Answer:
0.4kg, 1.4kg and 1.8kg
Step-by-step explanation:
Given parameters:
Mass of alloy = 3.6kg
Ratio of elements in the alloy = 2:7:9
Unknown:
Mass of each element in the alloy = ?
Solution:
To find the mass of each element in the alloy, first find the sum of the ratio;
2+7+9 = 18
Mass of nickel = 
x 3.6 = 0.4kg
Mass of zinc = 
x 3.6 = 1.4kg
Mass of copper = 
x 3.6 = 1.8kg
The mass of each metal is 0.4kg, 1.4kg and 1.8kg
V = 4/3πr^3V = 4/3 (π) (6.5)^3
V = 366.1666π (6 repeat)
answer is 366.16 π (3rd choice)
Answer:
The corresponding element in the range when 5 is an element in the domain is 
Step-by-step explanation:
Given that the 5 is an element in the domain of f(x)
The function f is defined by 
To find the corresponding element in the range:
That is put x=5 in the given function f(x)
Therfore f(x) becomes
Therefore corresponding element in the range when 5 is an element in the domain is
Answer:
V = 15/4π = 3.75π
Step-by-step explanation:
V=πr^2h
V=π(1/2^2)15
V=π(1/4)15
V=15/4π
Answer: 0.24
Step-by-step explanation:
You have to multiply the percent by its decimal form and then you multiply the decimal by the cost of the meal
