The next event requires each runner to jump 8 hurdles that are spaced 12.3 meters
apart. If there are 15 meters from the starting line to the first hurdle and 10.5 meters
from the last hurdle to the finish line, how long is the race? Show your work.
Answer:The race is 111.6
Step-by-step explanation:The race is 111.6 m long.
8 hurdles spaced 12.3 m apart means 7 spaces that are 12.3 m in length; 7*12.3 = 86.1
Add to this the distance to the first hurdle and the distance from the last hurdle:
86.1+15+10.5 = 111.6 m

What is the average rate of change of f over the interval -7 < or equal to x
Give an exact number
Answer:
[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
The average rate of change can be found by using the following formula
[tex]\frac{f(x_{2}) - f(x_{1}) }{x_{2} - x_{1}}[/tex]
Since the interval goes from -7 to 2, we should find the y-values that correspond to x=-7 and x=2.
By inspection of the graph, we can clearly see that when x is -7, y is -7 as well and when x is 2, y is 5.
Now that we know this, we can simply plug these values into the formula!
[tex]\frac{f(2) - f(-7) }{2 - (-7)} = \frac{5 - (-7)}{2 - (-7)} = \frac{5 +7}{2+7} = \frac{12}{9} = \frac{4}{3}[/tex]
Good luck!

Line BC is represented by 3x + 2y = 8. Line AD is represented by –3x – 2y = 6. What is the relationship of line BC to line AD? Explain how the sum of the equations demonstrates this relationship.
Answer:
2
Step-by-step explanation:
if you suntract the 2 you, 3x cancels 2y cancels, 8-6 is 2
Answer: Line BC is parallel to line AD. The system of equations has the sum 0 = 14. Since this is a false equation, the system has no solution, which means the lines will never intersect.

Find the x-value for point C such that AC and BC from a 2:3 ratio.
Given:
Point C divides AB such that AC:BC=2:3.
To find:
The x-value for point C.
Solution:
Section formula: If a point divide a line segment in m:n, then
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Form the given graph it is clear that the endpoints of the line segment AB are A(-3,5) and B(3,0).
Point C divides AB such that AC:BC=2:3. Using section formula, the coordinates of point C are
[tex]C=\left(\dfrac{2(3)+3(-3)}{2+3},\dfrac{2(0)+3(5)}{2+3}\right)[/tex]
[tex]C=\left(\dfrac{6-9}{5},\dfrac{0+15}{5}\right)[/tex]
[tex]C=\left(\dfrac{-3}{5},\dfrac{15}{5}\right)[/tex]
[tex]C=\left(-0.6,3\right)[/tex]
The x-value of C is -0.6.
Therefore, the correct option is B.
A plumber charges a one-time service fee of $20 in addition to his hourly rate of $25 per hour. If the plumber went to your house to work on your bathtub and toilet and the bill came to $282.50, how many hours did it take him to complete the job?
A- 25 + 20x = 282.50; x = 10.5 hours
B- 20 + 25x = 282.50; x = 10.5 hours
C- 20 + 25x = 282.50; x = 12.1 hours
D- 45x = 282.50; x = 6.3 hours
Answer: B
Step-by-step explanation:
The number of hours it took him to complete the job is; Choice B: 20 + 25x = 282.50; x = 10.5 hours
According to the question;
The one-time service fee of the plumber is; $20
The plumber's hourly rate is; $25 per hour.
The total bill after working on toilet and bathroom came to; $282.50
The expression which represents the plumber's charge is therefore;
20 + 25x = 282.50where, x = number of hours to complete the job.
Therefore, to find x;
25x = 282.50 - 2025x = 262.50x = 262.50/25x = 10.5 hours.
The total number of hours it took him to complete the job is; 10.5 hours.

Mark uses 19 gallons of gas while traveling 399
miles at a constant rate in his car. How many
miles is Mark able to travel on 9 gallons of gas?
Answer:
189
Step-by-step explanation:
If mark uses 19 gallons to travel 399 miles, that means he was able to travel 21 miles per gallon.
We get this by taking 399 divided by 19.
So if mark travels on 9 gallons of gas and goes 21 miles per gallon, he will have traveled 189 miles.
We get this by taking 21 times 9

Is it a right triangle?
Answer:
No, it is a obtuse triangle instead
Step-by-step explanation:
So, you use pythagorean and theorem which is a^2 + b^2 = c^2
So when you plugin in the numbers, it's 20^2__ 12^2 + 12^2
When you square them you get left with 400__144 + 144
Then, you add 144 + 144 = 288
But since 400 is > than 288, then it's an obtuse triangle.
Answer:
No
Step-by-step explanation:
It does not follow the Pythagorean Theorem, which states that the two shorter sides squared (squared BEFORE added together). 12 squared is 144, and 144 plus 144 equals 288. 20, which seems to be the hypotenuse, squared is 400. 288 does not equal 400.
