Which ratio represents the value of sin Q
Volgvan

We know that :

\bigstar \ \ \boxed{\sf{sin\theta = \dfrac{Opposite \ Side}{Hypotenuse}}}

From the figure, We can notice that :

↔   Opposite side of Angle Q is 9 units

↔   Hypotenuse is 15 units

\sf{\implies sinQ = \dfrac{9}{15}}

\sf{\implies sinQ = \dfrac{3}{5}}

Where do i graph?<br> please send picture of your own for me to copy
melomori [17]

Answer:

Step-by-step explanation:

Compound inequality has been given as,

12(2x - 10) + 24 ≥ 48 Or 6x + 15 - 9x ≥ 6

By simplifying it further,

12(2x - 10) + 24 ≥ 48

\frac{12(2x - 10)}{12}+\frac{24}{12}\geq \frac{48}{12}

(2x - 10) + 2 ≥ 4

(2x - 10) + 2 - 2 ≥ 4 - 2

2x - 10 ≥ 2

2x - 10 + 10 ≥ 2 + 10

2x ≥ 12

\frac{2x}{2}\geq \frac{12}{2}

x ≥ 6

6x + 15 - 9x ≥ 6

(6x - 9x) + 15 ≥ 6

(-3x) + 15 ≥ 6

-3x + 15 - 15 ≥ 6 - 15

-3x ≥ -9

3x ≤ 9

x ≤ 3

We have to plot the inequality on a number line

x ≥ 6 Or x ≤ 3
