9. A doctor charges each patient $75 per consultation. If she works for 6 hours during one day and sees an average of six patients per hour, what was her profit that day? (Her costs per day are $200 for insurance, $200 for leasing the building and $50 for paying the reception desk).​

Answers

Answer:

She makes $2,250/day

Step-by-step explanation:

$75 x 6 = $450 (amount of patients seen)

$450 x 6 = $2,700 (amount of hours she works)

$2,700 - $450 = $2,250 (the cost of the building, reception desk, & insurance)

S O L U T I O N :

We are given that the doctor charges $75 for each patient

In each she sees an average of 6 patients so,

Charge each hr = $75(6) = $450

For each hr she receives $450

So, for 6 hrs she receives = $450(6) = $2700

She pays for all the stuff = $200 + $200 + $50 = $450

Profit = Selling Price - Cost Price

Profit = $2700 - $450

Profit = $2250

Hence, she earns a profit of $2250 that day

Write the equation of the line that passes through the points
(3,-2) and (6, 1).
y=x-5
y = 5x + 1
y = -x + 5

Answers

Answer:

It is y = x - 5

Step-by-step explanation:

General equation of a line:

[tex]{ \bf{y = mx + c}}[/tex]

m is the gradient, and c is y-intercept.

For gradient:

[tex]slope = \frac{y_{2} - y_{1} }{x _{2} - x_{1}} [/tex]

substitute:

[tex]slope = \frac{1 - ( - 2)}{6 - 3} \\ \\ = \frac{3}{3} \\ slope \: = 1[/tex]

m = 1

for y-intercept:

consider point (6, 1):

[tex]y = mx + c \\ 1 = (6 \times 1) + c \\ 1 = 6 + c \\ c = 1 - 6 = - 5[/tex]

therefore:

[tex]{ \sf{equation \: is \: \{y = x - 5 \}}}[/tex]

A square sandbox has an area of 42ft to the power of 2. What is the approximate perimeter of the sandbox to the nearest hundredth?

Answers

Assuming I’m reading your question correctly, that the area is 42 square feet…

The length of each side is then sqrt(42) feet or about 6.480741 feet.

Since a square has four sides, you’d have 4*6.480741 for the perimeter, or about 25.922964 feet.

Rounding this to the hundredths place, you’d have 25.92 feet.

Solve the following equation for X to find the total number of people who downloaded songs for music site for a certain month.

X= 0.6x + 384
How many people downloaded songs from the site that month?

Answers

Answer:

960

Step-by-step explanation:

x=0.6x+384

0.4x=384

960

Answer:

960

Step-by-step explanation:

x = 0.6x + 384

Subtract 0.6x in both sides:

0.4x = 384

Divide both sides by 0.4:

x = 384/0.4

x = 960

Consider the points (5,0) and (0,3). Plot the points and find the distance between them. Give your answer both in exact form and as a decimal approximation.​

Answers

Answer:

(5;3)

Step-by-step explanation:

Give your answer both.

The distance between the points (5, 0) and (0, 3) is approximately 5.83095 units.

To find the distance between two points, we can use the distance formula:

Distance = √[tex]((x_2 - x_1)^2 + (y_2 - y_1)^2)[/tex]

Given the points (5, 0) and (0, 3), we have:

[tex]x_1 = 5, y_1 = 0\\\\x_2 = 0, y_2 = 3[/tex]

Substituting these values into the formula:

Distance = √[tex]((0 - 5)^2 + (3 - 0)^2)[/tex]

Distance = √[tex]((-5)^2 + (3)^2)[/tex]

Distance = √(25 + 9)

Distance = √34

The exact distance between the points is √34, which is approximately 5.83095 when rounded to five decimal places.

So, the distance between the points is approximately 5.83095 units.

b. The sum of three numbers is 51. The second number is three more than the first number, and the third number is
Two times the value of the first number. What are the three numbers?

Answers

Answer:

12, 15, 24

Step-by-step explanation:

Let 1st # = x

Let 2nd # = x+3

Let 3rd # = 2x

Your equation is: x + (x+3) + 2x = 51

Add up all the x: x + x +3 +2x =51

Subtract 3 from both sides: 4x + 3 - 3 = 51 - 3

Divide 4 from both sides: 4x / 4 = 48 / 4

Your 1st number is x = 12

For the 2nd # it is 3 more than x so 12 + 3 = 15

For the 3rd # it is 2 times x so 2(12) = 24

Check your answers by adding up the numbers you solved: 12 + 15 +24 = 51

Does it equal to 51 as stated in the question? Yes, answers check out.

Answers

Hello!

To start off, remember that supplementary angles are angles that add up to 180 degrees. Therefore, we know the sum of these two angles will be 180 degrees.

So, we must add the two angles together, then set it equal to 180 and solve for x!

(X)+(17x+72)=180

Now, solve for x!

18x+72=180

Subtract 72 from each side

18x= 108

Divide by 18 to get x

X=6

Therefore, the measure of the first angle (x) is 6 degrees.

Now, substitute that number into the “x” in the second angle.

(17*6)+72= 174 degrees

Therefore:

The first angle is 6 degrees

The second angle is 174 degrees

I hope this helped! Comment if you have any questions!

can someone help pls​

Answers

Answer:

[tex]x=5[/tex]

Step-by-step explanation:

1. Approach

The most logical steps to solve the given equation are to distribute and simplify the left side of the equation. Then use inverse operations to bring all of the terms to the left side of the equation. After doing so, one can factor the equation again, then use the zero-product property to solve it.

2. Simplify

Distribute the terms on the left side, multiply everything in the first parenthesis by everything in the second,

[tex](x+1)(x-11)=-36[/tex]

[tex](x)(x)+(1)(x)+(-11)(x)+(1)(-11)=-36[/tex]

Simplify this expression by performing the multiplication and then combining like terms,

[tex](x)(x)+(1)(x)+(-11)(x)+(1)(-11)=-36[/tex]

[tex]x^2+x-11x-11=-36[/tex]

[tex]x^2-10x-11=-36[/tex]

Inverse operations,

[tex]x^2-10x-11=-36[/tex]

[tex]x^2-10x+25=0[/tex]

3. Factor and solve,

Now that has the simplified version of the equation, one should factor it. Rewrite the quadratic expression as a product of two linear expressions,

[tex]x^2-10x+25=0[/tex]

[tex](x-5)^2=0[/tex]

Use the zero product property to solve this expression. The zero product property states that any number times zero equals zero. Since ([tex](x-5)^2[/tex]) is just ([tex]x-5[/tex]) multiplied by itself, thus, when solving, one can ignore the square part of the equation:

[tex](x-5)^2=0[/tex]

[tex]x-5=0[/tex]

Inverse operations,

[tex]x-5=0[/tex]

[tex]x=5[/tex]

Step-by-step explanation:

We want to solve the inequality:

[tex]\displaystyle 5.1(3 + 2.2x) > -14.25 - 6(1.7x+4)[/tex]

Distribute:

[tex](15.3+11.22x) > -14.25 + (-10.2x-24)[/tex]

Combine like terms:

[tex]15.3 + 11.22x > -10.2x-38.25[/tex]

We can add 10.2x to both sides:

[tex]15.3 + 21.42x > -38.25[/tex]

Subtract 15.3 from both sides:

[tex]21.42x > -53.55[/tex]

And divide both sides by 21.42. Hence:

[tex]\displaystyle x > -2.5[/tex]

This means all values greater than -2.5. Hence, in interval notation:

[tex](-2.5, \infty)[/tex]

In conclusion, our answer is C.

Three friends were at a festival together and they won 20 small prizes. They decided to split the prizes as evenly as possible. How many prizes will they each get?

Answer:

Each of the friends will get 6 with 2 small prizes remaing

Step-by-step explanation:

20 ÷ 6 = 18 remainder of 2

Ignore the 2 because you cannot split 2 evenly from 3 people.

So each friend gets 6, while there is a 2 remainder

To check our work just do 6 × 3 = 18 and 20 - 18 = 2

So, in conclusion, each friend get 6 while there are 2 small prizes left
