Tim and Ollie share some money in the ratio 2:5
Tim gets £80
Work out how much Ollie gets.

£200

Step-by-step explanation:

The ratio is 2:5

we then have

80:x

Because one side of the ratio was multiplied by 40 we have to do the same to the other

20*5=200

therefore our new ratio is

80:200

Ollie gets £200

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

2.2°  

step-by-step explanation:

let θ = the angle of elevation.

tanθ =77/2020

tanθ = 0.038 12

      θ = tan⁻¹0.038 12

      θ = 2.2°
