Ming plays video games online. when he signed up with the game site, ming got 200 points. ming earns 20 more points for each hour that he plays. how many hours does ming have to play to get to 500 points?

Ming has to play for 15 hours to earn 500 points.

Step-by-step explanation:

1. Make an equation: 200 + 20h = 500 pts

2. 500 - 200 = 300

3. 300 / 20 = 15

h = 15 hours

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

3 is greater then both of those numbers
