Solution: Choice A because we know that the pen increases by $1 or 100% and if we compare the percents of the pen to the other answers, none of them have 100%.
7/63 can be simplified down to 1/9 because if you were to multiply 7 by 9 you would get 63? or an easier way to do it would be to divide 63 by 7
9.99/3=3.33
if one pair =$3.33, then 5 x 3.33= $16.65
The value of y by virtue of the circle description above is; 0.8.
<h3>What is the value of y in the task?</h3>
By definition, a unit circle is a circle whose radius is 1 and has its center at the origin (0,0).
On this note, the value of y can be evaluated as;
1² = (-3/5-0)² + (y-0)²
1 -0.36 = y²
0.64 = y²
±0.8 = y.
However, since point P is in the 2nd quadrant where y is positive, the value of y is 0.8.
