3 times 7= 21 times three =63
To determine the missing angle you simply subtract the angle you know from 180 because a flat line is 180 degrees. If it is a circle you subtract the number from 360. Hope this helps!
Answer:
10 sqrt 3.
Step-by-step explanation:
sqrt30 = sqrt10 * sqrt 3
so sqrt30 * sqrt10
= sqrt10 * sqrt10 * sqrt3
= 10 sqrt 3.
You need to find the number of permutations of the 6 different letters, taken 3 at a time.

Therefore the sample space is 120 possible outcomes.
Answer:
Step-by-step explanation:
A)
d = r* t Divide both sides by t
d/t = r
r = d/ t
B)
d = 800000
t = 4 hours
r = 800000 / 4
r = 200000 meters/hour
C
r = 200000 meters / hour * [ 1 km / 1000 meters]
r = 200 km / hr
D
I imagine you are more familiar (especially if you live anywhere but the states) with 200 km/ hour. I am very doubtful that any bird can keep that up for 4 hours. 200 km / hour is equal to about 125 miles / hour. There are few places that will allow a car to travel at that speed. You should be using km/hour because you (should) be more familiar with the units.
