Answer: a.8
Step-by-step explanation:
Given : If f(x) varies directly with x and f(x) = 2 when x = 10
We know if two quantities (x and f(x)) are directly proportional then
Now, for the given problem we have ,
Hence, if x = 40, then f(x)=8.

Which of the following best describes the situation?
A. This is an example of correlation but not causation.
B. This is an example of causation but not correlation.
C. This is an example of both correlation and causation.
D. This is an example of neither correlation nor causation.
When Sarah added the fertilizer and there was a noticeable difference, we can say that:
Causation occurs when an effect is noticed because of a traceable item. The traceable item, in this case, is the fertilizer.
So when the fertilizer was added and a change in color was noticed, we can deduce that the difference was because of the fertilizer.
Therefore, option B is correct.

Answer: B.) This is an example of causation but not correlation.
Step-by-step explanation: Causation is a cause and effect, because fertilizer was added to one plant, it's leaf color was improved.
Answer:
She will run a distance of 1095.78 miles per year.
Explanation:
Number of days in a year = 365.25
Number of days in a week = 7
Number of weeks in a year = 365.25/7 = 52.18 weeks.
Tomika plans to run 84 miles in 4 weeks.
Distance run by Tomika in 1 week = 84/4 = 21 miles.
Distance run by Tomika in 1 year = 21*52.18 = 1095.78 miles
So she will run a distance of 1095.78 miles per year.
If Tomika continues the pattern, she will run approximately 1,092 miles in a year.
There are 52 weeks in a year, so you can divide 52 by 4 to find out how many 4-week periods there are in a year:
Number of 4-week periods in a year = 52 weeks / 4 weeks/period = 13 periods
Now, multiply the miles she runs in each 4-week period (84 miles) by the number of 4-week periods in a year (13 periods):
Total miles in a year = 84 miles/period × 13 periods
Total miles in a year = 1,092 miles
So, if Tomika continues the pattern, she will run approximately 1,092 miles in a year.

6 and y = 10?
10x - 5y
Answer: 10
Step-by-step explanation: Because 10times X when X=6 is 60 then 5 times Y when Y=10 makes it 50 then subtract the two numbers
60-50=10
The value of the expression 10x - 5y when x = 6 and y = 10 is 10.
The expression given is 10x - 5y. We are asked to determine the value of this expression when x = 6 and y = 10. To do this, we replace x and y in the expression with these given values:
10*6 - 5*10 = 60 - 50 = 10
So, when x = 6 and y = 10, the value of the expression 10x - 5y is 10.
