The formula for area is A = bh
B = Length
H = Width

If B is 5 times longer than H...

A = 5x(x)

Now let's solve

20000 = 5(x)(x)
20000 = 5x^2
   /5          /5
  4000 = x^2
    *square*
      20 = x

The height (width) is 20. (x)
The base (length) is 100 (5x -> 5(20) -> 100)

Proof: 20 times 100 = 20000

Please Help, 35 Points.

To answer this question, we have the start-up costs of $ 52,000

A monthly inflation of $ 0 is assumed

Operating costs  are $680

The daily gain  is $960

For the Part A.

The inequality that this situation represents

 960d-680d>52000

So:

d(960-680)>52000

Where d represents the number of days.

For the Part B.

To start earning, you must replace all the initial investment and cover the expenses per day. The time that must pass for this to happen is obtained by clearing "d" from the inequality.


 d>\frac{52000}{960-680}

d> 185.71 days

Then, the sum of the net profits will be greater than the initial investment after 186 days of starting the business.

Can someone help me with this question​
Contact [7]

Answer:

Very Simple!

Step-by-step explanation:

Just use the distance formula!

(I'm in a math class right now, so I have to keep it brief)

Distance Formula, example:

AB=\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2} }

Just input the x and y values from A and B into here, and then that's it!

Hope this helps!

Happy Geometry!
