The ratio 3:4 can be written as 3/4
you will then be looking for three quarters of the origional price to get the sale price.
so: 3/4×64=192/4
=$48

Answer:
5/7
Step-by-step explanation:
You find a slope by using the equation y2-y1/x2-x1.
In this case: 15-5/21-7
10/14

Answer:
- perimeter: 42 units
- area: 73.5√3 ≈ 127.3 square units
Step-by-step explanation:
The side length of the hexagon is equal to its radius: 7. The perimeter is 6 side lengths, so is
perimeter = 6·7 = 42 . . . units
__
The area is half the product of the perimeter and the apothem. The apothem is cos(30°) = (√3)/2 times the side length, so is (7√3)/2.
A = 1/2·perimeter·apothem
area = (1/2)(42)(7√3)/2 = 73.5√3 . . . square units
