We know that
the lengths of any two sides of a triangle must add up to more than the length of the third side. (Triangle Inequality Theorem)

Part a) Could the third side of the reflective sticker be 6 cm long? Explain your reasoning. If this third side is possible,
we know that
3+4 > 6-------> 7 > 6-----> is ok
3+6 > 4------> 9 > 4-----> is ok
4+6 > 3-----> 10 > 3-----> is ok
see the attached figure

the answer Part a) is
the third side of the triangle can be 6 cm

Part b) Could the third side of the reflective sticker be 1 cm long? Explain your reasoning
3+4 > 1-------> 7 > 1-----> is not ok
it can't be a triangle

the answer Part b) is
the third side of the triangle can't be 1 cm

Degger [83]

Answer:

$\frac{470}{32-n}$

Step-by-step explanation:

We have been given that there were 32 volunteers to donate blood. Unfortunately, n of the volunteers did not meet the health requirements, so they couldn't donate.

So the number of volunteers that donated blood will be 32-n.

We are also told that the rest of the volunteers donated 470 milliliters each.

To find the units of blood donated by each of the volunteers we will divide total units of donated blood by number of volunteers, who donated the blood (32-n).

$\text{Millimeters of blood donated by each volunteer}=\frac{470}{32-n}$
