P = f*s
f +3s = 60
p = (60 -3s)*s = 3(20 -s)*s
This equation describes a parabola that opens downward. The roots of the equation are s=0 and s=20, so the axis of symmetry is s=(0+20)/2 = 10. That is, the vertex (maximum) will be found at s=10.
The second number is 10. The first number is 60-3*10 = 30.
The product is maximized when the first number is 30 and the second is 10.
43
48 - 27(since they left) + 22(since they joined) = 43
21
The value of the home after 21 years is 200,000(1.035)^21=411,886.29
This is the process I would use:
Maddy's = 2x 2x+x=15
Meg's = x 3x=15
x=5
Since Maddy's is 2x, multiply the 5 times 2 and you find that Maddy has 10 stickers.
Answer: WZ
The sequence ABCD has AD as the first and last letters of that sequence, so this pattern applies to WXYZ as well to pull out WZ. Angle A pairs up with angle W because they are both the first letters of the sequences. These angles are congruent from the fact that the parallelograms are similar. The same can be said for angle D and angle Z.
note: WZ is the same as ZW. The order doesn't matter when it comes to labeling segments based on endpoints.
