Achemistry teacher has a 560-cm length of magnesium ribbon. for a class experiment, each student requires an 8.5-cm length of the ribbon. how many students may receive the required length?

15 students

65 students

48 students

66 students

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!

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary
