2 workers 8 dollars per hour and 40 hours
mutiply
2*8*40=640 dollars
now costlabor/revenue (try to get to percent which is parts out of 100 so x%=x/100)
640/2000
64/200
32/100=32%
answer is 32%
Answer:
-14x+4
Step-by-step explanation:
So the first set of paranthese don't really matter so you can rewrite it to this
-7+6-(-2x+9x-2)
Then infront of the ( there is a - which means a -1. Now just do the disbutive property.
-7x+6+2x-9x+2
Now add like terms and you get your finial answer!
-14x+4
Answer:
8 inches
Step-by-step explanation:
Nacho cheese
v= Pi×radius×2×height
v = 3.14×8×2×4 = 200.96
jalapeño
3.14×4×2=25.12
200.96÷25.12=8
the height is 8
to check your work you can do
(multiply by 8 and see if it equals 200.96)
3.14×4×2×8 = 200.96
since the volume is the same as the volume for nacho cheese we can say that 8 inches for height is correct
Answer:
40 drops
Approximately 0.166 %
Step-by-step explanation:
It would be easier to work the same units for volume
Since there are 1000 ml in a liter
Original water volume 1.2 L = 1.2 x 1000 = 1200 mLl
The final volume of the acid-water solution = 1.202 L = 1202 mL
So total volume of acid added = 1202-1200 = 2 mL
Each drop of acid is 0.05 mL
Number of drops added = 2/.05 = 40 drops
Percent of acid in acid solution = (Volume of acid added)/(Final volume) x 100 = (2/1202) ≈ 0.00166 x 100 ≈ 0.166 %
The answer would be 1/100 or 0.01
