Answer:
Option D is correct.
VS = 20 units.
Step-by-step explanation:
The complete question is contained in the attached image to this answer.
From the image attached and the additional information about the triangles, it is evident that that triangle VSW is similar to triangle QSR.
Hence, we can write the ratio as
(VS/QS) = (VW/QR)
VS = 2a
QS = 2 × VS = 2 × 2a = 4a
VW = 2a - 2
QR = 3a + 6
(2a)/(4a) = (2a - 2)/(3a + 6)
Cross multiplying,
2a (3a + 6) = 4a (2a - 2)
3a + 6 = 2 (2a - 2)
3a + 6 = 4a - 4
4a - 3a = 6 + 4
a = 10
VS = 2a = 20 units.

Answer: 450 rest 100
Step-by-step explanation:
So, we need to calculate this division 100.000/222 and get the rest.
Well, 222 enters in 1000 by 4 times.
222 times 4 is 888
So, 100.000/222 = 4
888-
We subtract 888 from 1000.
That will be 112
100.000/222 = 4
888
112
Now, get the next 0 down next to 112
100.000/222 = 4
888
1120
222 get in 1120 by 5 times.
5 times 222 = 1110
divide 1120 by 1110
100.000/222 = 45
888
1120
1110
That will be 10
100.000/222 = 45
888
1120
==10
Get the next zero down
100.000/222 = 45
888
1120
==100
222 gets in 100 by 0 times.
100.000/222 = 450
888
1120
==100
0
100 subtracted by 0 is 100
100.000/222 = 450
888
1120
==100
0
100
The rest is 100 and the result is 450
Now, you can do the verification:
222 time 450 is 99,900.
If you add the rest to 99,900 it will be 100.000. So the result is good
