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: 1.25n
=======================================================
Explanation:
Erica sells bracelets for $2 each. If she makes and sells n of them, then she gets 2n dollars of revenue.
Making n bracelets cost her a total of 0.75n dollars because each bracelet costs 0.75 dollars, or 75 cents.
Subtract the revenue and cost to get the profit
profit = revenue - cost
profit = 2n - 0.75n
profit = (2-0.75)n
profit = 1.25n
The expression 1.25n means that she earns $1.25 in profit per bracelet sold.
Answer:
3 – i hope i helped :)))))
Step-by-step explanation:
10000x8%= $800 anually
anually=yearly
800x18=14400
Your sloe would be 2/3x because that fraction is rise over run so you go up two and over three positive the -3 is your intercept but he fraction simplified is your slope good luck
