Pyramid A is a square pyramid with a base side length of 9 inches and a height of 4 inches. Pyramid B has a volume of 8,100 in. How many times bigger
volume of pyramid B than pyramid A?
15
32
54
75

Option d. 75 times.

Step-by-step explanation:

Side length of a square pyramid of Pyramid A = 9 inches

height of pyramid A = 4 inches

where,

a = sides, h = height

= 27 × 4

= 108 inches³

and the volume of pyramid B = 8100

Now we will divide volume of pyramid B by the volume of pyramid A

= 75

Therefore, the volume of pyramid B is 75 times bigger than pyramid A.

Option d is the answer.

1/5x+9 2/5y+7

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.
