The required number of minutes a person used the phone is 131 minutes.
Given that,
A cellular phone company charges $25 per month plus 10 per minute of phone use. A person's bill came to $38.10 for one month,
<h3>What is simplification?</h3>
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let x be the number of minutes he used the phone,
According to the question,
25 + 0.1x = 38.10
0.1x = 38.10 - 25
0.1x = 13.10
x = 13.10/ 0.1
x = 131 minutes
Thus, the required number of minutes for the given condition is 131 minutes.

the mode (rounded to the nearest tenth if needed) of the following data set is 30,29,40,51,39,33,24,60,40,35,58
scoray [572]
The mode is the number that occurs the most in the sequence of numbers, so the mode is 40 since that number is repeated the most in the sequence, 2 times.
The probability of her winning a game would be 5/9 because if she loses 4/9 games then 5/9 games must be wins.
Answer:
The first car was traveling 70 mph, while the second was driving 50 mph.
Step-by-step explanation:
Set the cars as a proportion:
X represents the speed of the second car. By cross multiplying, you get the following equation:
You solve by distributing 150 to get 210x = 150x + 3000.
Solving for x gets you 50.
That means the first car was going at 50 mph. Adding 20, you get 70 as the speed for the second car.
