the music department of a department store sold 12 just CDs last month jazz sells during the month we have 2% of the music departments total sales suppose that the store sells 14 sets jazz CDs during the next month and the percent of the sales from the jazz CDs is still 2% what is the total number of the CDs that the store will sell

Answers

Answer 1
Answer:

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

Answer:

Step-by-step explanation:

Simplify x and y by rationalising the denominator of both

To rationalise the denominator multiply the numerator/ denominator by the conjugate of the denominator.

The conjugate of 2 + √(3) is 2 - √(3)

The conjugate of 2 - √(3) is 2 + √(3)

x = (1(2-√(3)) )/((2+√(3))(2-√(3)) ) = (2-√(3) )/(4-3) = 2 - √(3)

y = (1(2+√(3)) )/((2-√(3))(2+√(3)) ) = (2+√(3) )/(4-3) = 2 + √(3)

Thus

x + y = 2 - √(3) + 2 + √(3) = 4

A graph has age (weeks) on the x-axis, and height (inches) on the y-axis. Points are grouped closely together and increase slightly.Describe the relationship between the variables.
There is no relationship between the variables.
As the age increases, the height increases.
As the age increases, the height decreases.
As the height decreases, the age decreases.

Answers

Answer:

the correct answer is B because if you look at the graph you will see that both are increasing so the answer is as the age increases the height increases

If there is the same slope but different y-intercepts can there paths ever cross?

Answers

if the gradient is the same but there are different y intersects, the straight lines will never cross but they will be parallel.the answer is they will never cross
No, because lines that have same slopes are parallel and parallel lines never cross. So they will not cross. Hope this helps.
