Answer:
16 mm
Step-by-step explanation:
Since ABC is an equilateral triangle, all three sides are the same length. The perimeter is found by adding together all of these equal sides; letting x represent the length of a side of the triangle, this gives us
x + x + x = 96
Combining like terms,
3x = 96
Dividing both sides by 3,
3x/3 = 96/3
x = 32
Since AM is a perpendicular bisector, it splits BC into two congruent sections. This means the length of MC, half of BC, will be 32/2 = 16.
Answer:
26) 5 : 11 (simplify it down by 2)
27) 19 : 17 (can't simplify it down)
28) 25 miles per hour (divide 75 by 3)
29) 15 : 24 (subtract 9 from 24 that would leave the amount of students left)
