Answer:
120 cc yards of water
Step-by-step explanation:
A farmer has 1,000-acre farm. And she irrigates her fields with 120,000 cubic yards of water. We are asked to find how many cubic feet of water does she apply per acre?
1000 acre is irrigated by = 120000 cc yard of water
Hence 1 Acre is irrigated by
cc yards of water
Hence 1 Acre is irrigated by 120 cc yards of water .
Answer:
she use 750 mL of 0.22% solution and 250 mL of 0.1%
Step-by-step explanation:
given data
salt water solution 1 = 0.1%
salt water solution 2 = 0.22%
1 liter of solution contains salt = 0.13%
solution
we will consider here quantity in liters of the 0.22% solution is = x
so that the quantity of 0.01% solution will be = 1 - x
so amount of salt in the mix will be as here
0.22 % (x) + 0.1 ( 1-x) = 0.13% (1)
solve it we get
x = 0.25
and
1-x will be = ( 1 - 0.25 ) = 0.75
so she use 750 mL of 0.22% solution and 250 mL of 0.1%
