14. sometimes, you can have a 45-45-90 or 60-30-90 triangle (degrees)
sometimes true
15. always
16. never, paralellogram has 2 pairs of paralell sides, trapezoid has 1
17.always
18. sometimes
19. always
20. always
You have two choices: the easiest is to turn every fraction to its numerical equivalent:
Now, remember that negative numbers are ordered in the opposite way with respect to positive numbers (for example, 4 is larger than 2, but -4 is smaller than -2). So, the order is
Alternatively, you can convert all the fractions so that they have the same denominator. In this case, you will need the least common multiple of 10, 7, 4, 5 and 3, which is 420. Once you do so, you can easily order the fractions using numerators only.
Answer: For me it is the answer is the a I do not know if my answer will help you
Answer:
A 175/979 = M
Step-by-step explanation:
Si Matusalén vivió 979 años y Abraham vivió 175 esto quiere decir que abraham vivio menos años que Matusalén.
Por lo que la fracción va a tener que ser menor que 1 ya que al multiplicarla por la edad de Matusalén nos tiene que dar la de Abraham.
Tenemos que encontrar una fraccion que multiplicada por 979 nos de 175.
979 * X = 175
Tenemos que despejar la x y encontraremos el valor de la fraccion.
979 * X = 175
X = 175/979
Nos fijamos si se puede simplificar, no se puede asique este es el resultado final.
