Answer: v = 793.77 mph
Step-by-step explanation: Linear speed of a circular movement is calculated by using the formula:
v = ω.r
where
ω is angular velocity
r is radius of the path
<u>Angular</u> <u>velocity</u> is the rate of change of the angular position of an object with respect of time, i.e., is how fast an object changes its angular position with time:

The Earth takes 24 hours to complete a rotation, then angular velocity:

0.262 rad/h
At a location 40° north, radius is 3033.5 miles, so:
v = 0.262*3033.5
v = 793.77
<u>At latitude of 40°north, linear speed is </u><u>793.77mph</u>.
Answer:
first on is 2, second is -5, third is 8, and the last one is -147
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
First, multiply the bread cost 2.70 by 2, getting you 5.40.
Next, add 11 for the cost of the caketo 5.40 getting you 16.40
Subtract 16.40 from 20 to get how much money you get for the cookies, getting you 3.60
Divide 3.60 by 3 to find how much money each boy gets, getting you 1.20
Divide 1.20 by .40 to get the number of cookies each boy gets, getting you 3
Let be M the set of the real numbers less thant 69
so we write it as follow M = { x∈R / x ∠ 69}
Answer:
133.3 repeated
Step-by-step explanation:
just divide distance and speed then you get your answer, which is 1.33.3 minutes and if you need to simplify then it would be <u>About</u> 2 hours and 13 minutes
