78/65 x 100 = 120 Therefore, 78 is 120 percent of 65.
Divide 78/72 to give miles per minute. Then multiply by 60 to give miles per 60 minutes or miles per hour. 78 miles in 72 minutes = 65 mph.
72 x 78 = 5616
6. 72/6=12 78/6=13
72/78 = 36/39 = 12/13
Divide both by 13 65/78 = 5/6
Add the seven numbers up then divide the answer by that 7 So 78+65=143 72+60+73=205 86+74=160 Total = 508 508 / 7 = 72.571
78/65 x 100 = 120 Therefore, 78 is 120 percent of 65.
65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80
Divide 78/72 to give miles per minute. Then multiply by 60 to give miles per 60 minutes or miles per hour. 78 miles in 72 minutes = 65 mph.
72 x 78 = 5616
78 = .65 times x78/.65=.65/.65x120 = x
This is an Arithmetic Progression with a first term (a) of 3, and a common difference (d) of 5. The formula for the nth term is a(n) = a + (n - 1)d. Then, 78 = 3 + 5(n - 1) = 3 + 5n - 5 = 5n - 2 Thus, 5n = 78 + 2 = 80 And so, n = 80/5 = 16 The 16th term of this AP is 78.
78 + 65 = 143
72 + 75 + 78 + 72 + 73/5 = 74 is the mean of this data set
6. 72/6=12 78/6=13
72/78 = 36/39 = 12/13
