Using proportions, it is found that the nurse should administer 0.108 mg of digoxin to the client in each dose.

A proportion is a fraction of a total amount.

In this problem, the daily amount is of 0. 03 mg/kg, hence for a person of 7.2 kg, the amount is:

T = 0.03 x 7.2 = 0.216 mg.

This daily amount is given in two equal doses, hence the amount of each dose is given by:

E = 0.216/2 = 0.108 mg.

Answer:

He bought 12 $0.25 costing cards and 8 $0.15 costing cards.

Step-by-step explanation:

Let the number of $0.25 costing cards he bought be s,
Let the number of $0.15 costing cards he bought be t,
According to the question,
He bought a total of 20 game cards,
Thus,
s + t = 20
or, s = 20 - t ------(i)
Now,
Since, he bought s and t no of cards each and it amounted to $4.2, we know,
$0.25s + $0.15t =  $4.2
or, $0.25(20 - t) + $0.15t =  $4.2 [From (i)]
or, $5 - $0.25t + $0.15t =  $4.2
or, $5 - $4.2 = $0.1t
or, $0.8/$0.1 = t
t = 8
From (i),
s = 20 - t = 20 - 8 = 12
Therefore, he bought 12 $0.25 costing cards and 8 $0.15 costing cards.

The common ratio of the geometric progression is r = 2

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the geometric progression be represented as A

Now , the value of A is

A = 2, 4, 8, 16, 32, 64, ...

Now , the common ratio r = second term / first term

On simplifying , we get

r = 4 / 2

r = 2

Hence , the common term of GP is r = 2

The total number of books that are in Francisca's bookcase is 125 books.

Let the total number of books be B.

Given the following data:

Number of paperbacks = 40.

Percentage = 32%.

In this exercise, you're required to determine the total number of books that are in Francisca's bookcase if there she has 40 paperbacks in her bookcase. Thus, we would write a mathematical expression for the word problem.

Translating the word problem into an algebraic expression, we have;

[tex]\frac{32}{100} \times T=40\\\\0.32T=40\\\\T=\frac{40}{0.32}[/tex]

T = 125 books.

19a + 44 - 19a

Group like terms.

[tex]19a - 19a + 44[/tex]

Add similar elements.

[tex]19a - 19a = 0[/tex]

[tex]=44[/tex]

Answer:

44

Step-by-step explanation:

Hahaha, fair enough.

This one may look more difficult than it is. In algebra, there are variables and there are constants.

A constant is a number that is constantly the same, in the example you posted, 44 is the constant.

A variable is like a place holder, it indicates that there is a number that will be substituted in, we just don't know what that number is yet. In your example, the variable is represented by the letter "a."

If youre still a little unsure what a variable is, think of it like this:

Every morning, you like to have one, single cup of coffee, but some days you feel like putting 1 spoon of sugar in, some mornings you want no sugar, and some mornings you really want something sweet and so you have 3 spoons of sugar.

In algebra, your morning cup of coffee is represented 1 + s. 1 is the number of cups of coffee you have and "s" represents how much sugar you put in it. "s" can equal 1, 3, or even 0 spoons of sugar. "s" will represent the number of spoons of sugar consistantly, BUT, keep in mind that while the value of a variable is the same within that one term or equation it can represent a different value in another term or equation.

1 + s on Monday could equal 4 because you really want some sugar at the beginning of your week so you put 3 sugars in. 1 + 3 = 4. But on Thursday, you don't want any sugar, so 1 + 0 = 1. Monday and Thursday are different terms/equations.

SO, because a variable always has the same value within a term/equation, in your example 19a + 44 - 19a, "a" will always have the same value. if a = 1 then your example is 19(1) + 44 - 19(1). If the value of "a" is 1,000,000, then your example looks like 19(1,000,000) + 44 - 19(1,000,000).

We can rewrite your question a little to make it clearer. 19a - 19a + 44, we just swapped the positions of 44 and -19a. So you can see, that no matter what value "a" represents, they will cancel each other out. leaving you with 44 as your answer.

Answer:

4 tiles

Step-by-step explanation:

12 * 10 = 120 for each tile

24 * 20 = 480 for entire floor

480/120 = 4

4 tiles

Answer: Below

Step-by-step explanation:

This is a pretty simple problem, so hopefully you catch on to it quickly.

Since we have two measurements for two sides of a rectangle, we know they are referring to square centimeters for both the floor and the tiles. Since the units match up, we can divide.

24 * 20 = 480 cm squared

12 * 10 = 120 cm square.

480/120 = 4 tiles.

Our answer is 4 tiles.

We must first find how much of the property was unmowed.

If [tex]\dfrac{1}{2}[/tex] of the property was mowed, then that leaves [tex]\dfrac{1}{2}[/tex] of the property unmowed.

Now, we can find the fraction of the property used for the garden.

[tex]\dfrac{1}5}[/tex] of the [tex]\dfrac{1}2[/tex] of the property was used for the garden. To find this as a fraction, multiply [tex]\dfrac{1}5}[/tex] by [tex]\dfrac{1}2[/tex]:

[tex]\dfrac{1}5*\dfrac{1}2=\dfrac{1}{10}[/tex]

Therefore, [tex]\dfrac{1}{10}[/tex] of the property was used for the garden.
