<span>m/9 - 17=21
------------
Simplify
1/9m - 17 = 21
----------------
Add 17 to each side
1/9m-1</span><span><span>7</span>+17</span>=<span>21+<span>17
1/9m = 38
------------------------
Multiply each side by 9
9 * (1/9m) = 38 * 9
m = 342 is your answer</span></span>

Okay. The question is m/9 - 17 = 21. First off, we will add 17 to both sides. -17 + 17 cancels out. 21 + 17 is 38. That leaves m/9 = 38. Multiply each side by 9 to isolate the m, because m is the numerator and 9 is the denominator. m/9 * 9/1 cancels out. 38 * 9 is 342. Let's check this. 342/9 is 38. 38 - 17 is 21. 21 = 21. There. x = 342.

Find the area of following rhombuses. Round your answers to the nearest tenth if<br> necessary.

Answer:

$Area =55.4ft^2$

Step-by-step explanation:

Given

The attached rhombus

Required

The area

First, calculate the length of half the vertical diagonal (x).

Length x is represented as the adjacent to 60 degrees

So, we have:

$\tan(60) = \frac{4\sqrt 3}{x}$

Solve for x

$x = \frac{4\sqrt 3}{\tan(60)}$

$\tan(60) = \sqrt 3$

So:

$x = \frac{4\sqrt 3}{\sqrt 3}$

$x = 4$

At this point, we have established that the rhombus is made up 4 triangles of the following dimensions

$Base = 4\sqrt 3$

$Height = 4$

So, the area of the rhombus is 4 times the area of 1 triangle

$Area = 4 * \frac{1}{2} * Base * Height$

$Area = 4 * \frac{1}{2} * 4\sqrt 3 * 4$

$Area =2 * 4\sqrt 3 * 4$

$Area =55.4ft^2$

A triangle has a perimeter of 77 centimeters. Each of the two longer sides of the triangle is three times as long as the shortes

leva [86]

Answer:

a = 33cm

b = 33cm

c = 11cm

Step-by-step explanation:

Let us say that the sides of the triangle are <em>a, b and c</em>

The perimeter of a triangle can be calculated by adding all three sides of the triangle.

Perimeter = <em>a + b + c</em>

<em />

Let side <em>c</em> be the shortest side of the triangle.

From the statement "Each of the two longer sides of the triangle is three times as long as the shortest side" we can have that

<em>a = 3c and b = 3c</em>

We can input these values into the perimeter of the triangle

Perimeter = <em>3c + 3c + c = 77</em>

<em>Perimeter = 7c = 77</em>

<em>c = 11</em>

The shortest side, c is = 11 cm

side a is 3 X 11 = 33cm

side b = 3 X 11 = 33 cm
