Answer:
20π ft
Step-by-step explanation:
Formula: C=2πr, where C is the circumference and r is the radius.
r=10 ft.
C=2*π*10
=20π ft.
Answer:
x + y < 20
5x + 10y ≥ 100
Step-by-step explanation:
The ski club wants at least $100
Student pays $5
Chaperone pays $10
Maximum number of seats = 20
Assumption:
Assumed number of students = x
Assumed number of chaperone = y
Equation:
Maximum number of seats = 20
⇒ x + y < 20
The club wants $100
⇒ 5x + 10y ≥ 100
Y= x + 3
1. Find the gradient(slope)
1 - 7 / - 2 - 4
=1
2. Find the y. Intercept ( c )
Y = x + c
Replace by any of the two coordinates given (4 , 7 )
7 = 4 + c
C= 3
Equation => Y = x + 3
Answer:
C as C^unt
Step-by-step explanation:
It is always negative, because it keeps going down on the number line. Say it is negative 8 minus 5, it would be negative 13, because it adds to the negatives, so it would go deeper into the negatives.
