Answer:
14g zinc
Step-by-step explanation:
To get the mass of zinc in the metal bar, you can multiply the percentage of zinc by the total mass.
40g x .35 = 14g zinc
B is just simply the y intercept
A closed circle means that value is included, and an open circle means that value is excluded.
Example:
x > 2 ---- Graphed with an open circle, everything greater than but not including 2
x ≤ 3 ------ Graphed with a closed circle, everything less than and including 3
Answer:
The y intercept is 3
(0,3)
Step-by-step explanation:
4x+2y=6
To find the y intercept, set x =0 and solve for y
4(0) +2y = 6
0+2y = 6
Divide by 2
2y/2 = 6/2
y =3
The y intercept is 3
(0,3)
