Remember to use the Please Excuse My Dear Aunt Sally acronym: 5x5+5x5+5-5x5 25+25+5-25 the negative 25 cancels the other 25 so you are left with: 25+5 which equals 30
1 and 2 are correct, as far as I can figure out. You would leave number 1 as 2.5, if not a more complex decimal. As a mathmatician, you will always show the decimals to several points out. Scientists don't like this saying that extra decimals just create
I am not sure what the formula is, but I can tell you that 1/4 multiplied by 80 is not 60. It would be 20. 60 is 3/4 of 80.
Ok thanks!
No. I am supposed to use a quote as my title.
X^2+20 you add the units
Try pluging in x coordinates between -5 and 5 to find your vertex
Do 85 dived by 75 to get your answer in percentage
You cannot simplify this equation unless it is equal to something
(X+8)/6
You can't subtract a (
What is do the numbers around the equation mean? Are they part of it?
So -|-5-7| =-|-12| =(-1)(12) =-12
So first 50000000 times .8 which is the opposite of 20% which gives you your first answer of 40 million left over. The equation for the interest after this is 40000000(0.7^30)
You are correct as far as I see, and the fast food question, you are correct, just usually the menus are a lot different
Mrs sue put the equation for a interest that was put to the initial price and collected annually, this is not what the question is asking for.
8,500$ car, wow So if the interest rate is 4.6% for 5 years, she has to pay that percentage of the total cost each year. There is an equation for this, but to make it simpler ill tell you it this way: 8500 Initial cost 8500*1.046 cost after 1 year =8891
3x-8>5 So 3x>5+8 3x>13 x
The vibration increased and the sound relayed is constant
México, que era precioso. Siguiente Italia parada.
Jack-5=John See if that gets you anywhere, you need to do substitution.

3592736 is wrong. 461592*308=142170336. Then the final answer should be 156118096
Um, those fractions are in their simplest forms.
Yes, as long as the equation is not rationalized.
Plug the equation in in separate parts. Otherwise most calculators would change the steps up. Try this to start (8/(2^3))-2+(4.1*2). Remember the steps in solving an equation (power, parentheses, multiplication, division, addition, subtraction. In that
So 2/5 of the stamps are left with 12 stamps. So there for 1/5 of the stamps is 6 stamps. Now just multiply 6*3 for the amount that he sent. =18
Independent is by itself. Dependent needs a problem before it.
C(x)=70x-1000
Never mind everyone. I graphed it and showed him I was correct.
Um computers transformers and anything with a USB port.
1c 2a 3(you need a percentage to start with) Converting percentage to decimal is easy. First get rid of the percentage sign by crossing it off. Then move the decimal 2 places forward. Here I did an example following these steps below. 27% 27 2.7 0.27 Just
For the first part, it is just asking for a life cycle in math terms. A plant will grow a lot more in its first week than in its second third and so on. It's decay is 2x faster than its growth. For the second part, just ask your fellow students.
Eric, this really depends on if the block is porus. Could you please respond back with more details? I am willing to help. Also, what is the surface tension of the water?
Hmm, does your teacher want a specific decimal place? If so, you just tell the numbers as they calculate out to that decimal place (ie 0.284926493 if asked for ten thousandth place would just be 0.2849).
That is 2808, but let me show you how to easily calculate this out. For an example, 1507*1.93. If you plug this into a calculator you get the answer of 2908.51. Significant figures are just simplified numbers that engineers use. Since there is no machine
304.8 the sig fig does not go down on this problem.
This problem has some missing information. You know that the pole is 16 feet high, and the wires connect 12 feet up (16-4=12). If you found the length from the bottom of the pole to the grounding point, you could use the equation 12^2+X^2=L^2 with x
