The number of seconds varies directly as the number of minutes. When 300 seconds have passes, 5 minutes have passed. If 480 seco
Stells [14]
Hello!

We know that 1 minute = 60 seconds.

5 minutes = 300 seconds because 60 × 5 = 300

360 seconds would be 6 muinutes. 420 seconds would be 7 minutes. That means 480 seconds = 8 minutes, so 8 minutes have passed.

The exact value of cos5pi/12 is:​
jonny [76]

Step 1: Convert \frac{5\pi }{12}, which is in radians into degrees. To convert it multiply by \frac{180}{\pi }

\frac{5\pi }{12} =\frac{180}{\pi }

900/12

75

Step 2: 75 degrees isn't on the unit circle but 45 degrees and 30 degrees is. Since 45 + 30 = 75 you can use the cosine of 45 and 30 to find the exact value

cos45 = \frac{\sqrt{2} }{2}

cos30 =\frac{\sqrt{3} }{2}

Step 3: Add the cos45 and cos30 to get cos5pi/12

\frac{\sqrt{2} }{2} +\frac{\sqrt{3} }{2} = \frac{\sqrt{2}+\sqrt{3}}{2}

Hope this helped!
