Answer:
Las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.
Step-by-step explanation:
Podemos estimar la proporción de ingredientes mediante el siguiente promedio ponderado:
(1)
Donde:
- Masa de la solución al 20 %, en onzas.
- Masa de la solución al 40 %, en onzas.
Podemos simplificar la formula como sigue:
(2)
Donde 
es la proporción de la solución al 20 % dentro de la solución final, sin unidades.
Ahora resolvemos para en (2):
Este resultado quiere decir que la solución al 34 % es el resultado de 30 % de la solución al 20 % y 70 % de la solución al 40 %. Si conocemos que la solución final tiene una masa de 50 onzas, entonces las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.
Answer:
4.75 Qt = 152 Fl. Oz.
Step-by-step explanation:
1 Quart = 32 Fluid Ounce
4.75 Qt = 32 × 4.75 Fl. Oz.
4.75 Qt = 152 Fl. Oz.
Answer:
- The equation is: x = (y - $4) / g
Where x is the number of games you can play;
y is the amount you have
and g is the cost of each game
- You can play only 2 games
Step-by-step explanation:
From the question, you have $10 to go bowling and you need to rent shoes for $4. Hence, after renting the shoes, you will have $10 - $4 left, that is you will have $6 left. To determine the number of games you can play, that will be the amount you have left after renting shoes divided by the cost of each game.
Let the number of games you can play be x games
and the amount you have be y
and the cost of each game be g
Hence,
x = (y - $4) / g
From the question,
y = $10
and g = $3
∴ x = ($10 - $4)/ $3
x = $6 / $3
x = 2
Hence, you can play only 2 games
5/8
6/3
7/10
These are all the answers 4/8 is 1/2 and 5/8 is over it there is no half of 3 but 6/3 is 2 and 2 is a whole number it's over 1/2
5/10=1/2 and 7/10 is over it 1/4 isn't an answer because 2/4=1/2 6/12=1/2 but it says over 1/2 and finally 5/12 isn't it because like I said above 6/12 is 1/2
The half-life of the radioactive substance is 67.95 hours.
