Answer:
The slope is -3/2
Step-by-step explanation:
<u>A line that is perpendicular to another has the slope that has the sign reversed and is the reciprocal.
</u>
Example: Find the line perpendicular to y = 3x
First, you flip the sign which makes 3 into -3
Next, you make the reciprocal which makes -3 into <u>-1/3
</u>
Problem: Find the line perpendicular to y = (2/3)x + 7
First, you flip the sign which makes 2/3 into -2/3
Next, you make the reciprocal which makes -2/3 into <u>-3/2</u>
Answer: The slope is -3/2

So, imagine the trainer is in the very middle of the circle and he is holding out a rope that's attached to the horse. The rope here from the trainer to the horse represents the radius of the circle. The horse trots around the trainer (middle point) in a circle.
The formula to find area of a circle is A = pi*r^2 (pi times r squared where r is radius)
We know that the radius of the "circle" here formed as the horse trots around the trainer is 31 (the 31 foot long rope).
So let r = 31 & plug the value into the formula to find circle area.
A = pi*31^2 = 3019.07054
The area is therefore 3019.07 square feet. (rounded)
Answer:
The cost of the sweater before the markup is $24.50.
Step-by-step explanation:
The percent markup of an item is calculated by subtracting the original cost of the item from the sale price and then dividing by the original cost. In this case, we are trying to find the original cost, so we know that the percent markup is 40%, or 0.4. Since the sale price of the item would be 100% of the original cost multiplied by an additional 40% markup, we can take the sale price of the item divided by 140%, or 1.4: 34.30/1.4 = 24.50.
