Answer:
El ascensor recorrió unos 39 metros
Step-by-step explanation:
Segun la pregunta cada cada piso tiene 3 metros de altura, por lo tanto para calcular los metros que recorrió el ascensor tenemos que hacer el siguiente calculo:
metros desde el primer piso al quinto piso=3 metros*4=12 metros
metros desde el quinto piso al segundo piso=3 metros*3=9 metros
metros desde el segundo piso al octavo piso=3 metros*6=18 metros
Por lo tanto los metros que recorrió el ascensor=12 metros+9 metros+18 metros
metros que recorrió el ascensor=39 metros
El ascensor recorrió unos 39 metros

Option D
Answer:
The correct option is A.
Step-by-step explanation:
Braxton is testing 2 different types of motor oil in his truck to determine which one will last longer.
Now, he adds Brand A to the truck and Brand B to his sister's car.
Now, as Braxton wants to test the motor oil in his truck so there is no need of adding the motor oil to his sister's car as by doing so he cannot result in to a meaningful conclusion.
So, Braxton need to add both the motor oil into his truck one by one.
Hence, The conclusion of Braxton is not valid because he added Brand B to his sister's car, not the truck.
Therefore, The correct option is A.
