You will do -1.42 + 3.8 because two negative is positive.
So the answer is C. 2.38
X=7.
9x-7y=63
9x-7 x 0=63
9x - 0=63
9x=63
X=7.
Y=-9
9 x 0 -7y=63
Answer:
144
Step-by-step explanation:
first digit of the code: only 2 and 4 are the only even numbers availible, so only 2 possibilities for the first digit.
2nd digit of code: 2,5,7,9,1 so 6 possibilities for the 2nd digit.
3rd digit of code: 2,5,7,9,1 so 6 possibilities for the 3rd digit.
4th digit of code: only 7 and 9 are greater tyhan 6 so only 2 possibilities for the 4th digit.
SO...
2 x 6 x 6 x 2 = 144
Volume of cylinder =Π r^2 h
where 'r' refers to radius and 'h' refers to height of the cylinder
volume of cylinder = Π (2)^2 (6)
= Π (4)(6)
=Π (24)
75.36 cm^3 is the volume of the cylinder.
