Sally is having a party and she has invited nine of her friends.
Alexeev081 [22]

Answer:

1) 5 limes, 5 lemons, 1,000 mL of pineapple juice, 2,000 mL of lemonade, 1,000 of orange juice

2) Limes = $2, Lemons = $2.5, Lemonade = $1.60, Orange Juice = 80c, Pineapple Juice = 90c

Step-by-step explanation:

1/2 limes · 10 = 5

1/2 lemons · 10 = 5

100 mL of pineapple juice · 10 = 1,000 mL

200 mL of lemonade · 10 = 2,000 mL

100 mL of orange juice · 10 = 1,000 mL

Cost:

5 limes · 0.4 = $2

5 lemons · 0.5 = $2.5

mL to L

1,000 mL of pineapple juice = 1 L, this costs 90¢

2,000 mL of lemonade = 2 L, this costs $1.60

1,000 mL of orange juice = 1 L, this costs 80¢

Overall:

5 limes for $2

5 lemons for $2.5

1 L of of pineapple juice for 90¢

2 L of lemonade for $1.60

1 L of orange juice for 80¢

Please help 40 Points!!!!!
Ann [662]

Answer:

0

Step-by-step explanation:

\lim_{n \to \infty} (\frac{3n^3}{15n^4+5} )=0

Look at the exponent in the denominator and the numerator.

The denominator has a power of 4, while the numerator only has a power of 3. Therefore the denominator will always be growing faster than the numerator, so at one point it'll be equal to zero. For example.

1/10 = .1

1/100 = .01

1/1000 = .001

1/100000 = .0001

....

1/100000000000000000000000000000000000000 ≈ 0

at this point we can just round that number to zero. As you can see, if the denominator is increasing infinitely faster than the numerator than you can just round the answer to 0
