mrs_skeptik [129]

Answer:

Option A - $\frac{0.5}{2.75}=\frac{2}{d}$

Step-by-step explanation:

Given : Aricela is trying to estimate the distance between her house and the park. On a map with a scale of 0.5 in. = 2 miles, the distance between her house and the park is 2.75 in.

To find : Which proportion can Aricela use to determine the distance, d, between her house and the park?

Solution :

The distance between her house and the park is 'd' miles.

A scale of 0.5 in. = 2 miles

The distance between her house and the park is 2.75 in.

i.e. the scale is 2.75 in. = d miles

The proportion form is

$\frac{0.5\ in}{2.75\ in}=\frac{2\ miles}{d\ miles}$

Therefore, proportion can Aricela use to determine is $\frac{0.5}{2.75}=\frac{2}{d}$ .

So, option A is correct.

Harlamova29_29 [7]

Answer: The definition of volume is the amount of space in a certain 3D object.

Step-by-step explanation: For instance, a fish tank has 3 feet in length, 1 foot in width, and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. So the volume of the fish tank is 6 cubic feet.
