The STEM Club is renting a pavilion at the amusement park. The number attending varies Inversely to the amount they must pay per person for the rental When 25 students attend, they must pay $17 per person. How many students need to attend if they want to pay under $12 per person? A) 34 B) 35 36 D) 37
The inverse variation of the STEM club implies that as the number of students increases, the amount reduces
The number of students is 35
How to determine the number of students?An inverse variation is represented as:
[tex]k = xy[/tex]
Where:
k represents the proportionality constant.
x represents the number of students, and y represents the amount
So, we have:
[tex]x_1 * y_1 = x_2 * y_2[/tex]
This gives
[tex]25 * 17 = x_2 * 12[/tex]
Evaluate the product
[tex]425 = x_2 * 12[/tex]
Divide both sides by 12
[tex]x_2 = 35[/tex]
Hence, the number of students is 35

Three times the complement of an angle is 68° more than the supplement of the angle. Find the angle. Solve for y
[tex]3 \times 22 > 180 - y[/tex]
[tex]66 > 180 - y[/tex]
Plus sides y
[tex]66 + y > 180 - y + y[/tex]
[tex]y + 66 > 180[/tex]
Subtract sides -66
[tex]y + 66 - 66 > 180 - 66[/tex]
[tex]y > 112[/tex]
Also :
[tex]y < 180[/tex]
Thus ;

Answer:
90yd²
Step-by-step explanation:
Area pf trapezium = 1/2 * (sum of parallel sides) * perdendicular distance b/w them.
Here,
Sum of II sides = 11 + 9yd = 20yd
Perpendicular distance = 18 yd
So, area of trapezium is
1/2 * 20yd * 18yd = 180yd²
As the triangle inscribed is right - angled triangle, area of ∆ = 1/2 * 10yd * 18yd = 90yd²
Shaded area = total area - area of ∆
= 180yd² - 90yd²
= 90yd²

A company is making a steel reinforced concrete tunnel to prevent water from coming into the area. They are going to cover it with a protective coating.
They need to know the surface area of the tunnel to purchase the protective coating.
Calculate the surface area of the tunnel
The surface area of the cylinderical tunnel needed to purchase the protective coating is 452.16cm².
How to calculate the surface area?Your information is incomplete. Therefore, an overview of the surface area of a cylindrical tunnel will be given.
Let's assume that the radius is 4cm and the height is 7cm. The surface area of the tunnel will be:
= πr²h + 2πr²
= (3.14 × 4² × 7) + (2 × 3.14 × 4²)
= 351.68cm + 100.48cm
= 452.16cm²

Solve this application problem using a system of equations: 40,000 people attended a ballgame at a stadium that offers two kinds of seats: general admission and reserved. The day's receipts were $425,000. How many people paid $15.00 for reserved seats, and how manypaid $8.00 for general admission?
Answer: 15,000 people paid $15.00 for reserved seats and 25,000 paid $8.00 for general admission.
Step-by-step explanation:
Let x = Number of reserved seats
y= Number of general admission
According o the question:
x + y = 40000 (i)
15x + 8 y = 425000 (ii)
Multiply 8 to equation (i), we get
8x + 8 y = 320000 (iii)
Subtract (iii) from (ii), we get
15x - 8x + 8y - 8y = 425000-320000
⇒ 7x = 105000
⇒ x = 15000 [Divide both sides by 7]
Put this in (i) , we get
15000+y= 40000
⇒ y = 40000-15000
⇒ y= 25000
Hence, 15,000 people paid $15.00 for reserved seats and 25,000 paid $8.00 for general admission.

A city planner wanted to place the new town library at site A. The mayor thought that it would be better at site B. What transformations were applied to the building at site A to relocate the building to site B? Did the mayor change the size or orientation of the library?
The building at site A was translated _______ unit (s)right and _______ unit(s) down, then it was reflected across the x or y (select) - axis.
The size was or was not (select) changed.
The orientation was or was not (select) changed.
Answer:
2 right, 4 down, y-axis
Step-by-step explanation:
Reflection across the y-axis changes the left-right orientation. Reflection across the x-axis changes the up-down orientation. Translation before the reflection can put the figure in a place so that the reflection gives its final location. Translation does not affect the orientation.
__
We observe that the north-south wall is on the west side of the building at Site A, and on the right side at Site B. That means the orientation was changed left-to-right, so reflection was across the y-axis.
If the reflection occurred last, then the position before reflection must have the northeast corner moved from (-3, 5) to (-1, 1). That is, the x-coordinate is increased by 2, and the y-coordinate was decreased by 4.
The building at site A was translated 2 units right and 4 units down; then it was reflected across the y-axis .

1. Crestside Ambulance Service has a van with a 20 gallon fuel tank. To fill the tank required 8
5/10 gallons. How many gallons were in the tank before refueling?
The amount of gasoline that was in the tank before refilling it was 11.5 gallons. Due to the above, it lacked 8.5 gallons to refill it again.
How to calculate how many gallons were missing to fill the tank?To calculate how many gallons were left to refill the tank, you need to know how much gasoline was in the tank.
According to the statement, the tank required [tex]8 \frac{5}{10}[/tex] to fill up, then to know how much gasoline it had we must subtract this amount from the maximum capacity of gasoline that the tank requires as shown below:
[tex]8\frac{5}{10}[/tex] = 8.5 gallons
20 - 8.5 gallons
= 11.5 gallons
Based on the above, the number of gallons in the tank was 11.5 gallons of gasoline.
