Answer:
Top Left: you don't really need to pay attention to the ratios. They said it was a right triangle so one of the angles is 90º. The sum of all of the angles in a triangle added together is 180º. We already have the smallest angle so we can add 35 + 90 = 125º. Then subtract is from 180º to get the final angle: 180 - 125 = 55º
If we go by the ratio to determine the largest and smallest number then your answer is: A: 35º B: 90º C: 55º
Middle Left: We know the ration from boys to girls is 11:9 and that there are 124 more boys than girls. First we subtract 11 - 9 = 2 and then we divide 124 by 2 since now we know that 2 is the difference and that the difference in boys to girls in 124 so by dividing by two we can then multiply that number times 11 to find the number of boys and then multiply it by 9 to find the number of girls and then add them together to get the total number of students: 124/2 = 62 62 x 11 = 682 62 x 9 = 558 682 + 558 = 1240 students
Bottom Left: This is hard to explain so I will just give you the answer: a) Triangular Prism b) Rectangular Prism
Top Middle: a) Trapezoid b) 6 (think about it like a 6-sided die)
Middle Middle: a) 8 b) 6 (same as the other answer) c) 12
