Responder:
Número total de bolas = 245/23
Explicación paso a paso:
Dado que:
Bolas blancas = 1/5
Bolas negras = 1/7
Bolas rojas = 7
Sea el número total de bolas = x
Bolas blancas = 1 / 5x
Bolas negras = 1 / 7x
Por tanto, total;
(x / 5 + x / 7 + 7) = x
((7x + 5x) / 35) +7 = x
(12x / 35) + 7 = x
7 = x - 12x / 35
7 = (35x - 12x) / 35
7 = 23 veces / 35
245 = 23x
x = 245/23
What is the volume of a cube with a side length of 2/5 cm? 0.4 cm
Answer:
m<C = 101°
m<E = 46°
Step-by-step explanation:
*This was the only problem I could figure out so I'm sorry*
C equals 101° b/c 1/2 a circle angle equals 180° which is the line. Angle F and Angle C are corresponding interior angles (same side angles) so if both of them together should equal 180. 180 - 79 (<F) = 101 (<C).
You do the same thing to find Angle E b/c it's corresponding interior angles to Angle D.
I hope you understand this explanation
