Lewis has a bag of colored marbles. the bag contains 24 red marbles, 36 blue marbles, and 60 yellow marbles. what are the ratios of the number of red marbles, blue marbles, and yellow marbles to the total number of marbles? a. red = 1: 5; blue = 3: 10; yellow = 1: 2 b. red = 2: 3; blue = 3: 5; yellow = 1: 2 c. red = 1: 5; blue = 3: 5; yellow = 1: 2 d. red = 1: 2; blue = 3: 10; yellow = 1: 5

The correct answer is A. Why?

We will make proportion

r : b : y = 24 : 36 : 60  we can divide whole proportion with number 12 and get

r : b : y = 2 : 3 : 5  

Red : Total = 2 : 10= 1 : 5    Blue : Total = 3 : 10  

and Yellow : Total = 5 : 10 = 1 : 2

Good luck!!!

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function

his answer is incorrect. i just used it, and it said it was incorrect. the answer is 0.
