Ok so what we have to do is 4+7+9=c
4+7=11
11+9=20
c=20
your answer is 20
Scale : 1 cm = 2.5 ft
1 cm = 2.5 ft
0.5 cm = 2.5 x 0.5 = 1.25 ft
Circumference = πD = π(1.25) = 3.93 ft
Answer: 3.93 ft
Each pair of numbers gives a value then another value that is 1/2 of the first. So the answer would be
6 = 3
Set up a x/100 = (14-48)/48 = -34/48 Multiply the cross 48x = -3400 x = 70.8333 so around -70.83% change
it is 21 :)))))))))))))))
