Ok so this can get tricky, it is basically just asking for you to perform many unit conversions. I'll try to simplify it for you here while still maintaining the explanation. If you have any questions about this process feel free to message me.
3 yards = ____ miles (conversion factor is 1760 because there are 1760 yards in a mile)
3/1760 = 0.017 miles,
Now we just need to convert seconds to hours.
1 second is how many mins, then how many mins in an hour?
360 seconds in an hour.
Ok now we just need to combine these two pieces of info,
0.017/360 = 4.72222 miles per hour. Thus 4.72 is the answer.
Discounting the first fly, the second two chances it is a chance of 1/2
1/2 * 1/2 = 1/4 = 0.25
The required roots of given equation are ~
The solution is in attachment ~
secA=√2
secA=sec45
A=45°
3cos²45+5tan²45/ 4tan²A-sin²45
= 3(1/√3)²+5(1)² / 4(1)²-(1/√2)²
=3/2+5/4-1/2
=13/7
In a Fibonacci Sequence, the following applies:
1,1,2,3,5,8 etc.
Where the following term is a sum of the 2 previous terms.
Relate this to the terms in your question:
1, 1, 2, 5, 8
Goes to:
Y-x, x, y, x+y, x + 2y
Since to get y you add the 2 previous terms
y-x + x = y
y + x = y + x
x + y + y = x + 2y
Hope this helps you :)
You used multiplication of 2 terms which is where you went wrong.
