Answer:
tarro corto
Step-by-step explanation:
Aquí tenemos que comprar el frasco que tiene el menor costo por volumen.
= Altura del frasco corto
= La altura del frasco alto es el doble que el del frasco corto. = 
= Diámetro del frasco corto
= El diámetro del frasco alto es la mitad del frasco corto = 
El volumen de un cilindro es 
La razón de los volúmenes de los frascos es

El costo del frasco corto por unidad de volumen es

El costo del frasco alto por unidad de volumen es


Entonces, el costo del frasco corto por unidad de volumen es menor que el costo por unidad de volumen del frasco alto.
Por lo tanto, deberíamos tomar el frasco corto.
The books are $5, and the magazines are $10. I’m not sure which way you want it explained but since magazines are twice the price of books, you can solve the equation 3b + 2b = 25. This gives you b=5 which you just multiply by 2 giving you the price of a magazine.
Add 5
y is found by adding 5 to x
Answer:
The rectangle is 3.2 cm by 12.6 cm
Step-by-step explanation:
See attached image for a diagram.
Choose <em>w</em> to represent the width because the length is described by referring to the width: it's 3 more than (add 3) triple (multiplied by 3) the width.
Length = 3w + 3
The diagonal forms two right triangles, each with leg = <em>w</em>, other leg = 3<em>w</em> + 3, hypotenuse = 13.
The Pythagorean Theorem says
so

Now solve using the Quadratic Formula with
.

The negative root makes no sense as a distance, so the width of the rectangle is 3.2 cm. The length is 3(3.2) + 3 = 12.6 cm.
