Answer:

43 9/10 miles

Step-by-step explanation:

2(1 3/4) + 2(20 1/5) = 2(7/4) + 2(101/5) = 14/4 + 202/5 = 7/2 + 202/5

common denominator will be 10

7(5) = 35

202(2) = 404

35/10 + 404/10 = 439/10 = 43 9/10 miles

How many ways are there to rearrange the letters ALIVE in such a way that the word EVIL is not contained in the resulting word
Sergio [31]

Answer: 118 combinations.

Step-by-step explanation:

In ALIVE we have 5 letters, rearranging it we have the possible options of:

5 options for the first letter.

4 options for the second letter, as one was already chosen for the first one

3 options for the third letter, as 2 were already chosen.

2 options for the fourth letter.

1 option for the last letter.

The total number of combinations will be equal to the product of the numbers of options for each letter, then we have:

5*4*3*2*1 = 120 combinations.

And the combinations where the word EVIL is formed are:

AEVIL

EVILA

2 combinations, then the total number of combinations such that the word evil is not formed are:

120 - 2 = 118 combinations.
