Answer:
i want to help but i dont get this question
Step-by-step explanation:
First, determine the circumference (C) of the circle, the equation,
C = 2πr
Substituting the value or the radius,
C = 2π ( 4) = 8π
The arc length is the product of the circumference and the ratio between the subtended angle and 360. The mathematical expression is already,
S = (8π) x (72 / 360) = 0.8π
Thus, the arc is 0.80π.
Answer:
362880
Step-by-step explanation:
You have to subtract the two people who are already doing something in line so you would do 11-2 which equals 9. Then you would do 9 mPr 9 which gives you an answer of 362,880.
Students = 380
Adults = 150
You can get this by using x = students and y = adults. Then set up a cost equation of:
3x + 4y = 1740
and a total tickets equation of
x + y = 530
Solve using any method.
Divide the new length by the original length:
Scale factor = 2/14
Simplified = 1/7
