There are 18 female students and 16 male students in a class. Which of the following expresses the ratio of female students to m

fiasKO [112]

Hey!

-------------------------------------------------

Solution:

The ratio is FEMALES to MALES.

So its 18/16, 18:16, or 18 to 16.

~Now we need to simplify.

18:16 → 18/2:16/2 → 9:8

*Note* When you have a ratio you need to know which comes first. If you put males to females that incorrect. It has to be correct according to the question.

-------------------------------------------------

Answer:

$\large\boxed{B)~9~to~8}$

A large bag contains 5/12 pounds of nails. How many 1/8 pounds bags can be filled with this amount of nails?

Amanda [17]

so, three bags can be filled and 0.33 or 0.33*(1/3) =11/100 nails will be left

Step-by-step explanation:

We will get the number of bags that can be filled from 5/12 by dividing the total amount by the 1/8

Given

Total nails in bag = 5/12 pounds

The capacity of small bag = 1/8 pounds

So,

$Number\ of\ bags = \frac{\frac{5}{12}}{\frac{1}{8}}\\Simplifying\\=\frac{5}{12}*\frac{8}{1}\\=\frac{40}{12}\\=3.33\ bags$

so, three bags can be filled and 0.33*(1/3) = 11/100 nails will be left

Among all right circular cones with a slant height of 24, what are the dimensions (radius and height) that maximize the volum

aleksklad [387]

Answer:

5571.99

Step-by-step explanation:

We need to use the Pythagorean theorem to solve the problem.

The theorem indicates that,

$r^2+h^2=24^2 \\r^2+h^2=576\\r^2=576-h^2$

Once this is defined, we proceed to define the volume of a cone,

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

Substituting,

$v=\frac{1}{3} \pi (576-h^2)h\\v=\frac{1}{3} \pi (576h-h^3)$

We need to find the maximum height, so we proceed to calculate h, by means of its derivative and equalizing 0,

$\frac{dv}{dh} = \frac{1}{3} \pi (576-3h^2)$

$\frac{dv}{dh} = 0$ then $\rightarrow \frac{1}{3}\pi(576-3h^2)=0$

$h_1=-8\sqrt{3}\\h_2=8\sqrt{3}$

<em>We select the positiv value.</em>

We have then,

$r^2 = 576-(8\sqrt3)^2 = 384\\r=\sqrt{384}$

We can now calculate the maximum volume,

$V_{max}= \frac{1}{3}\pi r^2 h = \frac{1}{3}\pi (\sqrt{384})^2 (8\sqrt{3}) = 5571.99$
