200 - (2x) = 42
200 - 42 = 2x
158/2 = 2x/2

Step-by-step explanation:
we know that
A geometric sequence, is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

where
a_n---->
term of the sequence
r ---> is the common ratio
a ---> the first term of the sequence

Answer:
36 milliliters of rain.
Step-by-step explanation:
The rate at which rain accumluated in a bucket is given by the function:

Where r(t) is measured in milliliters per minute.
We want to find the total accumulation of rain from <em>t</em> = 0 to <em>t</em> = 3.
We can use the Net Change Theorem. So, we will integrate function <em>r</em> from <em>t</em> = 0 to <em>t</em> = 3:

Substitute:

Integrate:

Evaluate:

36 milliliters of rain accumulated in the bucket from time <em>t</em> = 0 to <em>t</em> = 3.
Answer:
$408
Step-by-step explanation:
subtract 30 from 540 to get 510
then divide 510 by 5 or divide 510 by 100 then multiply by 20
----------------------------------------------------------------------------------------------------------------
510 divided by 5 is 102
or
510 divided by 100 is 5.1 which then you multiply by 20 to get 102
----------------------------------------------------------------------------------------------------------------
102 is equal to 20% of 510 so you subtract 510 by 102 to get 408
8 would become the whole number, since there are 3 repeating numbers you would put those over 999.
So you would get 8 and 132/999
