Answer: For the first one, 1.22 x 105. For the second one, 2.
Step-by-step explanation:
For the 1st one, this asks for the sum. Also, since both terms are greater than 5 (excluding the SCI notation of 10), they should get into the next power. So cross out the first two. Now for the last two, when you add, you get 11.56. When you round that AFTER changing the 11.56 to 1.56 and increasing the exponent of 104 to 105, you should have rounded it to 1.2, since that is the least amount of significant digits. The correct answer is 1.2 x 105 lbs.
For the second one, it is pretty simple, significant digits are determined by the least amount of digits in the factors/addends. The least amount seen is 2, which is in the number 2.8.

25=r6 and I don’t know how to write the rest but yeah
His location would be 20 feet above the sea level because...
30+-10= 20 because adding a negative to a positive is basically like subtracting.
Can have a brainliest answer now please?
67 multiplied by 3 is 201, so there is 201 people in the age group 12-29. Also, 67% is approximately two thirds, and we can see that reflected in our answer.
