2^(x+3) = 512
Answer:
The constant of proportionality between the actual dimensions of the pavers and the model is 9.
The proportionality constant for the area is 81.
Step-by-step explanation:
To solve this problem, let's transform all quantities to the same units (inches)
The actual dimensions of the pavers are:
Then we divide the real dimensions between those of the model:
Width:
Long =
Then, the constant of proportionality between the actual dimensions of the pavers and the model is 9.
Actual length = model length * (9)
The "A" area of a paver is the product of its width multiplied by its length.
So:
(real width) * (real length) = ((9) Model width) * ((9) model length)
(real width) * (real length) = * (Model width) * (model length)
(real area) = 81 * (Model area)
The proportionality constant for the area is 81.
Answer:
The length of a paver in the model and the length is 1/9.
The constant of proportionality that relates the area 1/81.
Step-by-step explanation:
Area of rectangle is
Dimensions of paver in model:
Area of model
The area of the model is 1/18 square inches.
We know that 1 ft = 12 inches
Actual dimensions of paver:
Actual area is
The actual area is 4.5 square inches.
The constant of proportionality that relates the length of a paver in the model and the length of an actual paver is
The length of a paver in the model and the length is 1/9.
The constant of proportionality that relates the area of an actual paver is
The constant of proportionality that relates the area 1/81.
The measurements at the cereal box are 30 cm X 40 cm x 5cm
Do you have enough wrapping paper to wrap the cereal box?
Yes, you have enough wrapping paper to wrap the cereal box.
To determine if you have enough wrapping paper to wrap the cereal box, you need to find the surface area of the box and compare it to the area of the square sheet of wrapping paper. The surface area of the cereal box can be found by adding up the areas of all six sides. In this case, the surface area of the box is 2(30 * 40) + 2(30 * 5) + 2(40 * 5) = 2400 + 300 + 400 = 3100 square centimeters. The square sheet of wrapping paper has an area of 60 * 60 = 3600 square centimeters. Since the surface area of the cereal box is less than the area of the wrapping paper, you have enough wrapping paper to wrap the box.
