Answer:
Step-by-step explanation:
1. Perimeter: 8cm + 8cm + 3cm + 3cm = 22cm
Area: 8cm x 3cm = 24cm
2. Perimeter: 5m + 5m + 5m + 5m = 20m
Area: 5m x 5m = 25m
3. Perimeter: 4m + 4m + 18m + 18m = 44m
Area: 4m x 18m = 72m

Step-by-step explanation:
39.00 x .14 = 5.46
39.00 -5.46 = $33.54

Step-by-step explanation:
Answer: The required constant of proportionality is 10.
Step-by-step explanation: Given that y is directly proportional to x, and y = 150 when x = 15.
We are to find the constant of proportionality.
According to the given information, we can write
![y\propto x\\\\\Rightarrow y=kx~~~~~~~~~~~~~~~~[\textup{where k is the constsnt of propotionality}].](https://tex.z-dn.net/?f=y%5Cpropto%20x%5C%5C%5C%5C%5CRightarrow%20y%3Dkx~~~~~~~~~~~~~~~~%5B%5Ctextup%7Bwhere%20k%20is%20the%20constsnt%20of%20propotionality%7D%5D.)
When y = 150 and x = 15, we get from the above equation that

Thus, the required constant of proportionality is 10.
