\bf \stackrel{total}{27}\qquad 4:5\qquad \cfrac{4}{5}\implies \cfrac{4\cdot \frac{27}{4+5}}{5\cdot \frac{27}{4+5}}\implies \cfrac{4\cdot 3}{5\cdot 3}\implies \cfrac{\stackrel{packed~lunch}{12}}{\stackrel{did~not~pack~lunch}{15}}

How to solve this problem
Slav-nsk [51]

Answer:

8.95

Step-by-step explanation:

here we are going to use pythagoras theorem

a² +b² =c²

the vertical can be taken as a and horizontal as b

4² +8²=c²

this is the same as

c²= 4²+ 8²

c²= 16+ 64

c²=80

to get rid of the square we shall put both sides under a root

\sqrt{c ^{2} }  =  \sqrt{80}

c = 8.95
