Answer: 43feet
Step-by-step explanation:
Perimeter= 135 feet
Since perimeter= 2πr
135 = 2πr
Recall that π = 3.14
135 = 2 × 3.14 × r
135 = 6.28 × r
135 = 6.28r
r = 135/6.28
r = 21.5
d = 2r
d = 2 × 21.5
d = 43 feet
A. Rational
B.Not Rational
C.Rational
D.Rational
The Answer is B
Answer:
C. 7
Step-by-step explanation:
First you have to find the unit rate of this equation
The unit rate is 20 students for every 1 teacher because 40 divided by 2 is 20
so if you do 140 divided by 20 your answer is 7
there are 7 teachers
Answer: C. Ben and Cathy
Step-by-step explanation:
The diagram showing the triangle ABC is shown in the attached photo.
a represents the distance between Ben and Cathy.
b represents the distance between Andy and Cathy
c represents the distance between Andy and Ben,
The unknown angle A is determined by subtracting the sum of angle B and angle C from 180 degrees. This is because the sum of angles in a triangle is 180 degrees.
Angle A = 180 - (55 + 50)
= 180 - 105 = 75 degrees.
75 degrees is the biggest angle and thus, the farthest distance. It corresponds to a, the distance between Ben and Cathy.
