Nina has 465 pennies in a jar. Daryl has 348 pennies in a jar. How many pennies do they have in all?

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

Answer:

The mass of A is 4000g.

Step-by-step explanation:

First, divide 28 by 40. Then square root this to get the scale factor between them. (5 over 6). Mass is like volume in this case, so we need to cube 5/6 and then multiply that by 6912 to get the mass of A.

28÷40.32= 25/36

√25/36 =5/6

5/6³ x 6912= 4000g
