Nina works at an hourly rate of $12.25 per hour and worked 46 hours last week. She earns overtime for hours exceeding 40 hours.

Alenkinab [10]

Answer:

$600.25

Step-by-step explanation:

12.25 per week

46hrs last week

40+ = overtime

Overtime = t*1.5

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

46-40= 6hrs of overtime

40*12.25= 490 - this is her money for working 40hrs.

To figure out the money amount of overtime pay--- 12.25*1.5= 18.375 (18.38)

18.38*6= 110.25

add now

110.25+490= $600.25

=) ~i hope i helped~ =)

Solve triangle PQR is PQ 9, PR 7, and QR 8. POR is NOT a right triangle.

zimovet [89]

Given => PQ = 9 unit
PR = 7 unit
QR = 8 unit

To find => Area of triangle PQR

We can find area of triangle by Heron's Formula.

Where,

s = (9+7+8)/3

= 24/3

= 8

and,
a = 9
b = 7
c = 8

Heron's Formula = $\sqrt{s(s - a)(s - b)(s - c)}$

= $\sqrt{8(8 - 9)(8 - 7)(8 - 8)}$

= $\sqrt{8( - 1)(1)}$

= $\sqrt{ - 8}$

= $2i \sqrt{2}$

Area of triangle = 2i√2 units

Hope this helps!
