At 5 seconds, an object's velocity is 9 meters per second. At 8 seconds, the object's velocity is 25 meters per second. Assuming a constant acceleration, what is the acceleration in meters per second per second of the object? (If necessary, round to the nearest hundredth.)
Answers
A = (∆v)/(∆t)
A = (25-9)/(8-5)
A = 16/3
A = 21.33 (rounded to the nearest hundredth)

Since there are 48 paintings being donated by 12 collectors, then we can say that each collector will donate 4 paintings.
This means that Sergio will have 4 less paintings then he had before, which was represented by . Thus, our expression is now
.
The number of paintings Sergio will have in his art collection after his donation is p - 4
Given:
Number of Sergio's paintings = p
Total number of paintings to donate = 48
Number of collectors to donate (including Sergio) = 12
Number of paintings donated by each collector = Total number of paintings to donate ÷ Number of collectors to donate
= 48 ÷ 12
= 4 paintings per collector
Therefore,
Number of paintings Sergio will have in his art collection after his donation = Number of Sergio's paintings - Number of paintings donated by each collector
= p - 4

Mean is a problem of addition and division.
What is a mean?
It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
We can consider the following set of numbers.
= 1, 2, 3, 4, 5
The mean of 1, 2, 3, 4, 5.
= (1 + 2 + 3 + 4 + 5) / 5
= 15/5
= 3
We see that,
While calculating the mean we add all the given values and divide by the number of values added.
Thus,
Mean is a problem of addition and division.

The numbers are consecutive, so the larger number is (Q + 1) .
Five times the smaller number is 5Q .
Three times the bigger number is 3(Q+1) = 3Q+3 .
The problem says that when you add all this up ... 5Q + (3Q+3) ... you get 579.
5Q + 3Q + 3 = 579
Clean up the left side:
8Q + 3 = 579
Subtract 3 from each side:
8Q = 576
Divide each side by 8 :
Q = 72
The smaller number is 72, and the larger number is 73.
