Answer:

3 30 page printers, 10 70 page printers

Step-by-step explanation:

x + y = 13

40x+70y = 820

Solving for y in first equation gives: y = 13 - x

Plug into second equation: 40x + 70(13 - x) = 820

40x + 910 - 70x = 820

-30 x = -90

x = 3

Plug into original equation: 3 + y = 13

y must = 10.

So, the company owns 3 thirty page presses, and 10 70 page presses,

In a parallel circuit, ET = 120 V, R = 30 Ω, and XL = 40 Ω. What is IR?
soldi70 [24.7K]

Answer:


Step-by-step explanation:

Given

ET = 120 V

, R = 30 Ω,

XL = 40 Ω.

To find = IR=?

as in circuit inductor and resistor are parallel so ET =EL = ER = 120V

IR = current through resistor = IR = ER/ R

                                                      = 120V /30Ω.

                                                       = 4 ampere.
