Answer:

[tex]\frac{5}{1}[/tex]

Step-by-step explanation:

10:2 would be written as [tex]\frac{10}{2}[/tex] in fraction form.

We can simplify this fraction to 5 to 1.

[tex]\frac{10}{2}=\frac{10/2}{2/2}=\frac{5}{1}[/tex]

Answer:

n = 10

Step-by-step explanation:

=> 2(4 + n) = 28

=> 2(4) + 2(n) = 28

=> 8 + 2n = 28

=> 2n = 28 - 8

=> 2n = 20

=> n = 20/2

=> n = 10

Answer:

n = 10

Step-by-step explanation:

2(4 + n) = 28

Distribute:

(8 + 2n) = 28

Eliminate Parenthesis:

8 + 2n = 28

Cancel Out:

2n = 20

Divide:

n = 10

Answer: Either 8 dimes and 6 nickles, or 4 quarters and 10 pennies. Both combinations add up to $1.10.

Have a nice day

The 14 coins can be:

- 8 dimes and 6 nickels

Or

- 10 pennies and 4 quarters

Given,

14 coins make up $1.10

We need to find what are the 14 coins.

We have,

100 pennies = $1

20 nickels = $1

10 dimes = $1

4 quarters = $1

Find the coins that are worth $1.10

We have

10 dimes = $1

So,

1 dime = $0.10

8 dimes = $0.80 _____(1)

20 nickels = $1

So,

1 nickels = $0.05

6 nickels = $0.30 _____(2)

100 pennies = $1

10 pennies = $0.1 _____(3)

4 quarters = $1 ______(4)

From (1) and (2)

8 dimes + 6 nickels = $0.80 + $0.30

14 coins = $1.10

From (3) and (4)

10 pennies + 4 quarters = $0.1 + $1

14 coins = $1.10

Thus the 14 coins can be:

- 8 dimes and 6 nickels

- 10 pennies and 4 quarters

Answer: 4x² + x - 2

Step-by-step explanation: First distribute the -2x into (1-3x) which = -2x + 6x²

Now let's work on the second part:

Distributing (2x + 3) to (3x - 2) = 6x² - 4x + 9x - 6. Combining like terms: 6x² - 4x + 9x - 6 --> 6x² + 5x - 6. Now let's combine the like factors of our two equations which equals

12x² + 3x - 6. Now reduce by dividing by 3 which gives us the final answer of:

4x² + x - 2.

Answer:

The volume of the rectangular prism is 512 inches³

Step-by-step explanation:

Any cube has 6 square faces

Area of any square = L × L, where L is a length of each side

The volume of the cube = L × L × L

∵ The area of the top face of a cube = 16 inches²

→ Find which number multiply by itself = 16

∵ 16 = L × L

∵ 16 = 4 × 4

∴ L = 4 inches

Let us find the volume of 1 cube

∵ The volume of the cube = L × L × L

∵ L = 4 inches

∴ The volume of each cube = 4 × 4 × 4

∴ The volume of each cube = 64 inches³

∵ We will use 8 of this cube to make a rectangular prism

→ That means the volume of the rectangular prism is 8 times

   the volume of 1 cube

∴ The volume of the prism = 8 × volume of 1 cube

∵ The volume of each cube = 64 inches³

∴ The volume of the prism = 8 × 64

∴ The volume of the prism = 512 inches³

The volume of the rectangular prism is 512 inches³

Answer:

0.8

Step-by-step explanation:

From the given information:

The population mean = 60

The standard deviation = 8

The sample size = 100

The sample distribution which follows a normal distribution is the set of values ​​taken by this statistic on each sample from the same population.

The standard deviation of the comparison distribution's = [tex]\dfrac{\sigma}{\sqrt{n}}[/tex]

The standard deviation of the comparison distribution's = [tex]\dfrac{8}{\sqrt{100}}[/tex]

The standard deviation of the comparison distribution's = 8/10

The standard deviation of the comparison distribution's = 0.8

Answer:

X= -7

Step-by-step explanation:

When you get X to one side and simplify you get -7

8x + 12 = 4 x - 16

Subtract 12 from both sides

8x = 4x - 28

Subtract 4x from both sides

4x = -28

Divide both sides by 4 to get rid of the coefficient so we know what x alone is equal to, instead of what we have currently which shows what 4 x's equals

x = -28/4

x = -7

1x = - 7

One x is equal to - 7 units.
