She has 24 friends.

Explanation

Suppose, the number of friends is $x$

She gave 3 pieces of gum each of her friends. So, the total number of gums given to $x$ numbers of friends will be: $3x$

She had total 77 pieces of gums and after giving to her friends, she has only 5 remaining. So, the equation will be......

$3x+5=77\\ \\ 3x=77-5= 72\\ \\ x= \frac{72}{3}= 24$

So, she has total 24 friends.

Answer: 18.75 lb.ft

Step-by-step explanation:

Given

Force required to stretch spring 8 in. is 18 lb

it can be written

$\Rightarrow F=kx\\\Rightarrow 18=k(8)\\\\\Rightarrow k=\dfrac{18}{8}=\dfrac{9}{2}\ lb/in.$

Work done in stretching from its natural length to 10 in.

$\Rightarrow W=\dfrac{1}{2}kx^2\\\\\Rightarrow W=0.5\times \dfrac{9}{2}\times (10)^2\\\\\Rightarrow W=225\ lb.in.\ or\\\Rightarrow W=18.75\ lb.ft$
