El área de un rectángulo es 600 cm2 . Calcula las dimensiones del rectángulo sabiendo que su perímetro es 100 metros.
Answer:
Step-by-step explanation:
The area of a rectangle is 600 cm2. Calculate the dimensions of the rectangle knowing that its perimeter is 100 meters.
The formula for the area of a triangle =
Length × Width = 600 cm²
LW = 600
W = 600/L
Perimeter of a rectangle = 2L + 2W = 100m
2L + 2W = 100
we substitute
2L + 2(600/L ) = 100
2L + 1200/L = 100
Multiple all through by L
2L² + 1200 = 100L
2L² - 100L + 1200 = 0
We factorise
2L² - 60L - 40L + 1200= 0
Las dimensiones del rectángulo serían:
Longitud = 30m
Ancho = 20m
Halla el largo y el anchoDado que,
Área del rectángulo = 600[tex]m^2[/tex]
Sabemos,
Área del rectángulo = l × b
entonces,
l × b = 600[tex]m^2[/tex]
⇒ l = 600/b ...(i)
A continuación, tenemos,
Perímetro = 100m
Lo sabemos,
Perímetro del rectángulo = 2(l + b)
⇒ 100 = 2(l + b)
al poner (i), tenemos,
⇒ [tex]100/2 = (600/b + b)[/tex]
⇒ [tex](600 + b^2)/b = 50[/tex]
al resolver esto, obtenemos;
[tex]b^2 + 600 = 50b[/tex]
⇒ [tex]b^2 - 50b + 600 = 0[/tex]
⇒ [tex]b^2 - 30b - 20b + 600= 0[/tex]
⇒ [tex]b(b - 30) - 20(b - 30) = 0[/tex]
⇒ [tex](b - 20) (b - 30)[/tex]
∵ [tex]b = 20 m, b = 30m[/tex]
poniendo el valor de b, podemos encontrar:
[tex]l = 600/20[/tex]
∵ [tex]l = 30 m[/tex]
∵ Longitud = 30m
Ancho = 20m

Answer:
x = 12 cm
Step-by-step explanation:
Based on the tangent and secant theorem,
8² = 4(4 + x)
Solve for x
64 = 16 + 4x
Subtract 16 from both sides
64 - 16 = 4x
48 = 4x
Divide both sides by 4
48/4 = 4x/4
12 = x
x = 12

Which equation below represents a line with a slope of - 2/3 that passes through the point (-4.5 , 10)?
A. y = - 2/3 x + 10
B. y = - 2/3 x +2.7
C. y = - 2/3 x + 7
D. y = - 2/3 x + 13
pls explain the answer if possible ^^
Answer:
Option C
Step-by-step explanation:
If a line passes through a point, then that point is called a solution to the line's equation. Substituting the x and y values of that solution into the equation will give a true statement. So, to find out which option is correct, we can substitute the x and y values of (-4.5, 10) into each equation and see if the result is a true statement.
Let's try this with option C. To make things easier, convert -4.5 into decimal form: [tex]-4\frac{1}{2}[/tex]. Substitute [tex]-4\frac{1}{2}[/tex] for x and 10 for y in the equation, then solve:
[tex]y = -\frac{2}{3} x+7\\\\10 = -\frac{2}{3} (-4\frac{1}{2} )+7\\10 = -\frac{2}{3} (-\frac{9}{2})+7\\10 = 3+7\\10 = 10[/tex]
10 does equal 10, so this is a true statement. Option C is the right answer.

Answer:
(x, y) = (7, 2 2/3)
Step-by-step explanation:
We can multiply the first equation by 2/5 to get ...
8x -6y = 40
The second equation gives an expression for 6y that we can substitute.
8x -(3x -5) = 40
5x +5 = 40 . . . . . eliminate parentheses
x +1 = 8 . . . . . . . .divide by 5
x = 7 . . . . . . . . . .subtract 1
Using the second equation, we find ...
3(7) -5 = 6y
y = 16/6 = 2 2/3
The coordinates of the point of intersection are (x, y) = (7, 2 2/3).

Let f(x)=x^2+2 and g(x)=1-3x Find each function value. f(g(-4))
Answer:
171
Step-by-step explanation:
First you plug -4 into the g(x) equation
g(-4)= 1-3(-4)
Use pemdas
g(-4)= 1+12
g(-4)= 13
Next you plug 13 into the f(x) equation
f(13)= 13^2 + 2
First you do 13^2=169
Add 2 and you get 171
Identify a transformation of the function f(x) = (x) by observing the equation of the function g(x) = (x)+56.

Answer:
-Entire triangle region : 120 sq.cm
-Area of semi circle : 100.53 sq.cm
-Entire composite figure : 220.53 sq.cm
Step-by-step explanation:
Area of triangle = ½ × base × height
= ½ × (8+8) × 15
=½ × 16 × 15
= 120 sq.cm
[tex]area \: of \: semi \: circle = \frac{1}{2} \pi {r}^{2} \\ = \frac{1}{2} \times \pi \times {8}^{2} \\ = \frac{1}{2} \times \pi \times 64 \\ = 32\pi[/tex]
=100.530.......
=100.53 sq.cm (rounded to 2 decimal place)
Area of entire figure = 120 + 100.5353
= 220.53 sq.cm
Hope I could help:))
Evaluate f(x) = 2|x – 5| for f(–5) and f(0).
f(–5) = –20, f(0) = –2
f(–5) = 10, f(0) = 0
f(–5) = 20, f(0) = 10
f(–5) = 12, f(0) = 5
Answer:
f(–5) = 20, f(0) = 10
Step-by-step explanation:
f(-5):
f(-5) = 2|-5 -5|
f(-5) = 2|-10|
f(-5) = 2(10)
f(-5) = 20
f(0):
f(0) = 2|0 - 5|
f(0) = 2|-5|
f(0) = 2(5)
f(0) = 10

Answer:
y = -1/4x + 2
Step-by-step explanation:
Pick two points on the graph. Points (-4, 3) and (4, 1).
[tex]\frac{x_{2} - x_{1} }{y_{2} - y_{1} }[/tex]
[tex]\frac{3-1}{-4-4}[/tex]
= [tex]-\frac{1}{4}[/tex]
Slope is [tex]-\frac{1}{4}[/tex].
The y-intercept is the point where the line intersects the y-axis. In this case, it's (0, 2). So +2.
y = -1/4x + 2
