the amount of time that she runs on the n-th day is:
T = 4min*n + 11min
And on day number 30 is:
T = 4min*30 + 11min = 133min
<h3>
How long did she run on the 30'th day?</h3>
We know that:
She ran for:
- 15 minutes on the 1* day
- 19 minutes on the 2nd day
- 23 minutes on the 3rd day
- 27 minutes on the 4th day.
So on each consecutive day that she runs, she adds 4 minutes to the running time. This is a linear relationship.
So, if we define n as the day number, we can write the time T of running as:
T = 4min*n + b
Where b is a constant, notice that when n = 1 (the first day) the time of running is 15 minutes, then:
15 min = 4min*1 + b
15 min - 4min = 11 min =b
Then the amount of time that she runs on the n-th day is:
T = 4min*n + 11min
And on day number 30 is:
T = 4min*30 + 11min = 133min

Answer:
Hank is correct
Step-by-step explanation:
With parallel lines intersected by the same line, all corresponding angles are equal. Also remember that the two angles the are formed on each line need to add to 180 degrees. So we can take the two given angle: 7x+10 and x + 10 and add them. x + 10 + 7x + 10 = 8x + 20 = 180
So Hank has the correct equation.
Let x be the mileage that will cost the same
37.95 + 0.4x = 42.95 + .3x
0.4x - 0.3x = 42.95 - 37.95
0.1x = 3
x = 30
Ans: 30 miles
Answer:
x=73, y=107, z=73
Step-by-step explanation:
Each horizontal should equal 180 therefore x would be 180-107 and so on.
