Answer:

The answer is c=9

Step-by-step explanation:

-4(2c-11)=-28

-8c+44=-28

-8c+44-44=-28-44

-8c=-72

To find C divide both sides by -8

-8c/-8=-72/-8

Answer:

Step-by-step explanation: We have been given 4 expressions. We are asked to choose the expression that represents sum of cubes.

We know that sum of cubes is in form .

We can see that 1st and 2nd option has a negative sign. Therefore, these options cannot be sum of cubes.

Let us check 3rd and 4th options one by one.

We can rewrite our expression by writing terms as cubes:

Therefore, expression  is a sum of cubes.

In 4th expression, we can see that . We cannot represent it as a cube. Similarly, we cannot represent  as a cube. Therefore, 4th expression is not correct.

Answer:

x = 5

TE = 13

Step-by-step explanation:

Since GT is the median, then 2*(FT) = FE.

FE = 5x + 1

FT = 3x - 2

Therefore:

2*(3x - 2) = 5x + 1 (substitution)

6x - 4 = 5x + 1

Collect like terms

6x - 5x = 4 + 1

x = 5

TE = ½*(FE)

TE = ½*(5x + 1)

Plug in the value of x

TE = ½*(5(5) + 1)

TE = ½(25 + 1) = ½(26)

TE = 13

Answer:

0.002M

Step-by-step explanation:

2.7= -log(H^+)

-2.7=log(H^+)

10^-2.7 M=H^+

0.0002M=H^+

The stomach has an acidic fluid that is an important part of the digestive juices. The pH of 2.7 in the stomach is close to a 0.002M concentration of hydrogen.

pH measures the concentration of the hydronium and the hydrogen ions in the solution. pH is calculated as:

pH = -log (H⁺)

Here, pH = 2.7

Substituting values:

2.7 = -log (H⁺)

-2.7 = log (H⁺)

H⁺ = 10⁻²⁷ M

H⁺ = 0.0002M

Therefore, 0.002M is the concentration of hydrogen.

Answer:

Ryan has 10 pennies and 13 nickels.

Step-by-step explanation:

Let the number of pennies be p and the number of nickels be n.

We have two unknowns, the number of pennies and the number of nickels, so we need two equations. One equation will deal with the value of the coins. The other equation will deal with the number of coins.

Value of coins:

1 penny is worth $0.01; p pennies are worth 0.01p.

1 nickel is worth $0.05; n nickels are worth 0.05n.

The total amount the coins are worth is

0.01p + 0.05n

The coins are worth $0.75, so we have our first equation.

0.01p + 0.05n = 0.75       Equation 1

Number of coins:

He has p pennies.

The number of nickels is 3 more than the number of pennies.

Since the number of pennies is p, then the number of nickels is p + 3.

That gives us our second equation.

n = p + 3        Equation 2

System of equations:

Now we have a system of two equations in two unknowns:

0.01p + 0.05n = 0.75

n = p + 3

Since the second equation is already solved for n, we can use the substitution method.

Replace n in the first equation with p + 3.

0.01p + 0.05n = 0.75

0.01p + 0.05(p + 3) = 0.75

Distribute the 0.05

0.01p + 0.05p + 0.15 = 0.75

Combine like terms on the left side.

0.06p + 0.15 = 0.75

Subtract 0.15 from both sides.

0.06p = 0.6

Divide both sides by 0.06.

p = 0.6/0.06

p = 10

Now we substitute 10 for p in the second equation to find the value of n.

n = p + 3

n = 10 + 3

n = 13

He has 10 pennies and 13 nickels.

Check:

A) 13 - 10 = 3 He does have 3 more nickels than pennies.

B) $0.01(10) + $0.05(13) = $0.10 + $0.65 = $0.75

The number of coins and the value of the coins both check out, so our answer is correct.

Answer: Ryan has 10 pennies and 13 nickels.

Answer:

120 ways

Step-by-step explanation:

This is a pretty straightforward question. We are asked how many ways can 5 printers be displayed on one shelf. We use the formula of factorial in getting the number of ways, i.e

n! = n * (n-1) * ..... 1, in the question given, our n = 5, so if we plug it in, we get

n! = 5 * (5-1) * (4-1) * (3-1) * (2-1) * 1

n! = 5 * 4 * 3 * 2 * 1

n! = 120.

Thus, there are 120 different ways to display the five types of laser printer on a shelf.
