Jack, Alex and Amir jumped a total of 12.69 m in a long

jump competition.

Alex jumped exactly 200 cm further than Jack.

Amir jumped exactly 2,000 mm further than Alex.

What distance did they all jump?

Give your answers in metres.​

Answers

Answer:

Step-by-step explanation:

The distances they jumped were

x,y,z

y=x+2

z=x+2+2=x+4

x+y+z=12.69

x+x+2+x+4=12.69

3x+6=12.69

3x=6.69

x=2.23

So Jack jumped 2.23m, Alex jumped 4.23m, and Amir jumped 6.23m.

Ecuacion de la recta que pasa por el punto donde se cortan las rectas X+4Y=0 y X-3Y-7=0 y que tiene como pendiente -6

Answers

Answer:

La ecuación de la recta es [tex]y = -6\cdot x +23[/tex].

Step-by-step explanation:

Para construir la ecuación de la recta podemos utilizar un punto contenido en la recta y su pendiente. En primer punto, hallamos el punto con la resolución del siguiente sistema de ecuaciones lineales:

[tex]x+4\cdot y = 0[/tex] (1)

[tex]x-3\cdot y = 7[/tex] (2)

La solución del sistema de ecuaciones es [tex](x,y) = (4,-1)[/tex].

Por Geometría Analítica, sabemos que la Ecuación de la Recta en su forma explícita es:

[tex]y = m\cdot x + b[/tex] (3)

Donde:

[tex]x[/tex] - Variable independiente.

[tex]y[/tex] - Variable dependiente.

[tex]m[/tex] - Pendiente.

[tex]b[/tex] - Intercepto.

Si sabemos que [tex](x,y) = (4,-1)[/tex] y [tex]m = -6[/tex], entonces el intercepto de la recta es:

[tex]b = y-m\cdot x[/tex]

[tex]b = 23[/tex]

Ahora, la ecuación de la recta es [tex]y = -6\cdot x +23[/tex].

Step-by-step explanation:

If a large factory sells its new gadgets for $5 each, it can sell 1050 per month, and if
it sells the same gadgets for $9, it will sell 900 per month. To the nearest whole
number, how many gadgets could be sold per month, if the price was $12?

Answers

(5, 1050), (9, 900), (12, y)
For linear relation,
(y-1050)/(12-5) = (900-1050)/(9-5)
Solve for y,
y = 787.5

Round to the nearest whole number which will be 788

Hello There!

The problem states that the angles are complementary angles

Complementary angles are angles that have measures that add up to equal 90

So given one of the angles we can find the missing angle by subtracting the known angle from 90

90 - 81 = 9

so we can conclude that the measure of angle 2 is 9

Tony and Edwin each built a rectangular garden. Tony's garden is 4 feet longer and 5 feet wider than Edwin's garden. If the perimeter of Edwin's garden is 36 feet, what is the perimeter of Tony's garden?

Answers

Answer:

54 feet

Step-by-step explanation:

Perimeter of a rectangle = 2 × (length + breadth)

The perimeter of Edwin's garden is 36 feet :

36 = 2 x (length + breadth)

divide both sides by 2 to determine the sum of the length and breadth of Edwin's garden

36/2 = (length + breadth)

18 = (length + breadth)

Tony's garden is 4 feet longer and 5 feet wider than Edwin's garden

The dimensions of Tony's garden is :

(4 + l) + (5 + w) = 9 + l + w

Where :

l = length

w = width

The sum of the length and breadth of Tony's garden would be 9 feet more than that of Edwin

Sum of Edwin's garden = 9 + 18 = 27

Perimeter of Edwin's garden = 27 feet x 2 = 54 feet
