5 0

Answer:

1) 18

2) 6

3) 12

4) 12

5) 7

6) 9

Step-by-step explanation:

1) 2*x = 6^2, 2x=36, x = 18

2) 2*(x+2) = 4^2, 2x+4 = 16, x = 6

3) 10^2 = 5 * (x+8), 100 = 5*(x+8), x = 12

4) The altitude is 4sqrt3 using pythagorean, (4sqrt3)^2 = 4*x, 48 = 4*x, x=12

5) Altitude is sqrt63 using pythagorean, (sqrt63)^2 = 9x, x = 7

6) Altitude is sqrt72, sqrt(72+9) = 9

so.. what do you think was the shift then?

Marcella incarica Dora di aiutarla a suddividere 35 perle tra le sue tre figlie. Alla figlia maggiore vuole regalare la metà, al
Blizzard [7]

Answer:

La hija mayor recibirá 17.5 perlas, la hija del medio recibirá 11.66 perlas, y la hija menor recibirá 3.88 perlas.

Step-by-step explanation:

Dado que Marcella le pide a Dora que la ayude a dividir 35 perlas entre sus tres hijas, y quiere darle la mitad a la hija mayor, la tercera parte a la del medio y la novena a la menor y, además, Marcella quiere darle una perla a Dora como recompensa, para determinar cuántas perlas recibirá cada hija se debe realizar el siguiente cálculo:

35 / 2 = Mayor = 17.5 perlas

35 / 3 = Medio = 11.66 perlas

35 / 9 = Menor = 3.88 perlas

Así, la hija mayor recibirá 17.5 perlas, la hija del medio recibirá 11.66 perlas, y la hija menor recibirá 3.88 perlas.
