question 15 (5 points)
a farmer wants to know how many bags of fertilizer to buy to ensure that his entire field will be covered. he estimates his field to be 900 feet by 500 feet. a more accurate measurement of the field results in the field being 910 feet by 520 feet. one bag of fertilizer covers 5000 square feet of the field. the farmer uses his estimated numbers to figure out how many bags of fertilizer to buy.
(900 ft)(500 ft) = 450000 ft²
the farmer needs to cover 450000 ft², since each bag covers 5000 ft², he divides the total square feet of his field by 5000.
450000 divided by 5000 is 90. the farmer buys 90 bags of fertilizer to cover his field. explain the effects that an error in measurement has on the farmers estimated measurements by comparing them to the more accurate measurements.
there is not enough information given in the question to compare the estimated measurements to the more accurate measurements.
by using the estimated measurements, the farmer will not have enough bags of fertilizer to cover his field. he will need 10 more bags to cover the entire field.
