Answer:
20
Step-by-step explanation:
After asking so many questions of this type, I hope you understand the way to answer them.
5 types of noodles
4 choices of vegetable sides
Number of different pasta diners = 4 * 5 = 20
2 plants in a square foot
6 plants in a square yard
8 seeds per square foot
-1.17 volts
The difference between "a" and "b" generally means "a-b". Here, the difference between the potentials is ...
-0.41 V - 0.76 V = -1.17 V
_____
Sometimes, when we talk about the difference, we mean the positive difference. If that is what is intended here, it is 1.17 volts.
5:
C = 5/9(F - 32)
C = 5/9(F) - 17.777
-5/9(F) + C = -17.777
-5/9(F) = -C - 17.777
F = 5/9(C) + 32.0306
