Solve y-12/25=3 1/5. What number is y? A. 3 1/5 B. 3 17/25 C. 3 7/25 D. 4 17/25

kicyunya [14]

Answer:

Option c) y= $3\frac{17}{25}$ is correct

The value of y is 3 $\frac{17}{25}$

Step-by-step explanation:

Given equation is

$y-\frac{12}{25}=3\frac{1}{5}$

To solve the given equation for y

$y-\frac{12}{25}=3\frac{1}{5}$

$y-\frac{12}{25}=\frac{16}{5}$ (converting mixed fraction to normal fraction )

$y-\frac{16}{5}=\frac{12}{25}$

$y-\frac{(16\times 5)+12}{25}$ (taking LCM 25 )

$=\frac{80+12}{25}$ (adding the terms )

$y=\frac{92}{25}$ (now convert fraction into mixed fraction )

Therefore y= $3\frac{17}{25}$

Option c) y= $3\frac{17}{25}$ is correct

The value of y is 3 $\frac{17}{25}$

PolarNik [594]

Step-by-step explanation:

working ;

(3x+2)^2

*Apply Perfect Square Formula : (a+b) =a^2+2ab+b^2

a = 3x,b = 2

(3x)^2 + 3x.2+2^2

finally Answer is:

= 9x^2 + 12x +4

Tienes un triángulo equilátero con lados de 10cm, lo divides en dos partes de manera horizontal tal que el área de ambos figuras

Tanya [424]

Answer:

x = 10/√2 ≈ 7.07

Step-by-step explanation:

Comenzaremos por dividir el triángulo en dos partes y definir H, como en la figura adjunta.

Aplicando el teorema de Tales, sabemos que:

$\dfrac{l/2}{H}=\dfrac{x/2}{h}\\\\\\\dfrac{l}{H}=\dfrac{x}{h}$

También sabemos que, dado que el tirángulo menor es la mitad que el triángulo mayor, la relación entre áreas es:

$\dfrac{A}{A_x}=\dfrac{lH/2}{xh/2}=\dfrac{lH}{xh}=2$

Dado que formamos dos triángulos rectángulos, podemos despejar el valor de H como:

$(l/2)^2+H^2=l^2\\\\H^2=l^2-(l/2)^2=10^2-5^2=100-25=75\\\\H^2=\sqrt{75}$

Podemos entonces despejar x de la siguiente manera:

$h=\dfrac{H}{l}\cdot x=\dfrac{lH}{2x}\\\\\\2x^2\dfrac{H}{l}=lH\\\\\\2x^2=l^2\\\\\\x=\dfrac{l}{\sqrt{2}}=\dfrac{10}{\sqrt{2}}\approx7.07$
