What is the area of this quadrilateral

Answers

Answer:

C

Step-by-step explanation:

First, let's work out the two triangles:

Area of triangle: bxh/2

2 x 8/2 = 8

Because there is two triangles multiply 8 by 2 = 16

To work out the area of the central rectangle:

Area of rectangle: l x w

3 x 8 = 24

Add 16+24 = 40 square feet

Solve the following question

Answers

Answer:

x=-1

Step-by-step explanation:

First we can square both sides to remove the square roots:

[tex](\sqrt{x+7})^{2} +(\sqrt{x+2})^{2} = (\sqrt{6x+13})^{2}[/tex]

Simplify:

[tex]x+7+x+2=6x+13[/tex]

Now we simplify further:

[tex]2x+9=6x+13[/tex]

Now we subtract 13 from both sides:

[tex]2x+9-13=6x+13-13[/tex]

Simplify:

[tex]2x-4=6x[/tex]

Subtract 2x from both sides:

[tex]2x-4-2x=6x-2x[/tex]

Simplify:

[tex]-4=4x[/tex]

Divide both sides by 4:

Complete the steps to solve the equation -18x - 17 = 107 write the original equation apply the addition property of equality

Answers

Answer:

[tex]-\frac{62}{9}[/tex]

Step-by-step explanation:

The properties of equality state that you are allowed to perform operations on an equation as long as the operations are done equally on both sides.

Solving the Equation

First, rewrite the equation

[tex]-18x - 17 = 107[/tex]

Next, apply the addition property of equality and add 17 to both sides

[tex]-18x=124[/tex]

Finally, apply the division property of equality and divide both sides by -18

[tex]x=\frac{124}{-18}[/tex]

Then, simplify for the final answer (divide numerator and denominator by 2)

[tex]x=-\frac{62}{9}[/tex]

a company’s profit of 18000 is shared by 2 directors and 24 employees 1-3 of the profit is shared equally by 2 directors of the company

Answers

Using proportions, it is found that:

Each director gets 6000.Each employee gets 500.

What is a proportion?

A proportion is a fraction of a total amount.

In this problem, the directors share one-third of the profit, hence:

18000/3 = 6000

6000/2 = 3000.

That is, each director gets 6000.

The remaining 18000 - 6000 = 12000 will be shared equally by the 24 employees, hence:

12000/24 = 500

Each employee gets 500.

Answers

The worth of the car after it is paid off 5 years later given the rate of exponential depreciation is $32,842.34.

What is the worth of the car?

When the car declines in value, it means that the car is depreciating. The formula that can be used to determine the value of the car with the depreciationn rate is:

FV = P (1 - r)^n

[tex]y=-3(8)^{x}[/tex]

Step-by-step explanation:

to make a sketch of this graph. We're gonna make a table of values. I think that's probably our best route. So we'll do a couple negative values, but I'm gonna actually start at 08 to 0. Power zero. And I'm sorry. 80 parts one and one times negative. Three is negative. Three eight to the first. Power is eight and eight times negative. Three is negative. 24 8 X squared is 64 64 times negative. Three is on negative. 192. Okay, I think that's plenty. E to the negative. First power is 18 and 1/8 times negative. Three is negative. 3/8 and eight to the negative. To power is 1 64th times negative. Three is negative. 3 60 force. Okay, I think we can see where that's going. Is getting really close to zero. So as faras my graph here, I'm gonna focus on the fourth quadrant, I think. All right. So we got our X and y axis here. We're starting at 01 and to and we'll also do negative one. And negative two aren't horizontally, vertically. I do. I want to scale this whole the way to 1 92 I guess I will. Um, so whatever it is scaled by, maybe twenties. Yeah, let's do that. 20 40 60 8120 40 60 8200. So there's negative. 200? Um, negative. 1 80 Negative 1 60? Nope. That's not right. Because I scaled by twenties didn't. So this is actually negative. 1 60 This one's negative. 1 20 This one's negative. 80. And this is negative. 40. There we go. All right now a plot. These points to negative 1 92 is practically to 200 one. Negative. 24 is all the way over here. Zero negative three is practically on the X axis The way I have this, and same with those fractional values. They're practically on the X axis. So let's start almost parallel to the X axis because it's never actually touch step than its we don't ever. Slowly and then it starts going down rapidly, decreasing in value to the point where it's almost vertical, but it never will get vertical, so there's a decent sketch of y equals negative three times eight to the power of acts

Green pencils are priced at $1.28 for 4. Blue pencils are priced at $5.52 for 24. Which of the following statements are true?

The unit rate for blue pencils is $0.28
The unit rate for green pencils is $0.32
The green pencils are priced less per pencil
The blue pencils are priced less per pencil.

Answers

Correct Statements:

1) The unit rate for green pencils is $0.32

2) The blue pencils are priced less per pencil.

Step-by-step explanation:

UNIT RATE:

Green pencils:

Given that,

4 green pencils = $1.28

Divide 4 to both sides

1 green pencil = $1.28 / 4

1 green pencil = $0.32

Blue pencils:

Given that,

24 blue pencils = $5.52

Divide 24 to both sides

1 blue pencil = $5.52 / 24

1 blue pencil = $0.23

Blue pencil is priced less per pencil when compared to green pencil.

You buy 45 shares of evu confectioners at $63.12 apiece. unfortunately, the company falls on hard times and you end up selling the stock for $41.20 per share. how much money did you lose? a. $1,854.00 b. $986.40 c. $1,183.68 d. $2,840.40

Answers

Answer:

b is your answer to this question

The money lost due to a hard time for the company is $986.4.

Number of shares =45

Price per share =$63.12

So, the total cost of buying 45 shares = 45*63.12 = $2840.4

Total selling price when the company falls on hard times and you end up selling the stock for $41.20 per share = 41.20*45 = $1854

What is a loss?

Mathematically, the loss is the difference between the cost price and the selling price.

Difference between the selling price and the cost price = 2840.4 - 1854

So, the difference between the selling price and the cost price = $986.4

Therefore, The money lost due to a hard time for the company is $986.4.

Yes it does include the test point (0, 0)

Find y-intercept: y > -3(0) -5 y > -5

Find x-intercept:y > -3x -5

switch sides

-3x - 5 < 0-3x < 5

Multiply both sides by -1 reverses the inequality

Ann and Makiko like to swim laps at the community center pool.

They are swimming together today (day 1), but they are on different swim schedules. Ann swims every three days and Makiko swims every five days.

Question: How many times will they both swim at the pool on the same day
during the next ten weeks (including the first day)?

please explain process and show thinking in steps.

Answers

Answer:   5

=========================================================

Explanation:

The LCM of 3 and 5 is 3*5 = 15.

Every 15 days, the two people will swim together on the same day.

Day 1 = first day swimming togetherDay 1+15 = Day 16 = second day swimming togetherDay 16+15 = Day 31 = third day swimming together

And so on.

Keep this process going of adding on 15 to find this sequence

1, 16, 31, 46, 61, 76, ...

We stop the sequence once we either reach 70 or go over it because there are 7*10 = 70 days in ten weeks. This assumes we use a 7 day week rather than a 5 day week.

As shown in bold, there are 5 items smaller than 70. So the two people swam together a total of 5 times

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

Alternatively, you can solve 15n+1 = 70 for n to get n = 4.6 which rounds down to n = 4 to represent the set {0,1,2,3,4} which has 5 items in it to represent the five times total they swim together.

n = 0 corresponds to day 15n+1 = 15(0)+1 = 1n = 1 corresponds to day 15n+1 = 15(1)+1 = 16

and so on until reaching n = 4 corresponding to day 15(4)+1 = 61.
