Answer:
C. you can not prove that the triangles are congruent
Step-by-step explanation:
- The answer can not be SAS becuase although the congruent angle is not in between the two congruent sides.
- It can not be AAS because only one angle is congruent.
- It can not be SSS because all three sides are not congruent.
Answer : The answer is option c evaporation
The annual interest owed is
... 7% × $115,000 ≈ $8050
The monthly interest owed is 1/12 that amount.
... (1/12) × $8050 ≈ $671
_____
Some calculators are able to use 7% as a factor; others require you use the decimal equivalent, 0.07.
A=1/10, b=1/12, c=1/15 (these are the rates for each worker...)
1.)
2(1/10)+4(1/12)+t/15=1
1/5+1/3+t/15=1
(3+5+t)/15=1
3+5+t=15
8+t=15
t=7
So it would take c 7 hours to finish the job.
2.)
1/40-1/60
(3-2)/120
1/120
The drain rate is 1/60. So you will need to find t when the tank is empty, while starting at 2/3 capacity...
2/3-t/60=0
(40-t)/60=0
40-t=0
t=40
It would take 40 minutes to empty the tank when it is 2/3 full.
