Answer:
Since a₁ = 36 and d = 1/3 the formula for this geometric sequence is aₙ = 36(1/3)ⁿ⁻¹ which means a₆ = 36 * 1/3⁵ = 0.148.
-2.9a + 6.8 + 4.4a - 7.3
Combine like terms.
1.5a - 0.5 is your answer.
Answer:
the second i think i dont know for sure
Yes.
8 + 1 + 1 = 10, so there are 10 parts to the ratio.
3.5 litres divided by 10 would mean that each part of the ratio is worth 0.35 litres.
The colour is worth 8 parts of the ratio. 0.35 litres multiplied by 8 would give 2.8 litres, meaning 2.8 litres of colour are required.
Fiona has 2.9 litres of colour, which is more than enough to make 3.5 litres of paint mix.
