<span>A graph is shown. The values on the x axis are 0, 2, 4, 6, 8, 10. The values on the y axis are 0, 10, 20, 30, 40, and 50. Points are shown on ordered pairs 0, 0 and 2, 10 and 4, 20 and 6, 30 and 8, 40. These points are connected by a line. The label on the x axis is Number of Hours. The title on the y axis is Total Amount in dollars.</span>

To find 4 out of 10 shaded, we can turn this into a decimal by simply dividing 4 by 10. A rule that many people use is that for every 0 in a 1 with a number of 0’s after it (note that it cannot contain any other numbers), you move the decimal place one to the left. For this, we have 4=4.0 as the decimal is always to the right of the integer. Next, we move the decimal one spot to the left, making our new decimal (and the final answer) 0.40. Unfortunately, however, this is not one of the answers that are possible - I would suggest making sure that 4 out of 10 are indeed shaded (are there 10 out of 10 shaded on the side?) and asking your teacher why 0.4 is not one of the answers.

50+0.03x
Step-by-step explanation:
All you need to do is look at the numbers given in the word problem and convert them to algebraic terms.
The formula for a finite geometric series is:
a₁ is the first term of the geometric series. From the given series we can see that the first term of the series is 16.
r is the common ratio of the series. r can be found by dividing a term by its previous term. so r for the given series will be:
r = 24/16 = 3/2
n is the number of terms in the series. We can use the general formula of a Geometric Series to find the number of terms in the given series:
We want to find at which number in the series is 81 located. Using the values, we get:
This means, there are 5 terms in the given series.
Using the values in the formula, we get:
This means, the sum of given geometric series is 211.
