Answer:
a function is when the x values dont repeat
Explanation:
Answer:
d =
m
V
m = d×V
V =

d
DENSITY
Density is defined as mass per unit volume.
d =
m
V
Example:
A brick of salt measuring 10.0 cm x 10.0 cm x 2.00 cm has a mass of 433 g. What is its density?
Step 1: Calculate the volume
V = lwh = 10.0 cm × 10.0 cm × 2.00 cm = 200 cm³
Step 2: Calculate the density
d =
m

MASS
d =

V
We can rearrange this to get the expression for the mass.
m = d×V
Example:
If 500 mL of a liquid has a density of 1.11 g/mL, what is its mass?
m = d×V = 500 mL ×
1.11

VOLUME
d =

We can rearrange this to get the expression for the volume.
V =
m
d
Example:
What is the volume of a bar of gold that has a mass of 14.83 kg. The density of gold is 19.32 g/cm³.
Step 1: Convert kilograms to grams.
14.83 kg ×

<span>The temperature of
water 20 minutes after heating depends on its elevation and quantity of water
being boiled. The temperature of boiling water is lower at high elevation and
the more water you put on the kettle, the longer it boils. Approximately, 20
minutes after heating water, the temperature already reached 120 degree Celsius
for it takes 35 minutes to achieve the boiling point of water, which is 100
degrees Celsius.</span>
