Answer:

Area of the rectangle = 144 square inches

Step-by-step explanation:

Area of a rectangle = length × width

Width = 4 inches

Length = 3 feet

1 feet = 12 inches

3 feet = 36 inches

Area of a rectangle = length × width

= 36 inches × 4 inches

= 144 square inches

Therefore,

Area of the rectangle = 144 square inches

A plane can fly 1440 miles in the same time as it takes a car to go 400 miles. If the car travels 130 mph
patriot [66]

Answer:

The speed will be "144 mph".

Step-by-step explanation:

Let the speed of the plane be "x mph".

then,

The car's speed be "x-130 mph".

According to the question,

⇒ \frac{1440}{x} =\frac{400}{x-130}

By applying cross-multiplication, we get

⇒    1440(x-130)=400x

⇒ 1440x-187200=400x

⇒    1440x-140x=187200

⇒                1300x=187200

⇒                       x=\frac{187200}{1300}

⇒                          =144 \ mph

The number of cookies packs needed if the treasurer buys 1 package of brownies bites is 5 packs

<h3>Equation</h3>

  • Total attendance = 75 people
  • Cookies in each pack = 12
  • Brownies in each pack = 15
  • Number of cookies pack = c
  • Number of brownies pack = b

15b + 12c = 75

If 1 package of brownies is bought

15b + 12c = 75

15(1) + 12c = 75

15 + 12c = 75

12c = 75 - 15

12c = 60

c = 60/12

c = 5 packs

  • It is a reasonable value in this context

If 9 packages of brownies are bought

15b + 12c = 75

15(9) + 12c = 75

135 + 12c = 75

12c = 75 - 135

12c = -60

c = -60/12

c = -5 packs

  • The value is not reasonable in this context
