42.5% of what = 20.57

<span>42.5% of x = 20.57
</span>
(42.5/100)*x = 20.57

42.5x / 100 = 20.57

x = 20.57 * 100 / 42.5

x = 48.4

Therefore 42.5% of 48.4 is 20.57.

Equilateral triangle ABC has a perimeter of 96 millimeters. A perpendicular bisector is drawn from angle A to side BC at point M

a_sh-v [17]

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.
