100.80 kg - 20.35 kg = 80.45 kg . . . . the new weight of the bag
It's a pretty straightforward subtraction problem. As with any decimal addition or subtraction, you line up the decimal points and extend any numbers with zeros to make the number of decimal places match.
Answer:
belongs to the line 
. Please see attachment below to know the graph of the line.
Step-by-step explanation:
From Analytical Geometry we know that a line is represented by this formula:
Where:
- Independent variable, dimensionless.
- Dependent variable, dimensionless.
- Slope, dimensionless.
- y-Intercept, dimensionless.
If we know that 
, 
and 
, then we clear slope and solve the resulting expression:
Then, we conclude that point belongs to the line , whose graph is presented below.
Answer:
Cluster Random Sample
Step-by-step explanation:
another example should help
Example—An airline company wants to survey its customers one day. So they randomly select 5 flights that day and survey every passenger on those flights, it's a cluster random Sample
it's kinda similar

There are 11.3 yards in 33.9 feet!
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
recall that any radical expression 
has real solutions only if A is not negative. (otherwise you will have imaginary solutions)
hence in this case we have
,
for real solutions, 8x must be ≥ 0,
since 8 is a positive number, x must be ≥ 0 (answer)
