a 50 kg sack rice is being pulled by a farmer the force causes the sack to accelerate at 5m/s2 . calculate the net force that produced the acceleration
Force = mass * acceleration = 50*5 = 250N (This is on a horizontal surface and friction has not been taken into consideration)

Alexander went to his ATM and drew out a large amount of money for his expenses. For Christmas presents for his family, he spent $15 more on books than on CDs, which cost $15 more than toys. Cards were one-fifth the cost of toys and one-third the cost of calendars, which were $36. Alexander now had $27 left.
Alexander bought
books, cds,toys,cards,and calenders
calenders = $36
cards were 1/3 the cost of the calenders = $12
cards were 1/5th the cost of toys, which means that the toys were 5 times more than the cards. So toys = $60
cds cost $15 more than toys so cds=$75
Books cost $15 more than CDs so books = $90
Total cost = $273
How much did he get from the ATM? $273+$27 = $300

what is the square root of 12 ?
root12 = root(4*3) = root4 * root3 = 2root3 (This is root12 simplified)
But countrygirl is also correct. She has provided an approximation correct to 2 decimal places.

12 to 3 odds that you cannot roll two even numbers with the roll of two fair dice. What can you expect if you play 200 times
I think that this question is riddled with errors.
There are 36 number combinations that you can get when you roll 2 dice. (different coloured dice)
9 of those are have 2 even numbers.
So the odds of NOT getting 2 even numbers is 27 to 9. OR 3:1 (read as 3 to 1)
The probability of NOT getting 2 even numbers is 27/36 = 3/4 (read as 3 in 4)
If I roll the 2 dice I would expect to get approx 3/4*200 = 150 rolls where the numbers are NOT both even.

what is the domain of x^2-4/x^2-4x-1?
domain is all x where x is not equal to 0 (because you can't divide by 0)

It probably looks like a b/c
It is supposed to look like a mixed numeral only with letters.

A contractor wants to use 34 feet of molding, cut into three pieces, to trim the sides and top of a garage door. The long piece is 1.5 feet longer than three times the length of each shorter piece. Find the length of each piece.
Sounds like the short pieces are both the same length. Let them each be x feet long.
Three times the short piece is 3x feet
The long piece is 1.5 feet longer than 3 times the short piece. That must be 3x+1.5 feet
Add them all together and you get
x+x+3x+1.5 = 34
then you solve the equation to get the value of x.

The subway train offers access to all twelve intersections downtown. If every intersection is .75 miles apart and the train travels at 20 mph and spends 45 seconds at every stop to unload and onboard new customers, how long will it take to get from the first intersection to the last intersection?
When you do a question like this use a similar smaller question to see what is happening.
I h ave given you my solution to an alternate question.
I decided to look at the same question but with only 4 stop. I draw the train line on a piece of paper.
The distance travelled was 0.75*3 = 2.25miles
1hour/20miles * 2.25miles = 0.1125hours = 0.1125*60min = 6.75minutes = 6 minutes and 45 seconds
The number of stops where the train waited was only 2 because the first and last don't count.
stops = 2*45seconds = 90seconds = 1 minute and 30 seconds
6 minutes and 45 seconds + 1 minute and 30 seconds = 8minutes and 15 seconds.
This answer is for 4 stops only.
Try copying the method only do it for the whole 12 stops.
When I did it i got 32minutes and 15seconds but I haven't checked my working so if you get a different answer it doesn't necessarily mean that you are wrong.
Good luck. If you do some but get stuck you can ask for help again.

It is quite simply a question that does not have a solid answer. Depending on the size of these animals. Miniature pigs could not equal up to a cow with just two, however large pigs may only need one and a quarter.

(12/81)/x=4/9
(12/81)*(1/x)=4/9
multiply both sides by x (to get x off the bottom)
then
multiply both sides by 9/4 (to get x by itself)
now get the answer on your calculator.

Since the cost of the music plan per year is $9.99 regardless of how many songs you download, we must first subtract $9.99 from the total cost of $113.74.
$113.74 - $9.99 = $103.75
This leaves us with the amount spent above and beyond the original fee, and thus amount we spent on individual songs downloaded. We have only to divide this amount by the cost of an individual song ($0.25) to find the number of songs that were downloaded.
$103.75 / $0.25 = 415 Songs
And there is your answer. I hope I helped.
