Answer:
D
Step-by-step explanation:
1. Add the costs together 10.98+13.95+22.56=47.49
2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.
47.49/3=15.83
The option closest to our number is D so we round up.
$15.83->$20
Have a good day.
Well, it depends on the size of the ice cub and how much heat is being added. if its smaller and it has large amounts of heat being added it will melt fast, if its small and low amounts of heat are being added it will melt slower, if its a big cubs and large amounts of heat are being added it will melt slower than the small cub at the same temp but if its getting more heat than the small cub its should melt faster, ect. but in your case id say your right and bigger surface slower melt.

Answer:
$4.00
Step-by-step explanation:
Mark down it by 25% three times will be 75%, so when you multiply the two, it becomes 75%. do 16/4 to get the reduction for 25%,, and you get 12. Then dive it by for 2 more times to get $4
Standard form (which I assume is what they want you to turn these into) is y=mx+b.
12x-5y=20 is y=2.4x-4.
Subtract 12x from both sides, -5y=-12x+20.
Multiply both sides by -1, 5y=12x-20.
Divide both sides by 5, y=2.4x-4.
y=x+4 is already in standard form- I'm not quite sure what to do.
3x+y=3 is y=-3x+3.
Subtract 3x from both sides, y=-3x+3.
x=-y+3 is y=-x+3
Ad y to both sides, y+x=3.
Subtract x from both sides, y=-x+3.
