Answer:
Apartamento B
Step-by-step explanation:
Para saber cual de los dos edificios es mas grande se tiene que calcular los metros cuadrados de cada edificio. Esto se calcula midiendo el largo del edificio por el ancho del edificio. Usando las medidas de la pregunta nos daria los siguientes metros cuadrados (m2)
Apartamento A: 6.5m * 10.2m = 66.3 m2
Apartamento B: 7.2m * 9.5m = 68.4 m2
Ahora podemos ver que el departamento B es mas grande que el apartamento A.
The answer is d 1 in = 4m
Answer:
The chemist needs to add 400mL of 40% solution.
Step-by-step explanation:
The equation
gives the percent concentration 
of the final mixture, when 
mL of the 40% solution are added.
Now we are asked, how many milliliters of the 40% solution should the chemist add to get final percent concentration 
; this is just a matter of solving the equation
and we solve it the following way:
Thus, the chemist needs 400mL of 40% solution to get 30% concentration of the final mixture.
Answer:
=16+9=25
Step-by-step explanation:
Solve x by simplifying both sides of the equation & then isolating the variable x=-4 & the negative comes in from the -12
