Start with the relation beween cm and dm. 1 dm = 10 cm Now figure out the relationship between CUBIC dm and CUBIC cm. 1 cubic dm = 1 dm * 1 dm * 1 dm 1 dm * 1 dm * 1 dm = 10cm * 10cm * 10cm so 1 cubic dm = 1000 cubic cm See if you can take it from there.
It might be just a portion of the water cycle - evaporation - since it only mentions water going up.
Angie, yes, summer and winter are "reversed" in Antarctica. Gabriel, you should post your own question instead of piggy backing on someone else's. And atoms are not the smallest particles: atoms consist of subatomic particles called protons, neutrons, and
Does the second question mean, "B. Which of the following molecules are likely to form hydrogen bonds [with themselves]?" You can get different answers depending on whether or not that added part is implied.
The majority of volcanoes form near plate boundaries. A good example is the so-called "ring of fire" encircling most of the Pacific Ocean. However, the chain of islands of Hawaii are volcanic but are nowhere near a plate boundary. They arose from a mantle
*********************** x^4-2x^2+1=0 I don't think you can factor that unless its (x^2+1)(x^2-1) *********************** If you FOIL that, you will get x^4 - 1, not x^4 - 2x^2 + 1. You can factor by grouping x^4 - 2x^2 + 1 = 0 x^4 - (x^2 + x^2) + 1 = 0 x^4
1) Solve the first equation for either variable. 2) Every where in the second equation that the solved-for variable appears, replace it with the value it is equal to. 3) You now have only 1 variable in the second equation. Solve the second equation for
Actually, there's a more general way. 1) Is the "state" one of the first 3 elements in the set? Yes {Montana, Washington, Idaho} No {Oregon, Alaska, British Columbia, Alberta}. Suppose the answer is no. 2) Is the "State" one of the first 2 elements in the
You could do the same general thing as Count Iblis suggested but instead of finding the populations, you can use letters in the names of the "States". I will show one possible path (note that the way you phrased the question, you can ask a different set of
solve the first equation for either variable. For example, solve it for x. x + y = -4 x = -y - 4 Then, where ever that variable appears in the second equation, replace it with the value from the first equation that is equal to it. This will allow you to
Karyotypes are pictures of a cell's chromosomes taken when they are the most visible (most condensed). The picture is then edited so that all of the chromosomes are oriented in the same direction, paired up, and then sorted into the correct numerical
Contraction
The only "ticky" part is the negative outside of parentheses. Just convert the negative sign into the implied + -1 and then distribute it. 2 - (x + 4) = x - 3 2 + -1(x + 4) = x - 3 2 - x - 4 = x - 3 You should be able to finish it.
The only "tricky" part is which part you do before the other: the subtraction [5 - 3](1-2x) or the diistribution 5 - [3(1-2x)]. If you remember your order of operations you can figure that out: which has a higher priority, subtraction or multiplication?
But, if you feel you need to show the addition step, then you could do something like this (the vertical addition will probably not line up here) 2.3 + 4.09 = N 2.3 + 4.09 ------ 6.39 6.39 = N
For simple addition of two terms, it is usually fine to just show the result. For example: 2.3 + 4.09 = N 6.39 = N (And if you want, change the sides so that N is on the left)
And if you are allowed to define something by including in the definition what it is not, then for an amphibian I'd define it as amphibian: a non-amniote tetrapod.
FYI: For fish, from the linked-to site, use 2 of the defintions: ********************************* 1. Any of numerous cold-blooded aquatic vertebrates of the superclass Pisces, characteristically having fins, gills, and a streamlined body and including
It is not that there is NO y value, but that there are an INFINITE number of y values.
Remember that "percent" means "per hundred". So 94.6% means 94.6 per hundred, which is the same as 94.6 ----- 100 Either use a calculator or move the decimal point 2 places to the left in the numerator. Either way, you get 0.946. Reading the decimal, we
1) Do you mean what is the square root of 7/10? 2) What process did you use? It look like you just subtracted 4 from the numerator and the denominator and put the four outside.
Have you figured out the pattern?
Nat, use what Count Iblis provided. PS: drwls, the question asks about the momentum of a proton, not a photon.
There is no general method to do this other than pure trial and error. So try different positions for the parentheses until it works.
Another possibility (can't tell exactly what the question is asking) is that a bird, in science terms but not everday terms, is a reptile. The newer classifications attempt to be monophyletic, so the term reptile includes all reptiles and all animals
temperature high It's common sense that evaporation of water occurs at high temperature more readily than at low temperature. humidity low The less water vapor already in the air, the easier it is to introduce water vapor into the air. wind high Wind helps
Remove the parentheses. For the second set of parentheses, consider the - in front of it to be + -1 and distribute the -1 across all terms within that set of parentheses. Rearrange terms so that they are in descending order. Combine like terms.
Because homeruns aren't hit when pigs swim through molasses.
Yes, it is a test cross.
I just figured it out: It's simpler than that. You are declaring all of your numeric variables a LONG. LONG is an integer data type: it does not store anything to the right of a decimal point. Try using DOUBLE (or better, DECIMAL, if your version supports
The problem MIGHT be here. result = ((A(Original)) / ((B(Desired)) / Feet)) Some languages (like C and C++) do integer division unless you explicitly make it do "normal" division. In other words, if you do 5/2 in C the result will be the integer 2, not the
And here are some important experiments that relate to the RNA World (to differing degrees). 1. RNA 20-50 mers were produced using a 10 mer primer on montmorillonite 2. Multiple classes of ribozyme ligases were isolated from a pool of 10^15 **RANDOM** 220
Abiotically (that is, non-biologically) produced organic compounds important for RNA World 1. Purines (xanthine, hypoxanthine, guanine, and adenine) were present in the Murchison meteorite 2. The pyrimidine uracil was present in the Murchison meteorite 3.
Some biochemical evidences that there was once an RNA World... 1. The RNA World solves the chicken-or-egg paradox, “Which came first, DNA or proteins?” The answer would be, neither: an RNA molecule capable of both storing genetic information and
The origin of life (abiogenesis) is not understood anywhere near as well as evolution is, so no one can give you a really strong answer. There are several different theories for the OOL, one of which is the RNA World theory. Originally, it held that a
Your method should work. area = 2 * pi * radius^2 area ~ 6.28 * radius^2 POND: diameter = 20m radius = diameter / 2 radius = 20m / 2 = 10m area = 6.28 * (10m)^2 = 6.28 * 100m^2 area = 628m^2 POND and WALK: remember, the walk goes all the way around the
You've been shown how to solve these types of problems multiple times. It's like someone explains to you how to solve x + 1 = 5, but then you create another post because you don't know how to solve x + 1 = 6, and the another post because you don't know how
In VB, you should use OPTION EXPLICIT whenever possible in order to let the 'compiler' endorce strong typing.
If you cannot learn the GENERAL PROCESS, then you need to be taught the same general thing a million different times. You need to learn how to abstract ideas and then apply them to specific instances.
Is that the exact language used in the original question? What are "two pieces of DNA"? Does it mean the two polynucleotide strands? But they are joined together (into a double helix) all the time, except for short segments at a time that separate during
How did Mendel allow a single garden pea plant to reproduce with itself?
p = mgh Solve that for g using algebra. Since in mgh g is multiplied by m and h, do the opposite: divide mgh by m and h. And remember that what you do to one side of an equation you must do the other side as well.
Draw it out. Draw an equilateral triangle, then place an circle inside of it such that the circle just touches each side. Then draw another circle slightly larger than the first.
The sum of the measures of the three interior angles of a triangle is 180 degrees. So: 2x + 3x - 15 + 7x + 15 = 180 12x = 180 x = 15 So the measures of the angles are 30, 30, and 120. That should be enough for you to answer the question.
Factor out the GCF of the 2 terms. x(x - 5) = 0 Can you take it from there?
If I wanted to be sure to take out a blue block, I would put in only blue blocks.
What exactly is Lucky Coin? What is the probability of winning given a single shot?
Choose a speed for which relativistic effects are negligible. Say, 0.001 c, which is 300 km/s. Solve the classical (p = mv) and the relativistic (p = 'gamma' mv)equations for momentum, using the value selected above for velocity. The results should be
Get all of the terms to the left side by adding -3x and -4 to both sides. -x^2 - 3x - 4 = 0 divide through by -1 (divide each term by -1) x^2 + 3x + 4 = 0 factor the trinomial (x + 3)(x + 1) = 0 see if you can take it from there.
Um, how can one determine a relativistically affected length, if no length at all is given in the problem?
