Loc weighs 14 pounds. The HCP prescribes an IV infusion of 5% dextrose in 1/4 normal saline to be infused at 8mL/kg/hr. How many mL of the prescribed solution should the nurse infuse each hour?

Answers

Final answer:

To infuse the prescribed solution each hour, the nurse should administer 51 mL.

Explanation:

To calculate the amount of solution that should be infused each hour, we first need to calculate the weight of the patient in kilograms. We can do this by converting the weight from pounds to kilograms using the conversion factor of 0.4536 kg/pound. So, the weight of the patient in kilograms is 14 pounds x 0.4536 kg/pound = 6.3504 kg. Next, we multiply the weight in kilograms by the infusion rate of 8 mL/kg/hr to find the total volume of solution to be infused each hour. Thus, the nurse should infuse 6.3504 kg x 8 mL/kg/hr = 50.8032 mL, which can be rounded to 51 mL each hour.

Solve using elimination

Answers

Answer:

look at the picture shown

Final answer:

The solution to the system of equations 3x+2y=-10 and 2x-5y=3 using the elimination method is x = -44/19 and y = -29/19.

Explanation:

To solve the system of equations 3x+2y=-10 and 2x-5y=3 using the elimination method, we need to multiply the equations by respective constants so that a variable gets eliminated when we add or subtract them. Let's try to eliminate y.

Multiply the first equation by 5 (the coefficient of y in the second equation) and the second equation by 2 (the coefficient of y in the first equation):

5*(3x+2y) = 5*(-10)

2*(2x-5y) = 2*3

15x + 10y = -50

4x - 10y = 6

Add the two equations:

(15x + 10y) + (4x - 10y) = -50 + 6
19x = -44

Divide both sides by 19 to solve for x:

x = -44/19

x = -44/19

Now substitute x back into one of the original equations to solve for y:

3x + 2y = -10

3*(-44/19) + 2y = -10

Multiply 3 by -44/19:

-132/19 + 2y = -10

Now solve for y:

2y = -10 + 132/19

2y = (-190/19) + (132/19)

2y = -58/19

Divide by 2:

y = -58/38

y = -29/19

Therefore, the solution to the system of equations is x = -44/19 and y = -29/19.

On a certain hot​ summer's day, 391 people used the public swimming pool. The daily prices are $1.25 for children and $2.25 for adults. The receipts for admission totaled $752.75. How many children and how many adults swam at the public pool that​ day?

Answers

Final answer:

there were 127 children and 264 adults.

Explanation:

To solve this problem, we use a system of equations. Let's denote the number of children as C and the number of adults as A. We know two facts: the total number of people is 391, and the total amount of money collected is $752.75. Therefore, we have the equations:

C + A = 3911.25C + 2.25A = 752.75

To solve this system, we first multiply the first equation by 1.25 to align the coefficient of C with the second equation:

1.25(C + A) = 1.25(391)1.25C + 1.25A = 488.75

Next, we subtract this result from the second equation to eliminate C, leaving an equation in terms of A only:

2.25A - 1.25A = 752.75 - 488.75

A = (264) / 1 = 264

Substituting the value of A into the first equation, we find the value of C:

C + 264 = 391

C = 127

Therefore, there were 127 children and 264 adults who swam at the public pool that day.

y = 3x +19
y = 5x +33
Solve this system of equation by substitution

Answers

Answer:

( -7, -2)

Step-by-step explanation:

3x + 19 = 5x + 33

x = -7

y= 3x ( - 7) + 19

y= -2

(x, y) = (-7,-2)

The x and y value is -7 and -2.

Given that,

The equations are y = 3x +19 and y = 5x +33.We need to find the value of x and y.

Based on the above information, the calculation is as follows:

3x + 19 = 5x + 33

3x - 5x = 33 - 19

-2x = 14

x = -7

Now put the value of x in any of the above equation

So,

y = 3x + 19

= 3(-7) + 19

= -21 + 19

= -2

Therefore we can conclude that the x and y value is -7 and -2.

Ella and her children went into a bakery and where they sell cookies for $0.50 each and brownies for $2.25 each. Ella has $15 to spend and must buy a minimum of 9 cookies and brownies altogether. If Ella decided to buy 5 cookies, determine the maximum number of brownies that she could buy. If there are no possible solutions, submit an empty answer.

Answers

Answer: 5 brownies

Step-by-step explanation:

cookies = 5 x $0.50 = $2.5

$15 - $2.5 = $12.5

$12.5 divided by $2.25 = $5.555

so at the most ella can buy 5 brownies if she buys 5 cookies

Answer:

If each cookie is .50 and she wants to buy 5 cookies @ .50= $2.50

Than subtract $2,50 from $15.00 (which she has to spend you have $12.50

Then divide 2.25 into $12.5 and you get an answer of 5 brownies with a $1.30 extra to spend

Answer:

The answer is actually (-4, -0.5, 1) in order from least to greatest.

Step-by-step explanation:

A system of equation is a collection of more than one equation

The system of equations to determine the roots of [tex]2x^3 + 4x^2 - x + 5 = -3x^2 + 4x + 9[/tex] are [tex]y = 2x^3 + 4x^2 - x + 5[/tex] and [tex]y= -3x^2 + 4x + 9[/tex]The roots of the polynomial equation are -0.5 and 1

The equation is given as:

[tex]2x^3 + 4x^2 - x + 5 = -3x^2 + 4x + 9[/tex]

Split the equation to a system of equations:

[tex]y = 2x^3 + 4x^2 - x + 5[/tex]

[tex]y= -3x^2 + 4x + 9[/tex]

So, the system of equations to determine the roots of [tex]2x^3 + 4x^2 - x + 5 = -3x^2 + 4x + 9[/tex] are [tex]y = 2x^3 + 4x^2 - x + 5[/tex] and [tex]y= -3x^2 + 4x + 9[/tex]

In Exponential Form:

25 x 51 x 131

CSV Format:

2, 2, 2, 2, 2, 5, 13

The prime factors of 2080 are 2, 2, 2, 2, 5, and 13.

Divide 2080 by the smallest prime number, which is 2:

2080 ÷ 2 = 1040

Continue dividing by 2:

1040 ÷ 2 = 520

Continue dividing by 2:

520 ÷ 2 = 260

Continue dividing by 2:

260 ÷ 2 = 130

Continue dividing by 2:

130 ÷ 2 = 65

Now, 65 is not divisible by 2.

Move to the next prime number, which is 5:

65 ÷ 5 = 13

13 is a prime number.

So, the prime factors of  2080 are 2, 2, 2, 2, 5, and 13. In exponential form, this can be written as 24 * 5 *13.

Area of a rectangle is 100 sq ft. The length is 10 ft longer than twice it’s width. What is the length and the width.

Answers

The length of the rectange is 20ft and width of the 5ft.

Step-by-step explanation:

Let us consider a rectangle and its area is known to be 100 sq ft.

We are given the information that the length of the rectangle is 10ft longer than twice its width.

⇒Length l = 2w+10.

Where w is the width of the rectangle.

The formula for area of the rectangle A = length × width.

A= (2w+10)×w.

100 = [tex]2w^2+10w[/tex].

0=[tex]2w^2+10w-100[/tex].

Thus it forms an quadratic equation we have to solve for the solution.

0=(2w-10)(w+10).

2w-10=0.    w+10=0.

2w=10.        w=-10. (negative value cannot be choosed.)

w=[tex](\frac{10}{2} )[/tex].        

w=5ft.

Thus width is is 5 ft.

Length = 2(5)+10.

=10+10.

=20ft.

Thus the length is 20ft.

Step-by-step explanation:

A data set that has a mean absolute deviation of 0 means the average difference between  the elements in a data set and mean of the same data set is very less.

What is Mean absolute Deviation?

The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.

As we know the mean absolute deviation is the average distance between each data point and the mean.

If more than 50% of your data have identical values, your MAD will equal zero.

Also, the mean absolute deviation of a dataset is the average distance between each data point and the mean.

If the mean absolute deviation (MAD) is close to 0,it means the average difference between the elements in a data set and mean of the same data set is very less.

Thus,  the average difference between  the elements in a data set and mean of the same data set is very less.
