Which figure best demonstrates the setup for the box method of finding the area of a triangle
Ivanshal [37]
Hi there! The third option shows us the best setup.

We can find the area of a triangle with the standard formula area = 1/2 * base * height.

To be able to fill in this formula, we need to have a base and a height. We can't easily find a triangle with given base and height, so we must look for another option.

We can also take the area of a square (length × width) and then divide the answer by 2. This is possible when we take the third setup. Hence the third answer is correct.

Which one is it I’m super confused...
NARA [144]

Answer:

( x-2)^2 +(y-5)^2 = 12.25

Step-by-step explanation:

The equation of a circle is given by

(x-h) ^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

( x-2)^2 +(y-5)^2 = (3.5)^2

( x-2)^2 +(y-5)^2 = 12.25

Easy Question, Easy points<br><br><br>Topic: Volume<br><br><br>Focus on question 12
anyanavicka [17]

Answer: 0.6 meters cubed.

Step-by-step explanation:

To find the answer to this, first find the volume of the cube.

Volume is equal to the side cubed. In this case, 1 cubed is 1, so the area of the cube is 1 meter cubed.

The depth of the water is 0.4 meters, so the water makes a shape of a rectangular prism, where the length and width are 1 meter, and the height is 0.4 meters.

The volume of a rectangular prism is l*w*h, so the volume of this rectangular prism is 0.4 * 1 * 1, or 0.4 meters cubed.

As such, the volume of the air in the tank is 1 - 0.4, or 0.6 meters cubed.
