Answer:
36.9%
Step-by-step explanation:
The formula for Percent Error =
[|Approximate value - Actual value|/ Actual value ] × 100
Approximate value = 35 minutes
Actual value = 55.5 minutes
Percent Error =[ |35 - 55.5|/55.5] × 100
Percent Error = |-20.5|/55.5 × 100
Percent Error = 20.5/55.5 × 100
Percent Error = 36.936936937%
Approximately to the nearest tenth = 36.9%
-14+3/2b-(1+2/8b), then take out the blanket become -14+3/2b-1-2/8b , get 5/4b-15=0 so 5/4b=15 ,get b=15×4÷5. b=12
