Find the value of y.

Phoenix [80]

$\boxed{y=6\sqrt{3}}$

<h2>Explanation:</h2>

For a better understanding of the problem I've built up two triangles from the given triangular shape. So these two triangles are similar. Therefore, we can solve this problem by using ratios and corresponding sides in this way:

$\frac{x}{3}=\frac{12}{x} \\ \\ x^2=36 \\ \\ x=\sqrt{36} \\ \\ x=6$

But our goal is to find y. Let's call w the height of the small triangle, then:

$w=\sqrt{6^2-3^2}=3\sqrt{3}$

Applying the concept of ratios again:

$\frac{y}{w}=\frac{x}{3} \\ \\ y=w \left(\frac{x}{3}\right) \\ \\ y=3\sqrt{3}\left(\frac{6}{3}\right) \\ \\ \boxed{y=6\sqrt{3}}$

WORDED QUADRATIC EQUATION!!! PLS HELP <br><br> MOSTLY NUMBER 5 PLS

pav-90 [236]

Answer:

7,11

Step-by-step explanation:

The width is x. x+4= the length. The area is side times side, so it’s

x × (x+4) = 77

We can simplify this to:

x × x + x × 4 = 77

x^2 + 4x = 77

x^2 + 4x - 77 = 0 This is a quadratic equation. So we can solve using the quadratic formula:

x = $\frac{-4\pm\sqrt{4^2-4\cdot1\cdot-77}}{2\cdot1}$ ->

$\frac{-4\pm18}{2}$

$\frac{14}{2} \implies7$

That’s the positive solution and that’s x, the width. So the width is 7 and the length is 7+4=11

If a = 0.3 and b =0.5, what is the value of a+b?

Alborosie

Answer=

D

Step-by-step explanation

because of the dot/line at the top of the number it means it is a continuous same number

for example, 0.3 with a dot/line on top means it is 0.333333...

so 0.55...+0.33...=0.88...

and as it is a decimal that is in the range of 1-100 its like a percentage so it is 88/100

The question is an illustration of angles on a straight line

The value of x is 25.4

<h3>How to determine the value of x</h3>

In the figure, angles 1 and 2 are angles on a straight line

Where:

Angle 1 = 4x - 8
Angle 2 = 3x + 10

So, we have:

$4x - 8 + 3x + 10=180$

Collect like terms

$4x + 3x =180 - 10 + 8$

$7x =178$

Divide through by 7

$x =25.4$

Hence, the value of x is 25.4
