Answer:
2063.9 kg
Step-by-step explanation:
Given,
<u>1 kg = 2.2046 pounds</u>
This can also be written as:
<u>1 pound = 1/2.2046 kg</u>
We have to calculate the value of 4550 pounds in kg up to nearest 10th
Thus,
Solving the above equation, we get:
4550 pounds = 2063.8664 kg
Rounding the above result to nearest tenth as:
<u>4550 pounds = 2063.9 kg</u>
This is a way to factoring trinomials (there exist different equivalent methods).
Multiply the trinomial but the term accompanying . This is the second line. Then, you could take the square of the
, ant try to create a factor () () that will correspond to the expression in the second line. That is, we want
In ? we put the corresponding numbers that, if we multiply them we will obtain 42, and if we add them we will obtain 13. This numbers are 6 and 7. Then, we have
The last step is divide by the number that we multipy in the first step.
