  4. THINK READ What is the measure of angle S? Isosceles = 2 sides and 2 angles are the same Angle R = 40 Sum of Angles in Triangle = 180 CHECK The measure of angle S is 70 degrees. I subtract the known angle of 40 degrees from a triangle’s total of 180 to get 140 degrees. Since it is isosceles that means the two angles together equal 140. I divide 140 by two to find that each angle is 70 degrees. SOLVE 180 – 40 = 140 140 ÷ 2 = 70 Check: 70 + 70 + 40 = 180

  5. Bell RingerTuesday • Find the volume of each prism. 4 ft. 2 ft. 10 ft. 10 in. 5 in. 4 in. 5 in.

  8. THINK READ How many hours will he participate over 52 weeks? 8 hrs – sports 5 hrs – drama Over 2 weeks = 13 hours CHECK He will participate a total of 338 hours. He practices 13 hours for 2 weeks. So I divided 52 weeks by 2 to get 26 weeks. If he practices 13 hours every 2 weeks I muliply 13 by 26 to get 338 hours, or the total for 52 weeks. SOLVE 52 weeks / 2 weeks = 26 weeks 13 x 26 = 338 hours

  12. THINK READ About how many songs could be on the CD? CD total = 80 min Each song between 4 and 6 = 5 CHECK The CD could have about 16 songs on it if the total length of the CD is 80 minutes. If each song is about 5 minutes, I divide the total of 80 by 5 to find that it could have about 16 songs. SOLVE 80 min/ 5 min = 16 songs
