<u>Answer:</u> The final answer must have only one decimal place.
<u>Step-by-step explanation:</u>
Significant figures are defined as the figures present in a number that expresses the magnitude of a quantity to a specific degree of accuracy.
We are given:
An addition problem having values (34.530 g + 12.1 g + 1222.34 g)
<u>The rule that is applied for the addition and subtraction is:</u>
The least precise number present after the decimal point determines the number of significant figures in the answer.
For the given problem, the least precise number after the decimal is '1'
Evaluating the value: (34.530 g + 12.1 g + 1222.34 g) = 1268.97 ≈ 1269.0
Hence, the final answer must have only one decimal place.
Im pretty sure the answer is 80%.
The answer would be 8.71 because 8.7 is a rounded answer of 8.70
if you add 1 to 70 you would get 71 so the answer is 8.71
Answer:
diameter-- last picture on right side
radius-second last picture on right side
πd=2πr
2r=d/2
Step-by-step explanation:
diameter is a line segment that goes through the center of a circle
this will match to the last image on the right side
radius is half of the diameter or from a point on the outer edge of the circle to the center
this will match to the second one on the right side
πd-- d=2*radius
2πr
2r=d/2
because radius is half of the diameter
I don't see what we need to multiply but here is an example: the numbers of the equation that I'm doing is 12 times 13 and this is how I do it .
(1)(2) Step 1: multiply 3 times 2 then when you get the
x 1 (3) answer you would need to multiply then 2 times 3.
-------
(36) ( when multiplying 1 times 3 and then multiply 2 times 3)
Step 3: know that in the third step you would need to multiply 1 times 2 then 1 times 1.
(1)(2)
x(1) 3
-------------
36
+ 120 (when multiplying 1 times 2 then 1 times 1 but I added a zero )
-----------
156 ( I add them all up and that's the answer )
