Personally, I never bothered learning the formula.
When I run into a problem like this, I look at it this way:
(I learned this method from my high school math teacher,
Mr. H. Carlisle Taylor, in 1956. It not only works, but I can
even understand it !)
The first object can be any one of the 8 . For each of those ...
The 2nd object can be any one of the other 7. For each of those ...
The 3rd object can be any one of the other 6 . For each of those ...
The 4th object can be any one of the other 5 . For each of those ...
The 5th object can be any one of the other 4 . For each of those ...
The 6th object can be any one of the other 3 . For each of those ...
The 7th object can be any one of the other 2 . For each of those ...
The 8th object has to be the 1 that's left.
Total number of possible ways to line them up is
(8 x 7 x 6 x 5 x 4 x 3 x 2 x 1) = 40,320 ways .
To solve this you need to put 5.3 over 8 to represent the first lamp post then you need to put x over 128, so you can find the height of the lamp post. The lamp post is 84 feet and 8 inches
Hi there!
First, let's use a proportion to figure out the commission the salesperson makes.
WORK:
x/15486 = 3/100
100x = 46458
x = 464.58 (commission)
Next, we'll add together the commission and her salary.
WORK:
464.58 + 1200 = 1664.58
ANSWER:
$1664.58
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Slope of the line passing through (7,-5) and (3,11) =

= -4
As two lines are perpendicular to each other, so when their slopes are multiply by each other, the answer will be -1
so the slope of the line passing through (-3,-9) and (5,n) will be

So will will get a formula below

and the answer will be n=
The distance that Sam ran is 14 km
