If you're moving up, you have to add seven. y=lxl+7
The answer is 30
we expect that in every 50 people, 1 will have free admission.
so:
Answer: 61 children attended the musical last night.
Step-by-step explanation:
Let x represent the number of children that attended the musical last night.
Let y represent the number of adults that attended the musical last night.
The musical charges $3.50 for children's tickets and $5.00 for adults tickets. If the tickets sales totaled $823.50. It means that
3.5x + 5y = 823.5- - - - - - - - - - 1
Last night, twice as many adults attended the musical than children. It means that
y = 2x
Substituting y = 2x into equation 1, it becomes
3.5x + 5 × 2x = 823.5
3.5x + 10x = 823.5
13.5x = 823.5
x = 823.5/13.5
x = 61
y = 2x = 2 × 61
y = 122
Answer: 225m^3
Step-by-step explanation:
Volume = Bh where "B" is the area of the base and "h" is the height
So, area of the base = 1/2(length)(height) = 1/2(5)(9) = 22.5 m^2.
Then multiply by the height.
22.5x10= 225m^3
