1. The vowels of the 26 letters of the English alphabet, excluding y, are 5: a, e, i, o and u.
2. The prime numbers less than 10 are 4: 2, 3, 5 and 7.
3. The raffle tickets have one of {a, e, i, o,u} as the first character, and
one of {2, 3, 5, 7} as the second character.
4. Some examples of the raffle tickets: a2, a3, e5, i7 ...
In total there are 5*4=20 possible tickets, as any of the 5 vowels can be combined with any of the 4 primes.
that is, we have a2, a3, a5, a7, e2, e3, ....u7
5.
The only vowel contained in the word "event" is e.
"the digit is the number of letters in the word event":
the word "event" has 5 letters.
-------------------------------------------------------------------------------------------------- Remark: it is not particularly clear whether it is "the number of letters" or "the number of different letters", in which case there would be 4.
For example, if Adam is asked how many letters are there in his name, we expect him to say "4", unless specifically asked "how many different letters are there" --------------------------------------------------------------------------------------------------
The ticket which matches the description can only be e5
6.
P(e5)=(number of ways e5 may occur)/(total number of tickets)= 1/20=0.05
Zoe can not make enough using 3/4 of a cup if she did she would only have enough for 11 people I suggest using a 1/2 a cup then you will have enough for 17 people so that will be enough for 13 people
First you need to determine the area of the vegetable garden. The vegetable garden is a rectangle with the following dimensions:
L = 24 ft
W = 9 ft
The Formula for the area of a rectangle is:
So let's solve it:
With that, we can figure out how many bags of fertilizer would be needed by dividing the area of the vegetable garden by how much one bag of fertilizer covers:
