Answer:
There are 12 teachers.
A. the number of teachers in the school
Step-by-step explanation:
We can use ratios to solve the problem
teacher: students
1 : 25
If there are 300 students, we need to multiply by 300/25 = 12
1*12 : 25*12
12 :300
There are 12 teachers
The most important variable is the number of teachers in the school.
The school may or may not be filled to capacity and the classrooms might not be used.
<u>Answer</u>
<em>12 in by 12 in</em>
<u>Explanation</u>
The original length = x
This makes the length of the cube made to be = x - (2×2)
= (x - 4) in
height of the cube = 2 in
Volume of the cube = (x - 4) × (x - 4) × 2 = 128
= (x² - 8x + 16) × 2 = 128
= 2x² - 16x + 32 = 128
= 2x² - 16x + 32- 128=0
= 2x² - 16x - 96 = 0
= x² - 8x - 48 = 0
lets use the factor method to solve the quadrilatic equation above,
x² - 8x - 48 = 0
proctuct = -48
sum = -8
The two factors are; -12 and 8.
(x + 8)(x - 12) = 0
So the value of x are 12 and -8. Since x is a length, it can not be negative.
∴ x = 12 in.
The original dimensions of the sheet are <em>12 in by 12 in</em>.
