I’m not sure if I am correct ,

Informally, each hour of overtime is like 2.5 hours of regular time, so 8 hours of overtime is like 8*2.5 = 20 hours of regular time.

So her $1470 earnings are for 40+20 = 60 hours of work.

Her regular hourly wage is 1470$/60=24.5 dollars

40(x)+8(2.5x)=1470
40x+20x=1470
60x=1470
X=1470/60
X=24.5 dollars

Answer =24.5$

A falling object travels a distance given by the formula
sergeinik [125]

Answer:

The time taken by object to travel 21 ft is 1 sec

Step-by-step explanation:

The distance travel by falling object given as

d = 5 t + 16 t²

The Distance cover by object to travel = 21 ft

so , from Distance time equation

21 = 5 t + 16 t²  

or, 16 t² + 5 t - 21 = 0

Or, 16 t² - 16 t +21 t - 21 = 0

Or, 16 t ( t - 1) + 21 (t - 1) = 0

Or.   (t - 1) (16 t + 21) = 0

Or,  (t - 1) = 0   And   (16 t + 21) = 0

∴      t = 1         And   t = (  \frac{-21}{16}  )

Hence The time taken by object to travel 21 ft is 1 sec Answer
