Answer:
time taken=1800 seconds
Step-by-step explanation:
velocity=v=10m/s
distance=S=18km=18×10³m=18000m
t=?
as we know that
velocity=
velocity×time taken=distance covered
now here we have to find time
time taken=
time taken=
time taken=1800seconds
Answer:
(f- g)(x) = x - 3
Step-by-step explanation:
(f- g)(x) = f(x) - g(x)
This means that you have to subtract the two equation.
If f(x) = 3x - 2 and g(x) = 2x + 1
Then
f(x) - g(x) = [3x - 2] - [2x+1]
= 3x - 2- 2x - 1
= x - 3
∴ (f- g)(x) = x - 3
The given rock is a diamond because its density ranges among 3.5 and 3.54 g/cm³.
<h3>What is density?</h3>
Density is the mass of a specific material per unit volume. Density is commonly measured in grams per cubic centimetre. Water, for example, has a density of 1 gram per cubic centimetre, whereas Earth has a density of 5.51 grams per cubic centimetre.
- Density is also measured in kilograms per cubic metre (or metre-kilogram-second or SI units).
- Air has a density of 1.2 kilograms per cubic metre. Textbooks and handbooks list the densities of popular solids, liquids, and gases.
- Density provides an easy way to calculate a body's mass from its volume and vice versa; a mass is proportional to the quantity multiplied by density (M = Vd), or the volume is equal to mass divided by the density. (V = M/d).
The formula for density is;
D = M/V,
where,
D is density,
M is mass ( = 1.17 g)
V is volume (0.33 cm³)
Substituting the values in the density formula;
Density = 1.17/0.33
Density = 3.54 g/cm³
As, diamond has a density that ranges between 3.5 & 3.54 g/cm3. As a result, the above rock is indeed a diamond.

The correct question is-
If a rock sample has a mass of 1.17 g and a volume of 0.33 cm3, what type of rock is it?
Answer:
The average occupancy rate for the past three nights is of 86.49%.
Step-by-step explanation:
We want to find the average occupancy rate, as a percentage.
You've sold 101 rooms, 98 rooms, and 102 rooms over the past 3 days.
So the mean number of rooms sold during the past 3 days is given by:
Average rate:
The average occupancy rate for the past three nights is of 86.49%.
