C/d + 2 = f/g      (subtract 2 from each side)

c/d + 2 - 2 = f/g - 2

c/d = f/g - 2       (multiply d to each side)

c/d*d = d(f/g - 2)

c = d( \frac{f}{g} -2)\ \textless \ -answer

How tall is a building that casts a 73 foot shadow when the angle of elevation of the sun is 29
Ilya [14]
We use trigonometry for this problem. You might have learned about SOH CAH TOA. In right triangles, when given an angle, you can name the three sides of the triangle a certain part: Opposite, Adjacent, and Hypotenuse.

For this problem, we are given the angle and the ADJACENT length (73). We want to find the OPPOSITE side's length.
TOA
We must use the tangent function.

TOA helps us remember this relationship:
tan( theta ) = opposite / adjacent.

Plug in our values:

tan(29 degrees) = opposite / 73

Multiply by 73 to isolate "opposite" and solve for it.

73 * tan(29) = opposite.

Using a calculator, the answer is approximately 40.46 ft.

The price of the Xbox One after tax is $265

<h3><u>Solution:</u></h3>

The price of a Xbox one is $250

The tax on Xbox one is 6%  

Now, the tax of 6% on 250 is calculated as follows:-

=\frac{6}{100} \times 250\\\\=\frac{250 \times 6}{100}=\frac{1500}{100}=15

So, the tax on Xbox one is $15

The total price of box including tax can be calculated by adding price of box and tax on box

<em>Total price of Xbox after tax = actual price of the Xbox One  + Tax on the Xbox One </em>

= $250 + $15

= $265

Hence, the price of the Xbox One after tax is $265

Mario Mario solving the equation shown which value of x will make the equation true?​
Nata [24]

ANSWER

C. 25

EXPLANATION

The given equation is

\frac{1}{5} (x + 20) =  - x + 14 +  \frac{4}{5} x

Multiply through by 5:

5 \times \frac{1}{5} (x + 20) =  - x \times 5 + 14 \times 5 +  \frac{4}{5} x \times 5

Simplify:

x + 20=  -5 x +70 + 4x

Group similar terms:

{x}  + 5x - 4x = 70 - 20

Combine like terms:

2x = 50

Divide through by 2

x = 25

The correct choice is C.
