Answer:

$165.60 overtime money only

$736 regular time only

added together (gross income)

$901.60

Step-by-step explanation:

46hrs
18.40 an hr
hrs over 40 = overtime= *1.5

To figure out if there is any overtime here, we subtract.

46-40= 6hrs of overtime

To figure out the amount of cash gained for regular time, we multiply.

40*18.40 = 736

----------------

We need to know how much money is paid per overtime hour.

18.40*1.5 = 27.60

To figure out the amount of cash gained during overtime, we multiply.

6*27.60 = 165.60

add for gross income (total earnings)

165.60+736 = 901.60

Find the Expression OF this equation. c/3 / ac/4 QUESTION C

Fiesta28 [93]

Answer:

See below

Step-by-step explanation:

$(a) \: \: x = \frac{c}{3} \\ \\ \implies \: {x}^{2} = { \bigg( \frac{c}{3} \bigg) }^{2} \\ \\ \bold{\implies \: {x}^{2} = \frac{ {c}^{2} }{9} } \\ \\ (b) \: \: x + y = \frac{c}{3} + \frac{ac}{4} \\ \\\implies \: \bold{x + y = \frac{4c + 3ac}{12} } \\ \\ \frac{xy}{z} = \frac{ \frac{c}{3} \times \frac{ac}{4} }{ \frac{ {a}^{2} }{2c + 1} } \\ \\ = \frac{ \frac{ac ^{2} }{12} }{ \frac{ {a}^{2} }{2c + 1} } \\ \\ = \frac{a {c}^{2} }{12} \times \frac{2c + 1}{ {a}^{2} } \\ \\ \implies\bold{\frac{xy}{z} = \frac{ {c}^{2}(2c + 1) }{12a} }$
