Step-by-step explanation:
Circumference of a circle is 2piR
C=2piR and R=10
C=2(3.14)(10)
So the circumference is 62.8 cm
10% of all the cars is 20 limos.
20 * 10 = 200 cars total.
limos + vans + sedans = total cars
200 cars total - 20 limos - 60 vans = x sedans
x = 120 sedans
1 meter = 39.370 inches.....so 5 meters = (5)(39.370) = 196.85 inches
You can make an equation to solve this, but establishing knowns, unknowns, and relationships.
# in spring wash = x
# in summer = x + 14
Total Washes = 96
we know:
total = summer + spring
96 = (x) + (x + 14)
96 = 2x + 14
82 = 2x
"x" = 41
Answer: 629.51
Step-by-step explanation: 30% of 864.72 is 259.416
864.72 - 259.416 = 605.304 4% of 605.3 = 24.212 605.3 + 24.21 = 629.51
