Suppose you have a bucket of sand containing 5.5 billion grains of sand ( 5.5×109 grains). most of the grains of sand are white, but there are some brown grains mixed evenly throughout. if the concentration of brown sand is 2.0% , how many grains of brown sand are in the bucket?

Grains of brown sand are in the bucket are .

Step-by-step explanation:

Total number sand grains in the bucket =

Concentration of brown sand grains = 2.0%

Number of brown brain in the bucket be x

Grains of brown sand are in the bucket are .

  1.1×10^8

Step-by-step explanation:

2% of 5.5 billion is ...

  2×10^-2 × 5.5×10^9 = 11×10^7 = 1.1×10^8

About 1.1×10^8 grains of brown sand are in the bucket.
