Answer:

F = 6

Step-by-step explanation:

When something is inversely proportional to another thing, when one of the numbers increases or gets multiplied by a constant, the other number decreases or gets divided by a constant.

In this scenario, when F = 3, d = 4.

When d = 2, we are dividing the earlier value of 4 by 2. Now, since F is inversely proportional to d, we have to multiply the value of F by 2 to get what F equals when d = 2. 3 times 2 is 6, so F = 6 when d = 2.

I am so stuck! :( Pls help me!!! I don't get the problem and I don't know how to solve it

Lelu [443]

Answer:

$\frac{n^{2}}{2a}$

Step-by-step explanation:

Just split it up first $\frac{9an^{3}}{18a^{2}n}=\frac{9}{18}\times \frac{a}{a^2} \times\frac{n^3}{n}$
Then 9 divided by 18 can be simplified into the fraction 1/2
What can go into $a$ and $a^2$ ? a itself right, so if you divide a by a you get 1, if you divide $a^2$ by a you get a
Same as the a fraction, if you divide $n^3$ by n you get $n^2$
$\frac{9an^{3}}{18a^{2}n}=\frac{9}{18}\times \frac{a}{a^2} \times\frac{n^3}{n}=\frac{1}{2}\times \frac{1}{a} \times\frac{n^2}{1}=\frac{n^{2}}{2a}$

A field has a length of 12 m and a diagonal of 13 m what is the width?

kvv77 [185]

Do Pythagorean Theorem because a rectangle divided in diagonals form right triangles
A^2+b^2=C^2
Plug in the correct numbers and solve
A and B can be switched around but C is always the longest diagonal side which is called the hypotenuse not the Adjacent sides that form a right angle
So with correct solving you should get 5.
