1.) How do you find the area of composite figures?
-A composite figure is made up of simple geometric shapes. To find the area of a composite figure or other irregular-shaped figure, divide it into simple, non overlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.
2.)How do you find the surface area of a figure made up of cubes and prisms?
-The surface area is the area that describes the material that will be used to cover a geometric solid. When we determine the surface areas of a geometric solid we take the sum of the area for each geometric form within the solid.
3.)3. How do you find the volume of a figure made of cubes and prisms?
-To find the volume of a rectangular prism, we multiply the length of the prism by the width ... Practice set 2: Finding volume with unit cubes.
Answer: B) 12
Step-by-step explanation: In order to solve this you have to know the scale factor between the two triangles. In order to do that you just need to take a similar side between the two triangles and divide them. For example:
10 / 15 = .6666
This is RW divided by RT
Now that you have the scale factor, you just need to multiply it by 18 to get WV.
18 x .666666 = 12
Answer:
24 dollars.
Step-by-step explanation:
1/4 + 1/3 = 3/12 + 4/12 = 7/12
7/12 a + 8 = 22
7/12 a = 14
a = 14 x 12/7
a = 24
