If the volume for 3-D polyhedra A is 200 cm3 and the volume for 3-D polyhedral B is 800 cm3, how many times bigger is the volume of pyramid B than pyramid A?

The volume of pyramid B is 3 times bigger than the volume of pyramid A

Step-by-step explanation:

Proportions

The proportion or ratio between two quantities a and b is the result of the division a/b.

The ratio is greater than 1 if a>b, less than 1 if a<b and exactly 1 if a=b.

We are told the volume for 3-D polyhedra A is 200 and the volume for 3-D polyhedral B is 800 . Computing the ratio:

This means the volume of pyramid B is four times the volume of pyramid A, but that is not the answer to the question. We must say how many times B is bigger than A.

The relation obtained by the computed ratio is B being 4 times A, it means it's 4A - A = 3A

The correct answer is: The volume of pyramid B is 3 times bigger than the volume of pyramid A

answerthe vertex form

step-by-step explanation:

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
