.12 times 18\n.16 times 24 (2 years in months)\n.05 times 120 (10 years in months)\n\nfrom there you can convet to weeks by multiplying by 4, days by multiplying by 4 then by 7.

x is age 5 years ago.  so x = 7.  age now is x + 5 = 12

3.2 + 10% = 3.2 + 0.32 = 3.52

x = youngest\n2x = oldest\ny = middle\nx + y = 2x + 3\nx + y + 2x = 19\n\nUse these two simultaneous equations to solve for each variable.\n\nx + y = 2x + 3\ny = x + 3; use this to substitute into the other equation\n\nx + (x + 3) + 2x = 19\n4x + 3 = 19\n4x = 16\nx = 4; substitute into above statement\n\ny = x + 3\ny = 4 + 3 = 7\n\nSo the ages of the children are 4, 7, and 8

20*sqrt(1-.8*.8) = 12ly\n\n12ly/.8c = 15 years.

Amount after 1st 6 months \n= $ 2000 + 7%/2 of $2000\n= $2000(1 + 0.035)\n= $2000(1.035)\nAmount after 2nd six months \n= $2000(1.035) + 7%/2 of  $2000(1.035)\n= $2000(1.035)²\n= $2142.45

52x \n\nthere are 52 weeks in 1 year.  so you multiply 52 (the # of weeks by X the # of years

just divide the given amount with the total amount and multiply it with 100. You will get the %age \nFor Example 63 out of 70 means\n(63/70)*100 = 90%

its actually really simple to figure out 15%.  10% of 520 is obviously 52 (just move the decimal over one place, thereby removing the zero) and since u need 15%, you need 10%+ 5%, right?  so half of the 10% (52) is 5% which is 26.  Now add 52 and 26 and u get 78!   even if ur totally not a math person, dont get thrown off, any percent ending in a zero or 5 (10, 25, 50 etc) are really simple to do this way!

Okay, so you know there are 12 months in a year. And every year, her sales increases 15%. If you want to find out how much percent her sales increase every month, you just need to divide 15% by 12, which is: 1.25%. So, this means that her sales increase 1.25% every month. \n\nNow, in January her total is $186,000, what is 1.25% of that? \n$186,000/100= $1,860 \n$1,860*1.25= 2325\n\nSo this means that her sales for February will be $2325 more than her sales from January. Her total for February is $188,325\n\nTo find her total for March, you need to find 1.25% of her total from February, so that is 1.25% of $188,325. Find that out yourself.\n\nTo find her total for April, you need to find 1.25% of her total from March. And add it to that total. (from March)\n\nAnd so on. \n\nI think this is how you solve this.\n\nGood luck.

its 6 months.. since there is 2 six month periods in a year. Semi is two and annually is the whole year.. so 6+6=12

B.\n\nBut it is not actually correct.  %'s are generally figured on a standard 360 day calendar year, this problem uses 365

[ 6 (3 - 2m) ] / 5  =  m + 4\nexpand brackets\n(18 - 12m) / 5 = m + 4\nmultiply both sides by 5\n18 - 12m = 5m + 20\ncollect like terms\n-12m - 5m = 20 - 18\n-17m = 2\n\nm = -(2/17)

The answer is D = 12%.\n\nThe way to do the math is with the following assumptions:\n\nPresent value = 404 (given)\nFuture value = 1,000 (par)\nPayment = 0 (zero coupon bond)\nNumber of time periods = 8 (given)\n\nSolve for the interest rate.\n\nThe way to check your answer is simply to use the equation:\n404 * (1.12) ^ 8 = $1000 so we know that 12% is correct!

Take your 5% and divide by 12 to get your monthly percent.  From there, it's a matter of multiplying the number 12 times to get the annual percent.

It is converting months as a fraction of the year.\nThere are twelve months in a year.so if month is to be exppressed as a fraction of a year it can be done as under\n1month is 1/12 th of a year that is        0.0833\n2months   2/12 (1/6)th of a year that is   0.1666\n3         3/12 (1/4)                       0.2500\n4         4/12 (1/3)                       0.3333\n5         5/12                             0.4250\n6         6/12 (1/2)                       0.5000\n7         7/12                             0.5833\n8         8/12 (2/3)                       0.6666\n9         9/12 (3/4)                       0.7500\n10       10/12 (5/6)                       0.8333\n11       11/12                             0.9166\n\nI am unable to understand how you say 3 month is 0.75 %\nIt is nine month which is 3/4  that is 0.75 or 75/100
