She ought to select the monthly plan for unlimited movies instead of paying $2.99 per film. This choice is advisable because if she continues paying this amount for each individual movie, her total monthly costs will rise significantly. For example, if she has 8 days off in a month (on Saturdays and Sundays) and pays for each film on those days, the total expense would exceed that of the unlimited monthly plan priced at $7.99. And that doesn't include other potential viewing days or any public holidays that could allow her to watch more movies.
{chocolate, strawberries, peanuts} Explanation: Given three sets, let A = {vanilla, chocolate, hot fudge, strawberries, sprinkles, peanuts, whipped cream}, let B = {vanilla, hot fudge, sprinkles, whipped cream}, and let C = {chocolate, hot fudge, peanuts, whipped cream}. Thus, the universal set U = A ∪ B ∪ C = {vanilla, chocolate, hot fudge, strawberries, sprinkles, peanuts, whipped cream}. B' consists of the elements found in U but not in B, which results in: {chocolate, strawberries, peanuts}.
Answer:
720 formas posibles
Explicación paso a paso:
La medalla de oro se otorga al primer lugar, la medalla de plata al segundo lugar y la medalla de bronce al tercero.
Cualquier corredor entre los 10 puede ocupar la primera posición.
La segunda posición puede ser ocupada por los 9 corredores restantes.
Mientras que la tercera posición puede ser ocupada por los 8 corredores que quedan.
Por lo tanto, el número de formas en que se pueden otorgar estas medallas es = 10 * 9 * 8 = 720 formas.
Answer: A square that undergoes rotation around its center by 360º aligns with itself at D) 4 distinct angles during the process. Furthermore, a square can be reflected onto itself over B) 4 various lines.
Explanatory breakdown:
A square is a geometric shape characterized by equal-length sides and right angles ( 
).
Thus, it is capable of being rotated around its center by 
.
It reverts to its original outline at 4 unique rotation angles ( at every 
).
The square can also be reflected onto itself across 4 lines (2 through the non-parallel sides and 2 through the corners).
