Answer:
y = -1/4x-6
Step-by-step explanation:
y=mx+b
Use slope equation m = (y1 - y2) / (x1 - x2)
b is the y intercept : -6
Answer:
The mean of Planted Society's donations received is higher than Bees Park Expansion's.
Step-by-step explanation:
To get the mean, you want to add all of the numbers up and divide by how many numbers up. For example, you add all of the values for Planted Society and get 140. We know that there are 7 numbers given, so we do 140 divided by 7 to get a mean of 20. Same with Bees Park Expansion; add to get a total of 152. There are 8 numbers, and 152 divided by 8 is 19. This means 20>19. Mean is also written as average in questions.
Answer:
2) 12,000 ft²
3) 30 gallons.
Step-by-step explanation:
2) 1. You can calculate the lateral surface area of the exterior walls of the warehouse by applying the formula shown below:
Where <em>h</em> is the height, <em>l</em> is the lenght and <em>w</em> is the width.
2. Substitute values and you obtain that the lateral area is:
![LA=20ft[(2*200ft)+(2*100ft)]](https://tex.z-dn.net/?f=LA%3D20ft%5B%282%2A200ft%29%2B%282%2A100ft%29%5D)
3) You know that 1 gallon of paint covers 400 ft², therefore for 12,000 ft² are needed the following number of gallons (which is represented by <em>x</em>):
you have to add 2×3 =6 ft to both length and width.
33+6 =39
36 +6=45
the perimeter is
p = 2×39 + 2×45
p = 78 + 90
p = 168
Jose needs 168 ft of fencing
