each cow has 4 legs and each chicken has 2 legs. If a boy counts 42 heads and 144 feet, how many cows are there?

netineya [11]

Solution:

we are given that

Each cow has 4 legs and each chicken has 2 legs.

A boy counts 42 heads and 144 feet.

we have been asked to find how many cows are there?

Let there are x cows and y chicken.

Then we can write

$x+y=42....(i)\\ \\ \text{Sum of Heads}\\ \\ 4x+2y=144\\ \\\\\text{Sum of feet }\\ \\ \Rightarrow 2x+y=72....(ii)\\ \\ \text{Now solve these two equation together we get}\\ \\\\2x+(42-x)=72\\ \\ 2x+42-x=72\\ \\ x=72-42=30\\$

Hence Number of cows=30

marta [7]

Answer:

144 pyramids

Step-by-step explanation:

The volume of a pyramid = 1/3*base area * height

Given: Base area = 3 sq.inches

Height = 4 inches

Volume of each pyramid = 1/3*3*4

= 4 cube inches.

To find the number pyramids can the artist make from block of alabaster artist, we need to divide 576 by 4.

= 576/4

= 144

Therefore, the artist can make 144 pyramids.

Thank you.
