keeping in mind that perpendicular lines have negative reciprocal slopes, let's check for the slope of the equation above
since we know that's its slope, then
so then we're really looking for the equation of a line whose slope is -2 and passes through (2 , 1)
Answer:
Step-by-step explanation:
Stephen uses kilograms of tofu in each serving of his dish.
He has kilograms of tofu.
We want to determine how many servings Stephen can make.
To do this, we divide the total weight of tofu by the weight per serving.
Stephen can make .
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
(P1*V1)=(P2*V2)
P1= 5 atm
P2= 3 atm
V1= 4L
V2=?
(5*4)=(3*V2)
20=3(V2)
V2=20/3 L which is 6.66666667L
The answer is 50. 50+80= 130. 180-130= 50.
