50 of them.
Given the sequence 2, 10, 26, 50, 82, ... We can look at the differences between these numbers: 2 + 8 = 10 10 + 16 = 26 23 + 24 = 50 50 + 32 = 82 and can see that this sequence increments by a value which starts at 2, and itself increments by eight. This means we can describe this sequence with this function: x f(x) = 2 + 8∑x 0 f(x) = 2 + 8( x(x + 1) / 2) f(x) = 2 + 4(x2 + x) f(x) = 4x2 + 4x + 2 f(x) = 2(2x2 + 2x + 1) The next value in the sequence then would be: f(5) = 2(2 * 52 + 2 * 5 + 1) = 2(50 + 10 + 1) = 2 * 61 = 122
26
Each of these equals 650: 1 x 650, 2 x 325, 5 x 130, 10 x 65, 13 x 50, 25 x 26
1 x 26, 2 x 13, 13 x 2, 26 x 1.
50 x 26 = 1,300
set up the ratio, cross multiply and solve 50/1 = 26/x 50x = 26 x = 26/50 x = 0.52 gallons (about a half gallon)
To find 50 percent of a number, multiply the number by 0.5. Therefore, 50 percent of 26 is equal to 26 x 0.5 = 13.
To find 50 percent of a number, multiply the number by 0.5. Therefore, 50 percent of 26 is equal to 26 x 0.5 = 13.
-3(x - 26)(x - 50)
2,500
32 x 50 = 1600 minutes / 60/hour = 26 hours 40 minutes
The factors of 650 are 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, and 650. The factor pairs of 650 are 1 x 650, 2 x 325, 5 x 130, 10 x 65, 13 x 50, and 25 x 26
1 x 650 2 x 325 5 x 130 10 x 65 13 x 50 25 x 26
seventy-five 150.00 x 50/100 = 1.5 x 50 = 75
438 x .50 (50%) = 219
600 = 12 x 50
