En este problema, estamos hablando del autoretrato de Leonardo Davinci. Para la resolución de este problema, necesitamos usar el cuadrado mágico de forma tal que al colocar en cada casilla los números del 1 al 16 sin repetición, entonces los números de cada fila, columna y diagonal sumen 34. De esta manera, si se colocan los números así, el resultado obtenido es 34. En la figura de abajo se encuentra el cuadrado mágico resuelto:
Columna 1:
Columna 2:
Columna 3:
Columna 4:
Fila 1:
Fila 2:
Fila 3:
Fila 4:
Diagonal 1:
Diagonal 2:
Finalmente, esta pintura fue realizada en el año 1513, que son los números de las casillas en negro.
Answer:
Step-by-step explanation:
If we assume that the angle at A is 90 degrees.. which it does seem like it would be. then use that the sum of the angles around the inside of a right triagle is 180 . so you have
180 = 37 + 90 + x
53° = x
does that help?
Answer:
X=10
Step-by-step explanation:
Since the sign before the parentheses is a + , we can just remove the parentheses.
<span>5i + (-9 - i) = 5i - 9 - i = -<u>9 + 4i</u></span>
If order mattered, then there would be 6*5*4*3 = 30*12 = 360 different ways to form the committee. However, no single member outranks the other. Each member has equal ranking. So order does not matter.
Since order does not matter, we must consider all of the ways to arrange a single group of 4 people. That is 4! = 4*3*2*1 = 24 ways. We overcount by a factor of 24 when order doesn't matter which is why we divide the previous result (360) by 24 to get 360/24 = 15
Answer: 15
Note: you can use the combination formula n C r = (n!)/(r!*(n-r)!) with n = 6 and r = 4 to get the same answer
