Find the length of arc RQ. Use 3.14

Helen [10]

Answer:

The length of arc PQ is 8.1 inches.

Step-by-step explanation:

First, you have to find the angle of POQ. Given that total angles in a circle is 360°, so you have to subtract to get ∠POQ :

$73 + 150 + 65 + ∠POQ = 360$

$288 + ∠POQ = 360$

$∠POQ = 360 - 288 = 72$

Next, you have to apply length of arc formula, Arc = θ/360×2×π×r where θ represents the angle of arc and r is the radius of circle :

$arc = \frac{θ}{360} \times 2 \times \pi \times r$

$let \: θ = 72,\pi = 3.14,r = 6.48$

$arc = \frac{72}{360} \times 2 \times 3.14 \times 6.48$

$arc = 8.1 \: inches \: (near.tenth)$

Match the inequality with its line graph.

Flura [38]

Answer:

Here, answer is given in form of 4 figure labelled with inequality

Step-by-step explanation:

Given inequality are

A). $2x>(-6)$

B). $6+x\leq 3$

C). $x-4$

D). $-x-5\leq (-2)$

For matching with givens graph:

Simplifying...

A). $2x>(-6)$

Divide 2 on both sides

$x>(-3)$

B). $6+x\leq 3$

Add (-6) on both side.

$6+x+(-6)\leq 3+(-6)$

$x\leq(-3)$

C). $x-4$

Add (4) on both side.

$x-4+4$

$x$

D). $-x-5\leq (-2)$

Multiple (-1) on both side

$+x+5\geq (+2)$

Note : Change of inequality sign due to multipication of negative number

Add (-5) on both side.

$x\geq (-3)$

Here, Answer is given in form of 4 figure labelled with inequality
