the probaility of selecting a green shirt
The answer is 9
You divide 143 % 11 to get 13. 13 is the number they make an hour, so if you divide 117 % 13 you will get 9.
2x+2x+60=180 because the angles have to add up to 180
So you have
4x+60=180
4x=120
x=30
a + b = 88 <span>
<span>
</span><span>ab = y
</span><span>
</span><span>a = 88 - b
</span><span>
</span><span>y = (88 - b)*b
</span>
<span>y = -b^2 + 88b
</span><span>
</span><span>Take the derivative and set equal to 0
</span><span>
</span><span>y' = -2b + 88 = 0
</span><span>
</span><span>2b = 88
</span>
<span>b = 44 </span></span>
<span><span>a=44</span></span>
<span><span> both numbers are 44</span></span>
