Given:
A metal is made from copper, zinc and lead in the ratio 13:6:1.
The mass of zinc is 90kg.
To find:
The mass of the metal.
Solution:
It is given that the metal is made from copper, zinc and lead in the ratio 13:6:1.
Let the mass of copper, zinc and lead are 13x, 6x and 1x respectively.
The mass of zinc is 90kg. So,
Now, total mass of the metal is:
Therefore, the mass of the metal is 300kg.
Answer:
The expression is -80x+24
Step-by-step explanation:
distribute the -8
Answer:
y=2x+2
Step-by-step explanation:
Remember that parallel lines have equal slopes. We can solve this using point slope form which is
Plug in the point (0,2) into the equation:
y-2=m(x-0)
Also plug in the slope which is the same as line EF (m=2)
y-2=2(x-0)
Simplify:
y-2=2x
Add 2 to both sides:
y=2x+2
Answer:
EFD
Step-by-step explanation:
AC/DE = AB/EF = BC/DF
So the correct order should be EFD
