Question:

Martin uses 5/8 of a gallon of paint to cover 4/5 of a wall. what is the unit rate at which Martian paints in walls per gallon

Answer:

0.78125 walls per gallon

Step-by-step explanation:

Given

$Paint = \frac{5}{8}\ gallon$

$Wall = \frac{4}{5}$

Required

Determine the unit rate

This is calculated as:

$Unit\ Rate = \frac{Wall}{Paint}$

Substitute values for wall and paint

$Unit\ Rate = \frac{5/8}{4/5}$

Simplify:

$Unit\ Rate = \frac{5}{8}/\frac{4}{5}$

Change to *

$Unit\ Rate = \frac{5}{8}*\frac{5}{4}$

$Unit\ Rate = \frac{5*5}{8*4}$

$Unit\ Rate = \frac{25}{32}$

$Unit\ Rate = 0.78125$

<em>Hence, the unit rate is: 0.78125 walls per gallon</em>

Find a formula for the sum S of the solutions of the quadratic equation ax²+bx+c=0 .

Deffense [45]

Answer:

$S = -\frac{b}{a}$

Step-by-step explanation:

Given a second order polynomial expressed by the following equation:

$ax^{2} + bx + c, a\neq0$

This polynomial has roots $x_{1}, x_{2}$ such that $ax^{2} + bx + c = (x - x_{1})*(x - x_{2})$ , given by the following formulas:

$x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}$

$x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}$

$\bigtriangleup = b^{2} - 4ac$

In this problem, the sum S of the solutions of a quadratic equation is:

$S = x_{1} + x_{2}$

$S = \frac{-b + \sqrt{\bigtriangleup}}{2*a} + \frac{-b - \sqrt{\bigtriangleup}}{2*a}$

They have the same denominators, so we can keep the denominators and sum the numerators.

$S = \frac{-b + \sqrt{\bigtriangleup} - b - \sqrt{\bigtriangleup}}{2a}$

$S = \frac{-2b}{2a}$

$S = -\frac{b}{a}$
