Answer:
The correct answer is 65 students.
Explanation:
Step 1: First we must identify the components of the problem to build our equation.
N: number of students
L: Quantity of magnesium tape available
S: Length of tape required by each student
Our equation for determining the number of students who can obtain correct measurements of magnesium tape is:
N=
Step 2: As S=8,5 cm and L=560 cm
Calculation N:
N=
N=65,88
In rounding we are left with N=65, so we say that for 560 cm of magnesium tape, only 65 students will be able to obtain a correct measure to work with.
Have a nice day!
