Only 9 members of the math club showed up for yesterday's meeting. This is only 20% of the total amount of members. How many total number of members are in the math club?

There is a total of 45 members in the math club.

Step-by-step explanation:

What I did is I multiplied 9 by 5 and got 45. I multiplied 9 by 5 because the question stated that 9 students are 20%. 20% times 5 would be 100%, which would be the total number of students.

Hope this helped :)

The answer is 45

If you worked it out it would've been simple.

20x5=100.

9x5=45.

If you turn 20% into a decimal the it will become 20 itself then you can do 20x5 to get 100, then you can use the 9 and the 5 and multiply it together then your answer is 45.

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°
