Identifying the Constant of Proportionality. ... The constant of proportionality is the ratio between two directly proportional quantities. In our tomato example, that ratio is $3.00/2, which equals $1.50. Two quantities are directly proportional when they increase and decrease at the same rate.
5,649 rounded to the nearest thousand is:
6,000 because 6 is larger than 5

Answer:
Xbox $544.00 sales tax: 38.08 after tax: 582.08
Airpods $125:00 sales tax: 8.75 after tax: 133.75
A= 50.27 because the formula is pi times radius squared
C= 24.13 because the formula is 2 times pi times radius
Step-by-step explanation:

Angle C must = [180 - 73 - 57 ] = [180 - 130] = 50°
And using rhw Law if Sines, we have.....
AB/sin C = AC/sin B → 24/sin(50) = AC/sin(73) → AC = 24*sin(73)/sin(50) = about 29.96 in
