Julio is paid 1.4 times his normal hourly rate for each hour he works over 30 hours in a week. Last week he worked 35 hours and
Harman [31]
<span>Julio is paid 1.4 times his normal hourly rate for every excess hour he works in a week.
last week he worked 35 hours and got 436.60 dollars.
We need to find an equation so we can be able to solve Julio’s earnings:
=> Let X be the value of Julio’s rate
=> 30 * X + 5 x 1.4x = 436.6
=> 30x + 7x = 436.6
=> 37x = 436.6
=> 37x / 37 = 436.6 / 37
=> x = 11.8
Thus the original rate of Julio is 11.8 dollars
=> 1.4 x 11.8 = 16.52 dollars, the rate of Julio with added rate
=> 30 x 11.8  + 5 x 16.52
=> 354 + 82.6
=> 436.6

20 POINTS and it has to be correct. This depends on if I pass or fail
valentina_108 [34]

Answer:

(x+8)^{2}+(y-14)^{2}=19

Step-by-step explanation:

The equation of a circle is: (x-x_1)^{2}+(y-y_1)^{2}=r^2 , where x_1 is the x coordinate of the center, y_1 is the y coordinate of the center, and r is the radius.

In this case, x_1 = -8, y_1 = 14, and r = 4.3589. Plugging these into the equation, we get:

(x+8)^{2}+(y-14)^{2}=4.3589^2

If you want, you can round 4.3589^2 to 19.

Then, the answer would be: (x+8)^{2}+(y-14)^{2}=19 .

Hope this helps!
