Associative property of addition represents this equation:
a + b = b + a
So, how would it be helpful with this given equation?
=> 48 + 82
=> Let's start with the ones place value.
(2 + 8) = 10, bring down 0, carry 1 then ( 4 + 8) = 12 + 1 = 13
So the answer is 130.
If we are going to do it vice versa, still expect that the same answer will occur.

Sean used candle molds, as shown, to make candles that were perfect cylinders and spheres:
BaLLatris [955]
We calculate for the volumes of each of the wax needed for the candles through the equations presented below.

For cylinder:
                             V = πr²h
where V is volume, r is radius and h is height.

Substituting the known values,
 
                           V = (3.14)(3 in)²(6 in)
                            V = 169.56 in³

For sphere:

                         V = 4πr³/3
Substituting the known values,
                        V = 4(3.14)(3 in)³ / 3 = 113.04 in³

The difference between the two volumes,

                         difference of volumes = 169.56 in³ - 113.04 in³
                         <em>difference of volumes = 56.52 in³</em>

Thus, the answer to this item is the last choice.

These triangles are NOT similar! Why not?<br> Use calculations AND words to explain.
zlopas [31]

Answer:

if ΔPQR ≈ ΔSTU =>

=> PQ/ST = PR/SU = QR/TU

9/7 = 12/8 = 15/10

9×8 = 7×12

72 = 84 (false)

=> ΔPQR ≠ ΔSTU
