I think the answer would be x= 4/7 y = +-16/7
Answer: Each woman sold her apples at the rate of seven apples for I¢, and 3¢ each for the odd ones which were left over. this made it possible for each to receive the same amount, which is 20¢.
Step-by-step explanation:
given data:
20,
40,
60,
80,
100,
120,
140.
solution.
first woman 20 apples
= 2 + 3 * 6¢.
= 20¢.
second woman 40 apples
= 5 + 5 * 3¢.
= 20¢.
third woman 60 apples
= 8 + 4 * 3¢.
= 20¢.
fourth woman 80 apples
= 11 + 3 * 3¢.
= 20¢.
fifth woman 100 apples
= 14 + 2 * 3¢.
= 20¢.
sixth woman 120 apples
= 17 + 1 * 3¢.
= 20¢.
seventh woman 140 apples
= 20 * 1¢.
= 20¢.
42.50$ ? 21 times 1.25 plus 13 times 1.25 = 42.50?
Answer:
n=3
Step-by-step explanation:
64^(1/3)
Note that the exponent 1/3 given stands for the third root of the integer.
64^(1/3) =4
Check: 4 x 4 x 4 = 64
(By comparison of 64^(1/3) to 64^(1/n) means n= 3)
∜(64^(1/3)) =∜(4) = 1.41421356
The real number is
All the roots are:
1.41421356
1.41421356i
−1.41421356
−1.41421356i
4 is not a perfect 4th power.
