Answer:
9 yards
Step-by-step explanation:
Since both pools are similar, therefore the ratio of their length and width would be equal. That is:
Length of the current swimming pool : length of the new swimming pool = width of the current swimming pool : width of the new swimming pool
Thus, we can set up a proportion as shown below:
Let the width of the new swimming pool be x.
40 : 24 = 15 : x
Cross multiply
Divide both sides by 40
The width of the new swimming that is smaller would be 9 yards.
Answer:
option (c) $18,032
Step-by-step explanation:
Data provided in the question;
Amount deposited at the end of each day = $1
Interest paid = 8% compounded daily = 0.08
Daily interest rate = = 0.000219
Duration = 20 years = 20 × 365 days = 7300 days
Now,
the Future value is given as:
Future value = Part payment ×
here, r is the interest rate
n is the duration
thus,
Future value = $1 ×
or
Future value = $18033.56 ≈ $18,032
Hence, the correct answer is option (c) $18,032
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
When y = 150 and x = 15, we get from the above equation that
Thus, the required constant of proportionality is 10.
