A local dairy farmer collects 490 gallons of milk from his cows. He keeps 1/35 of the milk for his own use, and sells the rest.

RideAnS [48]

Answer:

666.4 dollars per day

Step-by-step explanation:

Total milk farmer has is 490 gallons

He keeps 1/35 of 490 gallons

so he keeps = 1/35*490= 14 gallons

He sells remaining milk.

Remaining milk = 490-14 = 476 gallons

1 gallon = 4 quart (conversion formula)

so 476 gallon = 4 * 476 = 1904 quart

selling price of 1 quart = 35 cents = 0.35 dollars

so selling price of 1904 quart = 0.35*1904 = 666.4 dollars

So he makes 666.4 dollars per day.

To convert a number from scientific notation to standard form, consider 1.5625 x 10^4. First, focus on the exponential number, which is 10^4. Multiply the base number, which is 10, by itself the number of times indicated by the exponent, which is four. You would do that like this:

10 x 10 x 10 x 10 = 10, 000

Plug the product -- which is 10,000 -- into the original equation to get this:

1.5625 x 10,000 = 15, 625

Therefore, the standard form of this number is 15,625.

For a number in expanded form, convert the number, using basic addition. For example, consider the expanded number 10,000 + 2000 + 100 + 10 + 9. Add up these numbers to get the standard form. Your equation would look like this:

10,000 + 2,000 + 100 + 10 + 9 = 12,119

Therefore, the standard form of the number is 12,119.
