40 % = 16 hours
100 % = 40 hours, the nurse works for 40 hours.
this can be proven by 40% of 40 is 16.

The perimeter would just be the equation that they provided to you multiplied by 3 because a triangle has 3 sides, and it is an equilateral triangle, so every side is the same. You do the distributive property to solve the equation and get your final answer.

Answer:

Answer 1 :-

\implies m_1 = -3

\implies y - intercept = 7

Answer 2 :-

\implies m_1 = -\dfrac{1}{2}

\implies y - intercept = -4

Step-by-step explanation:

The Slope Intercept Form of the line is given to us . The equations given are ,

\implies y + 3x = 7

\implies y + \dfrac{1}{2}x = -4

Now we know the standard equation of slope intercept form , is

\implies y = mx + x

Where ,

  • m is slope
  • c is y intercept .

So , we can write about the equations as ,

\implies y = -3x + 7

\implies y = - \dfrac{1}{2}x  -4

On comparing to the Standard form ,

<u>Answer </u><u>1</u><u> </u><u>:</u><u>-</u><u> </u>

\implies m_1 = -3

\implies y - intercept = 7

<u>Answer </u><u>2</u><u> </u><u>:</u><u>-</u><u> </u>

\implies m_1 = -\dfrac{1}{2}

\implies y - intercept = -4

Hospital sells raffle tickets to raise fund for new medical equipment. Last year, 2000 tickets were sold for $24 each. The fund-
Zanzabum

Answer:

1) Price decrease = $4; 2) new price = $20; 3) maximum revenue = $50 000

Step-by-step explanation:

The hospital sold 2000 tickets for $24 each

Revenue = price per ticket × number of tickets sold

Let x = change in price

New price = 24 - x

New number of tickets sold = 2000 + 125x

1) Calculate change in price to maximize revenue

y = (24 - x)(2000 + 125x)

y = 48 000 + 1000x - 125x²

y = -125x² + 1000x + 48 000

a = -125; b = 1000; c = 48 000

The vertex is at

x = -\dfrac{b}{2a} = -\dfrac{1000}{2(-125)}= \dfrac{1000}{250} = \mathbf{4}

A price decrease of $4 will maximize revenue.

2) New ticket price

Original price = $24

Price change =  <u>  - 4 </u>

New price =       $20

A ticket price of $20 will maximize revenue.

3) Maximum revenue

         Ticket price = $20

No of tickets sold = 2000 + 125(4) = 2000 + 500  = 2500

             Revenue = 2500 × $20 = $ 50 000

The maximum revenue is $50 000.

The graph below slows the relation between the price drop and total revenue.  A price drop of $4 results in a maximum revenue of $50 000.
