Step-by-step explanation:
let third angle be x
60° + 60° + x = 180° (Δ sum property)
x = 60°
so, this is a equilateral triangle (all Δ equal)
-----------------------------------------in equilateral triangle --> all sides are equal
so, therefore =>>
7x + 19 = 11x - 89
19 + 89 = 11x - 7x
108 = 4x
108 ÷ 4 = x
27 = x
x = 27-----------------------------------------so variable
1.) 7x + 19
= 7(27) + 19
= 189 + 19
= 208
2.) 11x - 89
= 11(27) - 89
= 297 - 89
= 208

Answer:
I. p = 7
II. 17 litres
Step-by-step explanation:
I. Determination of the value of p
Mean = 17.7
p =.?
Let the number of litre be L
Let the number of motorist be M
Mean = summation LM / summation M
Summation of LM = (16×11) + (17×10) + (18×p) + (19×4) + (20×8)
= 176 + 170 + 18p + 76 + 160
= 582 + 18p
summation M = 11 + 10 + P + 4 + 8
= 33 + p
Mean = summation LM / summation M
17.7 = 582 + 18p / 33 + p
Cross multiply
17.7(33 + p) = 582 + 18p
584.1 + 17.7p = 582 + 18p
Collect like terms
584.1 – 582 = 18p – 17.7p
2.1 = 0.3p
Divide both side by 0.3
p = 2.1 / 0.3
p = 7
II. Determination of the median number of litre.
Let the number of motorist be M (i.e the frequency)
summation M = 11 + 10 + P + 4 + 8
p = 7
summation M = 11 + 10 + 7 + 4 + 8
summation M = 40
The median is the middle term i.e
Median = (summation M / 2)ᵀʰ motorist
Median = (40 / 2)ᵀʰ motorist
Median = 20ᵀʰ motorist
Considering the table in the question above, the 20ᵀʰ motorist has 17 litres.
Therefore, the median number of litres is 17 litres.

Answer:
Step-by-step explanation:
Equation for line of slope -6 that passes through (0,-2):
y+2 = -6(x-0)
y = -6x - 2
Plug in (g,-8) and solve for g:
-8 = -6g - 2

What is a hyperbola?The hyperbola is the locus of a point such that the difference of distance from point P to two non-movable points. These two points are called foci of hyperbola.
An asymptote is a line that constantly reaches a given curve but does not touch at an infinite distance.
The function is given below.
f(x) = [5 - 5x²] / x²
The equation of the vertical asymptote will be at x = 0. And the equation of the horizontal asymptote is given as,
f(x) = [5 - 5x²] / x²
f(x) = [5(1 - x²)] / x²
f(x) / 5 = [1 - x²] / x²
The equation of the horizontal asymptote will be y = - 5.
The graph that represents the function f(x) = [5 - 5x²] / x² will be drawn below. Then the correct option is B.

Answer:
40% of 84 is 33.6
Step-by-step explanation:
No following options are listed, but I will solve for 40% of 84
First set these up into an equation
40/100 = x/84
Cross multiply
40 × 84 = 100 × x
3360 = 100x
Divide both sides by 100 to isolate the variable

los conjuntos numericos se relacionan entre si, los irracionales son caso aparte de los conjuntos numericos, cual sera la razon por lo que esto sucede?
Answer:
Los conjuntos numéricos que se relacionan entre sí son:
Naturales, enteros y racionales.
Los números naturales son aquellos números que se pueden escribir como sumas de 1.
Los números enteros son todos los números naturales, y agregamos el número cero y los números negativos.
Los números racionales son aquellos números que se escriben como cociente de dos números enteros. Acá también podés notar que:
7 = 7/1
entonces todo número entero se puede escribir como el cociente de dos enteros, lo que implica que el conjunto de los números racionales también engloba al conjunto de los enteros.
Entonces si N es el conjunto de los números naturales, Z es el conjunto de los números enteros, y Q es el conjunto de los números racionales, tenemos que:
N ⊂ Z ⊂ Q.
Ahora por otro lado, el conjunto de los números irracionales es aquel que no se puede escribir como cociente de dos números enteros. Con esto ya podemos concluir que no existe ningún elemento compartido entre ninguno de los conjuntos anteriores y este conjunto, y esto se debe a la definición de número irracional, como no se puede construir como el cociente de números enteros, entonces no hay forma de relacionarlo con ninguno de los otros conjuntos.

An artist mixes paint to make new colors.
She uses 13 cup of red paint and 13 cup of yellow paint to make a batch of orange paint.
If the artist has 2 cups of red paint available and 3 cups of yellow paint available,
how many batches of orange paint can she make?
Enter your answer in the box.
Answer:
The artist can make six batches of orange paint and it remains one cup of yellow paint
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Amount of red paint for one batch of orange paint = 1/3 of a cup
Amount of yellow paint for one batch of orange paint= 1/3 of a cup
Amount of red paint available = 2 cups
Amount of yellow paint available = 3 cups
2. How many batches of orange paint can she make?
2 cups of red paint = 6/3 = 6 batches of orange paint
3 cups of yellow paint = 9/3 = 6 batches and it remains one cup of yellow paint
The artist can make six batches of orange paint and it remains one cup of yellow paint

To find the area of a regular hexagon we use the formula
[tex]A = \frac{1}{2} ap[/tex]
a = apothem
p = perimeter
to find the peremeter we multiply the side length by the number of sides
which is 6
6x6=36 so the perimeter is 36
now we just plug it into the area of a hexagon formula
36x5.2=187.2
[tex]\frac{187}{2} =93.6[/tex]
so the area is 93.6 cm ³
