Answer:
Perpendicular Bisector Equation: y = 12x - 9.500
Step-by-step explanation:
Let find out the midpoint for given coordinates as follows:
[(-5+7)/2, (3 +2)/2]
= (2/2, 5/2)
= (1,5/2)
The midpoint coordinates are (1,5/2) means (x1 , y2)
2. Find the slop of line for given coordinates as follows:
(2-3)/(7-(-5)
= -1/12
3. Find the negative reciprocal as follows
-1/12
= 12 (m)
4. Now find the perpendicular bisector equation as follows:
y – y1 = m ( x – x1)
y – 3 = 12 (x – (-5)
y = 12x - 9.5
Answer:
1/4
Explanation:
1/2 is 0.5 and 1/4 is 0.25 which is less than 0.5.

a. Chocolate need to cover a rectangle with a length of 9 in. and a perimeter of 22 inches is 18 pieces of 1 inch square piece chocolates
b.Chocolate need to cover a rectangle with a length of 5 in. and a perimeter of 20 inches is 20 pieces of 1 inch square piece chocolates
Step-by-step explanation
a. To cover a rectangle with a length of 9 in. and a perimeter of 22 in.
perimeter = 2(length+breadth)
Breadth = 22 -9×2 = 22-18 = 4 ÷ 2 = 2 inches
Area of rectangle = 9 × 2 = 18 inches
18 pieces of 1 inch square piece Chocolate is needed to cover the rectangle
b. To cover a rectangle with a length of 5 in. and a perimeter of 20 in.
perimeter = 2(length+breadth)
Breadth = 20 - 5 ×2 = 10 = 10 ÷ 2 = 5 inches
Area of rectangle = 5 × 5 = 20 inches
20 pieces of 1 inch square piece Chocolate is needed to cover the rectangle
