Answer:

b

Step-by-step explanation:

Altitude- 0n- hypotenuse theorem

(leg of big Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse ), that is

x² = (30 - 6) × 30 = 24 × 30 = 720 ( take square root of both sides )

x = \sqrt{720}

  = \sqrt{144(5)} = \sqrt{144} × \sqrt{5} = 12\sqrt{5} → b

A candidate running for office is putting on a gala as a fundraiser, with hopes of raising more than $7,900 in political contrib
baherus [9]
The simplest interpretation would go a little something like this:

We know that we want the total donation amount to be more than $7,900, so we can set up this inequality to begin with

D \ \textgreater \ 7,900

Where D is the total donations raised (in dollars). How do we find D? Well, we just add up the total number of table reservations sold and the total number of single tickets sold. If we let r stand for the number of reservation tickets and s stand for the number of single tickets, then we have

D=540r+34s

So, the inequality representing this situation would be

540r+34s\ \textgreater \ 7,900

And that would probably be fine for this problem.

<span><em>Footnote:</em> </span>Of course, if this were a real-life scenario, we'd need to take some additional details into account: How many tables do we have? How many people can be seated at each table?
