Step-by-step explanation:
Circumference = 750 m / 3
Circumference 250 m
Circumference = pi * D where pi = 3.1415926 and D is the diameter in meters
Solving for the diameter
250 m = pi * D
D = 250 m / pi
D = 79.58 m is the diameter of the circular field
Solving for the radius
r = 1/2 D where r is the radius of the circular field
r = 39.59 m is the radius of the circular field
Answer: 20%
Step-by-step explanation:
The 150 students in the marching band and 30 of the students play the trumpet. To get the percentage of students that play the trumpet, we divide 30 by 150 and then multiply by 100. This can be written as:
= 30/150 × 100
= 0.2 × 100
= 20%
The percentage of students that play the trumpet is 20%
Since Charles runs a 1/4 mile in 10 minutes, and 1/4 goes into 1 1/2 6 times, the answer is 10*6, which is 60.
Answer:
A
Step-by-step explanation:
slope of the given line: -a/b
-4/-2 = 2
realtionship between the slopes of two perpendicular lines:
m = -1/m
slope of the second line
-1/2
line
y-y1 = m(x-x1)
y - 6 = -1/2(x-4)
y = -1/2x + 2 + 6
y = -1/2x +8
