Who doesn’t love milk? Our family sure does. Let’s figure out how much milk is consumed each month if each person consumes a fractional amount of milk.

Pre-Algebra on Khan Academy: No way, this isn’t your run of the mill arithmetic. This is Pre-algebra. You’re about to play with the professionals. Think of pre-algebra as a runway. You’re the airplane and algebra is your sunny vacation destination. Without the runway you’re not going anywhere. Seriously, the foundation for all higher mathematics is laid with many of the concepts that we will introduce to you here: negative numbers, absolute value, factors, multiples, decimals, and fractions to name a few. So buckle up and move your seat into the upright position. We’re about to take off!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We’ve also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

Leave a tip for good service: https://paypal.me/jjthetutor It was shown in an example that the electric field due to an infinite line of charge is perpendicular to the line and has magnitude E=frac{lambda}{2pi epsilon_0 r}. Consider an imaginary cylinder with radius r = 0.250 m and length l = 0.400 m that has an infinite…

The figure shows an approximate plot of force magnitude F versus time t during the collision of a 58 g Superball with a wall. The initial velocity of the ball is 34 m/s perpendicular to the wall, in the negative direction of an x axis. It rebounds directly back with approximately the same speed, also…
