400×10=4000
400×2=800
50×10=500
50×2=100
2×10=20
2×2=4
4000+800+500+100+20+4=5,424
Check answer by multiplying 452 and 12
452×12=5,424

Answer:
88.16 units
Step-by-step explanation:
The line at the far left is also = x
For right triangles
Tan (angle ) = opposite leg / adjacent leg
for this triangle tan 10 = x / 500
rearrange to x = 500 tan 10° = 88.16 units

Let ratios be 3x and 5x respectively
Now,
3x+5x=4800
X=600
Then
No of men=3x=1800
No of women=5x=3000
2)soln
2275/65=35min
3)soln
3x+5x=480000
X=60000
3x=180000
5x=300000
