I'm assuming that this is applying to the linear dimensions. Let's say the paper is 10 inches by 10 inches
The new paper will be 13 inches by 13 inches since
30% of 10 = 0.3*10 = 3, and we add on 3 to 10 to get 13
Another way to see it: 130% of 10 = 1.3*10 = 13
--------------------------------------
Now decrease the paper by 30%
30% of 13 = 0.3*13 = 3.9
13 - 3.9 = 9.1
This is the same as saying 70% of 13 = 0.7*13 = 9.1
The paper is now 9.1 inches by 9.1 inches
As you can see, the paper has not been restored to its original size (10 by 10). The reason why is because 30% of a larger number leads to a bigger decrease than expected.
Let us first find how much he is spending every year, to do this let's find his monthly expense and multiply it by 12.
Every month Cameron spends 1040 + 980 + 120 = 2140
To find out how much he spends yearly, multiply the monthly value by 12,
2140 x 12 = 25680
This value is more than his net income so he clearly has a surplus, but to check we can subtract 129 from every month to get:
(1040 + 980 + 120 - 129) = 2011
2011 x 12 = 24132, which shows that his budget is saving 129 surplus every month. Choice B is correct.
Answer:
1281
Step-by-step explanation:
15% of 8540=1281
If a function is undefined, this usually means that the
value is 1 / 0.
Since tan theta is the reciprocal of cot theta.
Therefore:
cot theta = 1 / 0 = 1 / tan theta
Taking the right side:
1 / 0 = 1 / tan theta
Rearranging so that tan theta is in the numerator:
tan theta = 0
