Step-by-step explanation:
a)
8÷2=4
12÷3=4
27÷9=3
•it does'nt always take the same amount of time to serve each customer .
•10×3=30
b)
according to the question
2=18 point
4=36 point
8=72 point
18=9×2
36=9×4
72=9×8
so 1dollar =9point
•each dollar spent appears to earn the same number of point
•because 81=9×9, it costs 9 dollar
Density = mass/volume
Plug in your Provided Values
v=volume
18g/cm^3 = 4.5g/v. Multiple both sides by v
v(18g/cm^3) = 4.5g Divide both sides by 18g/cm^3.
v = 4.5g/(18g/cm^3) Your grams cancel out leaving 4.5/18 cm^3 as your volume which is also. .25 cm^3.
Hope this helps!
Good luck man ill give u a quick one -5865.25
The answer would be ~30~ because 2*2^3 = 2^4= 16 then 3*6=18 then 16+18-4=30
Hope this helps
