To answer this you will find the volume of the rectangular prism shaped bale of hay and the cylindrical shaped bale of hay. Please see attached picture for the work. When you have these answers divided the volume of the cylindrical shaped bale by the rectangular prism shaped bale to determine how many.
3/5 of 400=x people used it
so we x=400x3/5
x=240
so 240 people used it again.
Answer: 120 students
Explanation:
Let x be the number of scopes
Let a be the number of student at school
1x = 5 students
But 5x = a
1x = 4 students
But the principal needs 6 additional scope so that all the students can use it.
=> (x + 6) = 4 students
=> 4(x + 6) = a
Thus,
5x = 4(x + 6)
5x = 4x + 24
5x - 4x = 24
x = 24
So, there are 24 scopes.
Plug x in both equation and compare:
5x = a
5(24) = a
120 = a
4(x + 6) = a
4(24 + 6) = a
4(30) = a
120 = a
Therefore, the students at the school are 120
Set ? as x, and cross-multiply.
so x^2= 36
x = 6 or x = -6
Step-by-step explanation:
x+50%x=30
150%=30
1.5x=30
x=20
