Answer:
192,000 of the CDs will be of rock music
Step-by-step explanation:
In this question, we are tasked with calculating how many of the CD’s will be of rock music.
To calculate this, we proceed as follows;
We simply find 64% of the total planned production of 300,000
Hence, we have
64/100 * 300,000
= 64 * 3000 = 192,000
Convert the back splash dimensions to inches. Calculate the areas of the back splash and a tile. Then divide the total area of the back splash by the tile area to get the number of tiles required, which is 192 tiles.
To determine the number of tiles needed, we first need to convert the dimensions of the back splash from feet to inches since the size of the tiles is given in inches. So, the back splash is 2.5 feet tall equal to 30 inches (because 1 foot = 12 inches and 2.5x12 = 30) and it is 8 feet long which is 96 inches (because 1 foot = 12 inches and 8x12 = 96).
Next, we calculate the area of the back splash by multiplying the length by the height which is 2880 square inches (30 inches x 96 inches = 2880).
Then, we find the area of a tile by multiplying the length and the width of the tile: 2.5 inch x 6 inch which equals 15 square inches.
Finally, we divide the total area of the back splash by the tile area to get the number of tiles required. So, 2880 square inches / 15 square inches equals 192 tiles.

multiplying polynomials find the product (2a-1)(8a-5)
The product of (2a-1)(8a-5) is 16a² - 18a + 5.
To find the product of (2a-1)(8a-5), we can use the distributiveproperty. This means that we multiply each term in the first polynomial (2a-1) by each term in the second polynomial (8a-5) and then combine like terms.
Applying the distributive property, we have:
(2a-1)(8a-5) = 2a(8a) + 2a(-5) - 1(8a) - 1(-5)
Simplifying this expression, we get:
16a² - 10a - 8a + 5
Combining liketerms, we have:
16a² - 18a + 5
Therefore, the product of (2a-1)(8a-5) is 16a² - 18a + 5.
In this case, we multiplied each term of the first polynomial by each term of the second polynomial, resulting in four terms. Then, we combined like terms to simplify the expression. The final product is a quadratic polynomial with a leading coefficient of 16 and terms involving the variable 'a'.

The period of the secant function is 2π, the correct option is C.
The period of a function is the value at which the function repeats itself.
The secant function is
f(x) = sec x
The period of the secant function can be determined from its graph.
A graph of y = sec x is plotted and the period is determined.
The period of the secant function is 2π, the correct option is C.
