The amount of water remaining in a fish tank is given by the equation y = 175 - 15x where y is the number of gallons of water remaining
fter x minutes,
that is the approximate time it would take to drain the fish tank?
a. 12 minutes
b. 85 minutes
c 160 minutes
d. 175 minutes
e. 190 minutes

The correct answer is A. 12 minutes.

Step-by-step explanation:

Let's solve for y, when x = 12, as follows:

y = 175 - 15x

y = 175 - 15 * 12

y = 175 - 180

y = - 5

This result means that after 12 minutes the fish tank would be completely drained and if it's needed 5 additional gallons of water could also be drained. It's not necessary to continue making more calculation with the the other options given because this is the right answer.

The correct answer is A. 12 minutes.

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
