Answer:

b = \frac{kv}{k+rt}

Step-by-step explanation:

Given

k = \frac{brt}{v-b} ← multiply both sides by (v - b)

k(v - b) = brt ← distribute left side

kv - kb = brt ( subtract brt from both sides )

kv - kb - brt = 0 ( subtract kv from both sides )

- kb - brt = - kv ( multiply through by - 1 to clear the negatives )

kb + brt = kv ← factor out b from each term on the left

b(k + rt ) = kv ← divide both sides by (k + rt )

b = \frac{kv}{k+rt}

United States flags come in different sizes. Standard dimensions for a flag are a length to width ratio of 1 : 9 to 1. Flag 1 ha
frez [133]

Answer:

5.13 feet

Step-by-step explanation:

So, we have the full dimensions of flag #1, and we have the partial dimensions of flag #2, which should follow the same ratio as flag #1, since not indicated otherwise.

When you need to compare dimensions like that, the easiest way to proceed is to do a cross-multiplication. Let's say x is the length of flag #2 we're looking for.  It's ratio over the width of flag #2 will be the same as the ratio of the length of flag #1 over its width, so:

\frac{x}{2.7} = \frac{1.9}{1}

If we isolate x, we have x = (2.7 * 1.9) / 1 = 5.13 feet

Which makes sense since we know the result should be a bit less than 2.7 times 2.
