Mai runs around a 400 meter track at a constant speed of 250 meters per minute. How many minutes does it take Mai to complete 4
goldfiish [28.3K]

Answer:

6.4 minutes, or 6 minutes and 24 seconds

Step-by-step explanation:

She is running 4 laps, so she is running 1600 meters total.  If she runs 250 meters per minute, divide 1600 by 250 to determine how many minutes it will take...

1600/250  =  6.4

Which is 6 minutes + 0.4 minutes          

*there are 60 seconds in a minute, so the 0.4 represents 40% of another minute.  Multiply 60 by 0.4 to see how many seconds this is...

(0.4)60  = 24 seconds,

So she ran the laps in 6 minutes and 24 seconds

Answer:

36\sqrt{3} -12\pi

Step-by-step explanation:

The area of the shaded portion, we have to calculate.

Now, join C and O to form two right triangles Δ AOC and Δ BOC.

Now, from Δ AOC,  

\tan 60 = \frac{AC}{AO} = \frac{x}{6}

⇒ x = 6√3  

So, area of Δ AOC = \frac{1}{2} \times 6 \times 6\sqrt{3}  = 18\sqrt{3}

Due to symmetry area of Δ BOC will also be 18√3.

Now, area of quadrilateral OACB is 2 × 18√3 = 36√3

Now, area covered by the arc AB about center O will be \frac{120}{360} \times \pi r^{2} = 12\pi

Therefore, the area of the shaded portion is 36\sqrt{3} -12\pi (Answer)
