hypotenuse (h)=?
perpendicular (p)=3
base(b)=2
using pythagoras theorem
h²=p²+b²
h²=3²+2²
h²=9+4
h²=13
h=√13
b²=h²-p²
b²=12²-10²
b²=144-100
b=√44
b=2√11
Answer:
26
Step-by-step explanation:
Simply set up a proportion. 1/3 = x/48. Cross multiply afterwards. 48 = 3x. Solve the equation. x = 16. By using proportions which is another form of a ratio you can easily find out that there are 16 adults at the school. Hope this helps :))
3/4 of X = 15
Multiplying out gives;
3X = 4x15
3X= 60
X = 20
Therefore, 4/5 of 20
Putting X = 20 we have;
4/5 x 20 = 16
so the answer is 16
