Answer:
72 houses.
Step-by-step explanation:
We are told that a postal worker can deliver the mail to 18 houses in 15 minutes.
Let us find numbers of mails delivered by postal worker per minute.
Since we know that 1 hour equals 60 minutes, so we will multiply 1.2 by 60 to find the number mails postal worker will deliver in 1 hour.
Therefore, the postal worker will be able to deliver mails to 72 houses in 1 hour.
If the length of side of base is 14 inches and height is 6 inches of pyramid a then the volume of pyramid a is 12.5% of pyramid b and volume of pyramid a is 8 times bigger than volume of pyramid b.
Given the length of side of base of pyramid a is 14 inches , height of pyramid a is 6 inches and volume of pyramid b is 3136 cubic inches.
We have to determine the percentage and number of times that volume of b is bigger than volume of pyramid b.
Volume of a square pyramid=base area * height/3
Base area = Side * side
=14*14
=196 inches square.
Volume of pyramid a =196*6/3
=392 cubic inches.
Percentage=Volume of pyramid a / volume of pyramid b*100
=392/3136*100
=12.5%
Let the number of times be x.
So,
392*x=3136
x=3136/392
=8 times.
Hence the volume of pyramid b is 8 times bigger than volume of pyramid a and the percentage is 12.5%.
