There are approximately 1.2 x 10^8 households in the U. S. If the average household uses 400 gallons of water each day, what is the total number of gallons of water used by households in the U. S each day?

  4.8×10^10 gallons

Step-by-step explanation:

The desired number is the product of the number of households and the volume of water used by each:

  (1.2×10^8 households)(4×10^2 gal/day/household) = (1.2·4 × 10^(8+2)) gal/day

  = 4.8×10^10 gal/day

well we know there are 4 clubs in 52 cards so it’s replaced so it should be 3/51

step-by-step explanation:

6e14 is the answer.
