Theres a diagram of a tap fully on and off 180 degrees is fully on, when fully on the tap flows at 18 litres a minute
the rate at which water flows out is in direct proportion to the angle of turn
the tap is turned to 126 degrees, the water flows into a tank with a capacity of 115.92 litres
how long in minutes will it take to fill the tank

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!

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
