Two triangular pyramids are similar. the volume of the larger pyramid is 729 cm3 , and the volume of the smaller pyramid is 64 cm3. if the perimeter of the base of the smaller pyramid is 8 cm, what is the perimeter of the base of the larger pyramid?

The perimeter of the base of the larger pyramid is 18 cm.

Step-by-step explanation:

We have been given, two triangular pyramids are similar.

Volume of larger pyramid = 729 cubic cm

Volume of smaller pyramid = 64 cubic cm

So, the ratio of volume of larger pyramid to volume of smaller pyramid is given by:

=

Thus the ratio of side of larger pyramid to the side of smaller pyramid is given by: 9:4 or

Given is , the perimeter of base of smaller pyramid = 8 cm

The perimeter of base of larger pyramid will be:

=> cm

Hence, the perimeter of the base of the larger pyramid is 18 cm.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
