Answer:
-1 - ( -2 ) = 1
Step-by-step explanation:
The formula for percent error is:
((Approximate value - exact value) / exact value) x 100
1) 14-12 = 2
2/12 = 0.1666
0.166 x 100 = 16.7% (Rounded to nearest tenth)
2) 231 - 215 = 16
16/215 = 0.74419
0.74419 x 100 = 7.4419% ( Round as needed)
3) 17.1 - 16.5 = 0.6
0.6/16.5 = 0.36364
0.36364 x 100 = 3.6364% (Round off as needed)
4) 1081 - 1150 = -69
-69/1150 = -0.06
-0.06 x 100 = -6% = 6% error
$20-$5=$15
$15/$2.50= 6
So he can go 6 miles after he pays the $5 fee
Answer:
The answer is actually....
Step-by-step explanation:
20+4y
7 minutes every 4 days
7/4min every day
times 10
70/4min total
times 60 because 60 secods per minute
4200/4=seconds=1050 seconds
gains 1050 seconds
