At a grocery store, apples cost $2 per pound and oranges cost $3.50 per pound. The function representing the total cost, in doll

ars, for x pounds of apples and x pounds of oranges is f(x) = 5.5x. How does the mathematical domain of the function compare to the reasonable domain? The mathematical domain includes all real numbers, while the reasonable domain includes only whole number values. The mathematical domain includes all real numbers, while the reasonable domain includes only rational values greater than or equal to 0. The mathematical domain includes real numbers greater than or equal to 0, while the reasonable domain includes only whole number values. The mathematical domain includes real numbers greater than or equal to 0, while the reasonable domain includes only rational values greater than or equal to 0.

Which ratios are equal to 64 when the scale factor is 8? Select all that apply.
Luden [163]

Answer:

The scaled surface area of a square pyramid to the original surface area.

The scaled area of a triangle to the original area.

Step-by-step explanation:

Suppose that we have a cube with sidelength M.

if we rescale this measure with a scale factor 8, we get 8*M

Now, if previously the area of one side was of order M^2, with the rescaled measure the area will be something like (8*M)^2 = 64*M^2

This means that the ratio of the surfaces/areas will be 64.

(and will be the same for a pyramid, a rectangle, etc)

Then the correct options will be the ones related to surfaces, that are:

The scaled surface area of a square pyramid to the original surface area.

The scaled area of a triangle to the original area.

You plan to build a house that is 1 ½ times as long as it is wide. You want the land around the house to be 20 feet wider than t
IgorLugansk [536]

The total area with land based on the information given is 3x² + 60x.

<h3>How to find the area?</h3>

Let the width = x

Let the length = (1.5 × x) = 1.5x

Area = 1.5x × x = 1.5x²

The area along with land:

Width = x + 20

Length = 3 × x = 3x

The total area with land:

= Length × Width

= 3x(x + 20)

= 3x² + 60x.
