Answer:

SA: 664 in²

LA: it’s supposed to be 1040cm???

Step-by-step explanation:

SA: find the area of all sides of the prism first (I suppose it’s rectangular?)

80+80+112+112+140+140 = 664

LA: the lateral area formula is (perimeter of base)*height...

perimeter of base = (6+6+14+14) = 40

40 * 26 = 1040

I may be wrong on the second one since I don’t know what the prism’s shape is... Hope it helps though ;)

Roxanna earns 1.5 her normal hourly rate for overtime pay. Last week, Roxanna earned $72.00 in overtime pay for 4 hours. What is

yan [13]

Roxanna's normal hourly pay is $ 12

<u>Solution:</u>

Lets assume Roxanna's normal hourly pay = "x"

As overtime pay is 1.5 times of normal pay

So Roxanna's overtime hourly pay = $x \times 1.5 = 1.5x$

Also given in 4 hours, in overtime Roxanna earned $72.00

So in 1 hour, in overtime Roxanna earned = $\frac{72}{4} = 18$

That means Roxanna's overtime hourly pay = 18

Also we have calculated Roxanna's overtime hourly pay in terms of "x" that is 1.5x

=> 1.5x = 18

=> $x = \frac{18}{1.5} = 12$

Roxanna’s normal hourly pay = x = $12
