Answer:

The correct answer is 44

Step-by-step explanation:

6(8)-4

48-4

44

Answer:

f(8) = 44

Step-by-step explanation:

Plug in 8 for x. Then evaluate the expression.

f(x) = 6x - 4

Where you see x, substitute it with 8.

f(x) = 6x - 4

f(8) = 6(8) - 4

f(8) = 48 - 4

f(8) = 44

For this case we must indicate the graph corresponding to the following inequality:

[tex]y <\frac {3} {4} x + 2[/tex]

As it is observed that equality is not included, we can discard options C and D. We are left with the graphs of the dotted border line.

Graphic A:

We evaluate in the inequality the point [tex](0,0)[/tex]

[tex]0 <\frac {3} {4} (0) +2\\0 <2[/tex]

The inequality is met.

Thus, the inequality is represented in graph A.

Answer:

Option A

6:34 minutes Six hours thirty four minutes

Answer:

6 hours 34 minutes.

Step-by-step explanation:

12.00 pm - 7.59 am =  4 hours 1 minute.

2.33 pm - 12.00 pm =  2 hours 33 minutes.

Answer is 6 hours 34 minutes.

The markup percentage can be found by subtracting the cost price from the selling price, dividing by the cost price, and then multiplying by 100, resulting in a 30% markup.

The percent markup is calculated by finding the difference between the selling price and the cost price, then dividing that by the cost price and multiplying by 100.

Markup = (Selling Price - Cost Price) / Cost Price x 100

Markup = ($26 - $20) / $20 x 100

Markup = $6 / $20 x 100

Markup = 0.30 x 100

Markup = 30%

Answer:

Answer:

160°

Step-by-step explanation:

We can use the central angle theorem for this. It says that an angle inscribed in a circle (on the circumference) measured half of the arc it intercepts (by 2 points on the circumference of the circle).

that would mean that Angle KAW is half of measure of Arc KW. Thus we can write:

m∠A = 0.5 (arc KE + arc EW)

x+45 =0.5 (x+20+3x)

x+45 = 0.5(4x+20)

x+45 = 2x + 10

45 - 10 = 2x - x

Thus, x = 35

Since Arc KW = Arc KE + Arc EW and x = 35, we can say:

Arc KW = x + 20 + 3x = 35 + 20 + 3(35) = 160°

The value of the arc KW subtended from the center of circle O is 160°.

An equation is an expression that shows the relationship between two or more numbers and variables.

From the circle O:

m KW = m KE + m EW (angle addition postulate)

m KW = (x + 20) + (3x)

m KW = 4x + 20

m KW = 2m∠A (angle subtended from center)

4x + 20 = 2(x + 45)

x = 35

m KW = 4(35) + 20 = 160°

The value of the arc KW subtended from the center of circle O is 160°.

Answer:  40°

Step-by-step explanation:

There are 4 pink angles (labeled as "a") and each are the same measure.

There are 4 green angles (labeled as "b") and each measure 50°.

A circle is 360°

4a + 4b = 360

4a + 4(50) = 360

4a + 200 = 360

4a           = 160

 a           =  40

Answer:

(10, 1)

Step-by-step explanation:

-x = -y - 9 has already been solved for -x.  Multiply every term of this equation by -1 to obtain x = y + 9.  

Now substitute y + 9 for x in the first equation.  We get:

(y + 9) + y = 11, or, after combining the y terms, 2y = 2.

Solving for y, we get y = 1.

Subbing 1 for y in the first equation results in:  x + 1 = 11.

This yields x = 10.

Thus, the solution is (10, 1).

Answer:

(x+10) and (x-10)

Step-by-step explanation:

The volume of a rectangular box is defined as

Volume = width*height*length

In this case

Volume  = 6x^2-600  =  6*(x^2 - 100)

And we also know,

Volume  =  (6)*height*length

So,

6*(x^2 - 100) = (6)*height*length

This means that

height*length = (x^2 - 100)

height*length = (x+10)*(x-10)

The number of different color shirts Juan have to choose from is A = 3

The set formula is given in general as n(A∪B) = n(A) + n(B) - n(A⋂B), where A and B are two sets and n(A∪B) shows the number of elements present in either A or B and n(A⋂B) shows the number of elements present in both A and B.

Answer: [tex]\frac{x+5}{x+3}[/tex]

Step-by-step explanation:

The problem gives you the following expression:

[tex]\frac{x}{x+3}+\frac{3}{x+3}+\frac{2}{x+3}[/tex]

Therefore, to add the fractions with equal denominator, you must rewrite the denominator (x+3) and add the numerators of each one of the fractions.

Then, keeping the above on mind, you obtain the sum shown below (You must remember to add the like terms):

[tex]\frac{x+3+2}{x+3}=\frac{x+5}{x+3}[/tex]

Answer:

(x + 5)/(x + 3)

Step-by-step explanation:

I take all three fractions have a denominator of x + 3. If that is correct, then the question should be written as

x/(x + 3) + 3/(x + 3) + 2/(x + 3)

(x + 3 + 2)/ (x + 3)

(x + 5)/(x + 3)

That's the answer

Answer:

≈ 11 ounces

Step-by-step explanation:

(This is the easiest method I can explain, there is probably a simpler one)

We can make a system of equations (x = oz. of pure oil, y = oz. of mixture):

x + y = 100 oz. -> y = 100 - x

x + 0.0451y = 0.15(100) -> x + 0.0451y = 15

Using substitution, we get that x + 0.0451(100 - x) = 15.

This is equal to x + 4.51 - 0.0451x = 15.

Subtracting both sides by 4.51 and combining like terms gets us

0.9549x = 10.49.

Dividing both sides gives us about 11 ounces.

Final answer:

To obtain 100 ounces of a 15% oil-gas mixture from a 4.51% oil-gas solution, 10.49 ounces of pure oil should be added to the solution.

Explanation:

To solve the problem of how many ounces of pure oil should be mixed with an oil-gas solution that is 4.51% oil to get 100 ounces of an oil-gas mixture that is 15% oil, we can use a simple mixture equation. Let's denote the unknown quantity of pure oil to be added as x ounces.

First, we calculate the amount of oil already present in the 4.51% oil-gas mixture. If we have a total of 100 ounces, the existing oil in the mixture is 4.51% of this, that is 4.51 / 100 × 100 = 4.51 ounces.

Next, we know that the final mixture will have to be 15% oil. Therefore, in 100 ounces of this mixture, we will need 15% oil, which is 15 / 100 × 100 = 15 ounces of oil.

To find out how much pure oil to add, we subtract the amount of oil already present in the mixture from the total amount of oil needed. So, x + 4.51 = 15, which gives us x = 15 - 4.51 = 10.49 ounces of pure oil needed to be added.

To recreate a drawing on a new scale of 1 cm to 4 cm, simply multiply the original dimensions by the scale factor of 4.

If you are given a drawing and you want to recreate it on a new scale where 1 centimeter (cm) in the original equals to 4 centimeters in the new drawing, then you simply have to multiply the dimensions of the original by 4. Suppose the original drawing is 2 cm in length and 3 cm in width. Then the new length would be 2 cm * 4 = 8 cm and the new width would be 3 cm * 4 = 12 cm. Remember this is a general concept and can be applied to all dimensions of the drawing. It's a basic concept in proportion and scale factor.

Answer:

18c - 30d + 36

Step-by-step explanation:

you multiply the number outside to the numbers inside the parenthesis.

6 * 3c = 18c

6* -5d = -30d

6*6= 36

Answer:

18c - 30d + 36

Step-by-step explanation:

6(3c - 5d + 6) = ?

You first multiple 6 to 3c. This leaves you with 18c. Next, you multiply 6 to (-5d). Remember that it is a negative because it has a minus sign in front of the number, leaving you with -30d. Lastly, you have 6 times 6, which is 36. This leaves us with the equation of 18c - 30d + 36. I hope this helped.
