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.

Mr dambek had $90 to spend at the bulls game he spent 31/45 on his ticket the. He spent 3/7 of his remaining money at the conces

slavikrds [6]

Answer:

He does not have enough money to buy the hat.

Step-by-step explanation:

First find out how much he spent on the ticket:

$90 \times {31 \over 45}=2 \times 31=62$

He spent $62 on the ticket, so he has $90 - $62 = $28 remaining. Now find out how much of that he spent at the concession stand:

$28 \times {3 \over 7}=4 \times 3=12$

He spent $12 at the concession stand, so he has $28 - $12 = $16 remaining. He does not have enough to buy the $18 hat.
