It is: (12+42)/2 = 27
Thirty 42 - 18 = 24 24 / 2 = 12 18 + 12 = 30 42 - 12 = 30
Thirty 42 - 18 = 24 24 / 2 = 12 18 + 12 = 30 42 - 12 = 30
32 = 9 42 = 16 12 lies between 9 and 16, so √12 lies between 3 and 4.
Many ways, but the simplest is add the two numbers together and divide the answer by 2. For example, number between 23 and 42. Add them together: 23 + 42 = 65 Divide by 2: 65/2 = 32.5 So 32.5 is [exactly halfway] between 23 and 42.
42 is exactly halfway between 32 and 52.42
3.5
78
It is: 84
Half way between 36 and 42 is (36 + 42) ÷ 2 = 39.
Halfway between 42 and 82 is (42 + 82) ÷ 2 = 124 ÷ 2 = 62.
There are an infinite number of rational numbers between 17% and 42%. 0.1700000001 % is one such.
The numbers between 10 and 30 that have exactly 5 factors are 16 and 25. The number 16 has factors 1, 2, 4, 8, and 16. The number 25 has factors 1, 5, 25, but since it is a perfect square, it also includes the repeated factor of 5. These are the only two numbers between 10 and 30 that have exactly 5 factors.
