Q1. A business jet burns 300 gallons of gasoline per hour. How many gallons of gasoline will the jet burn in a three hour flight?

Let the number of gallons required in 3 hours be = x

$\frac{x}{3}=\frac{300}{1}$

x=900 gallons.

The business jet burns 900 gallons of gasoline in a three hour flight.

Q2. On average, one gallon of gasoline weights approximately six pounds. How many pounds does fifty gallons of gasoline weigh?

Let the weight in pounds of 50 gallons be = x

$\frac{1}{6}=\frac{50}{x}$

x=300 pounds

Fifty gallons of gasoline weighs 300 pounds.

Q3. For every one yard, there are thirty-six inches. Convert 2,124 inches to an equivalent number of yards.

Let the number of yards be = x

$\frac{1}{36}=\frac{x}{2124}$

36x=2124

$x=\frac{2124}{36}=59$ yards

2,124 inches = 59 yards

Q4. A person who weighs 240 pounds burns 180 calories per mile of running. If a person burns thirty-six calories by running one mile, how much does the person weigh?

Let the weight of the person be = x

$\frac{240}{180}=\frac{x}{36}$

$180x=240\times36$

180x=8640

x=48 pounds

A person who weighs 48 pounds, burns thirty-six calories while running one mile.

Q5. A rice casserole recipe serves four people and requires two tablespoons of butter. How many people will the rice casserole serve if the recipe is scaled to require six tablespoons of butter?

Let the number of people who can be served be = x

$\frac{4}{2}=\frac{x}{6}$

2x=24

x=12

A rice casserole that requires six tablespoons of butter serves 12 people.

i got a hair cut today from my mom not to flex just to flex kim jon un is one rad fellow i'd say you'd need to take the hairline in kinda like a box shape like someone rammed a lego brick into your head. from there you really need to take the top up keeping with that boxy aesthetic, finally coat the whole thing with gel if your country economics are failing or whatever you can just coat it with the starving children's food rations. about 5 orphans per strand is a good ratio. good luck with the fresh cut my dude
