Answer:

C Yes, 75+ 2.5*60 = 225

Step-by-step explanation:

The charges for the electrician

1st hour = 75

Additional hours 60

We have 3 1/2 hours of labor

The first hour is 75 dollars

3 1/2 - 1 = 2 1/2

There will be 2 1/2 hours at the 60 dollar rate

75 + 60 * 2.5 =

75 + 150

225

What are the next geometric sequences? The calculator won’t seem to give right answers

dalvyx [7]

5. the numbers are being multiplied by 4 each time, so the geometric sequence would be

an= 1/2(4) ^(n-1)

6. the numbers are being multiplied by 1/4 each time, so the geometric sequence would be

an= 32(1/4)^(n-1)

an in the formula is what ever term in the sequence.
32 or 1/2 is the a which is the first term in the sequence.
4 or 1/4 is the r in the sequence because it is the common ratio so what the equation was multiplied by to get the next term.
(n-1) is because when you are using this equation to solve for whatever term (an) you must subtract the first number in the sequence to get an accurate number

an you can input whatever number when trying to solve.

The center on a target has a diameter of 5 inches. The whole target has a diameter of 25 inches. The center of the target takes

Komok [63]

4%

To find the percentage, first find the area of both circles. The area formula is $\pi r^{2}$ . After finding the area of the center of the target (19.625) and the area of the large target (490.625), set up a percent proportion to determine the percentage that the center takes up:

$\frac{is}{of} = \frac{percent}{100}$

$\frac{19.625}{490.625} = \frac{percent}{100}$

Cross multiplying and dividing by 490.625 will give a total of 4%.
