Answer:
-0.80, -3/4, 0, 5/3, 2.5
Step-by-step explanation:
Answer:
m = 5
Step-by-step explanation:
We are told that the two triangles are similar. Thus, each side of the larger triangle is the same multiple of the corresponding side in the smaller triangle.
Thus, 12 = k(7.2), where k is the constant of proportionality.
Solving this for k, we get
k = 12/7.2 = 1 2/3
Thus, side m is 1 2/3 times 3, or 5/3 times 3, or just 5.
m = 5
Number set:
18, 36, 900

This problem calls for calculating the unit cost in each case and then comparing the unit costs.
$1.79
---------- = $0.09/oz
20 oz
Noting that 1 lb = 16 oz,
$2.59
---------- = $0.14
18 oz
$1.79 for 20 oz is definitely the better buy (less expensive) when compared to $2.59 for 18 oz.
