You know that cos(x) = CA/BA = 9/14
.. x = arccos(9/14) ≈ 50° . . . . . . . . selection 3
Let x = number of white marbles and y = number of yellow marbles.
x + y = 57 => x = 57 - y
Also, x = 3 + 5y
Substitute x for y.
57 - y = 3 + 5y => 57 - 3 = 54 = 6y
So, y = 9
Since x (our answer) = 3 + 5 (9),
x = 48.
Check: 48 + 9 = 57 total
Answer:
(0,-2) and (3,0)
Step-by-step explanation:
Answer:
Yes.
Step-by-step explanation:
If we wrote the equation down
7=4-(-3)
Then, we do keep, change, change
7 = 4+3
Y = 7
The equation is true, so that means the points are.
Answer:
311.25 hours ; almost 13 days
Step-by-step explanation:
actually you will not able to drive a car all the way around the earth (the Pacific and Atlantic oceans are really big).
but According to the calculation it would take you around 311.25 hours ( almost 13 days) to drive the 24,900 miles around the circumference of the earth at its widest point (the equator).
because we know ,
t=s/v
=(24,900/80)hours [ s= the circumference of the earth]
=311.25 hours [v=Velocity]
