Answer:
120°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for third angle
third angle = 180° - (20 + 40)° = 180° - 60° = 120°
Answer:
(-1, 1), (-1, 2), (0, 1)
Step-by-step explanation:
It appears as though letter designations have become confused. If not, your question answers itself, as a, b, c are given and you're asking for a, b, and c.
___
Reflecting the given points across the line y=-x transforms them like this:
(x, y) ⇒ (-y, -x)
That is, you swap the coordinates and negate them both. The result will be as shown above and in the attachment.
The answer would be it ~linear~
Hope this helps
Have a great day/night!
Answer:
Re= 5*10^5
Step-by-step explanation:
The numbers are not totally clear as they repeat each other. Under this consideration I will assume the closest values according to the advertised.
r=0.5m
V=1m/s (or) V=11m/s
We know that Reynolds number is given by,
Or for the another velocity
Answer: 1/5 or 0.2 in decimal form.
Explanation:
There are 60 seconds in a minute. We know the river flows 12 ft per 1 minute. So in order to find the rate per seconds, divide: 60/12. You get the answer: 1/5 or 0.2 in decimal form.
