Answer:percent error in Joey's measurement to the nearest 10th of a percent =- 4.6%
Step-by-step explanation:
Step 1
Time as recorded by the stopwatch = 4.82 seconds
Real Time it takes for a Frisbee to fly through the air =5.05 seconds
percent error = Measured value – True Value /True value x 100.
= 4.82 - 5.05 / 5.05 x 100
=-0.23/5.05
=-0.0455 x 100
=4.5544%
Rounding to nearest 10th of a percent = - 4.6%
With a line parallel to a side through a triangle we get similar triangles so a proportion.
AC : BC = AQ : PQ
AC = BC AQ / PQ
AC = 12.6 (7.2) / 8.4
AC = 10.8 cm
Answer: 10.8 cm
$300 income
$250 + $100 = $350 expenses
$300 - $350 = a loss of $50
Take the amount 14 MPG (miles per gallon)
Then take the number of miles to go (133 miles to go)
Divide, like so:
133/14
= 9.5
