Answer:
1.03
Step-by-step explanation:
To find the volume of a prism, find the area of the base and multiply it by the height.
The base is an octagon. The area is found 
. Substitute a = 0.5.
The volume is 1.21*2.5 = 3.025.
However, there are three holes drilled out half way which each have volume 0.06.
The volume is found as V = πr²h. Substitute r = 0.125 which is half the diameter of 0.25. Since they go half way, the height is h = 1.25.
V = π(0.125)²(1.25) = 0.06.
Since there are 3, they equal 3*0.06 = 0.18.
Subtract this from the volume.
1.21 - 0.18 = 1.03
Answer:
The percentage change of vacationers is 33.3 %
Step-by-step explanation:
Given as :
The old value of the vacationers = $ 1500
The new value of the vacationers = $ 2000
Let the percentage variation = x %
Or, x % increase = 
× 100
Or, x % increase = 
× 100
Or, x % increase = 
× 100
Or, x % increase = 
× 100
Or, x % increase = 
∴ x = 33.3 %
So, The percentage increase change is 33.3 %
Hence The percentage change of vacationers is 33.3 % Answer
Let :
T = Theresa age
H = her brother
We know :
T = H - 14
T + H = 35
Substitute T
H -14 + H = 35
2H - 14 = 35
2H = 49
H = 49/2 = 24.5
Since we know H = 24.5 we then can substitute it to either equation.
T = H - 14
T = 24.5 - 14
T = 10.5
Theresa is 10.5 years old
Her brother is 24.5 years old
