Answer:
The total weight of the metal bar in pounds is 25 pounds
Step-by-step explanation:
Now, we have a metal bar which has a content of 60% zinc corresponding to 15 pounds.
Mathematically, let’s say the total weight of the metal composite is x pounds. It is 60% of this that is 15 pounds which is the content of the zinc
Mathematically;
60/100 * x = 15
60x = 15 * 100
60x = 1500
x = 1500/60
x = 25 pounds

Answer:
y=-99x
Step-by-step explanation:
it's imposible to answer y in terms of a number, but it is possible to do it in terms of x.
x-y=100x
x=100x+y
-99x=y
y=-99x
Answer:
C = 2πr = 16.3
2(3.14)r = 16.3
r = 16.3/6.28
r = 2.5955414
Area: A = πr2
A = 3.14(2.5955414)2
A = 21.15366242 
Step-by-step explanation:
The answer would be 21.2
