If the ratio of silver nail paints to golden paints is 4 to 2 and there are total 60 nail paints, how many of them are golden?

20,

So, there are 6 total parts,

X = 60/6

Each X = 10

So, 10*2 = 20

20 of them are golden.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
