Answer:
Mass of A = 5760 grams
Step-by-step explanation:
Surface area is given, so we can set-up a similarity equation to solve for k, proportionality constant. Here, we will relate both of them through k^2, because they are 2 dimensional (area). Thus
Surface Area of A = k^2 * Surface Area of B
28 = k^2 * 40.32
k^2 = 28/40.32
k^2 = 25/36
k = Sqrt (25/36)
k = 5/6
Now, we want to find mass (1 dimensional quantity), thus we can say:
Mass of A = k * Mass of B
Mass of A = (5/6) * (6912)
Mass of A = 5760 grams
The correct answer is 16/81. Hope this helps.
5 because their are 5 burgers
Answer:
5a. 14w
6a. 8b2 - 5b + (-4)
7a. (-3x2) +9x - 4
8a. 3 + 0b
9a. 19 + 6a
Step-by-step explanation: it’s basically imagine that x is :) and y is :( you cant add :( to :) because they are different also the symbols in front of them show if it’s negative or positive
