The elevations, in miles, of three museums are marked on the number line below. Point O on the number line represents sea level. Which of the following statements is true? * A. Museum A is at sea level and both museums B and C are above sea level.
B. Museum A is above sea level and Museum B is at sea level.
C. Both museums B and C are below sea level.
D. Museums A and B are below sea level.

I would say C.

Step-by-step explanation:

Point A would be exactly at sea level while B and C are both under A

(sea level).

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.

step-by-step explanation:

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.
