7000000
7000000/x=100/9800000
(7000000/x)*x=(100/9800000)*x - we multiply both sides of the equation by x
7000000=1.0204081632653E-5*x - we divide both sides of the equation by (1.0204081632653E-5) to get x
7000000/1.0204081632653E-5=x
686000000000=x
x=686000000000
now we have:
9800000% of 7000000=686000000000

What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.
