Answer: The constant proportionality is 5/4
Step-by-step explanation: The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Step-by-step explanation:
Translate the verbal statements into a system of linear equations: Fatima invested a total of $1000 in two simple-interest bank accounts. One account paid 5% annual interest; the other paid 6% annual interest. The total amount of interest she earned after 1 year was $56
Simple interest formula =
I = PRT
We are to find the Amount = Principal invested
For Account 1
I1 = P × 5% × 1
= 0.05P
Account 2
I2 = P × 6% × 1
= 0.06P
Therefore:
0.05P + 0.06P = $56
Answer:
$77,380
Step-by-step explanation:
If she gets a 6% raise next year she will make 106% of what she makes this year.
106% is 1.06 as a decimal. Multiply her salary by 1.06 to find out how much she will make next year...
$73,000(1.06) = $77,380
Answer:
Area = 10 1/9 meters squared
Step-by-step explanation:
mixed number to improper fraction:
4 2/3 meters = 14/3 meters
2 1/6 meters = 13/6 meters
Area = length times width:
Area = (14/3) x (13/6)
= 182/18
Simplify fraction:
182/18 = 91/9
improper fraction to mixed number:
91/9 = 10 1/9 meters
AREA = 10 1/9 meters
