Answer:
9801
Step-by-step explanation:
Given the general term for calculating the nth term of a sequence;
Sn = n²
Where n is the number of terms.
To find the 99th term of the sequence using the nth term of the sequence;
Since we want to get the 99th term, this means that n = 99. Substituting n = 99 into the formula we will have;
S99 = 99²
S99 = 9,801
100%/x%=125/55
(100/x)*x=(125/55)*x - we multiply both sides of the equation by x
100=2.27272727273*x - we divide both sides of the equation by (2.27272727273) to get x
100/2.27272727273=x
44=x
x=44 So your answer is 44 ^-^
<span>Express 342,000,000,000 in scientific notation
</span>342,000,000,000 = 3.42 x 10^11
10x -4 (x - 2) = 80
10x + (8 + -4x) = 80
<span>8 + 10x + -4x = 80
</span>8 + 6x = 80
<span>8 + -8 + 6x = 80 + -8
</span><span>6x = 80 + -8
</span>6x = 72
<span>x = 12</span>
