Answer:
Charley's class.
Step-by-step explanation:
There are 25 students in Amanda class and 27 in Charley's.
Number of students with no pets in Amanda's = 7 which is 100 * 7/25 = 28%.
In Charley's class this is 8 which is 100 * 8/27 = 29.6%.
They are similar in the way that you have to find the area of the base(s) and then the area of the lateral faces. They are different because there are different formulas used to derive their respective surface areas, and the calculations are a bit different as in a triangular prism, you have to find the area of some triangular faces, while the rectangular prism has all rectangular faces. Additionally, the triangular prism has 5 faces, and the rectangular prism has 6 faces. I hope this helps.
Figure B i imagine is correct
Answer:
x = 6
y = 4
Step-by-step explanation:
x + x - 2 = 10
2x - 2 = 10
2x = 12
x = 6
y = 6 - 2
y = 4
Check the picture below.
so, if we get the whole area of the figure, which will be the combined areas of those three rectangles, and if we get the area of the triangle, and then subtract that area from of the triangle from the whole figure's area, we're in effect making a whole in the total area, and what's leftover is the shaded area.
