Answer:

  P = -0.00047x^2 +40x -130,000

Step-by-step explanation:

Profit is found by subtracting the company's costs from its revenue.

  P = R - C

  P = (50x -0.00047x^2) -(10x + 130,000)

  P = -0.00047x^2 +40x -130,000

Answer:

x=0

Step-by-step explanation:

Key skills needed: Proportions, Cross multiplication, One variable Equations, Multiplication

1) Since this is a proportion, we need to cross multiply. A proportion is just 2 fractions equal to each other in this format.

---> Cross multiplication is when you multiply the first fraction's numerator by the second fraction's denominator, and you multiply the first fraction's denominator by the second fraction's numerator.

---> You set these products equal to each other.

2) So if we cross multiply it would be: 3(3x+5) = 5(3-2x)

---> If you multiply everything out, it would be --> 9x + 15 = 15 - 10x

3) Move the x terms to one side and the numbers to the other side

--->  9x + 10x = 15-15

4)  Combine like terms (9x+ 10x= 19x) (15-15=0) 19x = 0

5) Divide by 19 and x=0.

Hope you understood and have a nice day!! :D

Answer:

Rational

Step-by-step explanation:

The number comes to a stop (doesn't keep going), so it would be rational.

Answer:

3.5 is a rational number

Step-by-step explanation:

Irrational numbers are numbers that keep on going forever like pi (π). Or numbers like these.....[tex]\sqrt{72} , \sqrt{2} , \sqrt{\frac{8}{23} }[/tex]

Those are non-recurring numbers and non-terminating decimal numbers

Rational numbers are numbers that can be written as a simple fraction or ration, and 3.5 can be written as a simple fraction...

7/2 = improper fraction (3.5 as a decimal)

3 1/2 = mixed number (3.5 as a decimal)

Answer:

Step-by-step explanation:

Number of individuals = 4

Cost of dozen donuts with transport = $17.45 + $1.25

= $18.7

Since there are 12 pieces in a dozen pack of donuts, then the amount of each donut is:

= $18.7/ 12

= $1.56

So, if four people share a dozen donut, each person will have:

= 12/4

= 3 donuts each

and the price each person will pay for the three donuts will be:

= $1.56 × 3

= $4.68

- linear pairs are supplementary, meaning they add up to 180°

5x + 9 + 3x + 11 = 180

8x + 20 = 180

8x = 160

x = 20

- now plug in.

angle 1: 5(20) + 9 = 100 + 9 = 109°

angle 2: 3(20) + 11 = 60 + 11 = 71°

Answer:

(h,k) shows the coordintes of the turning point.

Answer:

coordinates of the vertex

Step-by-step explanation:

The equation of a parabola in vertex form is

f(x) = a(x - h)² + k

where (h, k ) are the coordinates of the vertex and a is a multiplier

f(x) = 3(x - h)² + k ← is in vertex form

with vertex = (h, k )

Step-by-step explanation:

The given sheet of paper is folded horizontally, thus a pattern with respect to the fold is formed inside the paper. This pattern would in the form of two lines crossing each other at right angles.

To illustrate a reflection over the fold of the card, the pattern in option D could be used as the center of the invitation.

Therefore, the correct option is D.

Answer:

The formula for the area of a circle is A = π r2, where r is the length of the radius of a circle. We can use our knowledge that a diameter is made up of two radii to understand that r = d/2. With this knowledge, you can rewrite the formula for the area of a circle as A = π (d/2)2.

30x-16=14  Equation/Question

Step 2

30x-16=14 Simplify

30x-16=14

Step 3

30x-16=14  Add 16 to sides

30x=30

Step 4

30x=30  Divide sides by 30

answer

x=1

Hope this helps

Step-by-step explanation: To solve for X, we'll need to move all terms that don't contain X to the right and solve.

1. Add 16 to both sides

30x - 16 + 16 = 14 + 16

30x = 30

2. Divide both sides by 30

[tex]\frac{30x}{30} =\frac{30}{30}[/tex]

Therefore, your answer is 1.

Answer:

[tex]-12[/tex]

Step-by-step explanation:

Given that:

[tex]a=\frac{1}{4} \\b=6[/tex]

To evaluate the expression [tex]-8ab[/tex], we must simply substitute the given values into the expression, and solve:

[tex]-8(\frac{1}{4} )(6)[/tex]

Multiply [tex]-8[/tex] and 6:

[tex]-48*\frac{1}{4}[/tex]
