the slope is m = 0.4
Step-by-step explanation:
use symbolab I use it all the time it gives correct answer and is gives good explanations (this isn't a sponser I've just been using it since the 6th grade lol)
Answer:
Trapezoid
Step-by-step explanation:
To find the shape of the quadrilateral given by the coordinates, we have to find the length of the sides first. The length between two side O(x1, y1) and P(x2, y2) is given as:
![OP=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2`} \\](https://tex.z-dn.net/?f=OP%3D%5Csqrt%7B%28x_2-x_1%29%5E2%2B%28y_2-y_1%29%5E2%60%7D%20%5C%5C)
Therefore the length of the sides are:
![AB=\sqrt{(6-8)^2+(0-4)^2}=\sqrt{20}\\BC = \sqrt{(3-6)^2+(2-0)^2}=\sqrt{13}\\ CD=\sqrt{(7-3)^2+(10-2)^2}=\sqrt{80}\\ AD=\sqrt{(7-8)^2+(10-4)^2}=\sqrt{37}](https://tex.z-dn.net/?f=AB%3D%5Csqrt%7B%286-8%29%5E2%2B%280-4%29%5E2%7D%3D%5Csqrt%7B20%7D%5C%5CBC%20%3D%20%5Csqrt%7B%283-6%29%5E2%2B%282-0%29%5E2%7D%3D%5Csqrt%7B13%7D%5C%5C%20CD%3D%5Csqrt%7B%287-3%29%5E2%2B%2810-2%29%5E2%7D%3D%5Csqrt%7B80%7D%5C%5C%20AD%3D%5Csqrt%7B%287-8%29%5E2%2B%2810-4%29%5E2%7D%3D%5Csqrt%7B37%7D)
Since all the sides are not equal, it is a trapezoid. In a trapezoid all the sides must not be equal
Answer: 4d -3
Step-by-step explanation:
1. 2/6
2. 1/4
3. 7/80
4. 4/15
5. 2/18
6. 2/20
7. 63/2,646
2 seperate questions
what is the weight of 1 gallon and what is the cost per gallon
weight/1gallon=wieght/gallons=129.8lb/22gal=5.9lb/1gal
weigth is 5.9lb per gallon
cost per gallon=cost/gallons=$91.30/22gal=$4.15/1gal
cost is $4.15 per gallon
if ya wanted to estimate
lb per gallon is 129.8lb/22gal≈130/20=6.5lb/gal=6.5lb per gal
cost is $91.30/22gal ≈90/20=9/2=$4.50 per gal
