In order to safely clear a hurdle, a track runner must jump the hurdles with an angle of 30°. Find the height of the hurdle and the horizontal distance traveled if the runner covers a distance of 5 feet
The hurdle and runner form a right triangle (see attached picture) such that
sin(30°) = h / (5 ft)
and
cos(30°) = x / (5 ft)
where h is the height of the hurdle and x is the horizontal distance from where the runner jumps to the hurdle. So
h = (5 ft) sin(30°) = 5/2 ft = 2.5 ft
x = (5 ft) cos(30°) = (5√3)/2 ft ≈ 4.33 ft
Prove the theorem: In a plane, if a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other. Given the facts RS ⊥ CD and AB || CD, drag and drop each reason next to the appropriate statement in order to prove the statement RS ⊥ AB.
Answer:
The theorem requiring proof;
A transversal perpendicular to one of two parallel lines is also perpendicular to the other parallel line
The two column proof is as follows
Statement [tex]{}[/tex] Reason
RS ⊥ CD [tex]{}[/tex] Given
AB ║ CD [tex]{}[/tex] Given
The Slope of AB = The slope of CD [tex]{}[/tex] definition of parallel lines

Step-by-step explanation:
5% of x is =8
5/100 * X= 8
x=8*100/5=800/5=160
12% of x =5
x=41.666 approximately
8% of x=12
x=12*100/8=1200/8=150
5% of x= 12

Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
-x+5y=-7
-3x +14y=-18
Answer:
One solution:(-8,-3)
Step-by-step explanation:
x = 5y + 7
Plug this in for variable x in equation [2]
[2] -3•(5y+7) + 14y = -18
[2] - y = 3
Solve equation [2] for the variable y
[2] y = - 3
By now we know this much :
x = 5y+7
y = -3
Use the y value to solve for x
x = 5(-3)+7 = -8
Solution :
{x,y} = {-8,-3}

A telephone poll asked people whether they like playing golf. Of the 100 people polled,20 like playing golf. What percentage of the people like playing golf?
Given:
Of the 100 people polled, 20 like playing golf.
To find:
The percentage of the people who like playing golf.
Solution:
In the poll,
Total number people = 100
Who like playing golf = 20
Now, percentage of the people who like playing golf is
[tex]Required \%=\dfrac{\text{Number of people who like playing golf}}{\text{Total number people in poll}}\times 100[/tex]
[tex]Required \%=\dfrac{20}{100}\times 100[/tex]
[tex]Required \%=20[/tex]
Therefore, 20% of the people like playing golf.
keith is an elevator operator in a big hotel. A(t)A(t)A, left parenthesis, t, right parenthesis models Keith's altitude (in meters relative to the ground) as a function of time (in minutes).Match each statement with the feature of the graph that most closely corresponds to it.
Answer:
Step-by-step explanation:
A relative maximum (or minimum) point is a point that is higher (or lower) than all of the points surrounding it.
This graph has a relative minimum point where A(t)=-12A(t)=−12A, left parenthesis, t, right parenthesis, equals, minus, 12, which means that Keith's lowest altitude was \textit{12}12start text, 12, end text meters below the ground.
A positive (or negative) interval is a domain interval over which the function values are all positive (or negative).
Since A(t)>0A(t)>0A, left parenthesis, t, right parenthesis, is greater than, 0 over the interval [6.5,10][6.5,10]open bracket, 6, point, 5, comma, 10, close bracket, this is a positive interval. This means that between the \textit{6.5}6.5start text, 6, point, 5, end text- and \textit{10}10start text, 10, end text-minute marks, Keith was above the ground.
An increasing (or decreasing) interval is a domain interval over which the function values increase (or decrease) as the input variable increases.
In this graph, the interval, 5, point, 5, comma, 8, close bracket is an increasing interval. This means that between the end text-minute marks, the elevator was going up.
Which relations are functions? Select all that apply.
Answer:
A and C
Step-by-step explanation:
B has a domain connected to many other ranges which makes a relationship but confuses the whole function making it incorrect.
For answer D, the x coordinates 1 and 3 both have two y coordinates. That again makes a relationship but confuses the function making that answer incorrect.
In answer A, no domain is repeated in any of the points making it a function.
In answer C, again no domains are paired with more than one range making it a function. That why A and C are the answers

Kelly is using a compass and straightedge to perform the Geometric construction below.
Which of the following best describes the figure Kelly is constructing?
Answer:
The answer is A
Step-by-step explanation:
The line is perpendicular to RS through S
There are several constructions that can be done with the straightedge and the compass.
The statement that describes the figure Kelly is constructing is: (c) a line parallel to RS through Q
From the figure, we have the following observations
Two arcs intersect on line RSAnother set of two arcs intersect on the same level as point Q.When a line is drawn from point Q through the intersection of these lines, the line would be parallel to line RS.
Hence. we can conclude that:
Kelly is constructing (c) a line parallel to RS through Q

1. This equation shows how the total number of appetizer recipes Carly knows depends on the number of weeks she attends culinary school. a = 2w. The variable w represents the number of weeks she has attended culinary school, and the variable a represents the total number of appetizer recipes she knows. After how many weeks of culinary school will Carly know a total of 8 appetizer recipes? *
Answer:
16 weeks
Step-by-step explanation:
Set up a proportion with the equation.
a = 2w
8
2 x 8= 16 then 16/1=16
so she was at school for 16 weeks.

What is the equation of this line?
A. y = 2x - 3
B. y = -1/2x - 3
C. y = -2x - 3
D. y = 1/2x - 3
Answer:
A. y = 2x - 3
Explaination:
It can't be negative because then the slope would be going downward from left to right, this line is going upwards. Also, the steepness of the slope proves it is a slope of 2 because a slope of 1/2 isn't very steep. You can also count 1 unit over and look how much the line changes to find the slope.
Answer:
A
Step-by-step explanation:
X intercept : (3/2 , 0)
Y intercept : (0 , -3)
Slope: m=2
The Collatz conjecture is one of the most famous unsolved mathematical problems, because it's so simple, you can explain it to a primary-school-aged kid, and they'll probably be intrigued enough to try and find the answer for themselves.
Hi, you've asked an incomplete question. However, I inferred you need a brief explanation about The Collatz conjecture.
Explanation:
Put simply, what the Collatz conjecture unsolved problem entails is that if any positive number is picked and it is:
An even number (eg 2, 4, 6,...), then if they are divided by 2, the new number gotten should undergo the same process (that is to be divided by 2), it is believed your calculation would finally end up at 1. For example, let's pick the number 6, (6÷2=4; repeating the process 4÷2=1)An odd number, then if they are multiplied by 3 and 1 is added to the result, it is believed that your calculation would finally end up at 1.In the 2008 election there were 28 blue states and 22 red states express the red and the blue states as fractions in the lowest terms of the total number of states and also as decimals.
