Answer:

2, 4, 5, 6, 7, 8

Step-by-step explanation:

The number 2 is not a factor of 9. The correct option is D.

A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor in mathematics.

The given number is 9.

To find the factor of 9:

Number m that evenly divides another number 9.

In simple words, when we divide the number 9 by a number m.

We should get a whole number.

From the options,

9/1 = 9

9/3 = 3

9/9 = 1

9/2 = 4.5

Therefore, the number 2 is not the factor of 9.

[tex]V(x)=4x^3-112x^2+720x[/tex]

Step-by-step explanation:

[tex](36-2x)(20-2x)x[/tex]

[tex](720-72x-40x+4x^2)x[/tex]

[tex](4x^2-112x+720)x[/tex]

Therefore, the resulting volume would be [tex]V(x)=4x^3-112x^2+720x[/tex]

Answer:

x = 20°

Step-by-step explanation:

OA = OB

so 140°+x°+x° = 180°

140+2x = 180

2x = 40

x = 20°

Answer:

36n + 18

Step-by-step explanation:

6 * 6n = 36n

6 * 3 = 18

36n + 18 = 36n + 18

Answer:

36n+18

Step-by-step explanation:

6(6n+3)

(6×6n)+(6×3)

36n+18

But if you want it simplifed, you can divide both 36n and 18 by 18 and you will be left with 2n+1

The number of ways Molly can arrange the tomato plants in an array is 27,907,200 ways

Find the image attached. From the figure, we can see that there are 6 rows in the array.

If there are 20 tomato plants, the ways Molly can arrange the tomato plants in an array is expressed according to the permutation formula:

20P6 = 20!/(20-6)!

20P6 = 20!/14!

20P6 =  20 * 19 * 18 * 17 * 16 * 15

20P6 = 27,907,200

Hence the number of ways Molly can arrange the tomato plants in an array is 27,907,200 ways

Answer:

Step-by-step explanation:

Let q represent the number of quarters, and d represent the number of dimes.

  0.25q +0.10d = 4.20 . . . . . the value of the coins

  q = 2d . . . . . . . . . . . . . . . the relation between the numbers of coins.

__

Additional comment

Using substitution, the equation simplifies to ...

  0.60d = 4.20

  d = 7

  q = 14

Note that the coins can be grouped into groups of 2 quarters and 1 dime. The value of the group is $0.60, and the number of dimes is equal to the number of groups. Thinking about the problem in this way gets you immediately to the single equation 0.60d = 4.20.

Answer:

Step-by-step explanation:

Use the slope formula to solve this problem. Slope, usually called m, is the change in y-values over the change in x-values.

m = (y2 - y1)/(x2 -x1)

It actually doesn't matter which point is the first point and which point is the second point. But you must be consistent.

So fill in -3/2 for the m

Let your (6, b) be your (x1, y1)

Let (-2, 4) be your (x2, y2)

So, the numbers fill into the formula like so:

-3/2 = (4 - b)/ (-2 - 6)

-3/2 = (4 - b)/(-8)

Multiply -8 on both sides of the equation.

(-8)(-3/2) = 4 - b

12 = 4 - b

Subtract 4 from both sides.

Don't lose the negative in front of the b

8 = -b

Multiply or divide by -1 on both sides.

-8 = b This is the answer.

**note: Its kinda crummy to use b in this equation, because b has a special meaning when you are working with linear equations. They should have given you a different variable. b usually stands for the y-intercept but in this problem it doesn't, it's just a variable representing an unknown value.

Answer:

64 ft

Step-by-step explanation:

A square has to be equal on all 4 sides for it to be considered a square. Considering that it is 8 feet on one side it would be 8 feet on all the others as well. From there you multiply 8*8 and receive the solution of 84 feet for the area of the garden.

First, subtract 60 from both sides of the equation:

-15x + 60 (-60) < 105 (-60)

-15x < 45

Next, divide -15 from both sides of the equation. Note that when you multiply or divide a negative number, you must flip the sign:

(-15x)/-15 < (45)/-15

x < 45/(-15)

x > -3

[tex]x > -3[/tex] is your answer.

Geometric Sequence is being multiplied by factor of 3.

Step-by-step explanation:

to round 4.645 to the nearest whole number consider the tenths’ value of 4.645, which is 6 and equal or more than 5. Therefore, we have to round up: the whole number part of 4.645, 4, increases by 1 to 5, and the decimal point and all digits (.645) are removed.

4.645 rounded to the nearest whole number = 5
