One way is to create a factor tree for each number. Then see which factors they have in common.
Example:
12 30
^ ^
2 6 3 10
^ ^
2 3 2 5
The factors are the underlined numbers above:
12: 2 x 2 x 3
30: 2 x 3 x 5
The common factors are: 2, 3, and 6 why 6? because 2 x 3 = 6
The greatest common factor is: 6
To find the common factors and the greatest common factor (GCF) of numbers, list all factors of each number, find the common ones, and identify the largest as the GCF. The factor-label method can simplify locating the GCF.
Explanation:To find the common factors and the greatest common factor (GCF) of two numbers, you start by listing all the factors of each number. These are whole numbers that can divide the numbers without a remainder. For example, the factors of 12 are 1, 2, 3, 4, 6, and 12, and the factors of 18 are 1, 2, 3, 6, 9, and 18.
Common factors are factors that the two numbers share. In our example, the common factors of 12 and 18 are 1, 2, 3, and 6.
The greatest common factor (GCF) is the largest of these common factors. This helps in multiplication and division of numbers, particularly when simplifying fractions. Here, the GCF of 12 and 18 is 6.
To find the GCF more quickly, you can use the factor-label method. Divide both numbers by a common factor and continue this process with the resulting numbers until you can't find any common factors other than 1. The GCF is the product of all the common factors you used to divide.

How many cases of 12 do you need to fill 159
You need a total of 14 cases of 12 to fill 159 items. This involves dividing 159 by 12 and rounding up the result. The division results in 13.25, which means you need 14 cases.
To determine how many cases of 12 are needed to fill a total of 159 items, you can use division:
Divide the total number of items by the number of items per case: 159 ÷ 12 ≈ 13.25Since you can't have a fraction of a case, you need to round up to the next whole number. Therefore, you need 14 cases.So, you need a total of 14 cases to completely fill 159 items.

Answer:
Step-by-step explanation:
(2005, 12,000) (2005, 12,000)
x1 y1 x2 y2
m= (12,250-1200) / (2010-2005) = 250/5 = 50/1 = or 50
The nth term of the arithmetic sequence 7, 10, 13, 16, ... is described by the equation an = 3n + 4, which is option (a).
To find the nth term of the arithmetic sequence 7, 10, 13, 16, ..., we need to recognize that this sequence has a common difference of 3, because each term increases by 3 from the previous term. The general formula for an arithmetic sequence is an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, and d is the common difference.
In this sequence, a1 is 7 and d is 3. Plugging these values into the general formula, we get:
an = 7 + (n - 1)*3
an = 7 + 3n - 3
an = 3n + 4
Therefore, the correct equation that describes the nth term of this arithmetic sequence is option (a): an = 3n + 4.

The county fair charges $2.50 per ticket for the rides. Henry bought 15 tickets for the rides and spent a total of $55.50 at the fair. Henry spent his money only on ride tickets and far admission. The price of the fair admission is the same for everyone. Use x to represent the number of tide tickets and y to represent the total cost.
(A) Find the cost of admission to the fair. Explain how you found the cost of admission.
(B) Write a linear equation that can be used to determine the cost for anyone who pays for ride tickets and fair admission.
(C) Explain what the coefficient on x and the constant of your linear equation represent.
To find the cost of admission to the fair, subtract the cost of the ride tickets from the total spent. The linear equation for cost of ride tickets and admission is y = 2.50x + 18. The coefficient represents the cost per ride ticket, while the constant term represents the cost of admission.
Explanation:(A) To find the cost of admission to the fair, we need to subtract the cost of the ride tickets from the total amount spent. Since Henry bought 15 ride tickets for $2.50 each, the cost of the ride tickets would be 15 * $2.50 = $<<15*2.5=37.5>>37.50. So, the cost of admission to the fair would be the difference between the total amount spent and the cost of the ride tickets: $55.50 - $37.50 = $<<55.50-37.50=18>>18.
(B) The linear equation to determine the cost of ride tickets and fair admission can be expressed as y = 2.50x + 18, where y represents the total cost and x represents the number of ride tickets.
(C) The coefficient on x, which is 2.50, represents the cost per ride ticket. The constant term of 18 represents the cost of fair admission.

Todd is at the grocery store purchasing ingredients for homemade granola. He needs x ounces of almonds, which are priced at m dollars per ounce in the baking section. The total cost of the other ingredients is b dollars. The following expression represents the total amount of money that Todd will spend on all of the granola ingredients.
Todd later finds almonds in the bulk section that are half the price of those in the baking section. If he purchases the almonds in the bulk section, which of the following statements are true about the given expression?
The value of x will change because that is the price of the almonds
Therefore mx will change
And the value of mx+b will decrease because the price is cheaper
Answer:
The correct statements are :
1. The value of mx will change.
2. The value of m will change.
3. The value of mx+b will decrease.
Step-by-step explanation:
Todd needs x ounces of almonds, which are priced at m dollars per ounce in the baking section. So, price of x ounces becomes = mx
The total cost of the other ingredients is b dollars.
Hence, total cost is given as = [tex]mx+b[/tex]
Now, Todd later finds almonds in the bulk section that are half the price of those in the baking section.
So, now price is :[tex]\frac{m}{2}[/tex]
And total price for 'x' ounce will become: [tex]\frac{mx}{2}+b[/tex] dollars.
Therefore, if Todd purchases the almonds in the bulk section, the total cost will decrease.

What pair of square numbers gives a difference of 1100
Let us assume numbers are x and y.
Difference of the squares of x and y = 1100.
We can setup an equation:
x^2 - y^2 = 1100.
We can apply difference of the squares formula: a^2-b^2 = (a-b)(a+b).
Therefore,
x^2 - y^2 = 1100 would become (x-y)(x+y)=1100.
Let us find all factors of 1100 square of those differences is 1100.
Let us take factors of 1100 as 110 and 10.
Sum should be 110 and difference should be 10.
So, we could setup two eqautions as
x+y=110
x-y=10
Adding equations, we get
2x = 120.
Dividing both sides by 2, we get
x=60.
Plugging x=60 in x+y=110, we get
60+y=110.
y=50.
Therefore, 60 and 50 pair of square numbers gives a difference of 1100.

While hiking, Mr.Finds burns 808 Calories in 8 hours. At this rate, how many Calories does he burn in 60 minutes?
Answer:
Mr Finds burns 101 calories in 60 minutes.
Step-by-step explanation:
We were given that Mr Finds burns [tex]808[/tex] calories in [tex]8[/tex] hours.
So we can write the ratio,
[tex]808:8[/tex]
At the same rate we want to find how many calories he burns in [tex]60[/tex] minutes.
This is equivalent to asking how many calories he burns in an hour.
Let [tex]x[/tex] represent the number of calories he burns in an hour. Since this should obviously be less than 808, we divide by 8 to get,
[tex]x=\frac{808\times 1}{8}[/tex]
[tex]\Rightarrow x=101[/tex]
Therefore Mr Finds burns 101 calories in 60 minutes.
Answer:
101 calories.
Step-by-step explanation:
We are told that while hiking, Mr.Finds burns 808 Calories in 8 hours.
To find calories burn by Mr. Finds in 60 minutes let us find calories burn per hour as 1 hour equals 60 minutes.
[tex]\text{Calories burn in 1 hour}=\frac{808\text{ Calories}}{8\text{ Hours}}[/tex]
[tex]\text{Calories burn in 1 hour}=101\frac{\text{ Calories}}{\text{ Hour}}[/tex]
Therefore, Mr. Finds will burn 101 calories in 1 hour or 60 minutes.
