Answer: He made 110 kilograms of 9.09% salt solution.
Step-by-step explanation:
Given: Mass of water= 100 kg
Mass of salt= 10 kg
Total mass of the solution: 100kg+10kg= 110 kg
The percent of salt in solution=
∴The percent of salt in solution
Therefore, He made 110 kilograms of 9.09% salt solution.
Shi I would say b . A is too much and so is d
Answer:
see explanation
Step-by-step explanation:
The excluded values are any values of x that make the function undefined
Given
The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the values that x cannot be.
(x + 4)(x - 2)(x - 5) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
x - 5 = 0 ⇒ x = 5
x = - 4, x = 2, x = 5 are the excluded values
