In a chemistry experiment, Krystal will pour two different liquid substances into one container. In her first flask, she has 250 milliliters of liquid A. Krystal estimates that 5% of the liquid will be lost when transferring it to the container. In another flask, she has 900 milliliters of liquid B, and she estimates that 9% will be lost when transferring it. If she transfers both liquid A and B to the same container, what is the total volume of liquid in milliliters that will be lost in the transfer, assuming Krystal's estimates are accurate?

The equation above represents the surface area of the ocean, in square meters, covered by jellyfish x years after they've escaped from captivity. The result is influenced by a, the surface area covered by the jellyfish that took part in the initial breakout. If 27 m2 of jellyfish escaped from Glows-R-Us Labs five years ago, while 61 m2 of jellyfish escaped from Frankenstein's Pet Shop two years ago, what is the ratio of the current surface area of the Glow jellyfish to that of the Frankenjellies?
A businessman invests $3000 in Company A. The revenue he earns from this investment can be modeled by 3000(1.1)t where t is the number of years that have passed since his initial investment. At the same time that this businessman invests in Company A, his neighbor, a salesman, starts to make money by selling microchips. The salesman estimates the revenue from his business can be modeled by 700t, where t is the number of years that have passed since he started selling microchips. After 10 years, what is the difference in revenue for these particular business dealings between the two neighbors? Round your answer to two decimal places.
