Answer:

Step-by-step explanation:

(You posted this as a mathematical question. The biology department should have more fun with this kind of question. :) )

My uneducated guess would be that there is no real correlation between fur-colour and gender. Fur colour is associated with habitat circumstances: Having light fur makes the mice less visible on sand and dark fur does the same for rocky areas.

All you can produce from the given data are ratios:

A 42/14 $\approx 1/4$ ratio for male mice and a 33/11 $= 1/3$ ratio for females indicates,

that there are more male mice than female in rocky areas. We also observe, that there are generally more mice living in rocky areas than on sand and that the male to female-ratio in sandy areas is pretty much balanced.

An employee at a fireworks company is designing a rocket. The rocket will consist of a cardboard circular cylinder with a height

Andreyy89

The radius of the cylinder should be approximately 2.040 inches long.

<h3>How to calculate the radius of a rocket to contain a required quantity of powder</h3>

The volume required to store the powder is the sum of the volumes of the cylinder and the cone, whose expression is in this case:

204 in³ = (π/3) · r² · (4 in) + π · r² · h

204 in³ = (4/3 + h) · π · r²

204 in³ = (4/3 + 7 · r) · π · r²

204 = (4π/3) · r² + 7π · r³

7π · r³ + (4π/3) · r² - 204 = 0

The positive roots of the cubic equation are:

r ≈ 2.040 in

The radius of the cylinder should be approximately 2.040 inches long.

URGENT!!!! THIS IS DUE TODAY!!

Answer:

Unless I am an idiot here (think I am) it is AE s the length between A and E, so it is 8

Step-by-step explanation:

Every side of the square is 16.

A to E is half of a side of the square, not a full side.

So you divide 16 by 2, getting 8.

Hope this helps, and sorry if this seems sloppy, I am new to brainly :)

Can someone help me with this please....ill give points and brainless

Answer:

The total surface area of the given cone is

$S = 4( \sqrt{3}+1)\pi cm^2$

Step-by-step explanation:

Step 1:-

Formula:-

The total surface area of cone is

$S.A = \pi r l +B$

$S.A = \pi r l +area of base$

$S.A = \pi r l+ \pi r^2$ ........(1)

Step 2:-

Given slant height $l = 2\sqrt{3} cm$

and radius of the circle (base) = 2

substituting these values in equation (1)

$S.A = \pi (2)(2\sqrt{3} ) + \pi (4)$

on simplification, we get

$S.A = \pi (4\sqrt{3}+4)$

Final answer :-

$S.A = 4 (\sqrt{3}+1)\pi cm^2$

How would I solve this? i know how to solve easier variations but not like this the question is:

IRISSAK [1]

The linear function with values of f(-1)=8 and f(5)=6 is f(x) = $\frac{-x+23}{3}$ .

What is linear function?

A straight line on the graph has the equation or formula y = f(x) = px + q is linear function .One independent and one dependent variables are present. X and Y are the independent and dependent variables, respectively. P is the y-intercept or constant term, and it also represents the value of the dependent variable. A straight line on the coordinate plane is represented by a linear function.

Here the given values are f(-1)=8 and f(5)=6.

We know that f(x)=y , Then the points are (-1,8) and (5,6).

Using slope formula ,

=> slope m= $\frac{y_2-y_1}{x_2-x_1}$
