Density = 0.8 g/cm³
Volume = 9000 cm³
D = m / V
0.8 = m / 9000
m = 0.8 x 9000
m = 7200 g
hope this helps!
The first one it goes up in the same increments
The full answer is so long. I’m too lazy to do it but i can tell u how.
First write the equation of line AB then equation of line CD then compare the slope of both line AB and CD.
Answer:
a, y =3/x
x = 0.5 => y = 3/0.5 = 6
x = 1 => y = 3/1 = 3
x = 2 => y = 3/2 = 1.5
x = 3 => y = 3/3 = 1
x = 4 => y = 3/4 = 0.75
b,
y = 3/x passes (0.5, 6) => A is correct
Hope this helps!
1 is 4 times greater than 1/4
If you multiply 1/4 by 4 you get 1
