Jefferson school has students in 1st grade up to 5st grade. The number of children in 1st grade has 3 digits. The digit in the number are 2,3,and 8 .The digit 8 means 80 in the number write the number that could be the number of children in 1st grade.

283 or 382

Step-by-step explanation:

The number of children in 1st grade has 3 digits.The digit in the number are 2,3,and 8 .

Since the digit 8 means 80 in the number. The other two numbers could interchange the Hundred and Unit position respectively.

The possible numbers are:

I. 200+80+3=283

II. 300+80+2=382

The possible number of children in 1st Grade is either 283 or 382.

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer

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°
