Answer:
- small prism: 630 m²
- large prism: 2520 m²
Step-by-step explanation:
The total surface area of the prism is the sum of the base area and the lateral area. The base area is made up of two right triangles, so will be the product of the triangle leg dimensions. The lateral area is made up of three rectangles whose width is that of the prism and whose equivalent length is the perimeter of the triangle base.
For the smaller prism, the area is ...
(20 m)(21 m) +(3 m)(20 m + 21 m + 29 m) = 420 m² +210 m² = 630 m²
The larger prism is similar, with a scale factor of 2, so its area will be 2² = 4 times that of the smaller prism:
4×630 m² = 2520 m²
__
In summary, the total surface area of each prism is ...
- small prism: 630 m²
- large prism: 2520 m²
Answer:
The answer would be 1/6 kids are wearing shirts that are neither blue or white.
Step-by-step explanation:
So, to make this easier, lets convert 2/3 to a same denominator fraction.
We must ask, how many times does 3 go into six?
We multiply 3 by 2 and get six. We then multiply the numerator of 2 by the same, getting 4.
Our new fraction is 4/6 which is equal to 2/3.
Then we add 4 to 1, making it 5. That is the amount of students wearing blue and white shirts, which means
1/6 of the kids in the class are wearing shirts that are neither white nor blue.

The new coordinates are A(-4, 10), B (-4, 12), C (0, 12) and D (0, 10). If you were to connect these, it would take the shape of a rectangle.
The cumcutative property of addition
Answer:
28 sqr feet.
Step-by-step explanation:
Congruent means equal to. So Cold = Warm for some given property (Area in this case).
28 ft^2 is the answer
