On a scale drawing, a helicopter is 2.3 feet long. The scale on the drawing shows a ratio of 1 foot to 10 feet. What is the actu
andrey2020 [161]

Answer:

The actual length of the helicopter is <u>23 feet</u>.

Step-by-step explanation:

Given:

On a scale drawing, a helicopter is 2.3 feet long.

The scale on the drawing shows a ratio of 1 foot to 10 feet.

Now, to find the actual length of the helicopter.

Let the actual length of helicopter be x.

On scale drawing length of helicopter = 2.3 feet.

The scale on the drawing shows a ratio = 1:10.

Now, as ratios are given so by setting proportion we solve it:

\frac{2.3}{x} =\frac{1}{10}

<em>By cross multiplying we get:</em>

⇒ 2.3\times 10=x

⇒ 23=x

⇒ x=23\ feet.

Therefore, the actual length of the helicopter is 23 feet.

2) What is the value of this collection of base<br> ten blocks if the<br> = 1?
Alex

Answer:

Step-by-step explanation:

So the single blocks are 1, the lines are 10, the single layer is 100 and the blocks are 1000.  Let em know if you don't quite get that.  But to find how many blocks are there in total we add each part.

1 block + 2 surfaces + 3 lines +6 single little blocks.    that's one 1,000, two 100s, three 10s and six 1s or in other words 1,000 + 200 + 30 + 6 = 1,236
