In a bag of red and green sweets, the ratio of red sweets to green sweets is 3:4 If the bag contains 12 green sweets, how many red sweets are there?

Given:

The ratio of red sweets to green sweets is 3:4.

Total number of green sweets = 12

To find:

The total number of red sweets.

Solution:

We have,

The ratio of red sweets to green sweets = 3:4.

Let the number of red sweets and green sweets are 3x and 4x respectively.

Total number of green sweets = 12

Divide both sides by 4.

Now,

Number of red sweets =

                                       =

                                       =

Therefore, the number of red sweets is 9.

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°
