Answer:40
Step-by-step explanation:
1)38/x=95/100
2)cross multiply: 3800=95x
3)divide each side by 95 (3800/95 and 95x/95)
4)simplify to get the answer
The given lines are perpendicular to each other.
Further explanation:
Given lines are:
Line 1: y= -9/5x + 1/5
Line 2: y= 5/9x + 2/9
As the lines are in slope=intercept form, the co-efficient of x are their slopes
Let m1 be the slope of line 1 and m2 be the slope of line 2
Then

As we can see that the product of slopes of both lines is -1. The product of slopes of perpendicular lines is -1.
The given lines are perpendicular to each other.

Answer:
50%
Step-by-step explanation:
The only numbers that are multiples of 2 are all even numbers. From 1 to 10 there are a total of 5 even numbers, meaning that only 5 sections are multiples of 2. Therefore, the probability of the arrow landing in a section that is labeled with a number that is a multiple of 2 would be
5/10 if we simplify this it would be 1/2 or 50%
Finally, we can say that the probability of the arrow landing on one of these sections is 50%
