The range of possible values of the measurement is:
[45.97cm, 48.03cm]
<h3>Which is the possible range for the measurement?</h3>
Here we have the measurement:
measurement 47 cm ± 2.2%
The 2.2 percent of 47cm is:
47cm*( 2.2%/100%) = 47cm*(0.022) = 1.034 cm
Then the minimum of the measurement is:
47cm - 1.034cm = 45.97cm
The maximum of the measurement is:
47cm + 1.034cm = 48.03cm
we conclude that the correct option is the second one:
[45.97cm, 48.03cm]

Answer:
the total surface area is 40 + 12 + 15 = 67 square units
Step-by-step explanation:
Refer to the diagram:
the combined area of the top and bottom is 2(5·4) = 40:
the combined area of the ends is 2(1.5·4) = 12; and
the combined area of the front and back is 2( 5 · 1.5) = 15
and so the total surface area is 40 + 12 + 15 = 67 square units
Y=-4X+1 the equation can be anything without a specific x-in’t
The distance formula is: Distance = Rate x Time.
We know the distance: 2000 miles.
We know the rates: 560 and 500 mph.
We need to solve for time:
2000 = (560 + 500) * T
2000 = 1060 *T
T = 2000 / 1060
T = 1.89 hours ( 1 hour 53 minutes)
They left at noon:
12:00 pm + 1 hour and 53 minutes = 1:53 pm.
