If an intravenous fluid is adjusted to deliver 15 mg of medication to a patient per hour, how many milligrams of medication are

adelina 88 [10]

Answer: 0.125 mg per half minute

Step-by-step explanation:

15mg per hour can be written as 15mg/h

To find out how many mg of medication are delivered per half minute you can convert from hour to minutes

There are 60 minutes in 1 hour, so you can use the conversion factor (1h/60 min) and multiply the expression by it

15 mg/h (1h/60min) = 0.25 mg/min

But the question is per half minute so you have to multiply and divide the previous expression by 0.5 (To obtain 0.5 min in the denominator, which is half minute)

Then,

(0.25 mg/min ) (0.5/0.5) = 0.125 mg/ 0.5 min (0.125 mg per half minute)

IgorLugansk [536]

Answer:

True

Step-by-step explanation:

Assemble line is a production process in which parts are joined to the products produced as a partially finished product.

Here the process flow is discreet that is assembled one at a time.

Continous process flow is a type of manufacturing products without disruption of the flow process.

As the name implies,it is continous.

Three times the square of a number if five less than sixteen times the number. What is the number?

expeople1 [14]

X - the number

$3x^2=16x-5 \\
3x^2-16x+5=0 \\
3x^2-15x-x+5=0 \\
3x(x-5)-1(x-5)=0 \\
(3x-1)(x-5)=0 \\
3x-1=0 \ \lor \ x-5=0 \\
3x=1 \ \lor \ x=5 \\
x=\frac{1}{3} \ \lor \ x=5$

The number is 1/3 or 5.

How many 8's are in the answer and sum 5890/45?

Novay_Z [31]

Answer:

1. There are infinite 8's

2. The estimate is 130.89

3. The difference is 0.01

Explanation:

There are countless, or infinite, 8's in the answer because the result is a periodic decimal:

$\dfrac{5890}{45}=130.8888 . . .$

The notation used for the periodic decimal numbers is an arc over the number that is repeated. In this case, it would be an arc over the first 8.

I will use a bar just to show how it is, but instead of a bar it should be an arc:

$\dfrac{5890}{45}=130.\overline 8$

The estimation or approximation to two decimal places requires to drop the 8's since the third one and increase the second 8 to 9 (because the first decimal dropped is greater than or equal to 5).

Thus the estimated value would be 13.89.

The difference is:

130.89 - 130.888. . . = 0.0111. . .
Rounded to 2 decimal places: 0.01
