Answer: (D) 1.99x + 1.89y = 9.57
Step-by-step explanation: The reason is because equation option D states that for every notepad and pencil, x and y he bought, the total of his bill would equal $9.57.
Area = base * height
Height = area / base
Height = base sin x
Where x = angle between side and the base
Answer:
Therefore,

Step-by-step explanation:
Given:
0° < θ < 360°
tan θ = 3.5134
To Find:
θ in degrees = ?
Solution:
0° < θ < 360° .............Given
Means ' θ ' is between 0° and 360°
.............Given
Therefore,

Also,

So ' θ ' will have Two values for tan θ =3.5134

Therefore,

Answer:
x = 0
Step-by-step explanation:
Given
9 + 5x = 9 + 2x ( subtract 2x from both sides )
9 + 3x = 9 ( subtract 9 from both sides )
3x = 0 ⇒ x = 0
