Answer:
a
Generally given that the number of cups of blue to that of red paint is 3: 1 then the Lara mixed 3 cups of blue paint with 1 cup of red paint
b
The number is 
c
The price is 
Step-by-step explanation:
From the question we are told that
The ratio of the number of cups of blue paint to the number of cups of red paint is 
Generally given that the number of cups of blue to that of red paint is 3: 1 then the Lara mixed 3 cups of blue paint with 1 cup of red paint
Given that 1 cup of red paint => 3 cups of blue paint
x cup of red paint => 1 cup of blue paint
So
=>
Generally the unit price of a cup of blue paint is mathematically represented as
=>
You would half to take 8×(8×pi r squared)
75,314 because it is only 5 numbers so this is correct.
You take how much she makes and multiply it by the hours she works
10.25*7
=71.75
Answer:
B
Step-by-step explanation:
Recall that functions are defined only if for each value in the domain produces one and only one value in the range.
If we view the relations in the questions as x-y coordinates, this means that for every x-value, you can only have one y-value
Lets evaluate the options:
A) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)
C) we can see that for x = 3, this gives 2 possible values for y i.e (3,-8) and (3,8) (hence this is not a function)
D) we can see that for x = -3, this gives 2 possible values for y i.e (-3,4) and (-3,8) (hence this is not a function)
the only choice where this doesn't occur is choice B
