Answer:
B. 5 hours
Step-by-step explanation:
If the train is going 60mph and we need to find out how long it will be until it is traveling 80mph then we have to do 80-60=20 to figure out how much the speed is changeing. Since every hour the speed increases by 4mph then we have to do how much the train is increasing divided by how much it increases per hour.
20÷4=5
Therefore it will take 5 hours
Answer:
The answer is C.
Step-by-step explanation:
In the graph above, it is a positive gradient so option A and B cannot be applied.
Next you have to look at the y-intercept where the line touches the y-axis so -1 is the y-intercept.
The slope-form equation is y = mx + b where m represents gradient amd b is y-intercept :
Option A,
Option B,
Option C,
Answer:
k = 11 let me know if you don't understand how I got this.
Step-by-step explanation:
I'm gonna write it out
U V total
S 26 42 68
T
21 k 32
Total 47 53 100
So, you want to look at the column and row labeled total, this is the key. for the row total, it sums up everything in the column above it. so for the u column, the total value is 47 while the two values above it are 26 and 21. These two values sum to 47. This is the same for all other columns, and you can use the same reasoning with the total column as well summing rows.
This gives you two ways to solve for k. either 21 + k = 32 or 42 + k = 53. Either way gets you the answer k = 11
