Enter your answer in the box.

Answer 1

Could it be 120, Because in order to solve that you take 42 divided by 0.35 and then you get 120

Answer 2

Answer: The number of birds he count in all = 120

Explanation:

Let the total number of birds be x.

Given: Imari went on a hike and recorded the number of each type of bird he saw.

From the circle graph the number of sparrows =35 % of x=0.35x

It is given that the number of sparrows= 42

`0.35x=42\\\Rightarrow\ x=(42)/(0.35)\\\Rightarrow\ x=(4200)/(35)\\\Rightarrow\ x=120`

Hence, the number of birds he count in all = 120
