Josie makes fruit punch by mixing fruit juice and lemonade in the ratio 1:2 She needs to make 18 litres of punch for a party.
How much of each ingredient does she need?
Fruit juice =
litres
Lemonade = litres

  Fruit juice: 6 L

  Lemonade: 12 L

Step-by-step explanation:

The fraction of the punch that is fruit juice is 1/(1+2) = 1/3. The amount of fruit juice Josie will need for 18 L of punch is ...

  Fruit juice: 6 L

  Lemonade: 12 L

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°
