The model should visually represent that Ms. Duda's class hung 100 lanterns before lunch, which is 20% of the total 500 lanterns.

To draw a model showing what percent of 500 lanterns Ms. Duda's class hangs before lunch, we can use a rectangular bar model.

Draw a rectangular bar to represent the total number of lanterns, which is 500. Label it as "Total Lanterns."

Divide the rectangular bar into two parts. One part should represent the number of lanterns hung before lunch, which is 100. Label this section as "Lanterns Before Lunch."

Calculate the percentage of lanterns hung before lunch by dividing the number of lanterns hung before lunch by the total number of lanterns and multiplying by 100. In this case, (100/500) * 100 = 20%.

Draw an arrow pointing to the "Lanterns Before Lunch" section, and write "20%" next to it to represent the percentage.

The model should visually represent that Ms. Duda's class hung 100 lanterns before lunch, which is 20% of the total 500 lanterns.

Step-by-step explanation:

Answer:

5/8 so he can make 15 meatballs

Step-by-step explanation:

a. C = 5.00 + 0.75t

b. It will cost Elaine $23.00 to park her car for a full 24 hours at the parking lot.

(a) To represent Elaine's total parking cost, C, in dollars for t hours, we can use the following equation:

C = 5.00 + 0.75t

In this equation, the constant term 5.00 represents the flat fee for parking, and the term 0.75t represents the additional cost per hour based on the number of hours (t) the car is parked. By adding the flat fee to the hourly cost, we get the total parking cost for t hours.

(b) To find out how much it will cost Elaine to park her car for a full 24 hours, we can substitute t = 24 into the equation:

C = 5.00 + 0.75 * 24

Calculating this expression, we get:

C = 5.00 + 18.00

C = 23.00

Therefore, it will cost Elaine $23.00 to park her car for a full 24 hours at the parking lot.

Answer:

Option (C) will be the answer.

Step-by-step explanation:

Let the equation of the given line is,

y = mx + b

Where 'm' is the slope of the line and 'b' is the y-intercept

Slope of a line passing through two points (x₁, y₁) and (x₂, y₂) is represented by,

Slope of the line (m) = \(\frac{y_2-y_1}{x_2-x_1}\)

For a line passing through (0, 6) and (4, 0)

Slope 'm' = \(\frac{6-0}{0-4}\)

           m = \(-\frac{3}{2}\)

y-intercept of the line 'b' = 6

Therefore, equation of the line will be,

y = \(-\frac{3}{2}x+6\)

There are 3,125 different places to sit if they don't mind sharing s desk sometimes and there are 120 different places to sit, if they all sit on separate tables.

It is a branch of mathematics that deals with the occurrence of a random event.

Given that there are five different tables in the class and five students

Each table can be occupied by only one student

There are 200 days of studying years.

As a small prank on their teacher students would like to sit in a new way every day, so there are no two days during their studying year such that all students are occupying the same tables.

5×4×3×2×1 = 120

There are 120 different places to sit, if they all sit on separate tables.

5×5×5×5×5 = 3,125

There are 3,125 different places to sit if they don't mind sharing s desk sometimes.

Hence, there are 120 different places to sit, if they all sit on separate tables and there are 3,125 different places to sit if they don't mind sharing s desk sometimes.

The correct value of Jessica's new net salary will be $225.

To calculate Jessica's new net salary after a 5% raise, we need to first determine Sarah's gross salary. We know that Sarah's net salary is $212.50, and 15% of her gross salary is withheld each week.

Let's denote Sarah's gross salary as "G." We can set up the following equation:

G - 15% of G = $212.50

Simplifying the equation, we have:

G - 0.15G = $212.50

0.85G = $212.50

G = $212.50 / 0.85

G ≈ $250

Sarah's gross salary is approximately $250.

Now, to find Jessica's new net salary after a 5% raise, we can calculate 5% of Sarah's gross salary and subtract the withheld amount:

Jessica's net salary = Sarah's gross salary + 5% of Sarah's gross salary - 15% of Sarah's gross salary

Jessica's net salary = $250 + 0.05 * $250 - 0.15 * $250

Jessica's net salary = $250 + $12.50 - $37.50

Jessica's net salary = $225

Therefore, Jessica's new net salary will be $225.

Without explicitly solving for x, we can conclude that the solution to the equation 2^x - 2 = 8^4 is x = 12.

To solve the equation 2^x - 2 = 8^4 without explicitly solving for x, we can simplify the equation using exponent rules and observe the relationship between the numbers.

First, let's simplify the equation:

2^x - 2 = 8^4

We know that 8 can be expressed as 2^3, so we can rewrite the equation as:

2^x - 2 = (2^3)^4

Applying the exponent rule (a^m)^n = a^(mn), we can simplify further:

2^x - 2 = 2^(34)

Simplifying the right side of the equation:

2^x - 2 = 2^12

Now, we can observe that both sides of the equation have the same base, which is 2. In order for the equation to hold true, the exponents must be equal:

x = 12

Therefore, we may deduce that the answer to the equation 2x - 2 = 84 is x = 12 without having to explicitly solve for x.

Answer:

3500

Step-by-step explanation:

\( \frac{7 \times {10}^{5} }{2 \times {10}^{2} } = \frac{7 \times {10}^{3} }{2} = \frac{7 \times 1000}{2} = 7 \times 500 = 3500\)

When dividing 10^5 from 10^2, the degree indicators are subtracted (5 - 2 = 3), so that makes it 10^3

Then, we can write 10^3 as a natural number which is 1000 (the degree indicator in this case shows how many zeros does this number have, 1000 has 3 zeros)

Finally, we divide 1000 from 2, we get 500 and we multiply it by 7

The answer is 3500

2 rides & 4 games

Step-by-step explanation:

2 rides=$8

4 games=$8

8+8=$16

Point (4,2), represents that Victoria played 4 games (x = 4) and went on 2 rides (y = 2).

A graph can be defined as a pictorial representation or a diagram that represents data or values.

The number of games Victoria played, x, and the number of rides Victoria went on, y.

Each game costs $2 and each ride costs $4, so we can set up the following system of equations:

2x + 4y = 16

x + y = 6

To graphically solve this system of equations, we can plot the equations on the same coordinate plane and find the point where they intersect. This point will represent the values of x and y that satisfy both equations.

To plot the equations, we can first graph the equation 2x + 4y = 16.

The slope is 2 and the y-intercept is 4, so we can plot the line by starting at the point (0,4) and moving 2 units up and 1 unit to the right to find the next point on the line.

We can then connect this point to the first point with a straight line to complete the graph of the equation.

Next, we can graph the equation x + y = 6 similarly.

The point will represent the values of x and y that satisfy both equations.

In this case, we can see that the lines intersect at point (4,2), which means that Victoria played 4 games (x = 4) and went on 2 rides (y = 2).
