Answer:

v = 120

Step-by-step explanation:

If v is inversely proportional to square root of d, then we can write

v \sqrt{d} = k    

If v  = 30 and d = 400, then

30(\sqrt{400}) = k

k = 30(20) = 600

Now v \sqrt{d} = 600

If d = 25, then v\sqrt{25} = 600

                         5v = 600

                            v = 120

1. what is the area of the board shown on the scale drawing? explain how you found the area.2. how can Adam use the scale factor
bixtya [17]

Answer:

1. 1800 square cm.

2. See below

3. 45000 square cm.

Explanation:

Part 1

The dimensions of the drawing are 36cm by 50cm.

\begin{gathered} \text{The area of the board}=36\times50 \\ =1800\operatorname{cm}^2 \end{gathered}

Part 2

Given a scale factor, k

If the area of the scale drawing is A; then we can find the area of the actual board by multiplying the area of the scale drawing by the square of k.

Part 3

\begin{gathered} \text{Area of the scale drawing}=1800\operatorname{cm}^2 \\ \text{Scale Factor,k=5} \end{gathered}

Therefore, the area of the actual drawing will be:

\begin{gathered} 1800\times5^2 \\ =45,000\operatorname{cm}^2 \end{gathered}
