Answer:
The table represents a proportional relationship
Step-by-step explanation:
Given
x ------ y
1 ------- 15
2 --------30
4 ---------60
5 -------- 75
Required
Determine if the table shows a proportional relationship
To check this, we make use of the following formula;
Where k is the proportionality constant
When x = 1, y = 15
When x = 2, y = 30
When x = 4, y = 60
When x = 5, y = 75
Since the value of k for all values of x and y is the same; i.e. 15
Then, the table represents a proportional relationship
Answer: 660.4
Step-by-step explanation:
If one inch is 25.4 millimeters then 26 inches would be 26 x 25.4 which is equal to 660.4
Given:
Amount deposited on birth = $10,000.
Interest rate = 5% compound quarterly.
To find:
The balance on the person's 18th birthday.
Solution:
The formula for amount is
where, P is principal, r is rate of interest, n is number of times interest compounded in an year and t is number of years.
Substitute P=10000, r=0.05, n=4, t=18 in the above formula.
Therefore, the balance on the person's 18th birthday is $24459.20.
It might be 4 and 8 because 4 is one-half of 8 and when you multiply them you get 32
