Answer:
96 liters
Step-by-step explanation:
Two liters are in each bottle, so that means they sold 12 bottles of oil each day. Multiply that with 8 days to get the answer:
12 × 8 = 96
Ninety-six liters.
Answer:

Rotatation could be done to left or right.
110 + 60 = 170 degrees => Rotation to the right side.
110 - 60 = 50 degrees= > Rotation to the left side.
We can see in the choices that 170 degrees is the right choice.
The answer is D.
Answer:
--- of perimeters
--- of areas
Step-by-step explanation:
Given
Represent the sides of the first triangle with x, y and z
The sides of the second triangle will be 6x, 6y and 6z
Solving (a): Ratio of perimeter.
The perimeter of the first is:
![P_1 = x + y + z](https://tex.z-dn.net/?f=P_1%20%3D%20x%20%2B%20y%20%2B%20z)
The perimeter of the second is:
![P_2 = 6x +6 y + 6z](https://tex.z-dn.net/?f=P_2%20%3D%206x%20%2B6%20y%20%2B%206z)
Factorize:
![P_2 = 6(x +y + z)](https://tex.z-dn.net/?f=P_2%20%3D%206%28x%20%2By%20%2B%20z%29)
The ratio is:
![R = P_1 : P_2](https://tex.z-dn.net/?f=R%20%3D%20P_1%20%3A%20P_2)
![R = x + y + z : 6(x + y + z)](https://tex.z-dn.net/?f=R%20%3D%20x%20%2B%20y%20%2B%20z%20%3A%206%28x%20%2B%20y%20%2B%20z%29)
Cancel out x + y + z
![Ratio = 1 : 6](https://tex.z-dn.net/?f=Ratio%20%3D%201%20%3A%206)
Solving (a): Ratio of Areas.
If the height of the first is h and the base is b.
The height of the second will be 6h and the base, 6b.
The area of the first is:
![A_1 = 0.5 * b * h](https://tex.z-dn.net/?f=A_1%20%3D%200.5%20%2A%20b%20%2A%20h)
![A_1 = 0.5bh](https://tex.z-dn.net/?f=A_1%20%3D%200.5bh)
The area of the second is:
![A_2 = 0.5 * 6b * 6h](https://tex.z-dn.net/?f=A_2%20%3D%200.5%20%2A%206b%20%2A%206h)
![A_2 = 18b h](https://tex.z-dn.net/?f=A_2%20%3D%2018b%20h)
The ratio is:
![Ratio = A_1 : A_2](https://tex.z-dn.net/?f=Ratio%20%3D%20A_1%20%3A%20A_2)
![Ratio = 0.5bh : 18bh](https://tex.z-dn.net/?f=Ratio%20%3D%200.5bh%20%3A%2018bh)
Divide by 0.5bh
![Ratio = 1: 36](https://tex.z-dn.net/?f=Ratio%20%3D%201%3A%2036)
