B percent of something (x)
means: b/100 * x
ex: (2)
20% of 120 = 20/100*120 = 24
ex: (4)
18 = 40 % of x
means: 40*x/100 = 18
x=45
and so on
hope that helps

Answer:
false
Step-by-step explanation:
false
36 because 55 divided by 5 equals 11 and 11 x 2 = 22 and 35 ÷ 5 equals 7 and 7× 2 equals 14 and 14+22=36
bearing in mind that 1Kg ≈ 2.2lbs.
so, if a baby is say 2.2lbs, and then it doubles in weight, to 4.4lbs.
well, we know when the baby was 2.2lbs it was exactly 1Kg, but when it went up to 4.4lbs, is it 2Kgs? well, yes, 2Kgs = 2.2 + 2.2 or 2(2.2).
so, multiplying the lbs value by some factor, will retain the Kg:lbs ratio.
Answer:
1. x= 12.20
2. x= 8.94
3. x= 31.80
Step-by-step explanation:
1.
H =x , P = 7 and B = 10
using pythagoras theorem
H = 12.20
2.
H =21 , P = x and B = 19
using pythagoras theorem
P = 8.94
3.
H =x , P = 15.09 and B = 28
using pythagoras theorem
P = 31.80
