Speed is the ditance traveled by a certain object given a certain time span. To solve this problem we need to divide the distance by the time given. Before that, the problem asked us to get the speed in terms of miles per minute and we are given a distance of 3 kilometer. We have to convert this to miles. 3km(0.6miles/km) = 1.8 miles. The speed is then 1.8/20 = 0.09mi/min.
Answer:
2x3x5x17
Step-by-step explanation:
Answer:
I think it is the last one.
Apply radical rule
= (10^1/2)3/4x
Apply exponent rule: (a^b)^c = a^bc
= 10^1/2 . 3/4x
Simplify: 1/2 . 3/4x: 3x/8
= 10^3x/8
<span>Since, there are 26 letters in total.</span>
So, total permutations of 26 letters in the 6 letter word will be = 26*26*26*26*26*26 = 26^6
No. of letters that doesn’t include X = 26-1 =25
Permutations of letters that doesn’t include x = 25*25*25*25*25*25 = 25^6
So, total number of permutations that includes x= total permutations of 26 letters- permutation of letters that doesn’t include x
= (26^6 - 25^6) = 64,775,151
