Answer:
6 hours
Step-by-step explanation:
70 ÷ 4 = 17.5 ----- divide to find out how many miles she travels per hour.
Samantha is driving at 17.5 mph
105 ÷ 17.5 = 6 ----- divide to find out how long it will take to travel that distance.
distance ÷ time = speed
distance ÷ speed = time
Answer:
hour hand = 7.5 x 2 for the diameter. C = 2(pi)(15) = approx. 94 centimeters. Minute hand = 9.5 x 2 = 19, C = 2(pi)(19) = approx. 119 centimeters

Answer:
The lines are parallel
Step-by-step explanation:
If they have no solution that means that they never intersect which akes them parallel
Answer:
b = 45 / 4 = 11 1 /4.
Step-by-step explanation:
We are dealing with a (30,60,90)-triangle, therefore z = 15 sqrt(3) / 2. So as well b = (15 sqrt(3) / 2) sqrt(3) / 2 = 45 / 4.
