Answer:

45 segundos.

Step-by-step explanation:

Un tren pasa por delante de un puente en 15 segundos; si el puente tuviera el doble de longitud, le tomaría el doble de tiempo en cruzarlo, si tuviera el triple de longitud, le tomaría el triple de tiempo y así sucesivamente.

En este caso, la pregunta es ¿En cuánto tiempo cruzaría el puente si tuviera el triple de su longitud? Por lo tanto, si cruza el puente en 15 segundos, teniendo el triple de longitud le tomaría 3 (15) = 45 segundos en cruzarlo.

Solve (Y+5)^3/2=4 where y is a real number
koban [17]

Answer:

y {}^{2}  + 10y =  - 33.5

Step-by-step explanation:

(y+5)(y+5)x3/2=4

Y(y+5)+5(y+5) x 3/2=4

y {}^{2}  + 5y + 5y + 25 \times 3  \2 = 4

y ^{2}  + 10y + 75 \2 = 4

y {}^{2}  + 10y + 37.5 = 4

y {}^{2}  + 10y = 4 - 37.5

y {}^{2}  + 10y =  - 33.5

Angelique had 20 tokens to use for games at the arcade. She lost some of them. Her dad tripled the tokens she had left. Angeliqu
alexandr402 [8]

Answer:  Both the expressions are exactly same . Both are representing the number of tokens she has now.


Step-by-step explanation:

Given: The total number of tokens Angelique has= 20

Since, she lost some of them, let the number of lost tokens be t.

Then, The remaining  tokens she has = 20-t

Then her father triples the tokens she has.

now, the number of token she has=3(20-t)....>Angelique's expression

By using distributive property,

The number of token she has=3\times20-3t

⇒The number of token she has=60-3t...> Dante's expressions

Hence, both are the same expressions. Both are representing the number of tokens she has now.

<em>(A). x ≥ </em>\frac{16}{5}<em> and x ≤ - </em>\frac{3}{4}<em> </em>

Step-by-step explanation:

5x - 4 ≥ 12 ⇔ 5x ≥ 16 ⇒ <em>x ≥ </em>\frac{16}{5}<em> </em>

<em>and </em>

12x + 5 ≤ - 4 ⇔ 12x ≤ - 9 ⇔ 4x ≤ - 3 ⇒ <em>x ≤ - </em>\frac{3}{4}
