The radius of the Earth is approximately 6,370 kilometers. What is the distance in scientific notation?
rosijanka [135]
The correct answer among the choices listed is the second option. The scientific notation of 6,370 kilometers is 6.370 × 10^3 kilometers. It is by this way that scientists are able to handle very large or small numbers. They just move the decimal point and multiply it by 10 raise to the power of n where n is the number of times the decimal point is moved. If to the left, then n is positive. If to the right, then n is negative.

In a triangle the measures of three angles are x, x+6,x-9. What is the measure of each angle?​
andrey2020 [161]

9514 1404 393

Answer:

  61°, 67°, 52°

Step-by-step explanation:

The sum of angle measures in a triangle is 180°.

  x +(x +6) +(x -9) = 180

  3x -3 = 180

  x -1 = 60

  x = 61

  x +6 = 61 +6 = 67

  x -9 = 61 -9 = 52

The measures of the angles are 61°, 67°, 52°.
