Zina [86]

Answer:

$z = 362\,botellas$

Step-by-step explanation:

(This exercise has been presented in Spanish and for that reason explanation will be held in Spanish)

La cantidad de botellas de 0,25 litros que se llenan con 49 litros de yogurt es:

$x = \frac{49\,L}{0.25\,\frac{L}{botella} }$

$x = 196\,botellas$

La cantidad remanente de yogurt es:

$V_{r} = 132\,litros - 49\,litros$

$V_{r} = 83\,litros$

Ahora, la cantidad de botellas de 0,5 litros que se llenan con el volumen remanente es:

$y = \frac{83\,litros}{0.5\,\frac{litros}{botella} }$

$y = 166\,botellas$

Finalmente, el total de botellas a llenar es:

$z = 196\,botellas + 166\,botellas$

$z = 362\,botellas$

Javier has a model of a cone with a radius of 3 inches and a height of 10 inches. Javier increased his model’s volume by doublin

statuscvo [17]

Answer:

$240 \pi\ in^{3}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z------> the scale factor

x-----> the volume of the larger cone

y-----> the volume of the original cone

$z^{3}=\frac{x}{y}$

In this problem we have

$z=2$ -----> scale factor

substitute

$2^{3}=\frac{x}{y}$

$8=\frac{x}{y}$

$x=8y$

That means-----> The volume of the larger cone is 8 times the volume of the original cone

Find the volume of the original cone

$V=\frac{1}{3}\pi r^{2} h$

we have

$r=3\ in$

$h=10\ in$

substitute

$V=\frac{1}{3}\pi (3^{2})(10)=30 \pi\ in^{3}$

therefore

The volume of the larger cone is equal to

$8*30 \pi\ in^{3}=240 \pi\ in^{3}$

A real estate broker's base salary is $18,000. She earns a 4% commission on total sales. How much must she sell to earn $55,000

VladimirAG [237]

The salary of the real estate broker = $18,000

Commission earned on total sales = 4% or 0.04

Total income earnings = $55,000

Let the total sales be = x

Equation becomes :

$18000+0.04x=55000$

$0.04x=55000-18000$

$0.04x=37000$

$x=925000$

Hence, the real estate broker must sell $925,000 worth of real estate to earn $55,000.
