Answer:
The answer is below
Step-by-step explanation:
Different countries have different metric system of measurement, but the metric system of measurement accepted all over the world is the international system of unit (SI unit)
1 quintal = 220.462 lbs and 1 bushel of corn = 56 lbs.
151 q/ha = (151 × 220.462) lbs/ha = 33289.762 lbs/ha
But 1 hectare = 2.471 acre, hence:
33289.762 lbs/ha =
Since 1 bushel of corn = 56 lbs, hence:
= 240.6 bu/ac
For a Margin of Error: +/- 1 bu/ac, the bushels per acre = (239.6 bu/ac, 241.6 bu/ac)
Option A:
are irrational numbers.
Solution:
Given numbers:
To which of these are irrational numbers:
<u>Irrational:</u>
An irrational number cannot be written in the form , where a and b are integers and b is non-zero.
(1) cannot be written as
.
So, it is a irrational.
(2)
Cube and cube roots are get canceled.
2 is an integer. So it is not a irrational number.
(3) is in the form
.
So it is not a irrational number.
(4)
Square and square root are get canceled.
9 is an integer. So it is not a irrational number.
(5)
14 cannot be written as form.
So, it is a irrational number.
Therefore are irrational numbers.
Option A is the correct answer.
