Answer:
4 weeks
Step-by-step explanation:
Julie starts out $100 behind Amanda, but earns $25 per week more than Amanda. That means she will catch up after 100/25 = 4 weeks.
Answer:
Her average speed is 48 miles per hour.
Step-by-step explanation:
1. You have to do order of operations in reverse (PEMDAS in reverse)
2. Divide 36 by 3/4 which would be to multiply by the reciprocal (multiplying 36 by 4/3)
3. The answer would then be r=48
Answer:
B. (−2, 3)
Step-by-step explanation:
To find the midpoint of a segment, add the x-coordinates of the endpoints and divide by 2. Add the y-coordinates of the segments and divide by 2.
x: (5 + (-9))/2 = -2
y: (-1 + 7)/2 = 3
Midpoint: (-2, 3)
Answer: B. (−2, 3)
Circumference of a circle:
C = 2 r π;
Length of an arc:
L = r π α / 180°
L = r π · 30° / 180° = r π /6
r π /6 : 2 r π = 1/6 : 2 = 1/12
Answer: A ) 1/12
False
I think that’s right because three times 5 is 15 increased by four is 19 not -8 so...
