What the answer for 1/4 x 12

coldgirl [10]

Treat 12 as 12/1 that means 12 divided into 1 part
1/4 times 12/1

multiply the top and the bottom becuase

$\frac{x}{y}$ times $\frac{z}{t}$ = $\frac{x times z}{y times t}$ so

1/4 times 12/1=(1 times 12)/(4 times 1)=12/4=3/1=3

the answe ris 3

A triangle has an angle that measures 115°. The other two angles are in a ratio of 3:10. What are the measures of those two angl

serious [3.7K]

Answer: 15º and 50º

Explanation:

The angles in a triangle add up to 180.

180 - 115 = 65

3x + 10x = 13x

13x = 65

x = 5

3x = 15

10x = 50

Obtain the general solution to the equation. (x^2+10) + xy = 4x=0 The general solution is y(x) = ignoring lost solutions, if any

alukav5142 [94]

Answer:

$y(x)=4+\frac{C}{\sqrt{x^2+10}}$

Step-by-step explanation:

We are given that a differential equation

$(x^2+10)y'+xy-4x=0$

We have to find the general solution of given differential equation

$y'+\frac{x}{x^2+10}y-\frac{4x}{x^2+10}=0$

$y'+\frac{x}{x^2+10}y=4\frac{x}{x^2+10}$

Compare with

$y'+P(x) y=Q(x)$

We get

$P(x)=\frac{x}{x^2+10}$

$Q(x)=\frac{4x}{x^2+10}$

I.F= $e^{\int\frac{x}{x^2+10} dx}=e^{\frac{1}{2}ln(x^2+10)}$

$e^{ln\sqrt(x^2+10)}=\sqrt{x^2+10}$

$y\cdot \sqrt{x^2+10}=\int \frac{4x}{x^2+10}\times \sqrt{x^2+10} dx+C$

$y\cdot \sqrt{x^2+10}=\int \frac{4x}{\sqrt{x^2+10}}+C$

$y\cdot \sqrt{x^2+10}=4\sqrt{x^2+10}+C$

$y(x)=4+\frac{C}{\sqrt{x^2+10}}$
