ANSWER
{1, 4, 9, 16, 25, 36, 49, 64}
EXPLANATION
The perfect square integers between 1 and 80 inclusive are obtained by squaring the natural numbers from 1 to 8
The square of the next number does not fall within the given range.
Therefore "The perfect square integers between 1 and 80 inclusive" are
{1, 4, 9, 16, 25, 36, 49, 64}
Answer:
6 and 14
Step-by-step explanation:
The numbers are in the ratio 3 : 7 = 3x : 7x (x is a multiplier )
adding 1 to smaller number is 3x + 1 and 7 to the larger is 7x + 7, then
3x + 1 : 7x + 7 = 1 : 3
Expressing the ratio in fractional form
=
( cross- multiply )
3(3x + 1) = 7x + 7
9x + 3 = 7x + 7 ( subtract 7x from both sides )
2x + 3 = 7 ( subtract 3 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Thus the numbers are
3x = 3(2) = 6
7x = 7(2) = 14
