I think it’s triangle four
Answer:
The two companies charge the same for 12 tons of sugar.
Amount charged by each of the company ![=\$8003](https://tex.z-dn.net/?f=%3D%5C%248003)
Step-by-step explanation:
Let x denotes amount of sugar for which the two companies charge the same.
Amount charged by the first company ![=6500+125.25x](https://tex.z-dn.net/?f=%3D6500%2B125.25x)
Amount charged by the second company ![=5897+175.50x](https://tex.z-dn.net/?f=%3D5897%2B175.50x)
To find amount of sugar for which the two companies charge the same,
solve ![6500+125.25x=5897+175.50x](https://tex.z-dn.net/?f=6500%2B125.25x%3D5897%2B175.50x)
![6500+125.25x=5897+175.50x\\6500-5897=175.50x-125.25x\\603=50.25x\\x=\frac{603}{50.25}\\ x=12](https://tex.z-dn.net/?f=6500%2B125.25x%3D5897%2B175.50x%5C%5C6500-5897%3D175.50x-125.25x%5C%5C603%3D50.25x%5C%5Cx%3D%5Cfrac%7B603%7D%7B50.25%7D%5C%5C%20x%3D12)
So, the two companies charge the same for 12 tons of sugar.
Amount charged by the first company ![=6500+125.25(12)=8003](https://tex.z-dn.net/?f=%3D6500%2B125.25%2812%29%3D8003)
Amount charged by the second company ![=5897+175.50(12)=8003](https://tex.z-dn.net/?f=%3D5897%2B175.50%2812%29%3D8003)
Amount charged by each of the company ![=\$8003](https://tex.z-dn.net/?f=%3D%5C%248003)
Find gradient by changing form of equation: y = 2/3x + 4. Gradient is 2/3.
Find y intercept of other line by substituting the coordinates: -8/3
Use information to write out equation of line: y= 2/3x - 8/3
Convert to standard form: -2x + 3y = 8.
Hope this helps :)
No,The room is not a square shaped.This is because.Perimeter of the square shape would be length of any sides×4 as all sides will be the same in a square.Therefore, if the room ia a square, the 4 sides of room floor will be equal too.It is not a square shaped room beacause it sides are not equal for floor.We can determine by finding the sides;
diagonal is 18.75 so by using pythagoras theorem
diagonal^2 =l^2 + b^2
b^2=18.75^2 + 17^2
b =25.31 inches which is not the same as the length 17 inches.Therefore,the room is not a square
