Electricity

for the circuit of figure, find the following quantities.
i can't show you the figure because i can't copy it from a PDF. i will just type it to show you the figure for you guys.

A single cell battery (which is 130 v) is connected to:
R1: 3k ohm
R2: 4k ohm
R3: 1k ohm, P=100 mW
R4: R (R is unknown)

find the following quantities:
a. The circuit current.
b. The total resistance of the circuit.
c. The value of the unknown resistance, R.
d. The voltage drop across all resistors in the circuit.
e. The power dissipated by all resistors.
