A large aquarium of water is being filled with a hose. Due to a problem, the sensor
does not start working until some time into the filling process. The sensor starts its
recording at the time zero minutes. The sensor initially detects the tank has 225 liters
of water in it
a. The hose fills the aquarium at a constant rate of 15 liters per minute. What will
the sensor read at the time 5 mintes?

300 liters.

Step-by-step explanation: It says we gain 15 liters per minute. Therefore, by simply taking 15 and multiplying it by 5, we get 75. We then add that to what the sensor has, due to it not having any time once it reached 225 liters.

Not relevant to the question, but just incase, by looking at 225 liters being in the tank, we know that it's been 15 minutes before the sensors started working.

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
