<h3>Answer: 10.99</h3>

Work Shown:

Angle B = 20 is the reference angle

AC = 4 is the side opposite this reference angle

BC = x is the unknown adjacent side

tan(angle) = opposite/adjacent

tan(B) = AC/BC

tan(20) = 4/x

x*tan(20) = 4

x = 4/tan(20)

x = 10.9899 approximately (make sure your calc is in degree mode)

x = 10.99 rounding to two decimal places

BC = 10.99

Answer:

<h2>6 is the Answer.</h2>

Step-by-step explanation:

A fraction consists of two parts the top number and the bottom one.

Think of the top number as the count and the bottom as the size indicator. So you have:

countsize indicator −−−−−−−−−−→proper names numeratordenominator

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Consider the action example of dividing 3 into 6.

We can do this division directly because their size indicators are the same. That is, we have: 61÷31. People do not normally write it this way but it is correct.

To directly divide the counts the size indicator must be the same

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So we need to see how many of 18 will fit into 34

We can not do this directly in one operation as the size indicators are not the same.

Lets make the size indicators (denominators) the same

Multiply by 1 and you do not change the value but

1 comes in many forms.

[34×1]÷18 → [34×22]÷18

[3×24×2]÷18 → 68÷18

Now that the size indicators (denominators) are the same we can just divide the counts (numerators)

countsize indicator→[68÷18]=6÷1=6

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I could explain more showing the connection between this and the shortcut method but what I have shown you will do for now.

What is the slope of 4x-5y=-5
gavmur [86]

Hey there!!

In order to find the slope, let's convert this equation which is in a standard form to a slope-intercept form.

Slope intercept form:

<em>y = mx + b </em>

We have two things to remember:

  • 'm' in the equation stands for slope.
  • 'b' in the equation resembles y-intercept.

Given:

4x - 5y = -5

The main idea:

  • We will have to isolate 'y'

First, let's subtract 4x on both sides:

4x - 5y - 4x = -4x -5

-5y = - 4x - 5

Now let's divide both the sides with -5

-5y/-5 = (-4x/-5) + (-5/-5)

y = (4/5)x + 1

Now, we got the slope intercept form and the coefficient of 'x' would be the slope.

<u><em>Hence, the slope of the line is '4/5' </em></u>

Hope it helps!
