Answer:
252
Step-by-step explanation:
The order of the books isn't important, so we'll use combinations.
The number of ways to choose 5 books from 10 is:
₁₀C₅ = 10! / (5! (10 − 5)!)
₁₀C₅ = 10! / (5! 5!)
₁₀C₅ = 10×9×8×7×6 / (5×4×3×2×1)
₁₀C₅ = 252
Answer:
Solution given;
l=4.5ft
b=2ft
h=2ft
now
volume=l*b*h=4.5*2*2=18ft³
is a required volume.
Now
total surface area =2(lb+lh+bh)
=2(4.5*2+4.5*2+2*2)=44ft²
is a total surface area.
We can convert grams to kilograms by dividing by 1000.
3500÷1000=3.5kg
Now we subtract this from her original weight
65.5-3.5= 62kg
