Answer:
c and e
Step-by-step explanation:
they each need to have 2 seperate numbers c and e do that!
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

<h3>
Answer: 15 & 2/3</h3>
=======================================================
Explanation:
Use a calculator or long division to find that 47/3 = 15.667
Erase the decimal portion to get 15
Then note how 15*3 = 45, which is 2 short of 47.
This means 47/3 = 15 remainder 2.
The remainder 2 portion forms the numerator of the fractional part of the mixed number.
The improper fraction 47/3 converts to the mixed number 15 & 2/3
---------------
Here's another way to do the problem
47/3 = (45+2)/3
47/3 = 45/3 + 2/3
47/3 = 15 + 2/3
47/3 = 15 & 2/3

Answer:
$250
Step-by-step explanation:
You can imagine the price of 212.5 to be 85% of the original price (100 - 15), so to do this, an easy way to find 100% is to simply divide the amount by the percentage:
Amount ÷
Simply plug the values in:
212.50 ÷ (
= 250
So the price of the tablet before markdown was $250!

Answer:
No
Step-by-step explanation:
If you draw a line, it will not go through the origin and there isn't a constant rate of change.
