Each face of a cube has an area of 16 inches squared what is the volume of the cube
lakkis [162]

Answer:

64 in³

Step-by-step explanation:

The volume (V) of a cube is calculated as

V = s³ ( where s is the length of the side )

Given

area = 16, then

s² = 16 ( take the square root of both sides )

s = \sqrt{16} = 4 , thus

V = 4³ = 4 × 4 × 4 = 16 × 4 = 64 in³

Which of the following graphs represent the equation y=3x+2
seropon [69]

Answer:You haven't attached a picture but this is what your line should look like

Step-by-step explanation:

For this equation you simply have to graph it.

First, you have to remember that these equations follow a formula: y=mx+b. m is the slope of you line and b is the y-intercept.

Next, you need to graph it. First, graph your b, in this case 2. You would go up 2 on you graph (graph (0,2)). Then, you would graph your slope which is 3.

Now, remember that slope equals y/x, so think of the number 3 being like 3/1. You would start at (0,2) and go up 3 points in the graph, then over 1 point (graph where you end up). You repeat that from each new point you make until you have enough points to create a straight line.

Hope this helps a bit,

Why do drinks get hot but food get cold?
Kobotan [32]

Answer:

First of all: Heat energy is transferred from higher to lower level.

Normally,a room temperature is about 25°C–27°C. Hot food has temperature higher than that, and (cold) drinks have temperature lower than that. So, heat is transferred from/to the atmosphere to maintain heat levels at the Normal temperature and pressure.

When kept in open, heat transfers from the food (higher level of heat) to atmosphere (lower level), decreasing it's temperature, i.e., making it cold.

Likewise, in case of (cold) drinks, heat is transferred to the drink (lower level of heat) from the atmosphere (higher level), hence making it warmer.
