Final answer:

The multiplication of fractions, such as 1/2 × 2/5, follows the principle of multiplying the numerators and denominators to get the product. This supports the rule that the product of any two fractions is the quotient of the products of their numerators and denominators, which also holds true for fractions less than 1.

Explanation:

The multiplication of fractions, regardless of whether the fractions are less than 1 or not, follows the same basic principles. When multiplying two fractions, you multiply the numerators together and the denominators together. For example, when you multiply 1/2 by 2/5, you multiply the numerators (1 and 2) to get 2, and the denominators (2 and 5) to get 10. The result is 2/10, which simplifies to 1/5. This process supports the general rule of fractional multiplication.

Similarly, when dealing with a fraction such as 1/2 and a fraction less than 1, the product will be less than the original fraction (1/2 in this case). This is because you are multiplying by a number that is less than the whole. For instance, if you multiply 1/2 by 1/3, you get 1/6, which is indeed less than 1/2.

In the context of fractional exponents, the exponent represents the root of the number. So, an exponent of 1/2 would mean the square root.

Question:

A drink dispenser in a fast-food restaurant holds 250 litres of lemonade. How many 0.6-litre drinks can be dispensed before a refill is needed?

Answer:

The number 0.6-litre drinks can be dispensed before a refill is needed is 416

If one bag of stones is sufficient to fill the distance of 4 yards , then to complete 5.5 yards of pond boundary, 2 bags are enough.

Distance is a physical quantity measuring the length over an area covered by an object or place. The change in distance is called displacement. For  a moving object the distance is the product of its speed and time take to cover the distance.

Distance can be measured in meter, kilometer, feet, yard etc. These units can be interchanged in between based on the relationship between them.

It is given that the diameter of the circular fish pond is 5.5 yards. One bag of stones can fills a distance of 4 yards. of the pond. Then two bag of stones is enough  to fill  up the total distance of 5.5 yards.

Answer: About 0.8034 of the items will be classified as good.

Step-by-step explanation:

Let's first understand that because 13% of the items are defective, that means 87% of the items are not defective. And because the inspector incorrectly classifies the items 9% of the time, it's important to understand that that means both the defective and the not defective items may be incorrectly classified. In order to figure out what proportion will be classified as 'good,' let's set up a tree diagram:

--0.13--defective

            |__0.09__ classified as 'good'

            |__0.91__ classified as 'defective'

--0.87--not defective

           |__0.09__ classified as 'defective'

           |__0.91__classified as 'good'

This chart essentially reiterates the information in the prompt, showing that 9% of each type of item will be incorrectly classified. Now we need to find the proportion of items that will be classified as 'good.' To do this, we must multiply the proportion of items classified as 'good' by the proportion of items that are either defective or not defective for both types, like this:

(0.13 * 0.09) + (0.87 * 0.91)

this expression in words means: "13% of the items will be classified as good 9% of the time, and the other 87% of the items will be classified as good 91% of the time"

When we multiply and add these numbers together, we get 0.8034, but you should round to 2 or 3 decimal places like the prompt instructs. Hope this helped! :)

The expression is 436 + x = 515

The number of points they scored in the last game is 79

Step-by-step explanation:

Sally's basketball team played 6 games

We need to write an expression and calculate the number of points they scored in the last game

Assume that the score of the last game is x

∵ Sally's basketball team played 6 games

∵ The score of the first game is 76 points

∵ The score of the next two games is 88 points each

∴ The score of the 2nd game is 88 points and the score

   of the 3rd game is 88 points

∵ The score of each following two games is 92 points

∴ The score of the 4th game is 92 points and the score

   of the 5th game is 92 points

∵ The score of the 6th game is x points

- Add all of them to find the total score of the 6 games

∴ The total score = 76 + 88 + 88 + 92 + 92 + x

- Add the like terms

∴ The total score = 436 + x

∵ The team scored 515 points altogether

- Equate the expression of the total by 515

∴  436 + x = 515

- To find the value of x subtract 436 from both sides

∴ x = 79

∴ The score of the last game is 79 points

The expression is 436 + x = 515

The number of points they scored in the last game is 79

We formulate an expression to represent the overall score of Sally's basketball team and solve for the final game's score. The outcome of the expression found that Sally's team scored 79 points in the last game.

The subject of this question is regarding basketball scoring, which falls under the subject of mathematics, specifically algebraic expressions. The first step in finding out how many points were scored in the last game by Sally's basketball team is to write an expression that represents the total points scored in all games. This could be done as follows:

76 (first game score) + 88*2 (second and third game score) + 92*2 (fourth and fifth game score) + X (sixth game score) = 515 (total score)

To resolve this expression, you first do the multiplications and then the additions. This results in the partial sum of 436 points for the first five games.

Next, subtract this partial sum from the total score (515-436), the outcome is 79.

Therefore, Sally's basketball team must have scored 79 points in the last game.

All you are are doing is inputing the number of games played (x) in for x in the function/equation.

Answer:

So, Domain = {set of all the real numbers except 3, 5}

Interval notation = {x ∈ set of all real numbers/ x ≠3 and x ≠ 5}

Step-by-step explanation:

The given function is f(x) = [tex]\frac{x^2 + 3x - 5}{x^2 - 8x + 15}[/tex]

Here we need to find the domain.

To find the domain, let's find the restricted domain.

If we set the denominator equal to zero and solve for x, we can find the restricted domain.

Here the denominator is [tex]x^2 -8x + 15 = 0[/tex]

Now we can factorize and solve for x.

(x - 3)(x - 5) = 0

(x - 3) or (x - 5) = 0

x -3 = 0  and x - 5 = 0

Solving the above equations, we get

x = 3 and x = 5

The restricted domains are x = 3 and x = 5.

Now we can find the domain.

Except 3 and 5, all the real numbers can be domain of this function.

So, Domain = {set of all the real numbers except 3, 5}

= {x ∈ set of all real numbers/ x ≠3 and x ≠ 5}.

Answer: all real numbers except 3, 5

Step-by-step explanation:

After converting the patient's weight from pounds to kilograms, it is multiplied by the prescribed infusion rate to calculate that approximately 50.88 mL of the IV solution should be infused each hour.

The question involves calculating the volume of IV fluid to infuse per hour based on the weight of the patient and an ordered flow rate. Given that Loc weighs 14 pounds, we need to convert his weight to kilograms to match the units given in the infusion rate (8mL/kg/hr). There are 2.2 pounds in one kilogram.

To find Loc's weight in kilograms, we divide his weight in pounds by 2.2:

Weight in kilograms =Weight in pounds / 2.2 = 14 pounds / 2.2 = 6.36 kilograms (rounded to two decimal places)

Next, we multiply Loc's weight in kilograms by the prescribed infusion rate to determine the flow rate:

Infusion volume per hour =
Weight in kilograms × Infusion rate = 6.36 kg × 8 mL/kg/hr = 50.88 mL/hr (rounded to two decimal places)

Therefore, the nurse should infuse approximately 50.88 mL of the prescribed solution each hour.
