Answer:

Step-by-step explanation: Here's your answer 50√3 m.

The function that represent the company's profit is (2.52x - 700).

As per the known formula, Profit = Revenue - Cost

Now keeping the functions of revenue and cost to find the function of profit.

Profit = 2.9x - (0.38x + 700)

Performing subtraction on Right Hand Side of the equation to find the profit of company

Profit = 2.9x - 0.38x - 700

Performing subtraction on Right Hand Side of the equation to find the profit of company

Profit = 2.52x - 700

Thus, the the profit of company will be represented by the function 2.52x - 700.

The expression 0.5 (x + 3) written as a sum is 0.5x + 1.5

From the question, we have the following parameters that can be used in our computation:

0.5 ( x +3)

Write the expression properly

So, we have the following representation

0.5 (x + 3)

Express the brackets as products

So, we have the following representation

0.5 (x + 3) = 0.5 * (x + 3)

Open the brackets using products i.e. distributive property

So, we have the following representation

0.5 (x + 3) = 0.5 * x + 0.5 * 3

Evaluate the products

So, we have the following representation

0.5 (x + 3) = 0.5x + 1.5

Answer:

The inequality that represents how many miles Henry can drive the car is "m <= 550.5". This inequality can be derived by first calculating the total cost of renting the car for 2 days at $39.90 per day and $0.20 per mile. This gives us a total cost of $79.80 for the rental plus $0.20 per mile for the number of miles Henry drives. Since Henry has $150.00 to spend, we can set up the following inequality to represent the maximum number of miles he can drive:

150.00 >= 79.80 + 0.20m

We can then solve for m by subtracting 79.80 from both sides of the inequality and dividing both sides by 0.20, which gives us:

m <= 550.5

Therefore, the inequality that represents how many miles Henry can drive the car is "m <= 550.5". This inequality states that Henry can drive the car for a maximum of 550.5 miles.

By using some exponent properties, we will see that the equivalent expression to √(x⁵*y⁶) is:

x²*y³*√x

So the correct option is the first one.

Here we need to remember 3 properties about exponents that we will need to use.

These are:

√x = x¹´²

Also remember that:

(xⁿ)ᵃ = xⁿ*ᵃ

And that:

√(a*b) = √a*√b

Well, our expression is:

√(x⁵*y⁶)

We can rewrite this as:

√x⁵*√y⁶

And using the first and second properties we can rewrite.

√x⁵ = x⁵´² = x⁴´²*x¹´² = x²*√x

√y⁶ = y⁶´² = y³

Replacing all that we get:

√(x⁵*y⁶) =  x²*y³*√x

What are Parallel Lines Cut by Transversal?

Straight, equally spaced lines that never cross each other and are on the same plane are called parallel lines. The angles that are created when any two parallel lines are intersected by a line (referred to as the transversal) have a relationship. Corresponding angles, Alternate Interior Angles, Alternate Exterior Angles, and Consecutive Interior Angles are some of the several pairs of angles that are created at this intersection.

Corresponding angles

When two parallel lines are intersected by a transversal, the corresponding angles have the same relative position

Alternate Interior Angles

Alternate interior angles are formed on the inside of two parallel lines which are intersected by a transversal.

Alternate Exterior Angles

The pairs of angles formed on either side of a transversal that divides two parallel lines are known as alternate exterior angles.

Consecutive Interior Angles

When two parallel lines are cut by a transversal, the pairs of angles formed on the inside of one side of the transversal are called consecutive interior angles or co-interior angles.

Given data ,

From the figure , we can see that

The angles 5 , 6 , 7 and 8 are all on the straight line t

The angles 1 , 2 , 3 and 4 are all on the straight line n

The line m is the transversal line

Now ,

From the theorem of angles on a parallel lines , we get

Alternate angles are equal

So , 2 = 8 and 3 = 5

Now ,

Angle 2 and Angle 8 = Alternate Interior Angles

Angle 3 and Angle 5 = Alternate Exterior Angles

Corresponding angles are equal

So , 1 = 5 and 2 = 6

Answer:

w + 18 = 22

Step-by-step explanation:

HC = 18 lb

HC + GD = 22 lb

GD + HC = 22

GD + 18 = 22

w + 18 = 22

Answer:

A. Here are three more equations that are true based on the information you provided:

1. 3w + 2 = 2w + 6

2. 5w - 6 = 4w - 8

3. 7w - 5 = 6w - 7

B. To find the value of 2w, we need to first solve for w in the original equation 7w + 4 = 5w + 12. We can do this by subtracting 5w from both sides of the equation, which gives us 2w + 4 = 12. Then we can subtract 4 from both sides to get 2w = 8. Therefore, the value of 2w is 8.

C. To find the value of w, we can divide both sides of the equation 2w = 8 by 2, which gives us w = 4. Therefore, the value of w is 4.

The probability that A will have more heads than B is 1/2, when A and B are playing a game where a has n + 1 coins, b has n coins, and they each flip all of their coins.

Given, a and b are playing a game where a has n + 1 coins, b has n coins, and they each flip all of their coins.

we have to find the probability that a will have more heads than b.

Now, p1  = "probability that A obtains more heads than B.".

p2 = "probability that B obtains more heads than A.".

p3 = "probability that A obtains as many heads as B.".

Such that p1 + p2 + p3 = 1.

Since, both flips n coins, A wins with the same probability as B.

p1 = p2

Now, A flips and extra coin.

½ of the time it gives tails and doesn't contribute, but ½ of the time is gives heads meaning that A now wins if they before had equal number of heads.

p1+1/2(1 − p1 − p2)=1/2.

Hence, the probability that A will have more heads than B is 1/2, when A and B are playing a game where a has n + 1 coins, b has n coins, and they each flip all of their coins.

Answer:

2x² + 7x - 15.

Step-by-step explanation:

The product when x- 5 is multiplied by 2x + 3 is 2x² +7x - 15. To find the product, we need to use the distributive property. This states that for any two expressions, a and b, and a constant, c, we have the following:

c * (a + b) = c * a + c * b

We can use this property to expand the expression (x - 5)(2x + 3) as follows:

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

               = 2x^2 + 3x + (-10x) + (-15)

               = 2x^2 + 7x - 15

Therefore, the product of the expression (x - 5)(2x + 3) is 2x^2 + 7x - 15, which matches the answer choice 2x² + 7x - 15.

The equation of the line is y = 0.4x - 793.65 and the minimum wage is $18.35

The equation of a line can be formed with the help of the slope of the line and a point on the line. Let us understand more about the slope of the line and the needed point on the line, to better understand the formation of the equation of a line. The slope of the line is the inclination of the line with the positive x-axis and is expressed as a numeric integer, fraction, or the tangent of the angle it makes with the positive x-axis. The point refers to a point in the coordinate system with the x coordinate and the y coordinate.

a)

Taking two points from the table;

Using 1996 and 1997

The data are; (1996, 4.75), (1997, 5.15)

m = y₂ - y₁ / x₂ - x₁

m = 5.15 - 4.75 / 1997 - 1996

m = 0.4

The slope of the line is 0.4

Using the line equation;

y = mx + c

Taking one point, we can find y-intercept here

5.15 = 0.4(1997) + c

5.15 = 798.8 + c

c = 5.15 - 798.8

c = -793.65

The equation of the line is y = 0.4x - 793.65

b) The minimum wage in 2030

y = 0.4x - 793.65

y = 0.4(2030) - 793.65
