Step-by-step explanation:
Answer
311=0.272727...............
311
= 3011×(110)
= 22+811×110
= 2211×110+811×110
= 2×110+8011×1100
= 210+77+311×1100
= 210+7711×1100+311×1100 or
311=210+7100+1100×(311) ........(A)
Now using value of 311 from (A) within (A)
311=210+7100+1100×(210+7100+1100×(311))
= 210+7100+21000+710000+110000×(311))
Now, if we keep on repeating this endlessly
311=210+7100+21000+710000
Answer:
quantitative manipulation of the independent variable
Time to fit 7500 cars = 7500 * 1.25 hoursnumber of hours available in week = 40 hoursnumber of workers needed = 7500* 1.25 / 40 = 234.4number required = 235
Answer:
The smallest positive number is 8
Step-by-step explanation:
let the smallest positive number = x
45 is a multiple of 9 ⇒ 9 x 5 = 45
the next multiple of 9 after 55 is 63
= 9 x 7
= 63
Thus, x + 55 = 63
x = 63 - 55
x = 8
The greatest common factor of 45 and 63 = 9
Therefore, the smallest positive number is 8
Since b^2 - 4ac = 9-16 < 0
There is no real root present.
