oops, 10.
Hi Jenna. You probably know that the formula for the distance around a circle (called the "circumference") having a radius "R" is 2*(PI)*(R). PI is about 3.14159, rounded down. (And sometimes people just use 3.14 for easier calculation). So, for a circle
You're welcome and thank you for the explanation.
The probability is 1/8. But odds are expressed in a "for versus against" fashion, or in this case, 1:7 because there's one case where it's a C and 7 cases where it's not a C.
To raise 1 gram of water 1 degree Centigrade, it takes approximately 4.184 Joules of energy. In your 20 Litres, you have about 20,000 grams of water. The energy you have available for use in your problem is 5000 kJ or 5,000,000 joules. (5,000,000 joules) /
Ms. Sue - I've skimmed the stuff below and the pattern matches spambot pickup/reposts, and can likely be ignored entirely.
A Joule is a measure of energy. A Watt is a measure of energy per time. More specifically, a Watt = 1 Joule per second. So, your 100 Watt bulb uses 100 Joules per second. 60 seconds per minute. So, each minute, your bulb transforms 6000 Joules of
While there may be more than one interpretation of what "the same rate" means, under the most reasonable interpretation I get the same answer you got (5/8). Which leads me to ask, why do you say that you "know this is not correct"? Do you have an answer
This is one you can just think through verbally - for each 10 feet of run (horizontal), the rise (height) of the roof changes by 7 feet. Over 30 feet, which can be thought of as "3 runs of 10", the rise (height) will change by "3 rises of 7", or 21. Or,
Well, assume worst-case I guess with glacial. What's that, molarity about 17.4? About 5 pounds of bicarb will do it (2193 grams) then, right?
arti was directing the answer at a prior question by "science cbse school". (Took me quite a while to figure out what was intended as well!)
Why or why not is this case the same as other prepositional phrases where the object of the preposition is expressed as a plural item? For example, "The bag of apples was given to someone who did not need it" is correct. It is the "bag" which forms the
Jai's answer is the correct one for what I think your problem actually was. X = 2 and Y = (-1). When you wrote out the question originally, you or your Grandma didn't complete the first equation (should have been 5x + 4y = 6 (forgot the " = 6" part)) which
I don't really agree with "Writeacher" (cool name, though). The pronoun "it" refers back to "use", which is singular, and therefore "it" (singular) is appropriate in this case. More completely, "it" refers to "use of resources". Antecedent for "that do not
Hi again Julia, is there any chance the problem actually states, "a 7 digit EVEN number no repetition"? If so, then only your first choice is correct.
Well, I'd say check them, but all 4 of the ones I listed look like they work to me, based on the criteria you set out.
It's considered to be neither. Composites can be written as the multiplication of at least two other factors, where the two factors are not that number. For example, 2*3 = 6 means 6 is composite because you can write it out as a product of two other
What you posted as the answer is only 6 digits. Try 9,405,271 which seems to meet all the required criteria. These others all seem to fit the requirements: 9,805,472 (this may be what you intended to write) 8,405,261 9,405,271 Is that about all?
Right - the answer is false. The idea of a set of numbers being closed under an operation (like subtraction, addition, etc.) is that you can apply the operation to members of that set of numbers and only get more members from that set. So, if you try it
Think of it in terms of how far you've gone already at 33 mph, how far left to go right now (and at the speed you will need to solve for, call it "X"), versus on the other side of the equation your original plan in terms of how far you were going to go and
