Just divide the number that is biggest by 2 and you should get the answers for example #1 10÷2=5, #2 1÷2=0.5 #3 0.01÷2=0.005
we just did this in math-
In order for two lines to be perpendicular, their slopes must multiply together to equal to negative one
So we do negative one divided by 2/5 to get the slope of the red line
Which is -5/2
To check, we do 2/5 multiplied by -5/2 which equals to -1 so our answer is correct
Answer:
0.0000454
Step-by-step explanation:
The zeros are not significant since they come before the numbers greater than 0. And I rounded 3 to 4 since the 8 was above 5 so it gets rounded up
