D. 56

Answer:

I think it's 7r-14

Step-by-step explanation:

It says "eliminate redundant parentheses"

Then "subtract the numbers"

And then the solution should be what I put as the answer

Answer:

5(7r - 2) - 12 = 35r - 22

Step-by-step explanation:

First you want to do the mailman (it's what I called it in school) so take 5*7r which is 35r and do 5*(-)2 which is -10. So far the equation looks like this:

35r - 10 - 12

So now you subtract -10 from -12 and since they are both negative numbers it will be -22. So it's 35r - 22

5(7r - 2) - 12

35r - 10 - 12

35r - 22

I hope this helped!!

Answer:

6 to 4

Step-by-step explanation:

The amount of water is 6 and the amount of flour is 4 therefor there is 6 to 4 cups of water.

Answer:

Approximately 38 cube inches of wax.

Step-by-step explanation:

The candle can be assumed to have the shape of a cylinder, so that;

volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

where: r is the radius and h the height of the cylinder.

Thus,

volume of each candle =  [tex]\pi[/tex][tex]r^{2}[/tex]h

But radius is 1 inch and height is 4 inches, then;

volume of each candle = [tex]\frac{22}{7}[/tex] x [tex]1^{2}[/tex] x 4

                                      = [tex]\frac{22}{7}[/tex] x 1 x 4

                                      = 12.5714

volume of each candle = 12.6 cube inches.

Therefore, for the three candles;

volume of the three candles = 3 x 12.5714

                                                = 37.7142

volume of the three candles = 37.7142 cube inches

The amount of wax required for the three candles is approximately 38 cube inches.

Answer:

$127.68

Step-by-step explanation:

Rate= 6.4%

Principal= $120

Time = 1 year

Required

The final amount A

Step two

A=P(1+rt)

substitute

A=120(1+0.064*1)

A=120(1.064)

A=120*1.064

A=$127.68

Hence the final amount is $127.68

Answer: 0.32768

Step-by-step explanation:

Let x= number of employees have college degree.

Binomial probability formula :

[tex]P(X=x)=\ ^nC_xp^x(1-p)^{n-x}[/tex] , where p probability of success in each trial , n= sample size, x= number of successes.

As per given , p =0.80 , n= 5 , x=5

[tex]P(x=5)=\ ^5C_5(0.8)^5(0.2)^{0}= (1)(0..8)^5(1)\ \ \ [\ ^nC_n=1]\\\\= 0.32768[/tex]

Hence , the probability that all 5 will have college degrees = 0.32768

The other person was almost right, but Edge rounds it.

Step-by-step explanation:

Hey there!

Given;

4(X+1) -3 and 4x+1.

No, they are equivalent.

Reason:

Solving 1st expression.

4(x+1) = 4x + 4 - 3

Now, next expression is: 4x+1.

So, 4x + 4 = 4x+1

So, they are equivalent to eachother.

Hope it helps...

is 4(x+1) - 3 and 4x + 1 equivalent and why?

Step-by-step explanation:

Hey there!

Given;

4(X+1) -3 and 4x+1.

No, they are equivalent.

Reason:

Solving 1st expression.

4(x+1) = 4x + 4 - 3

Now, next expression is: 4x+1.

So, 4x + 4 = 4x+1

So, they are equivalent to eachother.

Answer:

[tex]5x^{-10}z^{10[/tex]

Step-by-step explanation:

Given

[tex]\frac{15x^{-3}z^5}{3x^7z^{-5}}[/tex]

Required

Evaluate

[tex]\frac{15x^{-3}z^5}{3x^7z^{-5}}[/tex]

Start by dividing 15 by 3

[tex]\frac{5x^{-3}z^5}{x^7z^{-5}}[/tex]

Apply the following law of indices on indices x and z

[tex]\frac{a^m}{a^n} = a^{m-n[/tex]

So, the expression becomes:

[tex]5x^{-3-7}z^{5-(-5)[/tex]

[tex]5x^{-3-7}z^{5+5[/tex]

[tex]5x^{-10}z^{10[/tex]
