What is the prime factorization of 72? (1 point)
O 1x2x4x9
O 22x32
0 22x33
O 2x32

Answers

Answer:

2³×3²

Step-by-step explanation;

TO FIND A PRIME FACTORIZATION OF A NUMBER YOU FIRST NEED TO KNOW PRIME NUMBERS ARE;

Prime Numbers are numbers which which have only two factors the number itself and one

Examples of Prime Numbers are;

2,3,5,7,11,13,17,19,23,29,etc

To Find The Prime Factorization Of The Number 72 you'll need to follow this;

72=2×36(we have the number 36 because when it's multiplied by 2 the product is 72 and 36 is not a prime number so it has to be broken down but since 2 is a prime number you leave it as it is)

72=2×2×18(we have 2×18 because because it's give us the product of 36 when multiplied so now that we have a second prime number(2) we will have to continue to break down the number 18)

72=2×2×2×9( We again have two another 2 and 9 here because when multiplied by each other its product is 18 so as we can see 9 is not a prime number so we have to break it down but the 2 is a prime number so we let it be)

72=2×2×2×3×3( As we can see here, 3 and 3 is a prime number so nothing happens to it so we have broken the non-prime numbers down so now we have all the numbers as Prime Numbers)

So; 72=2×2×2×3×3

So we are going to count the twos and threes so as you can see we have three twos and we have two threes. Which makes our final answer;

2³×3²

So The Prime Factorization of 72 is; 2³×3²

Find the value of x.

Answers

Answer:

x = 19

Step-by-step explanation:

The sum of both angles will be equal to a supplementary angle. A supplementary angle is when two angles add up to be 180°. Write an equation and solve for x.

3x + 5 + 7x - 15 = 180

~Combine like terms

10x - 10 = 180

~Add 10 to both sides

10x = 190

~Divide 10 to both sides

x = 19

Best of Luck!

HELP PLS

Answers

Answer:

y=2/3x-7

Step-by-step explanation:

The slope intercept formula is

y=mx+b

(m) is the slope (rate of change)

(b) is the y intercept (where the line crosses the y axis [vertical])

We need to find the slope and the y intercept. First we will find the slope.

The formula for slope is y1-y2/x1-x2

In and ordered pair the first value is the (x) and the second is the (y).

(x, y)

We take the (y) of one of the given points and subtract the (y) of the second given point, then divide it by the (x) of one of the given points and the (x) of the other given point.

5-(-1)/8-4

Simplify.

5-(-1) =5+1= 6

8-4=4

6/4 Simplify

3/2 is our slope.

Now we apply out new slope into our y=mx+b

y=3/2x+b

Now we need to find the (b) which is the y intercept.

To do this we need to use one of our given points, you can choose either but for this I'll use (4, -1).

In this ordered pair 4 is the (x) and -1 is the (y)

So replace (y) with -1 and (x) with 4

-1=3/2(4)+b

Now solve as usual.

-1=6+b

subtract 6 from each side

-7=b

b=-7

Put our (m) and (b) into our formula.

y=2/3x-7 is our equation.

Answer:

C. x = 8

Step-by-step explanation:

We know that x · x · x is equal to 512. We know it cannot be negative because then the 512 would be negative. -2 x -2 x -2 is -8. -2 x -2 is 4. We know it cannot be B x = -6 or D. x = -8.

Let's multiply 6 x 6 x 6.

36 x 6 = 216.

Let's multiply 8 x 8 x 8.

64 x 8 = 512

The answer would be C. x = 8.

y= 3/2x+ 360

Step-by-step explanation:

3/2 is the slope

360 is the b (y intercept)

Answer:

slope m = -60

equation y = -60x + 360

Step-by-step explanation:

to find slope use two points given

(x1, y1) = (6, 0)

(x2, y2) = (0, 360)

m = (360-0) / (0-6) = -60

equation y = mx + b

b is the y intercept at (0,360), b= 360

y = -60x + 360

A factory needs to produce 1,800 jars of peanut butter on a certain day.
They start production at 8:30 A.M. By 10:30 A.M., they have produced 600 jars of peanut butter. At what time will they complete the total number of jars that they need to produce?

Answers

Answer:

2:30 am

Step-by-step explanation:

There is a 2 hour gap in between 8:30 and 10:30 and since they only made 600 jars throughout those 2 hrs you can divide 600 by 2 so you can fins out how many jars they make every hr.

Or you can multiply 600 and 2 to find out how much they make within the next 2 hrs.

600 * 2 = 1200

1200 jars were made at 12:30

1200 * 2 = 1800

1800 jars were made at 2:30

There are two hours between 8:30 A.M. and 10:30 A.M. If they make 600 jars of peanut butter per two hours, then they will make 300 jars per hour. 1800 divided by 6 is 300, so they need six hours to make 1800 jars of peanut butter. So, if they begin production at 8:30 A.M., the factory will have produced 1800 at 4:30 P.M.

Let the measure of the other interior angle = M

The exterior angle is equal to the sum of the interior angles in a given triangle.

An exterior angle of a triangle has a measure of 80°, and one of the remote interior angles has a measure of 20°.

This means,

M + 20 = 80

Solve for M.

M + 20 = 80

Subtract 20 on both sides.

M = 80 - 20

M = 60

Thus,

The measure of the other remote interior angle is 60°.
