Answer:
HI=1/2*EF
17-3x=1/2*-9x+37
2(17-3x)=-9x+37
34-6x=-9x+37
-6x+9x=37-34
3x=3
x=3/3
x=1
now substitute the value of HI
17-3x
=17-3*1
=17-3
=14
Step-by-step explanation:
Note :HI=1/2*EF because the straight line joining the mid points of two sides of a triangle is parallel to the third side and equal to half of it.
<span> If two secants intersect from a point outside of the circle, then you can use formula:
26(26 + d) = 22(22 + 40)
676 + 26d = 22 * 62
26d = 1364 - 676
26d = 688
d = 688/26
d = 26.5 </span>← to the nearest tenth
Answer: Option (B) is the correct answer.
Step-by-step explanation:
A point at which three altitudes of a triangle meet is known as orthocenter.
Whereas when a circle is inscribed in a triangle and it touches all the sides of a triangle then the center of circle is known as incenter.
When all the three medians of a triangle intersect each other then the point is known as centroid.
Circumcenter is a point where perpendicular bisectors on each side of a triangle bisect and this point is equidistant from all the vertices.
Reflexive pretty much means something relating to itself. The reflexive property of equality simply states that a value is equal to itself. Further, this property states that for all real numbers, so your answer will be (A) x = x.
Answer: Su salario regular por hora es $12
Step-by-step explanation:
Hola, para resolver este problema debemos plantear una ecuación:
A el hombre le pagan doble el tiempo que trabaja por encima de las 40 horas, el trabajo 47, o lo que es equivalente = 40+7.
Las primeras 40 horas recibió su salario regular por hora (x) y las otras 7 recibió el doble (2x). LA suma de esos productos da un total de $648.
Matemáticamente hablando:
40 x+ 7 (2x) = 648
Resolviendo para x (salario regular por hora)
40x +14x =648
54x =648
x = 648/54
x = 12
