Answer:
Hence, the answer is 86.42°.
Step-by-step explanation:
We are asked to find how many degrees is the painted spot turning in 0.75 s.
Let us consider that α denote the angle spot is turning in 0.75 sec.
As in 0.75 sec the height of table top is 12.
Hence we can use the trignometric identity to find the measure of angle α.
as
where P denotes the perpendicular i.e. the height of table top.
and B denotes the base i.e. the number of seconds.
Here P=12 and B=0.75
Hence,
9514 1404 393
Answer:
15/28
Step-by-step explanation:
We can rearrange the problem a bit and make it a little simpler.
1 2/7 - 3/4 = (1 -3/4) + 2/7 = 1/4 + 2/7
= (7+4·2)/(4·7) = 15/28
_____
The sum of fractions can always be found by ...
Answer:
v=1
Step-by-step explanation:
-8 + 5v = -3
add 8 to both sides of the equasion
5v = 5
divide both sides by 5
v = 1
proof:
-8 + 5*1 = -8+5 = -3
