cot(200)=2.747477 X cot(-70)=-.363970234=-.999999..... I THINK IT SHOULD BE -1, OR YOU HAVE -70 INSTEAD OF 70. CHECK YOUR BOOK!!!!.
7 3/4%=It means for every $100 or ANY 100 things, you might have to pay 7 3/4 more of whatever it is. Say, you go to a store & you buy a bike that costs $100. But the government may charge the store a 7 3/4% tax, which your dad has to pay on top of $100. So, your new bike will actually cost your dad $100 + $7.75 for a total of $107.75. That 7 3/4% is called a "percentage", which comes from Latin for "Per Hundred"
it should be 4x+4=8x im not in algebra but i read something about algebra that just take off the letters than add, sub,...
(ex)
4xy+x
start with making x=1 because there is no number to add.
than take off the letters on 4xy=4
than add 4+1=5
add the letters to the answer 4xy+x=5xy
This is all I know about algebra
can you please post the solution, i don't understand, i tried working it but not getting the same answer
180 miles devided by 15 inches ?
1 mile=5,280 feet
1 foot=12 inches
Therefore: 180 X 5280 X 12=11,404,800 inches /15=760,320 inches. And that's it.
my teacher said its .5
is that right
i dont think he is more smart than me
thank you
It would simplify to this:
13 X sqrt(2)
7^3 * 7^-4= 7^ x 1/7^4=343 x 1/2401=343/2401=1/7
Another easier way is to ADD the exponents thus:
+3-4=-1, 7^-1=1/7
30=4x-1x
30=4x-1x=3x First subtract 4x and 1x to get 3x
30=3x
30/3=3x/3 Now divide 3 on both sides so the the 3 in 3x will cancel out with the dividing 3
10=x Now you have yoir finished problem but you may want to write it the proper way
X=10 Alrightyour all done now hope this is helpful!

30/3=x
10=x
Your answer is:
p=-3/2=-1 1/2
quite sure its 21 you retard !
Simplify and show steps for 4-2(3+2)(3+2)=2(3+2)(3+2)=(6+4)(3+2)=18+12+12+8=50
x=-15/136
How about 2/3 X9=18/3=6, which is your answer.
Well, since the store made money in one year & lost money in the two years, then we have
$1,300,000-400,000-300,000=$600,000 Net profit over 3 years. So, $600,000/3=$200,000, which is your average profit per year.OK?
x=6
2.5x10 to the power of 6
YOU MEAN (2.5 X 10)^6=244,140,625
And that's your answer!
IF YOU GAVE AN EXAMPLE, MAYBE WILL BE ABLE TO HELP YOU!
That's NOT an exponent but,sometimes,is called a "subscript", to indicate that there is another
b 2.
if 7.4p-9.2p=-2.6+5.3 what is p?
Heyy to you!
if 12d+2-3d=5 what is d?
d=1/3
if 8=(3/2)w-12+8 what is w?
Hey To You!
Yoyr answer is w=8
Just divide miles or kilometers travelled by the number of hours.
