    ¹/₅                                        20%                                           0.2

    ¹/₄                                        25%                                         0.25

    ¹/₂                                        50%                                           0.5

    ²/₃                                      66.6%                                        0.6

Fraction;

25/100 = 1/4

66.6/100 = 2/3

Percentage

1/5 * 100 = 20%

1/2 * 100 = 50%

Decimal

1/5 = 0.2

25/100 = 0.25

1/2 = 0.5

malfutka [58]

Answer:

  • 865

Step-by-step explanation:

Let the 3-digit number is <u>abc</u> = 100a + 10b + c.

<u>We have:</u>

  • 100a + 10b + c - 100c - 10b - a = 297
  • b = a - 6
  • a = 2c - 2

<u>Simplify the first equation:</u>

  • 99a - 99c = 297
  • a - c = 3
  • a = c + 3

<u>Solve for c by substitution:</u>

  • 2c - 2 = c + 3
  • 2c - c = 3 + 2
  • c = 5

<u>Find a:</u>

  • a = 3 + 5 = 8

<u>Find b:</u>

  • b = 8 - 2 = 6

<u>The number is:</u>

Find the fifth roots of 243(cos 240° + i sin 240°).
Mazyrski [523]

Answer:

See below.

Step-by-step explanation:

Fifth root of 243 = 3,

Suppose r( cos Ф + i sinФ) is the fifth root of 243(cos 240 + i sin 240),

then r^5( cos  Ф  + i sin  Ф )^5 = 243(cos 240 + i sin 240).

Equating equal parts and using de Moivre's theorem:

r^5 =243  and  cos  5Ф  + i sin  5Ф = cos 240 + i sin 240

r = 3 and  5Ф = 240 +360p so Ф =  48 + 72p

So Ф = 48, 120, 192, 264, 336  for   48 ≤ Ф < 360

So there are 5 distinct solutions given by:

3(cos 48 + i sin 48),

3(cos 120 + i sin 120),

3(cos 192 + i sin 192),

3(cos 264 + i sin 264),

3(cos 336 + i sin 336).. (Answer).
