A leprechaun places a magic penny under a girl's pillow. The next night there are 2 magic pennies under her pillow. The followin
dezoksy [38]

Answer:

<u><em></em></u>

  • <u><em>32 days</em></u>

Explanation:

Simulate (build a table) the growing of the number of pennies for some nights to figure out the pattern:

First night:          1 penny = 2⁰

Second night:    1 × 2 pennies = 2¹

Third night:        2 × 2 = 2²

Fourth nigth:      2² × 2 = 2³

nth night:           2ⁿ⁻¹

You want 2ⁿ⁻¹ ≥ 2,000,000,000

Which you solve in this way:

  • 2ⁿ⁻¹  ≥ 2,000,000,000

  • 2ⁿ⁻¹ ≥ 2,000,000,000

  • n-1 log (2)  ≥ log (2,000,000,000)

  • n - 1  ≥ log (2,000,000,000) / log (2)

  • n - 1 ≥ 30.9

  • n ≥ 31.9

Since n is number of days, it is an integer number, so n ≥ 32.

Hence, she will have a total of more than $ 2 billion after 32 days.

You can prove that by calculating 2³² = 2,147,483,648.

Alison, Hector, and Myles had a challenge to see who could run the farthest in a month. Alison ran 21 miles. Hector ran 5 times
Leno4ka [110]
Myles ran 2 times what alison ran:
2x21 = 42

Hector ran 5 times as many miles as Myles:
42x5 = 210

therefore Hector ran 210 miles.

The perimeter of a rectangular playground is 86 feet, the width of the playground is 15 feet, what is the length
Gennadij [26K]
The length is 28ft. W=15 so you’d subtract 30 from 86 and get 56. Then divide 56 by 2 and get 28 which is the length. You can check this by adding 15+15+28+27 together and see if it equals 86 which it does.
