Answer:
C: 12.5
Step-by-step explanation:
The sides x and 11 could be defined as the Adjacent angle and the Hypotenuse. This means that we will use the cos function to solve this.
First we can set up our equation
Next we can solve for x by multiplying by x and dividing by
The average speed of Marcella in feet per seconds is 9.5 feet per second.
<h3>How are time taken for travel, distance traveled, and the average speed are related?</h3>We have this below shown relation between them
For the given case, we have:
The equation represents the line of best fit for the distance (in feet) that Marcella traveled over time (in seconds)
The line of best fit can be taken as approximately telling about the data points ( y = distance traveled in feet, and x = time spent )
Let the initial time be 'x' with initial distance traveled 'y', then the time after one second will be (x+1), and the distance traveled be
The value of y and are calculated as:
Thus, the average speed is calculated at time 'x' as:
We could've also used the fact that in the relation of y to x as , 'm' denotes the rate of y as x changes.
Thus, the average speed of Marcella in feet per seconds is 9.5 feet per second.

Answer:
Mr.Smith paid $29.4.
Step-by-step explanation:
Mr.Smith paid $24.5 plus additional 20% of $24.5, and to figure out the total amount that he paid, we need to know what is 20% of $24.50.
20% of $24.50 is:
.
Mr.Smith paid additional $4.9; therefore, the total amount he paid was
$24.5 + $4.9 = $29.4.
Mr. smith paid $29.4.
