A scale of 8cm:12cm would be a scale of 2/3. since this is the case, we can divide the scale drawing of the playground by the scale factor to get the length of the actual playground

12.4/0.6666 = 18.6

The answer is 18.6

11) a - 15 &gt;-40-6 + 3a)<br>​
SOVA2 [1]

Answer:

a < \frac{31}{2}

Step-by-step explanation:

Given

a - 15 > - 40 - 6 + 3a ← simplify right side

a - 15 > - 46 + 3a ( subtract a from both sides )

- 15 > - 46 + 2a ( add 46 to both sides )

31 > 2a ( divide both sides by 2 )

\frac{31}{2} > a ⇒ a < \frac{31}{2}
