If 55% had on red shirts, then 100% - 55% had on white shirts. Therefore, 45% had white shirts. 45% is equal to 0.45 and to find the number of spectators who had on white shirts, you multiply 0.45 by 12,000 to get your answer.
The wrestler's weight before he went on his diet is 78 kg
<h3>How to find the y-intercept?</h3>
The formula for slope is;
m = (y2 - y1)/(x2 - x1)
Thus, using two points we have;
m = (93.6 - 85.8)/(3 - 1.5)
m = 5.2
At the start of his diet, time in months = 0 months and so x = 0. Thus;
5.2 = (85.8 - y0)/(1.5 - 0)
5.2 * 1.5 = 85.8 - y0
y0 = 85.8 - (5.2 * 1.5)
y0 = 85.8 - 7.8
y0 = 78 kg
Thus, the wrestler's weight before he went on his diet is 78 kg

1.) 3/4 or .75
2.)A and D?
3.)13,504.60
Hopefully this helped!:)
The answer is 0.79 because you subtract 2.4 with 1.61 which gives you 0.79.
