What does "What scale would be appropriate to graph the data?" mean?

Answers

I think it means which graph is the best at representing the data or data set.

For example if you were to graph the population of an animal you would use a line graph to represent the data

If you were determining how much percentage you would get a job you would use a pie graph. Etc

Lynette has a metal doorstop with the dimensions shown. Each cubic centimeter of the metal in the doorstop has a mass of about 8.6 grams. Find the volume of the metal in the doorstop. Then find the mass of the doorstop.(Picture is provided)

Answers

Answer:

The answers are:

Volume: 75 cubic centimeters

Mass: 645 grams

Step-by-step explanation:

In order to determine both volume and mass of the doorstop, we have to know the formulas of a triangular prism.

I have attached an image that shows some formulas about triangular prism.

As we see in the image, a triangular prism consists basically in a triangular face and its projection.

So, using the variables and formula of the image:

B=10 cm

H=6 cm

L=2.5 cm

$V=(1)/(2)*B*H*L\nV=(1)/(2)*10*6*2.5\nV=75$

Then, we know the density of the metal that is:

δ= $8.6 (gr)/(cm^3)$

So, the mass of the doorstop is:

m=δ*V

m=8.6 $(gr)/(cm^3)$ * 75 $cm^3$

m=645 gr

Finally, the volume is 75 $cm^3$ and the mass 645 gr

75 is the volume. 510 is the mass.

The energy an object has due to its motion is called ?

Answers

Answer:

The energy an object has is due to it's Kinetic Energy.

Step-by-step explanation:

Final answer:

Kinetic energy is the energy an object possesses due to its motion. It is calculated using the formula K.E. = 0.5 * mass * velocity^2.

Explanation:

The energy an object has due to its motion is called kinetic energy.

Kinetic energy is defined as the energy an object possesses because of its motion. The amount of kinetic energy an object has depends on its mass and its velocity. The formula for calculating kinetic energy is K.E. = 0.5 * mass * velocity^2.

For example, if we have a soccer ball with a mass of 0.5 kg and it is moving at a velocity of 10 m/s, we can calculate its kinetic energy as follows:
