Answer: There are 8 edges and 5 verticles
Step-by-step explanation:
This is a square pyramid. The base is 1 face. The sides that are touching the base and touching at the point that the top is 4 faces altogether. 4+1=5 faces. You can also count the number of faces. (1 face is a square (the base) and the other 4 faces are the sides).
Ok vertices are the points. There are 5 points. Points are where edges touch. (4 vertices are touching the square, the last vertice is at the top of the pyramind)
There are 8 edges. Edges are the literal "edges". You can count. The square on the bottom has 4 edges. The edges touching the top point there are 4 edges. There are 8 edges in total. (4 edges are sides of the square, the other edges are pointing to the top of the pyramind)
The first choice is wrong because it does not have 5 faces.
The second one is correct, the figure has 5 vertices and 8 edges.
The third one is wrong because the figure doesn't have 8 vertices
The last one is wrong it does not have 4 faces.

Step-by-step explanation:
Given
Represent the weight of the Jar with J and the sugar with S
Initially, we have:
After 2/3 of sugar is removed we have:
Required
Determine the weight of the jar
--- (1)
--- (2)
Simplify (2)
Take LCM
Make S the subject in (1)
Substitute 850g - J for S in
Multiply through by 3
Collect Like Terms
Make J the subject
<em>The jar weighs 370g</em>
Answer:
i cant see the photo its messy or is it just me
Step-by-step explanation:
The formula to use is
A=p(1+(r/n))^(nt)
P= principle
R= rate
N= number of times it's compounded per year
T= time in years
Quadruple means 4 times
24000=6000(1+.035)^t
Divide by 6000
4= (1.035)^t
To bring the variable out of the power you take the log of both sides.
Log4= t Log1.035
Divide both sides by log1.035
(Log4)/(log1.035)=t
40.30=t
