The equation to find percent error is
where actual is the value that actually came out (in this case, 11.5 km) and theoretical is the value that was supposed to come out (in this case, 10 km). Just plug in the numbers and simplify.
So, the true answer would be 15%. Apparently, the question you're asking takes 11.5 as the theoretical and the 10 as the actual (which I personally disagree with)
If you plugged in the numbers that way, the answer comes out to 13.04%. So, the correct answer for your answer choices is c. 13%
The answer is b y = 2m - x
<span>m = </span><span>x + y2</span>
Cross multiply. Then, subtract x.
2m = x + y
<span>2m - x = y </span>
y = 2m - x<span> is correct</span>
Answer:
The Total distance she travel fro work is 30 miles .
Step-by-step explanation:
Given as :
the total time taken to cover distance = 45 minutes
Let The total distance cover = D miles
The distance cover at the speed of 32 mph = miles
The time taken to cover miles distance = hour
Distance = Speed × Time
∴ = 32 mph × h
or, = 16 miles
Again ,
The distance cover at the speed of 56 mph = miles
The time taken to cover miles distance = hour
∴ = 56 mph × h
or, = 14 miles
So , The total distance she travel for work = +
Or, The total distance she travel for work = 16 miles + 14 miles = 30 miles
Hence The Total distance she travel fro work is 30 miles . Answer
T= -8 because -8-5 equals -13
