Question

Rachel loves gardening. This summer, her 10 ft x 10 ft garden space is divided equally among tomatoes, lettuce, and strawberries. a) The instructions for tomato fertilizer suggest applying 1500 lb/ac. How many kilograms of fertilizer should she apply to her tomatoes? How DoWe Ce Convert

Answer 1

Answer:

Rachel needs 0.52 kg of fertilizer.

Explanation:

Since the surface is a square of 10 ft of size its area is A = 10 ft x 10 ft = 1.0 x 10² ft². One third of that space is devoted to tomatoes ("space is divided equally among tomatoes, lettuce, and strawberries"), that is, 1/3 x 100 ft² = 33 ft².

We calculate the kilograms of fertilizer required we need to know 2 equivalences:

1 ac = 43,560 ft²

1 lb = 0.4535 kg

Then, we can use proportions to find out the amount of fertilizer used:

$33ft^{2} \frac{1ac}{43,560ft^{2} } .\frac{1,500lb}{1ac} .\frac{0.4535kg}{1lb} =0.52kg$
