Average price, excluding taxes, for each CD is <u>10.20</u>.
Step-by-step explanation:
Given:
Cost of first 5 CDs,
Cost of each additional CD = 15.00
Now, cost of 10 additional CDs is the product of cost of one CD and total number of additional CDs. Therefore,
Cost of 10 additional CDs is,
Now, total CDs purchased by Jana are,
Total cost of the 15 CDs purchased is given as:
Now, average price, excluding taxes, for each CD is given as:
Therefore, the average price, excluding taxes, for each CD is 10.20.

Answer:
d-50
Step-by-step explanation:
Looking at the attached diagram, the only way to solve for this is the use of the trigonometric function. The trigonometric function to be used is the cosine function.
From the diagram, we are given
Hypotenuse = AB = 14
Adjacent = AC = 9
The measure of angle A to the nearest degree is calculated as:
cos θ = Adjacent / Hypothenuse
cos θ = 9/14
θ = cos -¹ (9/14) or arccos(9/14)
θ = 49.994799115°
To the nearest degree = 50°
Therefore,the measure of angle A to the nearest degree = 50°
