Answer:
40
Step-by-step explanation:
To find how much gasoline is needed for 480 kilometers, we will need to find how much is needed per kilometers:
13 liters is used for 156 kilometers
156/13 = 12 so 1 liter gasoline is spent per 12 kilometers
So for 480 kilometers we would need 40 liter gasoline because
480/12 = 40
Answer:
<h2>36.14 pounds of 34% copper alloy and 9.86 pounds of 48% copper alloy</h2>
Step-by-step explanation:
First alloy contains 34% copper and the second alloy contains 48% alloy.
We wish to make 46 pounds of a third alloy containing 37% copper.
Let the weight of first alloy used be in pounds and the weight of second alloy used be in pounds.
Total weight =
Total weight of copper =
Subtracting 34 times first equation from second equation,
∴ 36.14 pounds of first alloy and 9.86 pounds of second alloy were used.
