John is 1 8 meter shorter than Paul, and Paul is 0.25 meter taller than Andrew. If John’s height is 1 3 4 meters, what is Andrew

9966 [12]

Answer:

Andrew's height is $1\frac{5}{8}$ meters

Explanation:

We know that John's height is $1\frac{3}{4}$ meters

We are given that:

John is $\frac{1}{8}$ meters shorter than Paul

This means that:

Paul's height = John's height + $\frac{1}{8}$

Paul's height = $1\frac{3}{4} + \frac{1}{8} = 1\frac{7}{8}$ meter

We are given that:

Paul is 0.25 meters taller than Andrew

This means that:

Andrew's height = Paul's height - 0.25

Andrew's height = $1\frac{7}{8} - 0.25 = 1\frac{5}{8}$ meters

Hope this helps :)

Which answer is the solution set in simplest form?

ANTONII [103]

In this question there is 1 equation with 1 unknown variable. So it is absolutely possible to find the value of the unknown variable "x".
(4x - 1)/3 = 7/1
4x -1 = 7 * 3
4x - 1 = 21
4x = 21 + 1
4x = 22
x = 22/4
= 11/2
So the value of the unknown variable x is 11/2. So the correct option is option "d". Hope i have answered your question correctly and helped you to understand the method by which these problems should be done.

Solve the following differential equation: (2x+5y)dx+(5x−4y)dy=0 *Hint: they are exact C=.

Tpy6a [65]

Answer with Step-by-step explanation:

The given differential equation is

$(2x+5y)dx+(5x-4y)dy=0$

Now the above differential equation can be re-written as

$P(x,y)dx+Q(x,y)dy=0$

Checking for exactness we should have

$\frac{\partial P}{\partial y}=\frac{\partial Q}{\partial x}$

$\frac{\partial P}{\partial y}=\frac{\partial (2x+5y)}{\partial y}=5$

$\frac{\partial Q}{\partial x}=\frac{\partial (5x-4y)}{\partial x}=5$

As we see that the 2 values are equal thus we conclude that the given differential equation is exact

The solution of exact differential equation is given by

$u(x,y)=\int P(x,y)dx+\phi(y)\\\\u(x,y)=\int (2x+5y)dx+\phi (y)\\\\u(x,y)=x^2+5xy+\phi (y)$

The value of $\phi (y)$ can be obtained by differentiating u(x,y) partially with respect to 'y' and equating the result with P(x,y)

$\frac{\partial u}{\partial y}=\frac{\partial (x^2+5xy+\phi (y)))}{\partial y}=Q(x,y))\\\\5y+\phi '(y)=(5x-4y)\\\\\phi '(y)=5x-9y\\\\\int\phi '(y)\partial y=\int (5x-9y)\partial y\\\\\phi (y)=5xy-\frac{9y^2}{2}\\\\\therefore u(x,y)=x^2+10xy-\frac{9y^2}{2}+c$
