Answer:
d for the first question
Step-by-step explanation:
Given
MINING A mine produces 42.5 tons of coal per hour.
Find out the how much coal will the mine produce in 9.5 hours.
To proof
As given in the question
A mine produces 42.5 tons of coal per hour i.e in the 1 hour mine produces the 42.5 tons .
Let us assume that the coal produce in the 9.5 hours be x.
than the equation becomes
x = 9.5 × 42.5
x = 403 . 75 tons
403 . 75 tons coal will the mine produces in the 9.5 hours.
Hence proved
Answer:
28BS
Step-by-step explanation:
Compré 30 libros a 40 bs cada uno;
Precio de costo = 30 × 40BS
= 1200 BS
Vendí unos pocos a 360 Bs, a 36 Bs cada uno.
Número de libros vendidos = 360 BS / 36 BS
= 10 libros
Número de libros restantes = 40 BS - 10 BS
= 30 BS
¿Cuánto debo vender cada uno de los libros restantes para no perder ni ganar nada?
Para no ganar ni perder nada, la cantidad total que queda para vender los libros =
1200BS - 360 BS = 840 BS
La cantidad para vender cada uno de los libros restantes sin ganar ni perder nada se calcula como:
840BS / Número de libros restantes
= 840BS / 30BS
= 28BS
