The correct equation of proportions would be $34                             x
                                                                         ------- .  Set this = to --------
                                                                          4 hr                          10 hr

$34           x
_____  = ---------    Cross multiply:  ($34)(10 hr) = 4(hr)x
 4 hr         10 hr                                                                

Cancel "hr" on both sides.  Then $340 = 4x, and x = $85.

She could earn $85 working 10 hours.

A chord of a circular clock is 48 inches long, and its midpoint is 7 inches from the center of the circle. What is the radius of
Sphinxa [80]

ANSWER

The radius is 25 inches

EXPLANATION

From the diagram, the radius of the circle is AC.

From the Pythagoras Theorem,

{r}^{2}  =  {7}^{2}  +  {24}^{2}

r^{2}  =  49 +  576

Simplify

r^{2}  = 625

Take positive square root,

r =  \sqrt{625}

r = 25

Hence the radius is 25 inches
