We will evaluate each case separately:
with a roller:
P1 = (40/8) * 10 + (1/2) * 10 = 55 $
spray gun:
P2 = (40/20) * (5 + 10) + (1) * (10) = 40 $
Then, the saving is:
P1-P2 = 55-40 = 15 $
answer:
you save by using the spray gun on a paint job that involves painting 40 m2 15 $
Answer: 10th Percentile
Step-by-step explanation:
The percentile of a variable in a dataset is the percentage position of the variable in the dataset such that the variables before this variable are below this percentage.
There are 20 variables in this data set and Biff scored a 65 which occupies the second and third positions on this dataset.
Picking the first position, 65 is the second variable in the data set so Biff's percentile is;
= Position on dataset/ No. of variables in data set
= 2/20
= 10%
= 10th percentile
Answer:
sin D=35
Step-by-step explanation:
Answer right on test. right answer!
Answer:
-3.2 is the opposite of 3.2
2.3 is the opposite of -2.3
1.5 is the opposite of -1.5
-5.1 is the opposite of 5.1
Step-by-step explanation:
If your value is a positive, make it a negative
Ex. 3-->-3
If your answer is a negative, make it a positive
Ex. -3-->3
You would take 175 and multiply it by 0.20 which is 35. The you would subtract 35 from 175 because it is marked down so you would get 140. Next, you would take 140 and multiply it by 0.10 and get 14. Finally subtract 14 from 140 to get your answer which would be $126.
