X = 35
use the formula a^2 + b^2 = c^2 in order to find the hypotenuse, which is x.
21^2 + 28^2 = c^2
441 + 784 = c^2
1225 = c^2
35 = c
x = 35
Well here is your first part...
3.56×10^-5
Its negative so go to the left:
=.00000356
Here is your second part...
4×10^4×3×10^4
There both positive so go to the right
=40000 =30000
Then you multiply....
40000×30000=
= 1200000000
Here's your third part...
You need to divide 31 by 117
31÷117=
=0.2650%
When rolling one die, there is one "5" outcome and six total outcomes. The formula for probability is represented as:

Thus in this case, to find
, we would go about the following:

To convert
to a percent, we first multiply by 100 and then divide, as shown:

The fraction would be 1/6 and the percentage would be 16.666...%, which is often rounded to 16.67%.
4. one solution is (1, 3)
5. (1, -1)
7. -5 = x + 3
x = -5 - 3
x = -8
8. z - 4 = -8
z = -8 + 4
z = -4
3r/10? To find that we need an answer to set it equal to
