Answer:

87 ft/sec

Step-by-step explanation:

mile/hr *  hr/ seconds * feet/mile    =  feet per second

  ( see how  'mile' and 'hr' cancel out and you are left with feet/sec ?)

  Now, put in the numbers :

     59    *  1/3600  *  5280 = 86.533 = 87 ft/sec

The name of the segment inside the large triangle is called the: 3. angle bisector.

The word "bisect" means to divide into two equal halves. Therefore, an angle bisector can be defined as a line segment that divides the an angle in a triangle into two parts that are of the same angle measure.

The image shows a triangle which has a segment that divides a vertex angle into equal parts. Thus, the segment can be named as an angle bisector.

A perpendicular bisector divides a segment into two equal halves at right angle, while a midsegment joins the middle points of two sides of a triangle. The median also, is a segment that joins a vertex of a triangle to the midpoint of the side that is opposite the angle.

Therefore, we can state that the name of the segment is: 3. angle bisector.

Answer:

Square root of 169 is 13.

Step-by-step explanation:

13*13=169

Label the points A,B,C

Let's find the distance from A to B, aka find the length of segment AB.

We use the distance formula.

\(A = (x_1,y_1) = (1,2) \text{ and } B = (x_2, y_2) = (4,5)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-4)^2 + (2-5)^2}\\\\d = \sqrt{(-3)^2 + (-3)^2}\\\\d = \sqrt{9 + 9}\\\\d = \sqrt{18}\\\\d = \sqrt{9*2}\\\\d = \sqrt{9}*\sqrt{2}\\\\d = 3\sqrt{2}\\\\\)

Segment AB is exactly \(3\sqrt{2}\) units long.

Now let's find the distance from B to C

\(B = (x_1,y_1) = (4,5) \text{ and } C = (x_2, y_2) = (8,9)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(4-8)^2 + (5-9)^2}\\\\d = \sqrt{(-4)^2 + (-4)^2}\\\\d = \sqrt{16 + 16}\\\\d = \sqrt{32}\\\\d = \sqrt{16*2}\\\\d = \sqrt{16}*\sqrt{2}\\\\d = 4\sqrt{2}\\\\\)

Segment BC is exactly \(4\sqrt{2}\) units long.

Adding these segments gives

\(AB+BC = 3\sqrt{2}+4\sqrt{2} = 7\sqrt{2}\)

----------------------

Now if A,B,C are collinear then AB+BC should get the length of AC.

AB+BC = AC

Let's calculate the distance from A to C

\(A = (x_1,y_1) = (1,2) \text{ and } C = (x_2, y_2) = (8,9)\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(1-8)^2 + (2-9)^2}\\\\d = \sqrt{(-7)^2 + (-7)^2}\\\\d = \sqrt{49 + 49}\\\\d = \sqrt{98}\\\\d = \sqrt{49*2}\\\\d = \sqrt{49}*\sqrt{2}\\\\d = 7\sqrt{2}\\\\\)

AC is exactly \(7\sqrt{2}\) units long.

Therefore, we've shown that AB+BC = AC is a true equation.

This proves that A,B,C are collinear.

Graph D

Explanation:

Let m represent the number of members and n represent the number of non-members.

Last Sunday, the number of members with carts was at least twice the number of non-members.

The golf course charges a cart fee of $5 for members and $10 for non-members. The golf course collected at most $300 in cart fees.

Plotting the system of inequalities with m on the x-axis and n on the y-axis, we have the graph below:

The graph that represents the possible solution for the number of each kind of golfer is Graph D.

The easiest way to solve a system of equations is by using the substitution method.

The substitution method requires you to solve for one variable in one of the equations, substitute the answer into the other equation, and then solve for the remaining variable.

The easiest way to solve a system of equations is to use the substitution method. This method works by substituting one equation into the other to solve for one of the variables. Once the variable is found, it is then substituted back into the other equation to solve for the other variable. For example, if you have two equations: 3x + 2y = 5 and 4x - 2y = 6, you would solve the first equation for y and substitute the answer (y = (5 - 3x)/2) into the second equation. Then, you would solve the second equation for x (x = (6 + 2y)/4). Once you have the values for x and y, you can substitute them into either equation to check your answer.

Answer:

Width: \(10y^6\)

Length: 7y² + 3

Step-by-step explanation:

Step 1: Factor out 10

\(10(7y^8+3y^6)\)

Step 2: Factor out \(y^6\)

\(10y^6(7y^2+3)\)

According to the question, the width is the monomial (1 term), so that is equal to \(10y^6\). That means the distributed part would be the length (7y² + 3).

Answer: (2, -1)

Step-by-step explanation:

\(y=-3x^2 +12x-13\\\\y=-3(x^2 - 4x)-13\\\\y=-3\left(\left(x-2 \right)^{2}-4 \right)-13\\\\y=-3(x-2)^{2}+12-13\\\\y=-3(x-2)^2 - 1\)

So, the vertex is (2, -1).

Answer:

The mean absolute deviation of the following set of data is 4.5

Step-by-step explanation:

We need to find the mean absolute deviation of the following set of data.

10,20,12,4,18,8,14,18

For finding mean absolute deviation, first we need to find the mean of the given data set.

The formula used to calculate mean is: \(Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}\)

Sum of all data points: 10+20+12+4+18+8+14+18 = 104

Number of data points = 8

So, mean is:

\(Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}\\Mean=\frac{104}{8}\\Mean=13\)

Now, we will subtract 13 from the given data points:

10  - 13 = -3

20  - 13 = 7

12  - 13 = -1

4  - 13 = -9

18  -13 = 5

8  - 13 = -5

14  - 13 = 1

18 - 13 = 5

We will take absolute values i.e |-a|=a

So, now the numbers will be:

3,7,1,9,5,5,1,5

We will now find absolute mean deviation by finding mean of newly calculate values

Sum of all data points = 3+7+1+9+5+5+1+5

Number of data points = 8

\(Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}\\Mean=\frac{36}{8}\\Mean=4.5\)

So, the mean absolute deviation of the following set of data is 4.5

The desired minimum revenue is $130.

What is revenue?

Revenue, which is determined by multiplying the average sales price by the quantity of units sold, is the money made from regular business operations. The top line (or gross income) figure is what is used to calculate net income by deducting costs. Sales are another name for revenue in the income statement.

Let us assume,

charge = b

customer= c

revenue= r

We know that,

r= bc

⇒ \(r=16\times 10\)

⇒ \(r=\ 160\)

Also,

\(b+1\) ⇒ \(c-2\)

with a target of \(r \geq 130\)

Therefore,

\(b=10+x\) ⇒ \(c=16-2x\)

\((10+x)(16-2x)\geq 130\\160-20x+16x-2x^2 \geq 130\\-2x^2 -4x+30\geq 0\\x^2+2x-15\leq 0\\(x+1)^2 \leq 4^2\\x+1 \leq 4\)

as negative value is not considered.

\(x\leq 3\)

We get the result that \(\\)3 is the maximum increase amount.

Therefore, revenue will be:

\((10+3)(16-3\times2)=13\times 10\\\)

revenue = \(\\)130

Full Question: Noah manages a buffet at a local restaurant. He charges $10 for the buffet. On average, 16 customers choose the buffet as their meal every hour. After surveying several customers, Noah has determined that for every $1 increase in the cost of the buffet, the average number of customers who select the buffet will decrease by 2 per hour. The restaurant owner wants the buffet to maintain a minimum revenue of $130 per hour. Noah wants to model this situation with an inequality and use the model to help him make the best pricing decisions.
