Solve the equation for y in terms of x <br> 12x + 3y = 12

defon

Answer:

y = 4 - 4x

Step-by-step explanation:

Step 1: Write equation

12x + 3y = 12

Step 2: Subtract 12x on both sides

3y = 12 - 12x

Step 3: Divide both sides by 3

y = 4 - 4x

If a new jacket sells for $30, find the total cost if you were charged 5% sales tax. Round your answer to the nearest cent.

Nady [450]

We would multiply $30 by 5% to first find 5%
5% = 0.05
$30 x 0.05 = $1.50
Now we add that to 30
$30 + $1.50 = $31.50

Your answer is $31.50

A 5'6" person walking down the street notices his shadow. If the angle of elevation from the tip of the shadow to the sun is 60°

madreJ [45]

Answer:

The length of the shadow is 3.17 feet .

Step-by-step explanation:

Given as :

The height of the person walking on street = H = 5'6''

∴ 12" = 1 '

So, 6" = $\dfrac{1}{12}$ × 6 = 0.5'

I.e H = 5.5 feet

The angle of elevation of from tip of shadow to sun = Ф = 60°

Let The length of the shadow = X feet

<u>Now, From figure</u>'

Tan angle = $\dfrac{\textrm perpendicular}{\textrm base}$

Or, Tan Ф = $\dfrac{\textrm AB}{\textrm AO}$

Or, Tan 60° = $\dfrac{\textrm H}{\textrm X}$

Or, Tan 60° = $\dfrac{\textrm 5.5 feet}{\textrm X}$

Or, 1.732 = $\dfrac{\textrm 5.5 feet}{\textrm X}$

Or, X = $\dfrac{\textrm 5.5 feet}{\textrm 1.732}$

∴ X = 3.17 feet

So, The length of the shadow = X = 3.17 feet

Hence, The length of the shadow is 3.17 feet . Answer
