Who wants to help me on question 41. I don't understand what it means when it says "label a net".
2 answers:
A net is basically a flattened out 3D solid. If you fold all the sides up, you would end up with the 3D model.
What it means by net is an image of the 3d shape if you were to unfold it. Imagine what kind of shape you would get if you were to unfold a cardboard box, for example. Then, after you draw that, it wants you to transpose the measurements of the shape onto the net. I've included an image showing the net of a rectangle prism along with the labels the question asked.

Answer: ≈ 8%
Step-by-step explanation:
Total number of students = total number of boys + total number of girls
Total number of students = 88 + 75
Total number of students = 163
10.2% of the boys have blue eyes , this means that 10.2% of 88 have blue eyes
x 88 = 8.976
Since we are dealing with humans , therefore , this means that 9 boys have blue eyes.
Also , 5.3% of the girls have blue eyes means that 5.3% of 75 have blue eyes. That is
x 75 = 3.975 , therefore : 4 girls have blue eyes.
In total , 13 students have blue eyes
Therefore , to calculate the % of students that have blue eyes , we have :
13/163 x 100 = 7.975460123
Therefore : ≈ 8% of the students have blue eyes
