Answer:
The estimated cost of 21 calculators is approximately $4,800
Step-by-step explanation:
we know that
To estimate the total cost of the calculators, multiply the cost of one calculator by the number of calculators, but first round the numbers to the tens place
so
Cost of one calculator-----> $241
Round to the tens place ----> $241=$240
Number of calculators ----> 21
Round to the tens place ----> 21=20
The estimate cost is
(240)(20)=(240)(10)(2)=$4,800
therefore
The estimated cost of 21 calculators is approximately $4,800
Answer:
a. 24.9476 Kg.
b. The safe daily dosage range is between 2494760 units /day and 6236900 units/day
c. Yes
Step-by-step explanation:
a. Lets see the convertion from lb to Kg:
- 1 Lb= 0.453592
- 55 lb = 0.453592*55= 24.9476 kg
b. Minimum daily dosage is 100,000 units /kg
- For this kid: 100,000 * 24.9476= 2,494,760 units/ day
- in 6 dosis; 2494760/6= 415,793.33 units every 4 hours
Maximun daily dosage is 250,000 units /kg
- For this kid: 250,000 * 24.9476= 6,236,900 units/ day
- in 6 dosis; 6,236,900/6= 1,039,483.33 units every 4 hours
c: Yes, because 525.000 units every 4 hours is between the minimun and maximun dosaje for this kid
Answer:
the g's contributing term for the overall uncertainty of P is ![dP_g = [\frac{dg}{g}]](https://tex.z-dn.net/?f=dP_g%20%3D%20%20%5B%5Cfrac%7Bdg%7D%7Bg%7D%5D)
Step-by-step explanation:
From the question we are told that
The pressure is 
The first step in determining the uncertainty of P in by obtaining the terms in the equation contributing to it uncertainty and to do that we take the Ln of both sides of the equation
=> 
Then the next step is to differentiate both sides of the equation
=> 
We asked to obtain the contribution of the term g to the uncertainty of P
This can deduced from the above equation as
![dP_g = [\frac{dg}{g}] P](https://tex.z-dn.net/?f=dP_g%20%3D%20%20%5B%5Cfrac%7Bdg%7D%7Bg%7D%5D%20P)
The value of (26 - 7) and (5 - 24) when they're multiplied will be -399.
<h3>How to multiply the values?</h3>
From the information given, we are told to multiply (26 - 7) and (5 - 24). This goes thus:
= (26 - 7) × (5 - 24)
= 21 × -19
= -399
In this case, value of (26 - 7) and (5 - 24) when they're multiplied will be -399.
