Instead of using other's opinion to determine your own, especially when it comes to history, I always recommend to my students they do their own research to determine their own opinion.  It is mistake to judge history based on current opinion.  We study history to learn, not to judge. ...

We have a map with a scale of 1 inch is equal to 40 miles.   The problem tells us that on this map we have two cities that are two and 1/4 inches apart.   So, now that we know that the map scale is 1 inch that is equal to 40 miles and we have two cites that 21/4 miles...

Let's look at it this  way.  If we change the number of  electrons we just change the charge of the element; in other words we get an ion, but it's still the same element only with a different charge.  If we change the number of neutrons we get an isotope and  change the...

While it is true that elevated blood serum levels of certain types of cholesterol, LDLs or  Low Density Lipo Proteins, can lead to clogged arteries, high levels of HDLs, or High Density Lipo Proteins, can actually help to clean up those clogged arteries. We also know some of the properties...

Delvan, there's a couple of answers to this.  If the highway is part of the federal highway system and the parks are part of the federal park system then it will be the federal government.  If the roads and parks are part of the local and municipal systems like state, county and city...

Hussain,   The body compensates for the lower ph caused by increased arterial pCO2 by hyperventilating.  The increase in ventilation causes a drop in arterial pCO2 consequently inhibiting the ventilatory response reestablishing blood ph homeostasis.  This compensation process...

Hi Kim   First of all the order of operations requires we solve what's inside the parenthesis first.  So we distribute the ngeative sign across what's in the parenthesis and we get:   2x-4+x (because of the negative sign iin front of the numbers inside the parenthesis...

Yobani,  You can set up the problem like this:   the variable can be anything you want the unknown number to be; in this case we'll call it "x".   6 times "x" increased by (plus) 17 is (equals) 19   so:   6x +...

Perhaps the best way to interpret saying like this is to define the terms we may not know and them fir them back in to discern a word pattern.   "A golden mind" would be one that is highly valued, rare, and gifted.  Dross refers to something that is of low value or held...

Daniel, This problem can be solved using a technique known as FOIL.  This technique is based on the distributive property of multiplication where every term in the second expression is multiplied by every term in the first expression.  This is how it will work.   First-multiply...

Daniel, This binomial expression can be solved bya process know as FOIL.   First- multiply the first terms of each expression togther; you get 3x(3x) = 9x2   Outside-multiply the outside terms of each expression together 3x(-6) = -18x   Inside-multiply...

Endogamy is defined as marriage within one's own group and exogamy would be marriage outside one's own group.  This group can be defined in any number of ways. An example would be religious endogamy in which a Catholic marries a Catholic.  Exogamy would be where a Catholic would marry...

Hello Sara,   First we need to indentify what the variable is, what we are solving for. We know that Tom has 4 times, plus 2, as many football cards as Max and that all their cards added together equal 72.   So, what we are really looking for is how many cards Max...

Hi Jessie, Accoding to the order of operations we need to do what is inside the parenthesis first, so we need to subtract 3/10 from 3/5. To do this we need an LCD or Least Common Denominator, which in this case is 10.  Now what ever to do to the bottom of the fraction make it ten we...
