It is always an acute angle, even if the angle was the minimum 1 degree the complement is still 89 degrees which is still acute
Hey there!!!
Given equation :
... - 3 ( 2x - y ) + 2y + 2 ( x + y )
... -6x + 3y + 2y + 2x + 2y
... -6x + 5y + 2x + 2y
... -4x + 7y
( or )
... 7y - 4x
Hope helps!
Let's assume x= 10.03636........ (1)
Multiply each sides by 100. So,
100x = 1003.63636.......... (2)
Next step is to subtract the equation (1) and (2)
100x - x= 1003.63636- 10.03636
99x= 993.6
99x*10 = 993.6 (By multiplying each sides by 10 to get rid of decimal)
990x = 9936
990x/990 = 9936/990 ( Divide each sides by 990)
x= ( Divide both top and bottom to reduce)
x =
So, 10.03636...... can be represent as 552/55.
Hi,
Concept: This is work & time related problem which can be solved in their inverse proportions.
Let Lisa can do a work in x hours.
Lisa's one hour work = 1 / x
According to the problem, Justin can do the same work in 2x hours.
Justin's one hour work = 1 / (2x)
Now, we shall find both 1 hour work just by adding their 1 hour's work.
Both 1 hour's work = (1 /x) + [1 / (2x)] = 3 / (2x)
Full works time = (2x /3) hours.
Again, according to the problem,
2x / 3 = 8
or, x= 12 hours.
Hence Justin will take 2x = 24 hours to complete work as alone.
