The length of the shorter wire is 12 cm
Step-by-step explanation:
Let us assume that the 27 cm wire is cut into two pieces of length x cm and so the longer part would be x+3 cm.
Now we know that the total length of the wire is 27cm so
x+(x+3) = 27
2x+3 = 27
2x = 27-3
2x = 24
x = 12 cm
First, let's find the unit rate:
9.50 / 10 = 0.95
Now we multiply the unit rate by 84
0.95 * 84 = 79.80
It would cost $79.80
Answer:
Alcohol
Step-by-step explanation:
Alcohol would be more suitable for making measurements in a -60 degree laboratory, since its boiling point is 78 degrees and its freezing point is -80 degrees, meaning alcohol will not freeze in a -60 degree environment.
Mercury on the other hand, has a freezing point of -39. Thus, it will freeze in a -60 degree environment, making it not suitable for use in this laboratory.
