The correct mixture of oil to gas in a weed eater is 1/2 pint of oil to 2 1/2 gallons of gas. how many pints of oil are needed for 10 gallons of gas?
Answers
1/2 pint of oil=2 1/2 gallons of gas
X pint of oil= 10 gallons of gas
X= (10*0.5)/2.5
X= 2 pints of oil
Final answer:
To find out how many pints of oil are needed for 10 gallons of gas in a weed eater, we need to set up a proportion using the given ratio. By cross-multiplying and solving for x, we find that 1/4 pint of oil is needed.
Explanation:
To find out how many pints of oil are needed for 10 gallons of gas, we can use the given ratio of 1/2 pint of oil to 2 1/2 gallons of gas. First, we need to change the 2 1/2 gallons of gas to pints by multiplying it by 8 (since 1 gallon is equal to 8 pints). So, 2 1/2 gallons becomes 20 pints of gas. Now, we can set up a proportion using the ratios of oil to gas. The proportion will be (1/2 pint) / (20 pints) = (x pints) / (10 gallons).
To solve for x, we can cross-multiply and then divide: (1/2 pint) * (10 gallons) = (20 pints) * (x pints). Simplifying this gives us x = 1/4 pint of oil. Therefore, 1/4 pint of oil is needed for 10 gallons of gas.

Answer:
Dominique's commute took 9 minutes
Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
Since we are given 3 values with 1 variable, and this is a ratio problem we can use the Rule of Three technique to calculate how long her commute will take. The technique is shown in the picture attached below, but before we can use this technique we need to change the hours into minutes.
1 hour = 60 minutes
Now we can use the technique...
36 miles ⇒ 60 minutes
5.4 miles ⇒ x
Finally, we can see that it to Dominique's commute took 9 minutes.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
5.4/x = 36
x = 5.4/36
x = .15 hour
.15 x 60 = 9 minutes
9 minutes is the answer
