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.

Answer: 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

Answer: 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

Answer: 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

Answer: 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?

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

2x=24

x=12

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

HELP! PLEASE! Jackson is building a small rectangular basketball section in his backyard. The length of the section will be 1.25
Misha Larkins [42]

Answer:

Part A) A=1.25W^2

Part B) Length: 17.5 feet and Width: 14 feet

Step-by-step explanation:

Part A) Create an equation to represent the area of the basketball section A, in terms of the width W.

Let

L ----> the length of the  rectangular basketball section

W ---> the width of the  rectangular basketball section

we know that

The area of the rectangular basketball section is equal to

A=LW ----> equation A

The length of the section will be 1.25 times the width of the section

so

L=1.25W ----> equation B

substitute equation B in equation A

A=(1.25W)W\\A=1.25W^2

Part B) Jackson decides to make the area of the basketball section 245 square feet. What are the dimensions, in feet, of the basketball section?

we have

A=1.25W^2\\A=245\ ft^2

so

245=1.25W^2

solve for W

W^2=245/1.25\\W^2=196\\W=14\ ft

Find the value of L

substitute the value of W in the equation B

L=1.25(14)=17.5\ ft

therefore

The dimensions are :

Length: 17.5 feet

Width: 14 feet

What is the equation of aline that passes through the point (4,-8) and has a slope of -1/2?
viktelen [127]

Answer:

The equation of the line will be:

y=-\frac{1}{2}x-6

Step-by-step explanation:

Given

  • slope = m = -1/2
  • point (4, -8)

Point slope form:

y-y_1=m\left(x-x_1\right)

substituting the values m = -1/2 and the point (4,-8)

y-\left(-8\right)=\frac{-1}{2}\left(x-4\right)

y+8=\frac{-1}{2}\left(x-4\right)

subtract 8 from both sides

y+8-8=\frac{-1}{2}\left(x-4\right)-8

y=-\frac{1}{2}x-6

Therefore, the equation of the line will be:

y=-\frac{1}{2}x-6
