It's been a long journey: Although I initially wasn't planning on applying for schools this year, in early November (2017), I realized I would pretty much be free until the New Year, so I decided to tac...

Hi Luandato, Before diving into the math for this equation, let's just think about what's going on. We have these two inspectors on the same assembly line. One inspects every 3rd widget and the other every 5th. If we want to know how many were not inspected, then we need to figure out the total that...

Hello again Luandato, The great thing about this question is that once you know the rule for functions, this will become a breeze for you! A quick functions refresher before we tackle this question: "y operations" affect the entire function and are on the outside of the function. E.g. $$2f...

Hi swerve, You seem to have doubled the the area of the two semicircular sections. Here is how I did it: Given: Length = 9 Assume w = width; Diameter = w, therefore, radius = w/2 Area of rectanlge/area of two semicircles = 9/pi Calculations Area of the rectangular section = 9*w = 9w Combined area of...

Hi mbaorbust3, I think you might have missed what the question was actually asking. The questions asks what the REMAINDER of X/5 is. NOT what X is (as such, X = 3 and X = 8 both give us the same answer since they both give a remainder of 3 when divided by 5). How to solve this question using a nifty...

Hi lheiannie07, Start off by identifying the question type: Yes or no We are given no information about a in the prompt, so it could be ANY number. Let's check fact 1: $$\left(1+a\right)^3\ is\ negative,\ so\ \left(1+a\right)^3\ <\ 0$$ As a rule, we know that if a cubed number is negative, its cubic...

Hi M7MBA, Though I am not a "GMAT Expert," I can help you with this problem. First, let's write down what we know: X% of the distance was traveled at 60mph The remaining distance was traveled at 50 mph. We also know that the total trip must add up to 100%, so we can say X% @ 60 mph (100-X)...

Hi Luandato, Okay, so let's start with what we know. Radius, r = 6 ft. Therefore, we can get the area of the circle: $$A= \pi\times r^2$$ $$A =\pi\times 6^2$$ $$A = 36\pi$$ Now, we know that the area of the circle is 3 times the area of the rectangle, so $$A (Rectangle) = \frac{36\pi}{3} = 12\pi$$ T...
