Answer:

100 adult tickets

150 students tickets

Step-by-step explanation:

First, construct an equation that relates the tickets.  

For the first equation, 5x represents $5 per ticket for students and 8y represents $8 per ticket for adult, showing the money earned.  

For the second equation, x represents student tickets and y represents adult tickets, showing the tickets sold.

[tex]5x+8y=1550\\x+y=250\\[/tex]

Then, you have to cancel out similar factors.  I will multiply the second equation by -5 because that is the easiest option for this specific case.

[tex]-5(x+y=250)\\-5x-5y=-1250\\5x+8y=1550\\3y=300\\y=100[/tex]

We have solved for y, which is how many adult tickets were sold.  To solve for student tickets, we will solve the second equation.

[tex]x+y=250\\x+100=250\\x=150[/tex]

As a result we have 100 adult tickets and 150 student tickets.

Answer:

$69.00

Step-by-step explanation:

Hi there,

In order to solve this problem, I used this formula:

Dollar Markdown = (markdown %)(original price)

You will end up with Markdown = (0.4) (115).

(Be sure to convert the percentage to a decimal value. (ex. 40% = 0.4))

After multiplying, we find that 46 dollars is 40% of the original price.

For the final step, simply subtract the original price by the amount marked down to get $69.00.

Hope this was useful. Cheers.

The volume of the rectangular pyramid with the given values of height and base area is 138.5 cubic inches.

A right triangular pyramid is simply a triangular pyramid which has an equilateral base, and whose top is directly above the base's centroid.

The volume of right triangular pyramid is expressed as;

V = 1/3 × b² × h

where b is the length of the base and h is the perpendicular height.

Given the data in the question;

First we find the dimension of the base length.

Since area square is A = b².

Hence;

41.57in² = b²

b = √41.57in²

b = 6.447in

Now, we substitute our values into the expression above.

V = 1/3 × b² × h

V = 1/3 × (6.447in)² × 10in

V = 1/3 × 41.563809in² × 10in

V = 138.5in³

Therefore, the volume of the rectangular pyramid with the given values of height and base area is 138.5 cubic inches.

Answer:

x=1/3

Step-by-step explanation:

You have to isolate the variable, so you must first separate the constants from the variable. Add 3 on both sides to cancel out the minus three and to move it to the other side. Now you have 27x=9. It's pretty simple from there just use your calculator and divide 27x/27 and also 9/27. That leaves you with 1/3

To solve for x in the equation 27x+3=6, we subtract 3 from both sides, divide both sides by 27, and get the solution x = 1/9.

To solve for x in the equation 27x+3=6, we'll start by isolating the variable x. First, subtract 3 from both sides of the equation to get 27x = 3. Then, divide both sides by 27 to find the value of x.

Therefore, the solution to the equation is x = 1/9.

The total height of the stairs can be found by adding the distance from the ground to the end of the slide (7 feet) and the extra height of the stairs (2 feet). This adds up to a total height of 9 feet for the stairs.

The subject of the question is Mathematics, and it's suitable for a Middle School level. The problem can be solved using basic addition, and the concept of distance and height.

First, identify the length of the slide, which is 13 feet. Next, you're told that the end of the slide is 7 feet away from the stairs. This distance represents the height from the ground to the end of the slide. Lastly, you're told that the stairs extend 2 feet higher than the end of the slide.

Add these two distances together. So, the total height of the stairs is 7 feet (height to end of slide) plus 2 feet (additional height of stairs) equaling 9 feet.

So, the stairs are 9 feet tall.

Using the relation between arc length and the radius, the arc length covered by the bat tip for a swing of 255 degrees with a 48-inch radius bat is (85/6)π inches or (85/72)π feet.

The subject of the question is based in mathematics, specifically geometry. To solve the question, first, we have to know that the circumference (C) of a given circle is calculated as

2πr

, where 'r' is the radius. Since 255° is a portion of the total circumference (which is considered as 360°), we calculate the fraction of the total circumference covered by 255°, which is 255/360. The arc covered by Janis's bat swing is, therefore,

(255/360)*2πr

. Substituting 'r' with 48 inches, the arc length (As) comes to

(85/6)π inches

. To convert this to feet, divide the result by 12 (since there are 12 inches in one foot), which gives

(85/72)π feet

Step-by-step explanation:

positive 180 degresse rotation

Positive angles result from counterclockwise rotation, and negative angles result from clockwise rotation.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle.

The difference between the positive and negative angles :-

Angles are sometimes classified based on whether their values are more than or less than 0° into positive and negative angles. The measure of a positive or a negative angle depends on the amount of rotation between the two sides forming the angle. The rotation is measured from the initial side to the terminal side of the angle.

What is a Positive Angle :-

An angle formed by an anti-clock wise or counterclockwise rotation from its initial side is called a positive angle.

12°, 33°, 90°, 180°, 360° are all example of positive angles.

What is a Negative Angle :-

An angle formed by a clockwise rotation from its initial side is called a negative angle.

-9°, -45°, -110°, -280°, -310° are all example of negative angles.

Final answer:

To determine the total lodging cost for Juanita's 4-night stay, multiply the nightly rate by the number of nights to get the pre-tax cost, calculate the total tax rate and apply it to the pre-tax cost to find the tax amount, and then add this tax to the pre-tax cost for the total cost. The total lodging cost, including taxes, will be $344.44.

Explanation:

Juanita is trying to calculate the total cost of a 4-night stay at a hotel with a nightly rate and additional taxes. To find Juanita's total lodging cost, a multi-step calculation is required. First, calculate the cost before tax by multiplying the nightly rate by the number of nights. Then, calculate the total tax by adding the state, city, and municipal tax rates and applying this sum to the pre-tax cost to get the total tax amount. Finally, add the tax amount to the pre-tax cost to find the total cost of the stay.

The nightly rate is $79 and she is staying for 4 nights, so the initial cost (before tax) is calculated as follows:

79 x 4 = $316

To calculate the total tax, convert the percentages to decimals and sum them up as follows:

State tax (6%) = 0.06
City tax (2%) = 0.02
Municipal tax (1%) = 0.01
Total tax rate = 0.06 + 0.02 + 0.01 = 0.09

Multiply the total tax rate by the pre-tax cost to find the total tax amount:

0.09 x 316 = $28.44

Finally, add the tax amount to the pre-tax cost to get the total lodging cost:

316 + 28.44 = $344.44

The total cost for Juanita's 4-night stay at the hotel, including all taxes, is $344.44.

Answer:

Katie saved $20.

Step-by-step explanation:

I assume that "served" is a typo for "saved". Also, I assume that Tata and Ted are the same person.

Let the amount Katie saved = k

Then, ted saved $6 less than 4 times k, or 4k - 6.

The total saved by both is k + 4k - 6.

The total saved by both is $94.

k + 4k - 6 = 94

5k - 6 = 94

5k = 100

k = 20

Answer: Katie saved $20.

Final answer:

To determine the amount Katie has saved, two equations were set up based on the given information. The equations were solved simultaneously to find that Katie has saved $20.

Explanation:

Let's denote the amount Katie has saved as K and the amount Tata has saved as T. According to the problem, Tata saved six dollars less than four times as much as Katie, which we can write as T = 4K - 6. Additionally, we know that together they have saved a total of $94, so we can express this as K + T = 94. Substituting the expression for T from the first equation into the second equation, we get K + (4K - 6) = 94. Simplifying this, we get 5K - 6 = 94. By adding 6 to both sides, we obtain 5K = 100, and dividing by 5, we find that K = 20. Therefore, Katie has saved $20.
