x is 8 less than two times y. What equation represents x?
x = 2y - 8
What is the largest organ in the human body?
The skin
What is looping?
Repeating a statement or series of statements over and over again
What is a model that allows you to test your design?
A prototype
Let the function f be defined by f(x) = 3x - 1 and let the function g be defined by g(x) = x^2. If m is a positive number such that f(7) = g(m) + g(2), what is the value of m?
m = 4
What channels open during repolarization?
Potassium or K Channels
What type of coding language is Java?

Jars A, B, and C each contain 8 marbles. What is the minimum number of marbles that must be transferred among the jars so that the ratio of the number of marbles in jar A to the number in jar B to the number in jar C is 1:2:3?
4. Since jars A, B, and C each contain 8 marbles, there are 24 marbles in the three jars. Let x, 2x, and 3x represent the new numbers of marbles in jars A, B, and C, respectively. Hence, x + 2x + 3x = 24 or 6x = 24, so x = 4.
What is another name for the Krebs Cycle?
Citric Acid Cycle
Why is this not a valid Java statement?
int var = 0.5;
An int variable can only define integers. To define rational numbers, you would need to make the variable a double instead.
What is the difference between an invention and an innovation?
An invention is a completely new idea whereas an innovation is based off of an existing concept or idea
Working alone, Bill takes three times the amount of time to paint a fence that Mike takes. If Bill and Mike work together, they can paint the fence in 2 hours. If Mike works at the same rate as when he worked with Bill, how long would it take Mike working alone to paint the same fence?
2 hours and 40 minutes. If x represents the number of hours it takes Mike working alone to paint the fence, then 3x is the number of hours it takes Bill working alone to paint the fence. So 2(1/x) + 2(1/3x) = 1 gives x = 8/3 hours, and in other words, 2 hours and 40 minutes.
Balance the following reaction.
_Zr2 + _H2O → _ZrO + _H2
1, 2, 2, 2
There are 2 Zirconium atoms on the reactant side, so but a coefficient of 2 in front of ZrO to balance it out. Because we placed a 2 in front of ZrO, there are 2 oxygen atoms on the product side. Balance this out by adding a coefficient of 2 in front of H2O. Because we placed a 2 in front of H2O, there are 4 hydrogen atoms in the reactant side. Put a 2 in front of H2 on the product side to have a total of 4 hydrogen atoms on both sides. Zr2 can be left alone.
What was the origin of the coding language Python?
Monty Python. When he began implementing Python, Guido van Rossum was also reading the published scripts from “Monty Python’s Flying Circus”, a BBC comedy series from the 1970s. Van Rossum thought he needed a name that was short, unique, and slightly mysterious, so he decided to call the language Python.
What is an imaginary line that is used to locate or project the corners, edges, and features of a three-dimensional object onto an imaginary two-dimensional surface?
Projection Line
What is the number of sides of a polygon in which the sum of the degree measures of the interior angles is 4 times the sum of the degree measures of the exterior angles?
10. Sum of the degree measures of exterior angles is 360. S = (n - 2)180 = 4 x 360, where n = number of sides. Solving for (n - 2) = 8 or n = 10.
