Answer:

Step-by-step explanation:

The two rectangles are similar. The shapes are the same but the sizes are different. The ratio of the smaller rectangle to the bigger one is constant.

Comparing the sides of the two rectangles, we would take ratio of the width of both rectangles and equate it to ratio of the lengths of both rectangles. It becomes

3/5 : 12 = x : 20

(3/5)/12 = x/20

3/5 × 1/12 = x/20

3/60 = x/20

Cross multiplying

60 × x = 20 × 3

60x = 60

x = 60/60 = 1

The enlargement is in a scale of 5. Multiplying any length on the smaller rectangle by 5 will give the corresponding length of the bigger

Yolanda's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Yolanda $5.20 per pound, and t
MAXImum [283]

Answer:

78 pounds

Step-by-step explanation:

Let's say Yolanda makes a pounds of Type A coffee and b pounds of Type B coffee. Since the total number of pounds is 130, we can write the equation:

a + b = 130

We know the cost of Type A coffee is $5.20/lb and the cost of Type B coffee is $4.05/lb, so since the total cost is $586.30, we can write:

5.20a + 4.05b = 586.30

We can now solve the system of equations:

a + b = 130

5.20a + 4.05b = 586.30

Manipulate the first equation by subtracting b from both sides:

a + b = 130

a = 130 - b

Substitute 130 - b for a in the second equation:

5.20a + 4.05b = 586.30

5.20 * (130 - b) + 4.05b = 586.30

676 - 5.20b + 4.05b = 586.30

Move the terms with b to one side:

1.15b = 89.70

b = 78

Thus, Yolanda used 78 pounds of Type B coffee.
