Answer:
The fence will cost $333.64
Step-by-step explanation:
In order to calculate how much it'll cost to build the fence around his garden we first need to know the length of material he'll need to buy. To do that we must find the length of the circle that surrounds the garden and then multiply by the price of each foot. The length of the circle is given by:
length = 2*pi*r
length = 2*pi*15
length = 30*pi
length = 94.25 feet
The cost of the fence, is:
cost = length*(cost per foot) = 94.25*3.54
cost = 333.64
The fence will cost $333.64
Answer:
![- \frac{1}{4}](https://tex.z-dn.net/?f=%20-%20%20%5Cfrac%7B1%7D%7B4%7D%20)
Step-by-step explanation:
![gradient = \frac{y1 - y2}{x1 - x2}](https://tex.z-dn.net/?f=gradient%20%3D%20%20%5Cfrac%7By1%20-%20y2%7D%7Bx1%20-%20x2%7D%20)
![slope \: of \: line \\ = \frac{1 - ( - 3)}{ - 24 - ( - 8)} \\ = \frac{1 + 3}{8 - 24} \\ = \frac{4}{ - 16} \\ = - \frac{1}{4}](https://tex.z-dn.net/?f=slope%20%5C%3A%20of%20%5C%3A%20line%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%20-%20%28%20-%203%29%7D%7B%20-%2024%20-%20%28%20-%208%29%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B1%20%2B%203%7D%7B8%20-%2024%7D%20%20%5C%5C%20%20%3D%20%20%5Cfrac%7B4%7D%7B%20-%2016%7D%20%20%5C%5C%20%20%3D%20%20-%20%20%5Cfrac%7B1%7D%7B4%7D%20)
So basically it's going to be a n / 2 + 10 less than - 9 so you're just going to Simply use the two to multiply the n, the 10 and the -9 and your answer would be = n is less than -38
Answer:
(a) yes
(b) 104% profit
Step-by-step explanation:
250 apples for $22,500 (were they gold?)
Part 1:
50x$120=$6000
Part 2:
200 sold at $1000 per 5 apples=200/5x1000=$40,000
$40,000+$6000=$46,000
A profit of $23,500
23500/22500=1.044 or 104% profit
