Percent formula : is/of = %/100
is = 12
of = 60
% = x
now we sub
12/60 = x/100
cross multiply
(60)(x) = (12)(100)
60x = 1200
x = 1200/60
x = 20
check..
0.20(60) = 12
12 = 12 (correct)
so 20% of 60 is 12
Answer:
17.6625 m³
Step-by-step explanation:
The formula for volume of a cylinder is V = π * r² * h
Now we must rewrite the formula replacing variables. Also we will use 3.14 for pi
V = 3.14 * 1.5² * 2.5
Solve like usual. Keep in mind the order of operations
This gets you 17.6625
Round if needed.
Consider this option (2 ways for this):
1. Probability=1-[probability_all_boys].
for [probability_all_boys]=1/[all_possible_combinations];
for [all_combinations]=2³=8. It means that
Probability=1-(1/8)=7/8=0.875.
2. Probability=[needed_cases]\[all_possible_cases];
all possible combinations are:
bbb;ggg;bgg;bgb;bbg;gbg;gbb;ggb; - (where 'g' - girl, 'b' - boy) total 8.
needed cases: ggg;bgg;bgb;bbg;gbg;gbb;ggb, - total 7.
Probability=7/8=0.875
N.linear! hope this helps!
