The person walked a distance of 120 kilometers in a time 3 hours. (Correct choice: C)

<h3>What is the length of the path covered by a person?</h3>

Herein we have the case of a person walking during a total time of three hours, whose conditions are explained mathematically by the following formula:

x = x / 3 + x / 4 + (x / 3 + 10)

x = (2 / 3) · x + x / 4 + 10

x = (11 / 12) · x + 10

x / 12 = 10

x = 120

The person walked a distance of 120 kilometers in a time 3 hours. (Correct choice: C)

A website sells used comic books. The table shows how the price of Painted Tiger, Volume 1, has changed over the last 4 months.
Ierofanga [76]
Explanation:
_______________
Price starts at: $7.37.
__________________
The first month, it increases by $0.50, so we add $0.50 to that starting value:
__________________
    $  7.37 
+      0.50
___________
    $  7.80
_____________
The second month, it decreases by $0.38, so we subtract $0.38 from our last obtained value:
___________________
    $  7.80
-       0.38
___________
    $  7.42
______________
During the third month, it increases by $0.32, so we add $0.32 to our last obtained value:
______________
    $  7.42
+      0.32
___________
    $  7.74
______________
During the fourth month, it decreases by $0.12, so we subtract $0.12 from our last obtained value:
________________________
    $  7.74
-       0.12
___________
    $  7.62; which is our answer.
_____________
How do we know our answer is reasonable?
______________
We start with: $7.37, then plus $0.50, then minus 0.38, then plus 0.32, then minus 0.12.
_______________
The "minus 0.38"and "plus 0.32" do not "cancel out" , but come close to. The "plus 0.50" and "minus 0.12"; in consideration with the above sentence; suggest that the value should be over the starting price of $7.37, but not much more than $8.00; or even less than $8.00. 
  Our answer is: $7.62; which seems "reasonable".

larisa [96]
Answer: It is a continuous random variable.

The amount of rain is a continuous random variable because it can take on all of the numbers on a number line.

For example, the actual amount of rain in April could be 1 inch. Or 1.4 inches. Or 1.45 inches. Or 1.452020980234 inches. There are an infinite possibilities for the amount of rainfall.

percentage we known is 59 1/5% (59.2%) and 59.2% of x is 148.5.

for the percentage,

x*59.2% =148.5

x*59.2/100=148.5

x=(148.5/59.2)*100

x=(2.5084)*100

x=250.84

The actual value is 250.84 .
