maria [59]

Answer:

8 minutes

Step-by-step explanation:

The amount in the glass after m minutes can be described by ...

a = 4 + 3/2m

We want to find m when a=16, so ...

16 = 4 + 3/2m

12 = 3/2m . . . . . subtract 4

8 = m . . . . . . . . . multiply by 2/3

It will take 8 minutes to fill the glass.

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 :

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

$let \: θ = 72,\pi = 3.14,r = 6.48$

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

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