How do we convert decimal numbers into binary numbers 2483?.
alisha [4.7K]

Answer:

Places in binary coding

1 - 2 - 4 - 8 - 16 - 32 - 64 - 128 - 256 - 512 - 1024 - 2048

2483 - 2048 = 435      there is 1 in the 2048 position

435 - 256 = 179    there is 1 in the 256 position

179 - 128 = 51        there is 1 in the 128 position

51 - 32 = 19         there is 1 in the 32 position

19 - 16 = 3           there is 1 in the 16 position

3 - 2 = 1            there is 1 in the 2 position

1 - 1 = 0             there is 1 in the 1 position

10011011 0011     would be the binary result

Check:

2048 + 0 + 0 + 256 + 128 + 0 + 32 + 16 + 0 + 0 + 2 + 1 = 2483

Help I Need Help Asap!
Leni [432]

Answer:

40° and 140° (with x = -10)

Step-by-step explanation:

Since the angles are supplementary (when added, equal 180°), you can add the two angles together to get (-18x)°. 180/-18 = -10 for x. Fill in -10 for x in both expressions. (-14 • -10)= 140° and (-4 • -10)- 40°. 140+40=180
