120º is 1/3 of a complete revolution of 360º. So the area of this sector should be 1/3 the area of the complete circle.

A circle with radius 9 has area 9^2 π = 81π.

So the sector has area 81π/3.

Put another way: The area A of a circular sector and its central angle θ (in degrees) occur in the same ratio as the area of the entire circle with radius r according to

A / θ º = (π r ^2) / 360º

==>  A = π/360 θ r ^2

In this case, r = 9 and θ = 120º, so

A = π/360 * 120 * 81 = 81π/3

Step-by-step explanation:

Consider the diagram below for the number line.

From the number line it is clear that the above statement is true.

From the number line it is clear that the above statement is true.

The value of √2 is 1.414. This value is less than 1.5.

So, the above statement is false.

From the number line it is clear that the above statement is true.

The value of √3 is 1.732. The difference between √2 and √3 is, 0.318.

Thus, the above statement is false.

The value of √3 is 1.732. The difference between √2 and √3 is, 0.318.

Implying, √3 = √2 + 0.318.

⇒√3 = √2 + 0.3

Thus, the above statement is true.

The correct answer is option B)  –0.19.

A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another. In positively correlated variables, the value increases or decreases in tandem.

A relationship between two variables, x, and y, in which the change in the value of one variable is exactly proportional to the change in the value of the other. That is, knowing the value of one variable exactly predicts the value of the other variable (i.e., rxy = 1.0).

Step-by-step explanation:

Answer:

A is 29 miles and B is 18 miles

Step-by-step explanation:

Set up 2 equations involving A and B and solve simultaneously, that is

5A + 2B = 181 → (1)

2A + 3B = 112 → (2)

Multiply (1) by 3 and (2) by - 2 to eliminate B

15A + 6B = 543 → (3)

- 4A - 6B = - 224 → (4)

Add (3) and (4) term by term to eliminate B

(15A - 4A) + (6B - 6B) = 543 - 224, that is

11A = 319 ( divide both sides by 11 )

A = 29

Substitute A = 29 into either of the 2 equations and solve for B

Substituting into (1)

5(29) + 2B = 181

145 + 2B = 181 ( subtract 145 from both sides )

2B = 36 ( divide both sides by 2 )

B = 18

Thus

Route A is 29 miles long and Route B is 18 miles long.

The options A and C represent the same line as the given equation.

A: 3y = - 4x + 40

C: 4x + 3y = 5

To verify which equations represent the same line as the given equation y - 11 = -4 (x + 7), we can first convert the given equation into slope-intercept form y = mx + b, where m is the slope and b is the y-intercept.

Given equation:

y - 11 = -4 (x + 7)

Expanding and rearranging:

y - 11 = -4x - 28

y = -4x - 28 + 11

y = -4x - 17

Now, let's compare this equation with the options:

A. 3y = -4x + 40

To convert it to slope-intercept form:

y = [tex]-\frac{4}{3}x + \frac{40}{3}[/tex]

B. 4x + y = 21

To convert it to slope-intercept form:

y = -4x + 21

C. 4x + 3y = 5

To convert it to slope-intercept form:

3y = -4x + 5

y = [tex]-\frac{4}{3}x + \frac{5}{3}[/tex]

D. -4x + 3y = 17  

To convert it to slope-intercept form:

3y = 4x + 17

y = [tex]\frac{4}{3}x + \frac{17}{3}[/tex]

Comparing all the equations with the original equation y = -4x - 17, we find that options A and C have the same slope-intercept form as the original equation.

The question is:

A line is drawn through (-7, 11) and (8, –9). The equation y - 11 = - 4(x + 7) is written to represent the line. Which equations also represent the line? Check all that apply.

A. 3y = - 4x + 40

B. 4x + y = 21

C. 4x + 3y = 5

D. -4x + 3y = 17

The only equation that represents the same line as the given equation y - 11 = - 4(x + 7) is -4x + 3y = 17, as it has the same slope and y-intercept when simplified.

To determine which equations also represent the line through the points (-7, 11) and (8, -9), we must ensure they have the same slope and y-intercept as the given line equation y - 11 = - 4(x + 7). First, we simplify the given equation to the slope-intercept form (y = mx + b):

y = -4x - 28 + 11

y = -4x - 17

The slope (m) is -4, and the y-intercept (b) is -17. Now, let's compare the other equations:

3y = - 4x + 40

4x + y = 21

4x + 3y = 5

-4x + 3y = 17

The only equation that has both the slope and y-intercept identical to the given line's equation after simplification is -4x + 3y = 17.

Answer:

225

Step-by-step explanation:

60 divided by 3/8 is 225

Final answer:

Mikayla spent 3/8 of her savings which was $60, so by setting up a proportion and solving it, we find that she had $160 in her savings before she went to the store.

Explanation:

Mikayla spent 3/8 of her savings which was $60. To find out how much money she had before going to the store, we can use a simple proportion. We know that the part Mikayla spent ($60) corresponds to 3/8 of her total savings. To find the whole, we set up a proportion:

3/8 = $60/Total Savings

Now, we will solve for the 'Total Savings' by multiplying both sides of the equation by the reciprocal of 3/8, which is 8/3:

Total Savings = $60 × (8/3)

Total Savings = $60 × 8 ÷ 3

Total Savings = $480 ÷ 3

Total Savings = $160

Therefore, Mikayla had $160 in her savings before she went to the store.

Answer: 0.24

Final answer:

To maximize profit, a monopolist sets the price at the highest level consumers are willing to pay for the profit-maximizing quantity of output, found where the marginal revenue curve intersects the demand curve. This ensures significant profits are realized, as seen when comparing total revenues and total costs.

Explanation:

Maximizing Profit Through Price Setting

To determine the price to maximize profit in a monopoly, we need to understand the relationship between the monopolist's pricing strategy and their profit-maximizing output level. According to the model provided, we know that the profit-maximizing price is not directly given but can be deduced by knowing that x represents the change in price from an initial price, often the base price of $22 in a given scenario. To find the optimal price, a monopolist will look at the profit-maximizing quantity of output first, which is found at the point where marginal revenue equals marginal cost.

Once they have that quantity, they will determine the price consumers are willing to pay by extending a line up from this quantity to intersect the demand curve on a graph (referred to as the 'dotted line'). The intersection on the demand curve represents the highest price consumers are willing to pay for that quantity of goods, which is the optimal price. For example, if the model shows 5 units as the profit-maximizing quantity and the average cost for producing the units is $330, then the firm would charge $800 per unit, since it's the market Willingness to pay as shown in the demand curve, leading to total revenues of 5 x $800 = $4000, with profits calculated as $4000 - (5 x $330 = $1650) = $2350. A monopolist can sustain such profits due to barriers that protect its market from entry by competitors.

Therefore, the best price to charge in order to maximize profit is one that corresponds to this profit-maximizing output on the firm's demand curve, which is above the average cost and allows the firm to realize significant profits.
