An oil storage tank that holds 48,000 barrels is one-quarter full. Oil is being pumped into the tank at the rate of 600 barrels per hour. The quality control crew that will draw samples when the tank is full wants to know how may days it will take to complete the fill so that they can set the sampling schedule.

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!

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6

answer is b.
