This question reveals an intriguing pattern.
The rule or pattern to follow here is:
For the left side of the number compared to its predecessor: (First digit x Third digit + 1)
For the right side: (Second digit x Fourth digit -1)
For instance, consider 6447. Next, let's examine its previous number, 9876.
Now, 
and
that's how we arrived at 6447
Next, for the third number, 2527, let's look at its previous number, 6447
Now, 
and 
that's how we reached 2527
Following the same reasoning, the missing number should be 534.
This conclusion came from applying the rule of the pattern as:
and
Thus, we derived 534.
Answer:
The illustration provided shows the graph
Step-by-step explanation:
Let
x ------> number of times Emma cuts the grass
y ------> hours Emma spends babysitting
it is known that
------> represents the inequality of the scenario
The solution is the shaded region above the solid line where both x and y are positive
The equation for the solid line is represented as 
The slope of the line is negative 
The y-intercept is at the point 
(the y-value when x is zero)
The x-intercept is at 
(the x-value when y equals zero)
therefore

For this query, the time presented seems unclear to me. I understand that the rate of return is determined by total return over the investment. Assuming Matt received $400 as dividends without reinvesting them into additional shares, his total return across two years amounted to $500. Conversely, if the dividends were reinvested into the stock—something that typically happens with a 401(k) or IRA—his ROI would render a mere 6% due to only a $100 gain on a $1500 investment. In an actual market scenario, it’s likely that Matt would have experienced about a 5% return on a solid stock, while Bella would have had approximately 0.05% from a savings account.
I hope this was helpful!;)
Short Answer: Current speed = 3 miles per hour. Given details for downstream distance of 4.48 miles at time 0.32 hours and upstream distance of the same 4.48 miles taking 0.56 hours. Using the equation d = r*t, we equate distances for both directions leading to a function in terms of the current speed. With each correction to solve ultimately yields the current speed as 3 mph.
