Answer 1

Answer:

Step-by-step explanation:

To find this, we are going to use the combination formula as follows;

nCr = n!/(n-r)!r!

In this case, n = 7 and r = 3

Substituting these values;

7C3 = 7!/(7-3)! 3! = 7!/4!3! = 35

V= Bh/3 solve for h.

Answers

The equation $h = (3V)/(B)$ gives the value of h in terms of V (volume) and B (base area) for the given equation $V = (Bh)/(3)$ .

Given equation: $V = (Bh)/(3)$

Step 1: Multiply both sides of the equation by 3 to isolate Bh:

$3V = Bh$

Step 2: Divide both sides of the equation by B to solve for h:

$h = (3V)/(B)$

So, the equation solved for h is:

$h = (3V)/(B)$

This gives you the value of h in terms of V (volume) and B (base area) for the given equation $V = (Bh)/(3)$ .
