Answer:
13.74
Step-by-step explanation:
3.59+5.15+1.99+1.99=12.72 total without tax
12.72x1.08 (includes 8% sales tax)=13.74
Maybe something like 811.1?
Answer: Angle 2
The 7.5 cm side is opposite angle 2, so opposite = 7.5
The 18 cm side is adjacent to angle 2, so adjacent = 18
Therefore, tan(angle 2) = opposite/adjacent = 7.5/18
Replace "angle 2" with "A" and we have tan(A) = 7.5/18
Answer:
The percent error based on the average measurements is 0.8%.
Step-by-step explanation:
The standard equation for percent error is [(original - actual)/original} x 100. The original amount is 100 degrees celcius. Your average measurement can be found by adding the three temperatures together and dividing by the number of temperatures collected: 98.5 + 99.3 + 99.8 = 297.63/3 = 99.2. When we place our numbers into the equation and solve, we get: (100 - 99.2)/100 = 0.008 x 100 (to get our percentage) = 0.8%.
