Answer:
The number of 3-digit phone prefixes that do not start with 0 or 1, but contain 0 or 1 as the middle digit is 160.
Step-by-step explanation:
The phone prefix for any area is of the form <u>X</u> <u>X</u> <u>X</u>.
These prefixes can take values from 0 to 9.
The condition to create a phone prefix is:
- The first digit cannot be 0 or 1
- The middle digit is either 0 or 1.
The possible number of ways to fill the first place is 8 since 0 or 1 cannot be the first digit.
The possible number of ways to fill the second place is 2 since the middle digit can be occupied by either 0 or 1.
The possible number of ways to fill the last place is 10 since there are no condition applied to the last digit.
Then the number of phone prefixes that can be formed is =
Thus, the possible number of phone prefixes possible is 160.
Answer:
74 Cars
Step-by-step explanation:
If each motorbike has 2 wheels then we need to find how many wheels the motorbikes already take up.
We do this by doing 14*2 and we get 28 wheels.
Afterwards, we subtract this from the total of 324 to see how many wheels are left over. 324-28=296
Now we know the remaining amount of wheels and with this we can get our final answer!
Since there are 296 remaining wheels and each car takes up 4 we can divide 296 by 4 to see how many cars would be able to get their full set of tires.
296/4 = 74 and that;s how you get 74 cars!
