The GCF two numers is a composite number. Always, sometimes or never true?

Answers

Answer 1
Answer:

Answer:

Sometimes

Step-by-step explanation:

A Composite number is the number which is not prime except 1. Hence, it has factors other than 1 and itself.

GCF is a greatest common factor i.e. the greatest factor that divides two numbers.

The GCF of two numbers can be composite number.

Example:

GCF of 8 and 24 = 8 which is a composite number.

GCF of 6 and 21 = 3 which is not a composite number.

Thus, GCF two numbers is sometimes a composite number.
Answer 2
Answer: The GCF of two numbers is sometimes a composite number.

How many milligrams of calcium are in 100 grams of beef, if the beef has 12 milligrams of calcium? Please explain how you did it. -thanks!

Answers

You must also know the total weight of the beef. You forgot to mention it but let's say the beef weighs 450 grams and is known to contain 12 milligrams of calcium. Then the amount of calcium per 100 grams would be found like this: 12mg ... 450g, xmg ... 100g <=> x = 100*12/450 <=> x = 120/45 <=> x = 2.66mg

The length of a rectangle is 2 inches more than twice its width.Write an equation relating the length/of the rectangle to its width w.

Answers

the equation would be: L= 2w + 2

What is equation?

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.

here, we have,

The length of a rectangle is 2 inches more than twice its width.

Let, width = w & length = L

now,

Since the length is 2 inches more than twice the width, the equation would be:

L= 2w + 2

Hence, the equation would be: L= 2w + 2

The value of 6n(n−1)+4, when n=3 is 40

Final answer:

The value of the mathematical expression 6n(n−1)+4 when n=3 is 40. This involves plugging in the value of n=3 into the expression and simplifying it according to the order of operations.

Explanation:

This is a simple math algebra problem about plugging in values and solving expressions. The given equation is 6n(n−1)+4, and we are asked to find the value when n=3. Let's start by replacing n with 3 in the equation.

So, 6n(n-1)+4 becomes 6*3*(3-1)+4. Simplifying inside the parenthesis first (according to the order of operations), we get 6*3*2+4, which becomes 18*2+4, then 36+4. Finally, that simplifies to 40.

So, the value of 6n(n-1)+4, when n=3 is 40.

(2 5/8 + 2 1/2) - 4 2/3

Answers

Steps:
1. Do 2 5/8 + 2 1/2 by changing them so they have the same denominators. Since 2 goes into 8, 8 would be your common denominator.
2. Multiply 2 times 4 which equals 8. Multiply 1 times 4 which equals 4
3. Your new problem is 2 5/8 + 2 4/8
4. This equals 4 9/8 which equals 5 1/8
5. Do 5 1/8- 4 2/3 by multiplying both denominators and numerators by 3 and the second mixed number by 8
6. 8 times 3 equals 24
1 times 3 equals 3
7. 5 3/24
8. 3 times 8 equals 24
9. 2 times 8 equals 16
10. 5 3/24 - 4 16/24
11. Take from the whole number in 5 3/24
12. 4 27/ 24 - 4 16/24
13. Your answer is 11/24
You need to change the fractions so that they all have a common denominator (the bottom half of the fraction). So you have to fond a number that all three denominators go into. You have 8, 2, and 3. They all go into 24. Times all the fractions by whatever they need to make the bottom 24. but you can only times them by 1, or else it will ruin your equation. [3/3 x 5/8 = 15/24] [12/12 x 1/2 = 12/24] [8/8 x 2/3 = 16/24] now plug your new fractions into the problem. (2 15/24 +2 12/24) - 4 16/24. simplify the part in the parenthesis first, (4 27/24) - 4 16/24. since you are subtracting, you can leave the part in parenthesis as a wrong fraction. now subtract. 4 27/24 - 4 16/24 = 11/24. you can't simplify that to be a smaller number, so that is your answer:)[11/24]

You want to buy the bicycle that is $116. You already have $43.50 saved and plan to save an additional $7.25 every week.Part A: Write and solve an equation to find the number of weeks you need to save before you can purchase the bicycle.

Part B: How much sooner could you purchase the bicycle is you had a coupon for $20 off and saved $8.75 every week? Explain your reasoning. 

PLEASE HELP! I'M IN 7th GRADE...AND I NEED TO GET MY MATH HOME WORK DONE, AND MY PARENTS AR'NT HOME TO HELP MEE..THANK YOU!

Answers

A. since you already have $43.50 already saved you subtract that from the amount the bike cost so you can see how much more needs to be left to save and that gives you $72.50. Then you divide the amount your saving up every week from that. So $72.50 divided by $7.25 is 10 and thats how many weeks it will take to save.

B. Since you still have that $43.50 saved and you have a coupon for $20 dollars off . Add those together to see how much you have saved up which equals $63.50. The bike is $116 so you subtract the amount you have for the bike from $116 which is $63.50 and that equals $52.50 and thats how much more money you need. Then divide how much money needed by the amount your saving up a week, which is $8.75. So $52.50 divided by $8.75 is 6 and thats how many weeks it will now take to get the bike.
