Suppose
At the same time, we can write
Note that 
(just reverse the sum). Let's pair the first terms of 
and 
, and the second, and the third, and so on:
Now, each grouped term in the sum on the right side adds to 151. There are 52 grouped terms on that same side (because there are 50 numbers in the range of integers 51-100, plus 50 and 101), which menas
But , as we pointed out, so
Answer:
$2.76
Step-by-step explanation:
9/3.25=2.76
Answer:
40.7m^2
Step-by-step explanation:
Base×Height= 5.2m×3=15.6m2
Area of semicircle= Pie r^2= Pie×4^2=16×pie
pie×16÷2=8×pie
8×3.14=25.12m2
15.6m2+25.12m2=40.72m2
rounded to nearest tenth=40.7m2
The answer to X is = 369700
