Ethan owns a farm house. His farm house contains cows and buffaloes. The total number of animals in his farm house is 42. Find the number of cows and the number of buffaloes if the
ratio of cows to buffaloes is 5:9.​

TOTAL NO.OF ANIMALS IN FARMHOUSE=42

RATIO OF COW : BUFFALO=5:9

LET THE NO.OF COWS BE 5X AND BUFFALOES BE 9X

5X + 9X =42

14X=42

X = 42/14

X= 3

TOTAL NO.OF COWS = 5 x 3 =15

TOTAL NO.OF BUFFALOES = 9 x 3 = 27

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
