Q. Saline IV fluid bags cost $64.20 for 24, 1000 ml bags from one supplier. A new supplier sells 500 ml bags for $2 each
Trava [24]

Answer:

The 1000 ml bags, over $3000

Step-by-step explanation:

First, determine how many bags you need from each vendor. Then find the cost per bag with each vendor. Remember, the bags are reported to be only half full when discarded, therefore you need the equivalent of 5,000 1,000 ml bags and 5,000 500ml bags.

lubasha [3.4K]

Answer:

Step-by-step explanation:

cot = cos / sin

tan = sin / cos

=> sin²A × cos²A/sin²A + cos²A × sin²A/cos²

=> cos²A + sin²A

=> 1

I have a really bad grade in Geometry right now and I
Andrews [41]

Answer:  A. (x - 4, y - 2)

               B. (x + 7, y - 11)

<u>Step-by-step explanation:</u>

A) How do you get the x-coordinate of 3 to become a x-coordinate of -1?      by subtracting 4    -->    x - 4

   How do you get the y-coordinate of 5 to become a y-coordinate of 3?      by subtracting 2    -->    y - 2

The transformation is: (x - 4, y - 2)

B)  How do you get the x-coordinate of -4 to become an x-coordinate of 3?     by adding 7    -->    x + 7

    How do you get the y-coordinate of 11 to become a y-coordinate of 0?     by subtracting 11    -->    y - 11

The transformation is: (x + 7, y - 11)

Mr. Ratchett, an elderly American, was found murdered in his train compartment on the Orient Express at 7 AM. When his body was
nasty-shy [4]

Answer: Mr. Ratchett died approximately at 2AM.

Step-by-step explanation: <u>Newton's</u> <u>Law</u> <u>of</u> <u>Cooling</u> shows the cooling rate between a body and the environment, by stating that the rate is proportional to the difference in temperatures between them.

Mathematically, it is represented as:

\frac{dQ}{dt}=\alpha.A.(T_{s}-T)

This differential equation solved, gives the solution:

T(t)=T_{s}+(T_{0}-T_{s})e^{-kt}

where

T_{s} is temperature of the environment

T_{0} is the initial temperature of the body

k is a parameter dependent of heat transfer coefficient, heat capacity and area of the body

t is time required to change the temperature

For the murder on the Orient Express, first determine parameter k.

In 1 hour, Mr. Ratchett's body decrease 1°:

27=22+(28-22)e^{-1k}

5=6e^{-k}

e^{-k}=\frac{5}{6}

ln(e^{-k})=ln(0.834)

k = 0.1823

Using the parameter, find estimate time:

28=22+(37-22)e^{-0.1823t}

6=15e^{-0.1823t}

ln(e^{-0.1823t})=ln(0.4)

0.1823t = 0.9163

t=\frac{0.9163}{0.1823}

t ≈ 5 hours

The body was found at 7AM. So, it took approximately 5 hours to cool down to 28° at that time. Therefore, Mr. Ratchett died at 2AM.
