Step-by-step explanation:
The desired arc length is 100 miles and the desired change in direction is 20 degrees. The equation that describes arc length as a function of the radius is:
Applying the given values:
A radius of 286.48 miles should be used.
Answer:
v=2
Step-by-step explanation:
8/v+1/2=7/v
1/2=8/v-7/v
1/2=1/v
(1/2)v=1
v=1/1/2
v=1*2/1
v=2
Answer:
Step-by-step explanation:
120/3= is 40mph
200/40= 5
At 40 mph it will take 5 hours.
Answer:
23/24
Step-by-step explanation:
7/12 + 3/8
The common denominator is 24
7/12 *2/2 = 14/24
3/8 *3/3 = 9/24
Add them together
14/24+9/24 =23/24
The first one is negative one property of division, I think.
The second one is commutative property of multiplication.
