The length and width of a rectangle are measured as 31 cm and 28 cm, respectively, with an error in measurement of at most 0.1 c
MissTica

Answer:

\Delta A = 5.9\,cm^{2}

Step-by-step explanation:

The area of an rectangle is given by the following formula:

A = w\cdot h

Where:

w - Width, in centimeters.

h - Height, in centimeters.

The differential of the expression is derived hereafter:

\Delta A  = \frac{\partial A}{\partial w} \cdot \Delta w + \frac{\partial A}{\partial h}\cdot \Delta h

\Delta A = h \cdot \Delta w + w \cdot \Delta h

\Delta A = (31\,cm)\cdot (0.1\,cm) + (28\,cm)\cdot (0.1\,cm)

\Delta A = 5.9\,cm^{2}

Kevin's net pay.
lukranit [14]

Answer:

Net pay of Kevin is $440

Step-by-step explanation:

Pay per hour = $6.50

Total Hours worked= 60 hours

Total pay for 60 hours worked = 6.50 x 60 = $390

Amount received as tips = $148

Now, his pay would be: 390+148 = $538

Amount deducted for meals = $21

Now his pay would be = 538-21 = $517

Now, Pay of Kevin is $517

Payroll taxes deducted from pay = $77

Net pay of Kevin= 517-77 = &440
