Name two geographic obstacles and one political obstacle that stood in the way of the construction of the Panama Canal.
Answer: The two geographic obstacles that stood in the way of the construction of the Panama Canal was that Panama was very mountainous, and there were a lot of mud slides. One political obstacle was that Panama was part of Colombia. The united states had to negotiate with Colombia before Panama became independent. Engineers had to build a dam, design and build locks, and remove huge amounts of earth and rock in order to overcome the geographical obstacles.
I hope it helps, Regards.
Answer:
One way forests were revived was from the replanting of many local trees, such as conifers, spruce, etc. This resulted in blooming and mass regrowth of forests. Another way forests were returned to their healthy condition was from redirecting species such as cattle away from the shrubbery, which allowed saplings to grow safely. A third way that people revived forests was by enabling a fire restriction. By keeping fires away from these precious forests, the trees could grow without harm.
Step 1
List all of your options as the row labels on the table, and list the factors that you need to consider as the column headings. For example, if you were buying a new laptop, factors to consider might be cost, dimensions, and hard disk size.
Step 2
Next, work your way down the columns of your table, scoring each option for each of the factors in your decision. Score each option from 0 (poor) to 5 (very good). Note that you do not have to have a different score for each option – if none of them are good for a particular factor in your decision, then all options should score 0.
Step 3
The next step is to work out the relative importance of the factors in your decision. Show these as numbers from, say, 0 to 5, where 0 means that the factor is absolutely unimportant in the final decision, and 5 means that it is very important. (It's perfectly acceptable to have factors with the same importance.)
Tip:
These values may be obvious. If they are not, then use a technique such as Paired Comparison Analysis to estimate them.
Step 4
Now multiply each of your scores from step 2 by the values for relative importance of the factor that you calculated in step 3. This will give you weighted scores for each option/factor combination.
Step 5
Finally, add up these weighted scores for each of your options. The option that scores the highest wins!
Answer:
El niño gastó 
y le quedó 
del ahorro.
Explanation:
Sea 
la cantidad total inicial de su ahorro. A continuación, transformamos cada oración en una expresión matemática:
(i) <em>Un niño gasta </em>
<em> de su ahorro inicial</em>:
(1)
(ii) <em>Luego, gasta </em>
<em> de su ahorro actual</em>:
(2)
Ahora, la porción remanente del ahorro es:
El niño gastó y le quedó del ahorro.
