A small company produces both doll houses and sets of doll furniture. The doll houses take 3 hours of labor to produce, and the furniture sets take 8 hours. The labor available is limited to 400 hours per week, and the total production capacity is 100 items per week. Existing orders require that at least 20 doll houses and 10 sets of furniture be produced per week. Write a system of inequalities representing this situation, where x is the number of doll houses and y is the number of furniture sets. Then graph the system of inequalities.

thank you

When a camera flash goes off, the batteries immediately begin to recharge the flash's capacitor, which stores electric charge given by the following. (The maximum charge capacity is M and t is measured in seconds.)
Q(t) = M(1 - e^-t/a)
(a) Find the inverse of this function and explain its meaning.
t(Q) =

Q(t)=M(1-e^-t/a)
(Q/M)=-e^-t/a
ln(Q/m)=-(-t/a)
ok so now is it
ln(Q/M)=t/a (since it is -e^-t/a so is it -ln(e^-t/a) or is it ln(-e^-t/a)??

okay i didn't really have much room in the question to make it perfectly clear: Prove that if a point lies on the two ends of a line segment, the point lies on the perpendicular bisector of that segment. I get why, I just don't know how to prove it. Thanks so much. Even just a start would be great!

We have nine balls where three of them weigh x grams, three of them weigh y grams and three of them weigh z grams with
x > y > z. Using a balance scale, we want to determine which group each ball belongs to(in other words, whether it weighs x, y or z grams). What is the smallest number of weighings that guarantees us such a finding?
