Tim bought 2 pounds of apples for $0.50 per pound. He also bought 1.5 pounds of cookies for $2.10 per pound. Tim gave the cashier $10 for the apples and cookies. How much change did he receive?

Answer

She paid 17.99 in sales tax

Step-by-step explanation:

The 16 oz bottle of fruit punch, costing $0.15 per ounce, is a more economical choice compared to the 24 oz bottle, which costs $0.16 per ounce.

To determine which size of fruit punch costs less per ounce, we need to calculate the cost per ounce for each bottle size. For the 16 oz bottle costing $2.40, we divide $2.40 by 16 oz, giving us $0.15 per ounce. For the 24 oz bottle costing $3.84, we divide $3.84 by 24 oz, resulting in $0.16 per ounce. Thus, we can see that the 16 oz bottle has a lower cost per ounce compared to the 24 oz bottle.

To further clarify, here are the calculations:

Comparing the two, the 16 oz bottle's cost per ounce is $0.01 less than the 24 oz bottle, making it the more economical choice.

The value of the missing number in the given ratio 63:27= 49:? is 21.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

As per the given ratio,

63:27= 49:?

Let's assume the missing number is x.

63/27 = 49/x

Multiply both side by x.

x(63/27) = 49

Multiply both side by 27/63

x = 49(27/63)

x = 21

Hence "The value of the missing number in the given ratio 63:27= 49:? is 21".

The practical domain of the function f(x)=−85x+3145, which represents the number of unprinted pages x minutes after the printing begins, is from 0 to 37. Here, the value of 'x' are whole numbers since it represents time in minutes, and in this context, fractions or decimal amounts of minutes do not apply.

In Mathematics, particularly in the topic of functions, the practical domain refers to the set of all possible values of x, for which the function is defined. In this particular problem, the function f(x)=−85x+3145f(x)=−85x+3145 represents the number of unprinted pages x minutes after the printing begins.

Given that the printer prints 85 pages per minute and there are 3145 pages to print in total, it will take the employee 3145/85 = 37 minutes to print all the pages. Therefore, the practical domain of this function f is all whole numbers from 0 to 37 inclusive.

Keep in mind, these are whole minutes. It may not make practical sense to consider fractions or decimals of minutes in this problem context as the printer operates at set whole minute intervals. So, the practical domain does not include real numbers between 0 and 37, only whole numbers.

So the practical domain of function f is all whole numbers from 0 to 37.

The Sun produces energy through nuclear fusion in its core. Visiting the Sun is not possible due to high temperatures and intense radiation. Scientists use special instruments to observe the Sun safely.

The Sun produces energy through the process of nuclear fusion. In the Sun's core, hydrogen atoms combine to form helium atoms, releasing a tremendous amount of energy in the process. This energy is then radiated outwards in the form of light and heat. However, visiting the Sun is not feasible due to its extremely high temperatures and intense radiation. If one were to approach the Sun, they would burn up before reaching it.

As an analogy, imagine you are attending a crowded rally and need to work your way through the dense crowd to reach the edge. Photons in the Sun's core behave similarly, constantly bumping into atoms and changing direction as they make their way outwards. They only become visible when they reach the Sun's atmosphere, where the density of atoms is low enough to allow their outward progress.

To observe the Sun and learn about its characteristics, scientists use instruments like telescopes equipped with special filters that block harmful radiation and enable safe observations. These observations help us understand the Sun's behavior and its impact on Earth.

Final answer:

The Sun produces energy via nuclear fusion in its core, where hydrogen atoms fuse to create helium, emitting light and heat. The photosphere, just over 400 kilometers thick, is the layer from which visible light is emitted. Physically visiting the Sun would be impossible due to its extreme conditions, yet exploring its energy production and photonic behavior is intriguing.

Explanation:

To address the question of how the Sun produces so much energy for such an extended period, one must understand that the Sun has been generating energy for about 4.5 billion years through nuclear fusion processes. In the Sun's core, hydrogen atoms fuse to form helium under extreme temperatures and pressures, releasing vast amounts of energy in the form of light and heat. This process is similar to having an incredibly long-lasting 'nuclear battery' that provides the energy that we see as sunlight.

An interesting analogy to understand the journey of a photon from the Sun's core to the outside is by imagining being in a crowded rally and trying to get from the center to the edges; you would constantly bump into people, change direction, and only gradually make your way out. Photons behave the same way inside the Sun, constantly interacting with atoms and only becoming visible when they reach the Sun's atmosphere where atom density is low. This atmosphere, or photosphere, is about 400 kilometers thick, relatively thin compared to the Sun's diameter, and it's from this layer that the bulk of the Sun's visible light we see is emitted.

Waiter A and waitress B will charge the same amount of money in 5 hours and which is $48.75.

The equation is defined as mathematical assertions that have a minimum of two terms containing variables or numbers that are equal.

As per the question, we can write the equations as:

For Waiter A, this is given by the equation 25 + 4.75h,

For Waitress B, the equation is 30 + 3.75h.

where h is the number of hours.

We can set up the equation 25 + 4.75h = 30 + 3.75h by equating the total amount each waiter will charge. Solving for h, we get:

25 + 4.75h = 30 +

4.75h - 3.75h = 30 - 25

h = 5

This means that at 1.05 hours, both waiters will charge the same amount of money.

The total amount they will charge is:

⇒ 25 + 4.75(5)

⇒ 30 + 3.75(1.05)

⇒ $48.75.

Thus, they will charge the same amount of money in 5 hours and which is $48.75.

The decimal 0.79 as a fraction in simplest form is 79/100, which cannot be simplified further.

To convert the decimal 0.79 into a fraction in simplest form, we have to write it as a fraction with a denominator that reflects the decimal's place value. Since 0.79 has two decimal places, it equates to 79/100. This fraction cannot be simplified further since 79 and 100 have no common divisors other than 1, thus 79/100 is the fraction in simplest form.

Equivalent fractions represent the same portion of a whole, despite having different numerators and denominators. By increasing the number of equally divided parts of a whole and accordingly adjusting the number of shaded parts, you create equivalent fractions such as 1/2 and 3/6, which look different but represent the same amount.

The question is addressing a concept in Mathematics, specifically the idea of equivalent fractions and how changing the number of parts in a whole affects those fractions. When you look at the model showing 1/2 = 3/6, you see that the whole is divided into different numbers of parts. The fraction 1/2 means that one out of two equal parts of the whole is shaded, whereas 3/6 indicates that three out of six equal parts of the whole are shaded.

To understand this, imagine dividing a shape into two equal parts. Shading one of these gives you 1/2. If you further divide each half into three parts, making six equal parts in total, and shade three, you still have the same amount shaded (which is half) but in terms of six parts now, hence 3/6. This shows that by increasing the number of parts into which the whole is divided, while maintaining the proportion of the shaded area, you increase both the numerator and denominator of the fraction proportionally, thus creating what is known as an equivalent fraction.

Micah has 33 red marbles and 22 blue marbles.

To find out how many red and blue marbles Micah has, we first need to divide the total number of marbles by the sum of the parts of the ratio (which is 3 + 2 = 5), and then multiply each part of the ratio by this result.

First, let's find the value of each part of the ratio:

- Each part represents a fraction of the total: [tex]\( \frac{55}{5} = 11 \)[/tex] marbles per part.

- Since the ratio of red to blue marbles is 3:2, we have:

 - Red marbles: [tex]\( 3 \times 11 = 33 \)[/tex] marbles

 - Blue marbles: [tex]\( 2 \times 11 = 22 \)[/tex] marbles

So, Micah has 33 red marbles and 22 blue marbles.
