A proportion refers to a relationship between two numbers, not four.
64 and 81
41, 43, 47, 53, 59, and 61
The composite numbers between 50 and 65 are 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65
GCF of 40 and 64 is 8.
It is 64.
40:64 = 50:80
-50
41, 43, 47, 53, 59, and 61
64 and 81 are squares of whole numbers. 64 is the square of 8 (8x8=64) and 81 is the square of 9 (9x9=81).
40% off 64 = 64 - (0.40 x 64) = 38.4
GCF of 40 and 64 is 8.
There are 41 composite numbers from 50 to 100. Some of the composite numbers from 50 to 100 are 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, and 70.
40/64 62.5%
4, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
32/50 x 100 = 64. Therefore, 32 is 64 percent of 50.
Firstly: X + Y = 64 Secondly: X - 2Y = -8 Therefore X = 2Y - 8 Now, we can put that value of X into the first equation and we get 2Y - 8 + Y = 64 Which reduces to 3Y = 72, and that gives Y = 24. So, if X + 24 = 64 then X = 40. Putting that into the second equation we get: 40 - 2(24) = 40 - 48 = -8
Using the tn formula, t1=56, the last number, tn=497, and d=7. Therefore, 497=56+(n-1)7. 448=7n, and n=64. So there are 64 numbers between 50 and 500 that are divisible by 7.
