Answer:
30 elementary students
Step-by-step explanation:
There are 13 households with 1 child
There are 11 households with 2 children
There are 4 households with 3 children
There is 1 household with 4 children
There are 0 households with 5 children
There is 1 household with 6 children
There are 0 households with 7 children
Therefore, there's a total of 13+11+4+1+0+1+0=30 elementary students
Answer:
The area of the shape is 122.30 cm^2
Step-by-step explanation:
To calculate the surface area, we identify the side shapes
We have this as;
a rectangle that measures 11 cm by 3 cm, a rectangle that measures 3 cm by 6 cm, a rectangle that measures 8 cm by 3 cm, 2 triangles ( base and top) that has a height of 4.3 cm and a base of 11 cm
The area of the rectangles is simply the product of the side lengths
The area of the triangles is the product of the base and the height divided by 2; but since we have 2 exact triangles, we can simply multiply the base and the height to serve as the area of both
Thus, we have the area of the shape as follows;
(11 * 3) + (3 * 6) + (8 * 3) + (4.3 * 11)
= 33 + 18 * 24 + 47.3
= 122.30 cm^2
Answer:
The coefficient is same and constant is different
