The luminosity of a star can be calculated by using the following equation. In the luminosity equation, represents the luminosity in watts, represents the radius of the star in meters, represents a constant equal to 5.67 × 10-8 Wm-2K-4, and represents the surface temperature in Kelvins.

What is the approximate radius of a star with a luminosity equal to 2.532 × 1021 W and a surface temperature of 3,000 K? (Use = 3.14)

the answer is. -82562234434584

step-by-step explanation:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
