Answer:
|96.55−0.02|= x
|96.55+0.02|=x
Step-by-step explanation:
Given that:
Measured length of beam = 96.55 cm
Measurement accuracy = plus or minus (± 0.02cm)
Limits of actual length of the beam:
Let limit of actual length = x
Lower limit :
|measured length - accuracy| = x
|96.55 - 0.02| = x
96.53) x
Upper limit :
|measured length + accuracy| = x
|96.55 + 0.02| = x
96.57 = x
Since it is 4 times as many quarters and dimes, you can use a chart for guess and check. I started with 8 dimes and 32 quarters.
If you keep going, you end up with the fact that there are 36 quarters and 9 dimes.
Multiplicative identity, which states that anything multiplied by 1 is itself.
I think b but I’m not completely sure
