The scale of the drawing is 1 cm to 10 feet. This means, every 1 cm of the drawing represents 10 feet in actual.
The trees are 5.2 cm apart in the drawing. So according to the given scale, they will be 5.2 x 10 = 52 feet apart in actual.
So actual bushes be planted at a distance of 52 feet.
Answer:
First box: y/x = 38/2 = 19
Second box: y/x = 57/3 = 19
Third box: y/x = 76/4 = 19
Constant of proportionality = 19
Equation: y = 19x

Answer:
Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%.
Step-by-step explanation:
Given that Elena receives $ 131 per year in simple interest from three investments totaling $ 3000, and part is invested at 3%, part at 4% and part at 5%, and there is $ 1000 more invested at 5% than at 4%, to find the amount invested at each rate, the following calculations must be performed:
1500 x 0.05 + 500 x 0.04 + 1000 x 0.03 = 75 + 20 + 30 = 125
1600 x 0.05 + 600 x 0.04 + 800 x 0.03 = 80 + 24 + 24 = 128
1700 x 0.05 + 700 x 0.04 + 600 x 0.03 = 85 + 28 + 18 = 131
Therefore, Elena invested $ 1,700 at 5%, $ 700 at 4%, and $ 600 at 3%
