Answer:

Step-by-step explanation:  First, multiply the $81 by the 10% (81 x .10 = 8.1). Next, use the answer from step one and subtract it from the $81 (81 - 8.1 = 72.90) . $72.90 will be your final answer.

Naddik [55]

Answer:

30

Step-by-step explanation:

3x - 27 = x +11

3x -27 +27 = 11 + 27

3x - x = x -x + 38

2x = 38

2x ÷ 2 = 38

X = 19

Julio is paid 1.4 times his normal hourly rate for each hour he works over 32 hours in a week. Last week he worked 43 hours and
nekit [7.7K]

Answer:

r = \$14.71

Step-by-step explanation:

Given

Normal Hour = 32 hours

Overtime = Hours above 32

Rate for Overtime = 1.4 times normal rate

Earnings = $535.62

Required

Determine the normal hour pay

First, we need to determine the hours worked overtime.

This is:

Overtime = 43 - 32

Overtime = 11

The equation that binds all the parameters is:

Earnings = Normal\ Hour * Normal\ Rate + Overtime * Overtime\ Rate

This gives:

535.62 = 21 * r + 11 * 1.4r

535.62 = 21r + 15.4r

535.62 = 36.4r

Solve for r

r = 535.62/36.4

r = \$14.71

The position of a particle on the x-axis at time t, t > 0, is s(t) = ln(t) with t measured in seconds and s(t) measured in fe
Mrrafil [7]

Answer:

C.<em> </em><em>The quotient of the natural logarithm of 2 and e.</em>

Step-by-step explanation:

The position of a particle on the x-axis at time t, t > 0, is given by

s(t) = \ln(t)

with t is in seconds and s(t) is in feet.

The rate of change is,

=\dfrac{f(b)-f(a)}{b-a}

So rate of change of position or average velocity, for e ≤ t ≤ 2e will be,

=\dfrac{\ln2e-\ln e}{2e-e}

=\dfrac{\ln2e-\ln e}{e}

=\dfrac{\ln\frac{2e}{e}}{e}

=\dfrac{\ln2}{e}

Therefore, option C is the correct answer.
