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...

Hi Luis,
The definition of decasyllabic is a metrical line of 10 syllables with the prefix deca meaning 10. So just count the number of syllables in each response and you will find that one of them is exactly 10 syllables long.
Hope this helps,

Katrina,
In order to be able to help you with the question a bit more info is needed. Info required would be moslty based on environmental factors and what has changed to affect mussel species viability and this populations. If you could provide that information then I'm sure we...

Hi Taryn,
Interesting question. As we know the astronauts who visited the moon took pieces away in the form of rock and soil samples. They now sit in several museums. I guess it really depends on the size of the piece you remove. If a chunk with a mass of thousands of kilotons...

Hi Paula,
First of all, let's look at the info we have.
We know that the auditorium is 16 inches from the town hall as seen on the map.
We know that the map scale shows that 1/2 inch equals I mile.
So we set up the problem this way:
16 inches x 1 mile per...

The equation to find the volume of a cylinder is pi x r2 x height. pi=3.14, r=1/2 diameter (3 ft in this case)
so we plug the number the numbers into the this equation and we get
3.14 x 32 x 14 ft =
3.14 x 9 x 14 ft = 395.84 cubic...

Hi Mercedes,
First let's make sure we identify the standard quantity of our units; we have grams that we need to convert to kilograms. Kilo means the same as 1,000 so there are 1000 grams in one kilogram.
Now, let's see how much all the items in the sandwich weigh:
15...

This theory states that cosmic dust, all the dust in the cosmos or our solar system less than .1 micrometer in size, collided and stuck together accumulating in sufficient size to form a planet.
The astronomical unit, abbreviated AU, a.u., and ua is...

Hi Katrina,
Let's set this up like a regular algebra problem where you solve for x.
We know we have a board that is 64 ins long cut into three pieces. So let's make the first piece the unknown "x". We know that the second piece is three times longer than...
