Q1: (NS.3) A scientist measures the change in the temperature of the chemical solution. At the start of the experiment the solution is at the temperature of -14.96 degrees celsius. The temperature decrease 2.9 degrees celsius each hour. Which expression can be used to find the temperature of the solution after 3 hrs? Q2: With expression you chose in Q1, solve after 3 hrs. Round your answer to the nearest whole degree.​

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
