Givens
- The base area is 80 square centimeters.
- The height of the pyramid is 7.5 centimeters.
- The density of the pyramid is 1.7 grams per cubic centimeters.
First, we find the volume of the figure.
Where 
and 
.
Replacing values, we have
The density is defined as
Where we need to find the mass 
, we already know that 
and 
. Replacing these values, and solving for
Then, we use the weight definition, which is
Where 
and 
. Replacing these values, we have
Therefore, the weight of Keenan's paperweight is 3.33 N.
Answer:
x=200
Step-by-step explanation:
let 'x' represent the total number of students
0.40x of the students voted for Gerardo
0.35x of the students voted for Leandro
0.25x of the students voted for Juju
70 students voted for Leandro:
0.35x = 70
by solving we find:
x = 200 students
Lets pick a random number, like 50. Lets decrease and increase it by 50%. After the decrease, you will get 25, but when you increase it by 50%, it's only 37.5. No, because when you decrease it, you have a smaller base, so it increases less than it decreases. 50% of 100 is 50, but 50% of 50 is 25. You can see there is a significant difference.
