Answer:
x = 5.
Step-by-step explanation:
Thew inside angles between 2 parallel lines as in the diagram add up to 180 degrees. So:
25x + 5 + 50 = 180
25x + 55 = 180
25x = 180 - 55
25x = 125
x = 5.
The function ought to be represented as; m(t) = 7t + 25 where t is the number of yards that she mows.
<h3>What is a linear function?</h3>
The term linear function refers to a function that yields a straight line graph when it is plotted. Now we know that a linear function would not contain an exponent that is greater than one.
In this case, we know that the question states that she charges a base fee of $25 and $7 for every hour she mows thus the function ought to be represented as; m(t) = 7t + 25 where t is the number of yards that she mows.

Answer:
The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
Step-by-step explanation:
As the test is targeted to 18-to-29-year-old adults using social media, we want to know the probability that a randomly selected adult uses social media and belong to the study group.
To achieve this, we have this data:
- 36% of all adults do not use social media
- 75% of all adults are >30 years old.
- The percentage of population that is <em>either</em> 18-29 years old <em>or</em> uses social media is 66.7%
Using the last data we have that
The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
The answer would be 93.887
