Answer:
416.7pounds
Step-by-step explanation:
Given parameters:
Weight of the small box = 125pounds
Unknown:
Weight of the larger box = ?
Solution:
The large box weighs times as the small box:
So;
= 125pounds x
= 416.7pounds
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
Given expression is
Radical is fourth root
first we simplify the terms inside the radical
So the expression becomes
Now we take fourth root
We cannot simplify fourth root (y^2)
After simplification , expression becomes
Answer is option B
