Answer: The answer is 13 ponds of each type should be used.
Step-by-step explanation: Given that the coffee counter charges $11.00 per pound for kenyan french roast coffee and $13.00 per pound for sumatra coffee. We are to find the quantity of each type that should be used to make a 26 pound blend that sells for $12.00 per pound.
Let 'x' pound and 'y' pound of kenyan french roast coffee and sumatra coffee be used in the mixture of 26 pound.
So, we have
Multiplying equation (A) by 11 and subtracting from equation (B), we have
and from equation (A),
Thus, 13 pounds of each type of coffee should be used.
<h2>Given :-</h2>
- Area of Rhombus = Area of Triangle
- Base and Height of Triangle is 24.8 cm and 5.5 cm respectively .
- Length of one diagonal of the rhombus is 22 cm .
- Length of other Diagonal
As we know that
Area of triangle = ½ × Base × Height
- Area = ½ × 24.8 × 5.5
- Area = 1 × 12.4 × 5.5
- Area = 12.4 × 5.5
- Area = 68.2 cm²
Area of rhombus = ½ × D1 × D2
- 68.2 = ½ × 22 × D2
- 68.2 × 2 = 22 × D2
- 136.4 = 22 × D2
- 136.4/22 = D2
- 6.2 = D2
- D2=6.2
