The area of all 3 lateral triangular faces will be found by using the formula for area of a triangle.
A = 1/2bh
Face 1:
1/2 x 3 x 5
A = 7.5 square cm
Face 2:
1/2 x 4 x 5
A = 10 square cm
Face 1:
1/2 x 5 x 5
A = 12.5 square cm
12.5 + 7.5 + 10 = 30 square cm
The area of the lateral faces is 30 square cm.
All boys =1
all girls = 1
all boys or all girls = 1/2
The system of equations can be used to determine how much of product x and product y the store owner bought is x + y = 4,000
0.10x + 0.04y = 352
<h3>Simultaneous equation</h3>
- product x
- Product y
- Total units of x and y = 4,000 units
- Cost of shipping each product x = $0.10
- Cost of shipping each product y = $0.04
- Total cost of shipping = $352
The equation:
x + y = 4,000
0.10x + 0.04y = 352
Therefore, the system of equations can be used to determine how much of product x and product y the store owner bought is x + y = 4,000
0.10x + 0.04y = 352
