Answer:
11,232,000 different plates
Step-by-step explanation:
Figure it out like this:
2letters × 3digits × 1letter
Nothing can repeat. There are 26 letters in the alphabet. If we use 1 of those letters, then there are only 25 letters left to choose from. That's why we start with 26 × 25.
Now for the digits, we have 10 choices for the first digit, then 9 choices for the second digit, then 8 choices for the third digit. That's why we follow the letters with 10 × 9 × 8.
For the last letter, we had 24 choices left, so the whole thing is found by multiplying:
26 × 25 × 24 × 10 × 9 × 8 × 24 = 11,232,000
There are 45 minutes in 3/4 of an hour.
3.78
All you need to do is plug in the numbers to your calculater, but since I'm guessing your in grade school, and they don't allow calculaters yet, you would need to understand that when two negatives multiply each other, they become positive, so you can just put
0.6
x 6.3
---------
and then just multiply as usual (ignore the decimals for now)
and then you would get 378.
Now, what you would do is because there is too decimal points in the two numbers you are multiplying, you put them into 378, making it 3.78.]
I'm sorry if it was confusing, I hope it helped!
