Answer:
33
Step-by-step explanation:
The base/square:
3*3 = 9
The sides:
(3*4)/2 = 6
4 sides:
6*4 = 24
Total:
24+9=33
sin45=5/x so x is 5/(sin45)
y is 5/(tan45)
question 5 then you just go x= (9sqrt(2)/2)/sin45
i don’t have a calculator rn so just plug it into it
To find the mean you add up all the numbers then divide the answer by the amount of numbers there are
in this case we add 28+ 18+ 19+ 18+ 17 then divide by 5
THE MEAN IS 20!!!
-HAVE A NICE DAY!!!
I think it is a Convience Sampling.
Answer:
No solution
Step-by-step explanation:
Substitution is done by substituting one equation into another. To begin solve one equation for a variable.
Substitute y=-4x+3 into -4x-y=-2.
-4x -(-4x + 3) = -2
-4x + 4x - 3 = -2
-3=-2
This is a false statement and there is no variable present anymore. This means the equations have no solution.
