Answer:
a. 600 CDs
b. 700 CDs
Step-by-step explanation:
a. Let us assume the number of CDs sold during the month be x
Number of CDs sold = 12
Given Percentage = 2%
So, the equation be
2% of x = 12
x = 600
So, the number of CDs sold during the month is 600
b. Now the number of CDs sold during the next month be y
Number of CDs sold = 14
Given Percentage = 2%
2% of y = 14
y = 700
So, the number of CDs sold during the next month is 700
a) what is the value of the ratio m1/m2?
b) if m1 and m2 are combined into one object, what is its acceleration under the action of the force
Force is the product of mass and acceleration
(a) The ratio m1/m2
Force is calculated as:
For the first object, we have:
For the second object, we have:
The forces on both objects are equal.
So, we have:
Divide both sides by 3m2
Hence, the ratio m1/m2 is 1/3
(b) The acceleration when the masses are combined
In (a), we have:
Make m2 the subject
Recall that:
So, we have:
Substitute
Substitute --- because the force is the same
Cancel out m1
Divide both sides by 4
Hence, the acceleration is 3/4
