Answer: - $\frac{1}{12}$

Step-by-step explanation:

Lets make the demonater both equal $\frac{4}{6}$ = $\frac{16}{24}$ , $\frac{6}{8}$ = $\frac{18}{24}$

$\frac{16}{24}$ - $\frac{18}{24}$ =- $\frac{2}{24}$

Simplify it and it's - $\frac{1}{12}$

Hope this helped! :)

A cone and a sphere both have a radius of 1. If you fill the cone with liquid, and pour it into the sphere, it fits exactly. Wha

PtichkaEL [24]

Answer and Step-by-step explanation:

First, solve for the volume of the sphere, then solve for the height of the cone using the volume of the sphere (which is said to be equal to the volume of the cone) and the radius given.

Volume formula of Sphere

V = $\frac{4}{3} \pi r^2$

Substitute 1 in for r

$\frac{4}{3} \pi (1)^2 = \frac{4}{3} \pi = 4.189$ = Volume

Finding the Height of a Cone

Volume formula for Cone: $V = \pi r^2\frac{h}{3}$

Solve for h

Multiply both sides by 3, then divide by pi and r^2.

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

Plug in the volume and the radius.

$h = \frac{3(4.189)}{\pi (1)^2}$

Simplify

$h = \frac{12.567}{\pi }$

h ≈ 4

4 is approximately the height.

On Mercury, you weigh 2 pounds for each 5 pounds you weigh on Earth. You weigh 140 pounds on Earth. How much do you weigh on Mer

MissTica

Answer:

Step-by-step explanation:

Givens

Given Ratio = 2/5

Given mass on earth = 140

Ratio

2/5 = x/140 or

0.4 = x / 140

Solution

2/5 = x/140 Cross multiply

5x = 2*140 Combine

5x = 280 Divide by 5

x = 280/5

x = 56

You could also do this by combining the left side of the original proportion into 0.4

0.4 = x / 140 Multiply both sides by 140

0.4*140 = x Combine the left

56 = x

The fish population in a pond with carrying capacity 1200 is modeled by the following logistic equation where N(t) denotes the n

MArishka [77]

9514 1404 393

Answer:

(dN)/(dt) = (0.4)/(1200)N(1200-N) -50

142 fish

Step-by-step explanation:

A) The differential equation is modified by adding a -50 fish per year constant term:

(dN)/(dt) = (0.4)/(1200)N(1200-N) -50

B) The steady-state value of the fish population will be when N reaches the value that makes dN/dt = 0.

(0.4/1200)(N)(1200-N) -50 = 0

N(N-1200) = -(50)(1200)/0.4) . . . . rewrite so N^2 has a positive coefficient

N^2 -1200N + 600^2 = -150,000 +600^2 . . . . complete the square

(N -600)^2 = 210,000 . . . . . simplify

N = 600 + √210,000 ≈ 1058

This steady-state number of fish is ...

1200 - 1058 = 142 . . . . below the original carrying capacity
