Answer:
$51.84
Step-by-step explanation:
The first step is to take the 20% off of the shoes. To do so, find 20% of 60. 0.20 (20% written as a decimal) * 60 = 12. Subtract 12 from 60 because the shoes are 20% OFF. 60 - 12 = 48.
Now, we must determine the price after sales tax. The sales tax is 8%. So, find 8% of 48. 0.08 (8% as a decimal) * 48 = 3.84. Then, add 3.84 to 48 because sales tax is an addition to the price. 48 + 3.84 = 51.84.
Now, add the label to have your final answer. The shoes cost $51.84.
The equation is
y = -(6/7)*x + 9
We just need to evaluate the function in x = 21
This means
y = -6*21/7 +9 = -6*3 +9 = -18 +9 = -9
(x,y) = (21,-9)
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
Answer: 1/20 = 0.05
Answer:
20.7 mL
Step-by-step explanation:
There is 56.6 mL of solution in the bottle. 3.2 mL is used up.
This leaves us with 53.4 mL (56.6 - 3.2). Then, half of this amount is used up.
This leaves us with 26.7 mL (53.4 ÷ 2).
Then, 6 mL of this is poured out. This leaves us with 20.7 mL (26.7 - 6).
