. A sample of bacteria was taken from a public restroom sink and was found to be tripling every 30 minutes. If the sample contained 12 bacteria, how many bacteria will be in the sample 4 hours from now? * 4 points 972 bacteria 34 bacteria 78,732 bacteria 3,072 bacteria

78,732 bacteria

Step-by-step explanation:

12 × 3^8 =78,732

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.

5+2x=a
