When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to". The solution set for this problem will be all values that satisfy both -3 < x and x < 4.

A quadrilateral PQRS is inscribed in a circle, as shown below

trapecia [35]

Answer:

Option A is correct.

The measure of Arc PQR is 190 degree

Step-by-step explanation:

Given a cyclic quadrilateral PQRS is inscribed in a circle as shown in figure.

Given: $\angle PQR = 85^{\circ}$

An intercepted arc measures twice the intercepted angle.

The intercepted angle in the given figure is Arc PQR = $2 \cdot \angle PSR$ ......[1]

First find the $\angle PSR$ ;

A quadrilateral is cyclic if and only if opposite angles sum to 180°.

then;

$\angle PQR+\angle PSR =180^{\circ}$

Substitute the value of $\angle PQR = 85^{\circ}$ in above equation we get;

$85^{\circ}+\angle PSR =180^{\circ}$

Simplify:

$\angle PSR =180^{\circ}-85^{\circ} =95^{\circ}$

Now; to find the measure of arc PQR ;

[1] ⇒ Arc PQR = $2 \cdot \angle PSR$ = $2 \cdot 95 =190^{\circ}$

Therefore, the measure of arc PQR is 190 degree.

Lori works as a cartoonist for a teen magazine.The time she spent sketching is given by the equation m=12s, where mis the number

Vera_Pavlovna [14]

Answer:

Lori spends 9 minutes on sketching $\frac{3}{4}$ th of a sketch.

Step-by-step explanation:

Given equation:

$m=12\ s$

where $m\rightarrow$ number of minutes Lori spends on sketching

and $s\rightarrow$ number of sketches Lori makes.

We need to calculate the time spent by Lori in sketching $\frac{3}{4}$ of a sketch.

So we know the value of $s=\frac{3}{4}$ as $s$ represents number of sketches and in this situation Lori has sketched only a fraction of a painting.

So we plugin $s=\frac{3}{4}$ in the equation and calculate $m$ which is time spent by Lori sketching $\frac{3}{4}$ th of a sketch.

$m=12\ \frac{3}{4}$

$m=\frac{36}{4}$

∴ $m=9$ minutes (Answer)

∴ Lori spends 9 minutes on sketching $\frac{3}{4}$ th of a sketch.

PLEASE HELP! Two complementary angles measure (12x - 18) and (5x +23). What is the measure of the smaller angle? (1) 5 (2) 42 (3

FromTheMoon [43]

Answer:

Step-by-step explanation:

firstly, what are complementry angles.complementary angles are angles that su

m up to 90°

(12x-18)+(5x+23)=90

collecting like terms

12x+5x+23-18=90

17x-5-90=0

17x-95=0

17x=95

divide through by 17

x=5
