Answer:
Step-by-step explanation:
The net of the triangular pyramid is attached below.
Since each of the faces is an equilateral triangle of side 6cm, the base of the pyramid will also be an equilateral triangle of side lengths 6cm .
In the equilateral triangles
Therefore, the surface area of the pyramid formed from the net shown
= 4 X Area of One Triangular Face
I believe the answer is C
Answer:
Step-by-step explanation:
"A graph of paired points that form a proportional relationship" means that the x- and y- coordinates of each (paired) point are proportional; i.e. y = mx.
That represents a straight line graph that passes through the origin (0,0) with slope = m. So the answer is " A straight line can be drawn through all the points and the line passes through the origin."
