Answer:
x=7.608696
Step-by-step explanation:
Simplify both sides of the equation.
262.5=10.5x+24x
262.5=(10.5x+24x)(Combine Like Terms)
262.5=34.5x
262.5=34.5x
Step 2: Flip the equation.
34.5x=262.5
Step 3: Divide both sides by 34.5.
34.5x
34.5
=
262.5
34.5
x=7.608696

Answer:
El perímetro del triángulo rectángulo es aproximadamente 29.627.
Step-by-step explanation:
Las coordendas de los vértices del triángulo rectángulo son 
, 
y 
. En primer lugar, determinamos las longitudes de los segmentos AB, BC y AC por el Teorema de Pitágoras:
![AB = \sqrt{(-8-1)^{2}+[4-(-2)]^{2}}](https://tex.z-dn.net/?f=AB%20%3D%20%5Csqrt%7B%28-8-1%29%5E%7B2%7D%2B%5B4-%28-2%29%5D%5E%7B2%7D%7D)
![BC = \sqrt{[5-(-8)]^{2}+(2-4)^{2}}](https://tex.z-dn.net/?f=BC%20%3D%20%5Csqrt%7B%5B5-%28-8%29%5D%5E%7B2%7D%2B%282-4%29%5E%7B2%7D%7D)
![AC =\sqrt{(5-1)^{2}+[2-(-2)]^{2}}](https://tex.z-dn.net/?f=AC%20%3D%5Csqrt%7B%285-1%29%5E%7B2%7D%2B%5B2-%28-2%29%5D%5E%7B2%7D%7D)
El perímetro del triángulo (
) es la suma de todos estos segmentos:
El perímetro del triángulo rectángulo es aproximadamente 29.627.
Answer:
Among the given samples the sample which constitute a biased sample is given by, the sample obtained by,
'Surveying randomly among seventh grade girls of a school to determine what theme the whole school would prefer for the dance.'
Step-by-step explanation:
Among the given samples the sample which constitute a biased sample is given by, the sample obtained by,
'Surveying randomly among seventh grade girls of a school to determine what theme the whole school would prefer for the dance.' since the choices of those seventh grade girls in the sample may not reflect those of the whole school.
