(50 yards/minute) x (3 feet/yard) x (1 minute / 60 seconds)
= (50 · 3 · 1 / 60) (yard-feet-minute) / (minute-yard-second)
= 2.5 feet/second .
Answer:
Step-by-step explanation:
Supplementary angles are angles equal to 180°.
Therefore:
Now that we have our equation, let's distribute the 
and the 
into the parentheses they are next to:
Combine like terms:
Subtract 
from both sides of the equation:
Divide by the coefficient of 
, which is 
:
~
Check your work by substituting 
into one of the equations above:
It's correct!
Answer:
yes, no, yes
Step-by-step explanation:
To the best of my knowledge, this is what I gather the table's values mean:
"antibodies present" and "positive" give you the percent of people who had the antibodies and the tests showed they did (hence, positive).
"antibodies present" and "negative" give you the percent of people who did have the antibodies, yet the tests read otherwise (misdiagnosed, negative when it should be positive).
"antibodies not present" and "positive" also show a percentage of people who were misdiagnosed. these people did not have the antibodies yet they tested positive for them.
"antibodies not present" and "negative" show the percent of people who did not have the antibodies and who were tested to prove just that.
