What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.
a. 16 feet by 16 feet:
The width of the room on the scale drawing will be 16/1.5 = 10.67 inches, and the length will also be 10.67 inches. Since both dimensions are greater than the width and length of the paper, the scale drawing will not fit on one piece of paper.
Answer: No.
b. 10 feet by 15 feet:
The width of the room on the scale drawing will be 10/1.5 = 6.67 inches, and the length will be 15/1.5 = 10 inches. The length dimension of the scale drawing fits on the paper, Therefore, the scale drawing will fit on one piece of paper.
Answer: Yes.
c. 15 feet by 20 feet:
The width of the room on the scale drawing will be 15/1.5 = 10 inches, and the length will be 20/1.5 = 13.33 inches. Both dimensions are greater than the width and length of the paper, so the scale drawing will not fit on one piece of paper.
Answer: Not.
d. 12 feet by 16 feet:
The width of the room on the scale drawing will be 12/1.5 = 8 inches, and the length will be 16/1.5 = 10.67 inches. Both dimensions are less than the width and length of the paper, so the scale drawing will fit on one piece of paper.
Answer: Yes.

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].

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
Work out the value of angle x.

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
