<span>the line over the 28 means the 28 repeats forever.
1.282828.... and so on
let x be the rational number 1.28...
we can use this trick:
100*1.282828....= 128.282828... (the decimal 28 part repeats)
100x = 128.28...
next:
100x - x = 128.282828... - 1.282828...
the .282828... part will be subtracted away
99x = 127
divide both sides by 99 to get
x= 127/99</span>
Answer: C
Explanation: tan = opposite/adjacent. 8 is the opposite length from angle B and 15 is the adjacent length from angle B. so tan(B) = 8/15
Check the picture below.
notice the reflected gray line on the red one over the y=x line, the slope of either line across the y=x line is simply the other's upside-down.
Answer:
y=0
Step-by-step explanation:
m=y change in y/change in x
2+3/-2+2 = 5/0
<span>58%
The sum of all the probabilities has to be 100%. In tennis, because there's no time limit, a match will always result in a win or a loss. Since Garry has won 42% of his games, that means that he's lost 100% - 42% = 58% of his games. And if you assume his win/loss ratio is reflective of his future games as well as his past games, then he as a 58% chances of loosing his next match.</span>
