Answer:
The percent error in the speeds are 7.1428 %.
Step-by-step explanation:
The percent error of any value is found by,
<em>Here, the reading value is 60 mph and the correct value is 56 mph.</em>
Hence inserting this value in above equation, we get
<em>Hence, the percent error in the speeds are, 7.1428 %.</em>
Answer:
$40
Step-by-step explanation:
If it was 20% off, you are paying 80% of the original price.
So .80 * Original price = $32
32/.8 = 40
The information of the table permits you to state these equations:
10x + 9 y = 47
25x + 12 y = 86
16x + 12 y = 68
By subtracting the third equation from the first, you get:
9x = 18
=> x = 18 / 9 = 2
Now using any of the equations you can obtain the value of y.
I will use the first equation:
10x + 9y = 47 => 9y = 47 - 10 (2) = 27
=> y = 27 / 3 = 3
Those results are interpreted as they charge $2 for each plain wrapping and $3 for each decorative wrapping.
Then, the correct choice is " the team charged $2 to wrap a gift with no bow and $3 to wrap a gift with no bow"
