If Georgia is 59,424.77 square miles, then what is the area of Georgia rounded to the nearest square mile?

Answers

59,424.77 rounded to the nearest square mile would be 59,425 because the .77 would get rounded up to a 1. That 1 gets added to the 424, hence 59,425.
59,424.77's tenths is 7 which means we had to rounded up instead of keeping the ones, so if we add the 1 that had represented the 7 on the tenths, then 59,424+1=59,425, which means the answer would be 59,425.

Sum of all three side of a triangle = 180

x + (3x +13) + (x - 8) = 180
x + 3x + 13 + x - 8 = 180
5x + 5 = 180
5x = 180 - 5
5x = 175
x = 175/5
x = 35

Angle A:
3x + 13
3(35) + 13
105 + 13
118

Answer: Angle A = 118 (Answer matched)

//Hope this helps

m∠A = 118 degrees (Angle ∠A is 118 degrees when you substitute x = 35 into the expression (3x + 13)).

In this problem, we are given three angles of a triangle: ∠A, ∠B, and ∠C, expressed in terms of the variable x. We need to find the measure of angle ∠A.

1. Start with the given information:

  - ∠A = (3x + 13) degrees

  - ∠B = (x - 8) degrees

  - ∠C = x degrees

2. We know that the sum of the angles in any triangle is always 180 degrees. So, we can write an equation based on this fact:

  ∠A + ∠B + ∠C = 180

3. Substitute the expressions for each angle:

  (3x + 13) + (x - 8) + x = 180

4. Now, simplify and solve for x:

  3x + 13 + x - 8 + x = 180

  Combine like terms:

  5x + 5 = 180

  Subtract 5 from both sides to isolate 5x:

  5x = 180 - 5

  5x = 175

  Divide by 5 to find the value of x:

  x = 35

5. Now that we've found the value of x, we can find the measure of ∠A by substituting x back into the expression for ∠A:

  ∠A = (3x + 13)

  ∠A = (3 * 35 + 13)

  ∠A = 105 + 13

  ∠A = 118 degrees

So, the measure of angle ∠A is 118 degrees.

5/6 k equals 1/6 is the answer

Answers

(5)/(6) k = (1)/(6)

Refine 

(5)/(6) k = (5k)/(6)

(5k)/(6) = (1)/(6)

Multiply both sides by 6 :

(5k)/(6) *6= (1)/(6) *6

5k = 1

Divide both sides by 5 :

(5k)/(5) = (1)/(5)

k= (1)/(5)
