Ned pours 7 2/5 ounces of water from a beaker contains 10.25 ounces . How much water is left?

2/5 = 0.4 as a decimal.

Now subtract:

10.25 - 7.4 = 2.85 ounces are left

could you reply to this with the question so i can ?

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!
