Answer: 6
Step-by-step explanation:
Percent formula : is/of = %/100
18 is what percent of 20...
is = 18
of = 20
% = x
sub and solve
18/20 = x/100
cross multiply
(20)(x) = (100)(18)
20x = 1800
x = 1800/20
x = 90 <=== so 18 is 90% of 20
38 feet
In the first example the tree was 30 feet but the shadow was 10 feet taller due to the angle of the sun. Assume a 38 foot tree if right there with the same angle of the sun on it, then the shadow will also be 10 feet taller , 48 feet.
The answers are 9.8 and 10/3
