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)
Answer:
3805kg
Step-by-step explanation:
2400 ≥ 2350
1460 ≥ 1455
2400 + 1460≥ 2350 + 1455 = 3805
The lower bound is 3805kg
Answer:
1,2, and 4.
Step-by-step explanation:
Hi there! I know that i am kind of late, but the answer on Edge 2020 are options 1,2, and 4. I hope this helps, have a great rest of your day :D
Option A:
are irrational numbers.
Solution:
Given numbers:
![$\sqrt{17} , 0, \sqrt[3]{8} , \frac{22}{7} , \sqrt{81} , \sqrt[3]{14}](https://tex.z-dn.net/?f=%24%5Csqrt%7B17%7D%20%2C%200%2C%20%5Csqrt%5B3%5D%7B8%7D%20%2C%20%5Cfrac%7B22%7D%7B7%7D%20%2C%20%5Csqrt%7B81%7D%20%2C%20%5Csqrt%5B3%5D%7B14%7D)
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) ![\sqrt[3]{8} =\sqrt[3]{2^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%20%3D%5Csqrt%5B3%5D%7B2%5E3%7D)
Cube and cube roots are get canceled.
![\sqrt[3]{8} =2](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B8%7D%20%3D2)
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) ![\sqrt[3]{14}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B14%7D)
14 cannot be written as
form.
So, it is a irrational number.
Therefore
are irrational numbers.
Option A is the correct answer.
