Answer:
2>x
y>-1
Step-by-step explanation:
assume y=0 when finding x and vice versa
One pie costs 0.10
you are buying 40 pies so...
40 x 0.10 = $4
one cup of coffee costs 0.50
you are buying 20 coffee so...
20 x 0.50 = $10
$4 + $10 = $14
It costs $14 to buy 40 pieces of pie and 20 cups of coffee
Answer:
P = 1 / 6
Step-by-step explanation:
Given:-
- A deck has 500 cards
- Numbered from 1-500
Find:-
you are asked to pick three cards, one at a time, what's the probability of each subsequent card being larger than the previous drawn card
Solution:-
- Suppose we draw three cards. We don't care what they actually are, irrespective of number.
- Let the three numbers be a, b, c: Such that:
a < b < c.
- The total possible combinations with 3 numbered cards will be:
a b c
b a c
a c b
b a c
b c a
c a b
- We have 6 possibilities for 3 numbered cards. So the probability of of each subsequent card being larger than the previous drawn card would be:
P = 1 / possible combinations
P = 1 / 6
17.7 gallons of gas would she require to travel 413 miles at this rate when Jenny used 9 gallons of gas to travel 210 miles.
Given that,
Jenny used 9 gallons of gas to travel 210 miles.
We have to find how many gallons of gas would she require to travel 413 miles at this rate.
We know that,
Jenny used 9 gallons of gas to travel 210 miles.
Then
Rate = 210 miles/9 gallons
= 23.3 miles/gallon.
So,
Nicole can achieve a fuel efficiency of 23.3 miles per gallon.
He has a 413-mile drive ahead of him.
So,
413/23.3 = 17.7 gallons needed.
Therefore, 17.7 gallons of gas would she require to travel 413 miles at this rate when Jenny used 9 gallons of gas to travel 210 miles.
