Grace [21]

Answer:

Step-by-step explanation:

After 20 minutes, will all of them working together, they would have typed 13 letters. Then after another 20 minutes, it would be 26. Then 39. But after that is gets tricky. Mary types a letter every 3 minutes. Maggie types a letter every four minutes. and Su Ying types a letter every 10 minutes. After 6 minutes, the total would go to 42 letters. Then another 3 minutes it would be 44 letters. And finally, Su Ying finishes it. Taking a total of 70 minutes, or 1 hour and 10 minutes.

Answer:

x = 10 - 10sqrt(3)/3

Approximately 4.2265 cm

Volume = 1539.6 cm³

Step-by-step explanation:

Let the height be x

V = (20 - 2x)(40 - 2x)x

V = (800 - 80x - 40x + 4x²)x

V = 4x³ - 120x² + 800x

dV/dx= 12x² - 240x + 800 = 0

3x² - 60x + 200 = 0

x = [60 +/- sqrt(60² - 4(3)(200))]/6

x = [30 +/- 10sqrt(3)]/3

x = 10 +/- 10sqrt(3)/3

Approximately,

15.7735 and 4.2265

d²V/dx² = 24x - 240

For max, d²V/dx² < 0

So, x = 4.2265

V = (20 - 2x)(40 - 2x)x

Plug in x = 10 - 10sqrt(3)/3

V = 1539.600718
