Step-by-step explanation:
2√48= 13.86
3√147= 36.37
Perimeter: 13.86+13.86+36.37+36.37= 100.46
Answer:
Step-by-step explanation:
The fidelity investment mutual funds is $10.92 per share.
The fund charges 2.5%.
So, if 2.5% is charged,
Then, 2.5% of the share is
2.5% of $10.92 = 2.5 / 100 × $10.92
2.5% of $10.92 = $0.273
Then, total offer price is 0.273 + 10.92
Therefore, total offer is $11.193
How about raising 286 up by 14 to 300 and compensating by lowering 428 by the same 14 Since I know that 14 + 14 is 28 then 28-14 is 14
So 428 - 14 = 414
So now I have 414 + 300 which I can do mentally - the answer is 714 and is also the answer to the original problem 428 + 286
Compensation works very well - bring one number up or down to a rounded number and compensate by doing the opposite to the other - instead of 199 + 457 - try 200 + 456
Same answer and because one of the numbers is nicely rounded, it is easy to add the other.
One more: 207 + 182 becomes 200 + 189 =389 I lowered one by 7 and raised the other one by the same 7.
