Answer:
The proportional table in the attached figure
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line <u><em>and the line passes through the origin</em></u>
<em>Verify each table</em>
Find the value of the constant of proportionality k for each ordered pair of a table.
If all the values of k are the same, then the table represent a proportional relationship between x and y
Table 1
For x=1, y=2 ---->
For x=2, y=4 ---->
For x=3, y=8 ---->
The values of k are not equal
so
This table not represent a proportional relationship between x and y
Table 2
For x=0, y=4
The line not passes through the origin
so
This table not represent a proportional relationship between x and y
Table 3
For x=0, y=0 ----> is OK the line passes though the origin
For x=1, y=1 ---->
For x=2, y=4 ---->
The values of k are not equal
so
This table not represent a proportional relationship between x and y
Table 4
For x=1, y=4 ---->
For x=2, y=8 ---->
For x=3, y=12 ---->
The values of k are the same
so
This table represent a proportional relationship between x and y
Answer: $ 618
Step-by-step explanation:
Money borrowed = $1,854
Total months taken to repay = 18 (Number of installments)
Money paid per month =
Now , money paid in 1 year = 12 x $ 103 =$ 1236 [1 year = 12 months ]
After a year , Haley still owe = $1,854 - $ 1236= $ 618
Hence, Haley still owe her parents $618 after a year .
Answer:
25%
Step-by-step explanation:
George is 33% (
%) richer than Pete. Let Pete's percentage of wealth be 100%.
Thus George percentage of wealth = 100% + %
= %
= 133%
Pete's percent poorer than George can be determined by;
= ÷
× 100
= ×
×100
= 0.25 × 100
= 25%
Pete is 25% poorer than George.
