Answer:
The mass of the grains = 120 ± 1 g
Step-by-step explanation:
we are given the following:
Total mass of container + grains = 185 grams
Mass of container = 65 grams
Therefore, mass of grains is calculated as follows:
Mass of grains = ( Mass of container + grains) - mass of container
= 185 - 65 = 120 grams.
since the scale has an absolute uncertainty of 1 g, the mass of the grains is written as 120 ± 1 g
The easiest way to do this is find the area of the large rectangle and subtract the two missing pieces. The length of the large rectangle is 24 and its height is 16. 24x16=384. The area is each of the two missing pieces is 2x2=4. Since there are two of them multiply by two 4x2=8. Then subtract eight from the first area calculated. 384-8=376 square meters
The value of root 10 is between 3 and 3.5

Answer:
$65.60
Step-by-step explanation:
4×16.40 = 4×(16+0.40) = (4×16) + (4×0.40) = 64 + 1.60 = 65.60
