Answer: Second option.
Step-by-step explanation:
You need to use the following formula:
Where "B" is the area of its base and "h" is the height.
According to the data given in the exercise, you know that:
Therefore, knowing this values, you can substitute them into the formula shown before and then evaluate, in order to calculate the volume of thi right pyramid whose base is a regular hexagon.
Then, you get:

Question 1:
For this case, the first thing we must do is define variables.
We have then:
x: number of nickels
y: number of dimes
We write the system of equations that adapts to the problem.
We have then:
0.05x + 0.10y = 6.10
x + y = 67
Solving the system we have:
x = 12
y = 55
Answer:
there are 12 nickels
Question 2:
For this case, the first thing we must do is define variables.
We have then:
x: Allan's score
y: Dave's score
We write the system of equations that adapts to the problem.
We have then:
x + y = 375
x = 2y-60
Solving the system we have:
x = 230
y = 145
Answer:
Dave: 145 Allan: 230
Step-by-step explanation:
8, 12(3-x)=48
36-12x=48
-12x=48-36
-12x=12 both side divideos by -12
-12x/-12=12/-12
x= 1
9, x/7=4.5 cris cross
x=31.5
10,5(x-3)=45
5x-15=45
5x=45+15
5x=60 both side divided by 5
5x/5=60/5
x=12
11,-3(x-3)=45
-3x+3=45
-3x=45-3
-3x=42 both side divided by -3
-3x/-3=42/-3
x=14
12,14y-8=13
14y=13+8
14y=21 both side divided by 14
14y/14=21/14
y=1.5
13,3m=5m-8/5
3m-5m=-8/5
-2m=-8/5 cris cross
-10m=-8 both side divided by -10
-10m/-10=-8/-10
x=0.8
