Answer:
9
Step-by-step explanation:
to make it easier, you can imagine multiplying both by 100 first to get rid of the decimals, so you are just left with 27÷3=9.
<span>The answer is: 2. 11
Crowbar is a Class A lever
Therefore the mechanical advantage of the crowbar can be given by either:
MA = Output distance/Input distance
OR
MA = Output force/Input force
Since, the question gives only the force, we can use the second formula.
MA = Output force/ Input Force
= 330 N / 30 N
= 11</span>
The answer is 2/9 in lowest terms.
In decimal form its 0.222222
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.
