How do you solve 8/n=3/(n-5)?
Jan 18, 2017
$n = 8$
Explanation:
Given:
$\frac{8}{n} = \frac{3}{n - 5}$
Multiply both sides by $n \left(n - 5\right)$ to get:
$8 \left(n - 5\right) = 3 n$
That is:
$8 n - 40 = 3 n$
Add $40 - 3 n$ to both sides to get:
$5 n = 40$
Divide both sides by $5$ to find:
$n = 8$ | {} |

# Where did the description that acids are sour and bases are bitter come from?
Where did the description that acids are sour and bases are bitter come from? With Arrhenius definition, those descriptions may have fit acids and bases, but with the Lewis definition, I guess they would not really apply.
For example, $\c... | {} |
# Soap bubbles and the isoperimetric problem
During a moment of reflection last summer, I momentarily thought about the shape of balloons and bubbles in general. I wondered why of all the possible shapes a balloon could have, why the sphere? If there was a reason why the bubble converged to the shape of a sphere I wan... | {} |

## Introduction
The Franka-Emika Panda is a high-performance 7DOF robot arm. It is produced by a Munich-based startup with a design heritage traceable to Germany’s DLR institute which also found its way into KUKA’s LWR robot series. The Panda robot’s joints are sophisticated mechatronic syste... | {} |

# 11.1: Introduction
Consider a plane wave propagating along the z-direction in vacuum, and polarized with its electric vector along the x-axis: its magnetic field vector must be directed along the y-axis. Now introduce two infinitely conducting metal planes which block off all of space except th... | {} |

1. The problem statement, all variables and given/known data
A parachutist of mass 80 kg approaches the ground at 5 m/s. Suppose that when he hits the ground, he decelerates at a constant rate (while his legs buckle under him) over a distance of 1 m. What is the... | {} |
Clarification on the definition of inner product
An inner product is a generalization of the dot product. In a vector space, it is a way to multiply vectors together, with the result of this multiplication being a scalar.
More precisely, for a real vector space, an inner product $\langle \cdot,\cdot \rangle$ satisfie... | {} |

In this talk I will describe the orthogonality of some families of $$q$$-polynomials for almost all the values of their parameters. I also present the last res... | {} |
# Sous-variétés lagrangiennes monotones
Abstract : The monotonicity condition for Lagrangian submanifolds was introduced by Oh in 1993. This is a relative version of a condition defined by Floer for symplectic manifolds. These conditions make possible the definition of Floer type homologies, especially of the Lagrangi... | {} |

Cox Proportional Hazards Model Introduction. Menu location: Analysis_Survival_Cox Regression. Here, we’ll disscuss three types of diagonostics for the Cox model: Testing the proportional hazards assumption. And, we don’t have to assume that 0(t) follows an expo-nential model, or a Weibull model, or any other particular... | {} |
