ki77a [65]

Answer:

698.5

Step-by-step explanation:

Time-and-a-half. Time-and-a-half is payment to a worker (or workers) at 1.5 times their usual hourly rate.

11×1.5=16.5 $ per hour

16.5 ×7 =115.5 $ - total for overtime

11×2 = 22$ per hour

22×6.5= 143$ - total for double time payment

440+143+115.5 = 698.5 $ - total earnings

Evaluate each expression for a = 27 and b = 64<br> a^(−2/3) + b^(3/2)

Nana76 [90]

Answer:

The answer to your question is: $\frac{1}{9} + 6^{9}$

Step-by-step explanation:

Data

a = 27

b = 64

$a^{-2/3} + b^{3/2}$

$\frac{1}{a^{2/3} } + b^{3/2}$

$\frac{1}{27^{2/3} } + 64^{3/2}$

$\frac{1}{(3^{3})^2/3 } + (2^{6})^{3/2}$

$\frac{1} {3^{6/3} } + 6^{18/2}$

$\frac{1}{9} + 6^{9}$

Verify that( a+b)+c=a+(b+c) where a=-1/2 b=3/4 c=5/7

mojhsa [17]

Step-by-step explanation:

$(a + b) + c \\ = \bigg(- \frac{1}{2} + \frac{3}{4} \bigg ) + \frac{5}{7} \\ = \bigg(- \frac{2}{4} + \frac{3}{4} \bigg ) + \frac{5}{7} \\ = \frac{1}{4} + \frac{5}{7} \\ = \frac{7 + 20}{28} \\ \red{ \bold{\therefore \: (a + b) + c= \frac{28}{28}}}...(1) \\ \\ a + (b + c) \\ = - \frac{1}{2} + \bigg( \frac{3}{4} + \frac{5}{7} \bigg) \\ = - \frac{1}{2} + \bigg( \frac{21 + 20}{28} \bigg) \\ = - \frac{1}{2} + \frac{41}{28} \\ = \frac{ - 14 + 41}{28} \\ \red{ \bold{a + (b + c) = \frac{ 27}{28}}}....(2) \\ \\ from \: equations \: (1) \: and \: (2) \: it \: is \\ obvious \: that: \\ \: \: \: \purple{ \boxed{\bold{ (a + b )+ c = a + (b + c) }}} \\ \: \: \: hence \: verified.$
