Answer:
<h2>The option B and D are the equations.</h2>
Step-by-step explanation:
Let, the total number of students are x.
The number of students having the ticket is
.
It is given that the number is 20.
Hence,
.
Option B is the equation.
Option D is also the same.
The difference is just, the variable is wriiten in the other side.
Answer:
1/2
Step-by-step explanation:
Answer:
Step-by-step explanation:
a). Total surface area of cylinder is defined by sum of curved surface area and surface area of the top and bottom.
Total surface area = 2πrh + 2πr²
Skateboarders use a half pipe structure which are not closed at the ends.
Therefore, curved surface of the half pipe = 
= πrh
b). If r = 2.5 m and h = 9 m,
Curved surface area of the half pipe = π(2.5)(9)
= 70.69 m²
≈ 71 m²
y = 0x + 3
switch x and y and solve for y if possible
x = 0y +3
x = 3
Not a function because it doesn't pass the vertical line test .
