To find an equivalent, divide 4 acres by .6 acres= 6.666... then divide the cost of 4 acres ($520 by 6.666....= $78) So it would cost 78 dollars to plant .6 acres of corn.
Answer:
45°
Step-by-step explanation:
Because every angle in a square is 90° and the diagonal is bisecting the angle so we have 45°

Brandon. He earns $25 per lawn, while Adam only earns $20 per lawn
First, we need to get the slope of the equation of the train tracks. We can transform the given equation into the slope-intercept form.
4x +2y = 16
y = -2x +8
The slope of the equation is -2.
A perpendicular line will have the same slope but the opposite sign.
So, the slope of the line of the train crossing is 2. Since, it will pass through the point (8,15), the slope-intercept form can also be used to solve for the equation.
y = mx + b
The slope is 2, so m=2. We solve b by substituting the coordinates.
15 = 2(8) +b
b = -11
The equation is now,
y = -2x - 11
Or it can also be expresses as:
2x - y = 11
