Answer:
s = 23
Step-by-step explanation:
1. VW ≅ VY is given.
2. XV ≅ VX as it is the same side.
3. ∠WVX ≅ ∠YVX as they are both 90°. ∠WVY is 180° as it is a straight line, so both ∠WVX and ∠YVX are exactly half of that.
Given those three things, you can say that ΔWVX ≅ ΔYVX. Because all corresponding parts of congruent triangles are also congruent, you can be sure that WX ≅ XY. Finally, using that information, you can write an equation and solve for s.

Answer:
The type of method is convenience; he isn't posting advertisements to volunteer(self-selected) and he isn't following an algorithm(systematic), therefore, he's using convenience.
Answer:
22.5 years to the nearest tenth.
Step-by-step explanation:
The equation is
6000 = 4000(1 + 0.018/12)^12t where t = the number of years
(1 + 0.018/12)^12t = 1.5
1.0015^12t = 1.5
Taking logs:
12t log 1.0015 = log 1.5
12t = log 1.5 / log 1.0015
12t = 270.51
t = 22.54 years.
2.5 times three for the three years she didnt cut it would be 7.5 inches so in total her hair would have been 7 1/2 inches longer if she hadnt cut it.
Y+x=31, 150x+225y=5100.
y=-x+31
150x+225(-x+31)=5100
-75x=-1875
x=25 (adult tickets are $25)
31-25= 6 (child tickets are $6)
