Answer:
k=57
Step-by-step explanation:
-k+15=k-99(vertically opposite angles)
k=57
Opposite angles are equal
[tex]\\ \rm\longmapsto -k+15=k-99[/tex]
[tex]\\ \rm\longmapsto -k-k=-99-15[/tex]
[tex]\\ \rm\longmapsto -2k=-114[/tex]
[tex]\\ \rm\longmapsto 2k=114[/tex]
[tex]\\ \rm\longmapsto k=\dfrac{114}{2}[/tex]
[tex]\\ \rm\longmapsto k=57[/tex]

At a competition with 7 runners, medals are awarded for first, second, and
third places. Each of the 3 medals is different. How many ways are there to
award the medals?
Decide if this is a permutation or a combination, and find the number of ways
to award the medals.
Answers
Answer:
35 different combinations
Step-by-step explanation:
This would be a combination because the same person cannot get all three medals so permutation is not the correct way to calculate this. We use the formula C(n,r)=(nr)=n!(r!(n−r)!)=? where n is the number of total objects and r is the number of objects taken from the total.

Step-by-step explanation:
Complementary angles sum to 90° , then
5x + 7 + 8x - 21 = 90 , that is
13x - 14 = 90 ( add 14 to both sides )
13x = 104 ( divide both sides by 13 )
x = 8
Then the measure of the angles are
5x + 7 = 5(8) + 7 = 40 + 7 = 47°
8x - 21 = 8(8) - 21 = 64 - 21 = 43°
--------------------------------------------------------
let the angle be x then its complement is (90 - x) and
x = 2(90 - x) + 21
x = 180 - 2x + 21
x = 201 - 2x ( add 2x to both sides )
3x = 201 ( divide both sides by 3 )
x = 67
The measure of the angle is 67°

Set up a system of equations.

How to calculate the distance between two runners?? Ex) A finish 100m in 10.93 sec, and B finish in 10.49 sec, by how many meters did B won?? (Pls help me)
Answers
Answer:
The average speed of A is
100m ÷ 10. 93s = 9.14m/s
The average speed of B is
100m ÷ 10. 49s = 9. 53m/s
The average speed that B is faster than A is 9. 53 - 9. 14 = 0. 42m/s
The speed that B is faster than A is
0. 42m/s × 10. 49s = 4. 40m
So, B won by 4. 40m

find the smallest number that should be multiplied to 3993 to make it perfect cube
[tex]cube \: and \: cube \: root \: [/tex]
Answers
Answer:
First, let us prime factorise the given number
3993 = 3×11×11×11
Check for numbers in triplets. We find that only 11 is occuring as a triplet. Hence we must eliminate the three.
So if we divide 3993 by 3, we'll get a perfect cube, that is 1331 (11³)
So, the answer is 3

The first thing should always do is find a program that will show you what the graph looks like. Desmos is a free program that suits all graphing questions.
That will give you the answer (which I have labeled for you.)
First make x = 0
That gives you y = 0 + 4 = 4
The point is (0,4)
Now let y = 0
0 = -1/5 x + 4 Add 1/5x to both sides
1/5 x = 4 Now multiply by 5
x = 5*4
x = 20
The point is (20,0)
You need one more point just to confirm your work. I chose x = - 5
When you do the calculation it comes out to y = 5
The point is (-5,5) which is labeled.

At a school camp there is enough food for 150 students for 5 days.
a How long would the food last if there were only 100
students?
Answers
Answer: 7.5 days or 7 days (round down)
Step-by-step explanation:
STEP ONE: Find the total number of food in 5 days
150 students
5 days
150 × 5 = 750 unit of foods
In another word, there is enough food for 750 students in one day.
STEP TWO: Find the days this amount of food would last for 100 students
750 unit of food
100 students
750 ÷ 100 = 7.5 days
7.5 (round down) = 7 days
**Disclaimer** Rounding down to 7 days means that these food are enough for all 100 students for a whole day. If keeping 7.5 days, this would mean either the students would not be full, or there would only be half of the student body could get food. From my knowledge, I would round down. HOWEVER, this all depends on the rules that you would apply in mathematics.
Hope this helps!! :)

y=x^2-2x-5 vertex form
Answers
Hey there! I'm happy to help!
First, we'll want to find the vertex of this parabola.
Given the equation y=ax^2+bx+c, the formula for the x-coordinate of the vertex is always [tex]-\frac{b}{2a}[/tex].
In our equation here, our a is 1 and our b is -2.
[tex]-\frac{-2}{2}=\frac{2}{2}=1[/tex]
Now that we have our x-value of our vertex, we can plug it into our equation to find our y-coordinate.
y=1²-2(1)-5
y=1-2+5
y=-1+5
y=4
So, our vertex is at (1,4).
Vertex form is y=a(x-h)²+ k where (h,k) is our vertex. We know now that our vertex is (1,4) and we also know that our a is 1, so we can simply plug it in to this equation.
y=(x-1)²+4
