Answer:

854.88 lb/yr

Step-by-step explanation:

It is effectively a units conversion problem. The conversion factors of interest are ...

1000 W × 1 h = 1 kWh

52 wk = 1 yr

(1500 W)×(8 h/wk) × (52wk/yr) ÷ ((1000 W)(1 h))/(1 kWh) × (1.37 lb/kWh)

= (1500×8×52×1.37)/(1000) lb/yr

= 854.88 lb/yr

using alternate interior angles theorem on angles A and C, verticle angles theorem on angle O, and the Parallelogram Diagonals Theorem Converse you can prove triangles ADO and BOC are similar. Then using CPCTC "Corresponding parts of congruent triangles are congruent" you can prove that line segment AO is congruent (equal) to line segment CO

Answer:

$\rm x=\frac{46}{3}$

$\rm y=-\frac{25}{24}$

Step-by-step explanation:

$\huge\begin{array} {|c|} \hline\left. \begin{cases} { \rm\frac{ 1 }{ 4 } x+ \frac{ 4 }{ 5 } y = 3 } \\ { \rm\frac{ 5 }{ 16 } x- \frac{ 1 }{ 5 } y=5 } \end{cases} \right. \\ \hline \end{array}$
