Answer:
187.5 gallons
Step-by-step explanation:
Make a proportion
=
3000/16 = 187.5, so multiply 1 by 187.5 to find the gallons used in a year
This gets you 187.5 gallons used in a year
1875 gallons of gas
He travels 30000 miles per year, and each gallon lets him travel 16 miles. Divide 30000 by 16 to get the amount of gas he uses in a year, which amounts to 1875 gallons of gas.
4,500 mL should/will be the right answer
is the required inequality
Let the number of songs = m.
The cost of downloading 1 songs = $1.29
So, the cost of downloading 'm' songs = dollars
Since, the maximum amount she can spend on downloading songs is $20.
So, we get the inequality,
Hence, the inequality representing the situation is .
We first must calculate how many ways 2 oblects can be chosen from 5.
combinations = 5! / 2! * (5-2)!
combinations = 5*4 / 2
combinations = 10
There are 10 ways to choose the 2 buttons and 5 ways to choose the final butto so there are 10 * 5 = 50 different ways.
