When a teacher gives a test with questions that fall into 3 levels of difficulty (easy, moderate, and hard) The scoring method that would best allow her to identify the students who need help is:
B. weight each question by its difficulty: 1 for easy, 2 for moderate, and 3 for hard.
The answer is C because 1/8 equals 2/4 and she needs 3/4
Answer:
30°
Step-by-step explanation:
Let the measure of the missing angle be x°
Therefore, by interior angle sum postulate of a triangle:
x + 60° + 90° = 180°
x + 150° = 180°
x = 180° - 150°
x = 30°
Thus the measure of the missing angle is 30°.
1 sandwich cut into 8 pieces then eats 1 pieces,
then had 7/8 lefts means that 7 pieces left, if he put each mean put 1 pieces in a plate, than he need 7 plates.
When he ate 1 piece, it means that he ate 1/8 or 1 out of 8 pieces.
he put 1/8 part of the sandwich on each plate.
