Answer:
Todos los lados de un cuadrado son iguales. Hay 4 lados en un cuadrado. Entonces, para encontrar un lado, debemos dividir el área por 4.
432/4 = 108, Un lado del cuadrado mide 108 metros.
Answer:
That's correct.
Step-by-step explanation:
I'm pretty sure...
sin(θ) = ⁻⁴/₅
sin⁻¹[sin(θ)] = sin⁻¹(⁻⁴/₅)
θ ≈ -53.13
tan(θ) > 0
tan(53.13) > 0
1.33 > 0
Answer:
9
Step-by-step explanation:
Since we know the number of contestants in Round 2, we could go step by step and calculate the number of remaining contestants in Round 3, then Round 4 and finally Round 5.
However, we can do it without calculating. So in Round 3, there will be:
R3 = R2^((n-1)/n), where n is number of the round
R3 = R2^(2/3)
For Round 4, the number will be:
R4 = (R2^(2/3))^(3/4)
And Round 5 will be:
R5 = ((R2^(2/3))^(3/4))^(4/5)
Threes and fives in exponents will cancel out and we'll remain only with:
R5 = R2^(2/5)
R5 = 249^(2/5)
R5 = 9.08
Rounded to the nearest integer, the number of contestants in Round 5 is 9.
