Price / weight = unit price
product A : 1.36 / 8 = 0.17 per oz
product B : 3.20 / 16 = 0.20 per oz
product A has the lower unit price
If you multiply by three twice, you're multiplying by six once
Based on the radius of the being 4 units and the area of the equilateral triangle, the area of the shaded area is 32.85 units².
<h3>What is the area of the shaded area?</h3>
First, find the area of the triangle.
The center of a triangle divides the median into a 2:1 ratio which means that the radius can be found as:
Radius = 1/3 x Area of Equilateral triangle
4 = 1/3 x (√3/ 2)a
a can be worked out to be:
= 8√3
The area of the triangle is:
= (√3 / 4) x a²
= (√3 / 4) x (8√3 )²
= 83.14 units ²
The area of the circle is:
= π x radius²
= 22/7 x 4 x 4
= 50.29 units²
The area of the shaded area is therefore:
= 83.14 - 50.29
= 32.85 units²
In conclusion, the area of the shaded area is 32.85 units².

Step-by-step explanation:
$105 - $30 = $75
$75 ÷ $25 = 3 hours
Answer:
<h2> 22.2</h2>
Step-by-step explanation:
Step one
given the coordinates
ABCD with vertices A(-2,-2), B(-1,3), C(5, 3), and D(4, -2)
AB=(-2,-2),(-1,3)
BC=(-1,3), (5, 3)
CD=(5, 3),(4, -2)
DA=(4, -2),(-2,-2)
The distance between points AB=
The distance between points BC=
The distance between points CD
The distance between points DA
Hence the perimeter = 5.1+6+5.1+6
= 22.2
