Write 24 as a product of primes.
Use index notation when giving your answer.​

Answers

Answer:

2^3 * 3

Step-by-step explanation:

Here are the first several prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23

To find the prime factorization of a number, start by dividing the number by the smallest prime number it is divisible by. Keep dividing by that prime number until you can't anymore. You only divide by prime numbers that divide evenly. Then move on to the next prime number that divides evenly, and do the same. You eventually will get to 1. Then you put together all the prime factors.

This is much easier to do than it sounds like in this explanation.

Start with 24.

24/2 = 12

12/2 = 6

6/2 = 3    3 is not divisible by 2, so we move on to 3.

3/3 = 1    We got to 1, so we are done.

The prime factorization is the product of all the prime numbers we divided by which are in bold.

24 = 2 * 2 * 2 * 3

Now we index it:

24 = 2^3 * 3

Answers

Answer:

m = 2

Step-by-step explanation:

The given equation is :

8x – 4y - 9 = 0

The general equation of a line is given by :

y = mx+b ...(1)

here m is slope and b is y-intercept

Equation (1) can be written as :

8x – 4y = 9

Dividing both sides by (-4)

[tex]\dfrac{8x}{-4}-\dfrac{4y}{-4}=\dfrac{9}{-4}\\\\-2x+y=-\dfrac{9}{4}\\\\y=2x+\dfrac{-9}{4}[/tex] ...(2)

Comparing equation (1) and (2), we get :

m = 2

Hence, the slope of the line is 2.

Emilio has 2 quarters, 4 dimes, 3 nickels, and 5 pennies.

Quarters = 0.25 * 2

Dimes = 0.1 * 4

Nickels = 0.05 * 3

Pennies = 0.01 * 5

$0.50 + $0.40 + $0.15 + $0.05

Garden soil costs $5.00 per a 2 cubic foot bag at lows. You have raised rectangular garden thag is 8 feet by 4 feet and you wish the depth of the soil to be 6 inches deep. How much will it cost to buy the bags of soul for your garden

Answers

Answer:

$40

Step-by-step explanation:

Step one:

given data

Garden soil costs $5.00 per a 2 cubic foot bag

dimension of rectangular garden raised

8 feet by 4 feet , depth is 6 in

6 in to feet= 0.5ft

the volume of the soil in the  garden is

volume= 8*4*0.5= 16ft^3

Step two:

now if 2ft^3 cost $5

         16ft^3 will cost x

cross multiply

x*2=16*5

divide  both sides by 2

x= 16*5/2

x=80/2

x=$40

CJ wants a new video game but is not sure which one to buy. His choices are 5 sports games, 3 role-playing games, and 8 action games. He writes the game titles on pieces of paper and puts them all in a bag. He wants to buy two different games. If he randomly selects two names from the bag, what is the probability that CJ selects two sports games?

Answers

Answer:

1 /12

Step-by-step explanation:

Given that:

Number of sports game = 5

Role playing games = 3

Action games = 8

Total = (5 + 3 + 8) = 16

The probability of selecting two sports game from the bag :

First selection = sport game and second selection will also be a sport game.

This scenario with be a selection without replacement pattern

First selection :

Number of sports game / total number of options

5 / 16

SEcond selection : total left = 16 - 1 = 15 ; number of sports game = 5 - 1 = 4

Hence

P(sports on second selection) = 4 / 15

P(sports on first and second) :

5/ 16 * 4/15 = 20/ 240 = 1 / 12

2. When 9 is added to the number that is produced by tripling the number x, the result is
equal to 6 times the number that is 3 less than x. Write an equation to represent the
situation and use it to find the value of x.

Answers

The equation that represents the situation is:

9 + 3x  =  6(x  -  3)

The value of x is x = 9

Word problem on linear equation

Let the number be represented by x

Triple the number = 3x

9 added to the number that is produced by tripling the number x = 9 + 3x

3 less than x  = x - 3

6 times the number that is 3 less than x = 6(x - 3)

Therefore, the equation that illustrates the situation is:

9 + 3x  =  6(x  -  3)

Solve for x in the equation above

9 + 3x = 6x  -  18

6x  -  3x  =  9  +  18

3x   =  27

Divide both sides by 3

3x/3  =  27/3

x  =  9
