In 1979, the price of electricity was $0.05 per kilowatt-hour. The price of electricity has increased at a rate of approximately

2.05% annually. If t is the number of years after 1979, create the equation that can be used to determine how many years it will take for the price per kilowatt-hour to reach $0.10. Fill in the values of a, b, and c for this situation. Do not include dollar signs in the response.

The equation would be established as 0.10 = 0.05(1 + 0.0205) ^ t and the calculation indicates that it will take approximately 34.16 years. Here, 0.10 is the target value, 0.05 represents the initial amount, and 0.0205 corresponds to the annual percentage increase of 2.05%, expressed in decimal form. To simplify, we first combine the terms inside the parentheses and then divide both sides by 0.05.

How much profit was generated by the sales of gold label and black label combined?
lawyer [12517]
The profit produced by combining sales of gold label and black label equals the total of their individual profits. From the table \begin{array}{ccc}&\text{Number of bottles sold}&\text{Average profit (per bottle)}\\\text{Gold label}&1,000&\$2.75\end{array} you find the gold label's profit 1,000\cdot \$2.75=\$2,750. and similarly from another table \begin{array}{ccc}&\text{Number of bottles sold}&\text{Average profit (per bottle)}\\\text{Black label}&2,000&\$1.50\end{array} find the black label's profit 2,000\cdot \$1.50=\$3,000.. Adding these yields \$2,750+\$3,000=\$5,750.. Thus, option 5 is the correct choice.

A board 120 inches long is divided into 2 sections. If the ratio of the 2 sections is 3:5, what are the lengths of the sections?
Leona [12618]

Answer: D. 45 inches, 75 inches

Step-by-step explanation:

To resolve this inquiry, we first need to divide the board's total length by the number of segments forming the two sections.

Given the ratio of 3:5, one section consists of 3 segments and the other of 5, making a total of 8 segments.

120 divided by 8 equals 15 inches for each segment.

Next, we multiply the length of each segment by how many segments each section has (3 and 5).

15 times 3 equals 45 inches.

15 times 5 equals 75 inches.
