Awater tank composed of a cylinder and 2 half spheres is shown below. the tank is being filled with drinking water by using a bucket that can hold 0.34 cubic feet of water. emma is able to pour 5 full buckets into the tank every 3 minutes. how long will it take to fill the water tank completely at this constant rate? use 3.14 for pi and round to the nearest whole minute. the volume of the tank is ? ? cubic feet and it will be completely filled with water at the end of ? ? minutes. the cylinder below. < 3

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
