Answer:
100000
Step-by-step explanation:
The smallest 6 digit number is 100000
Answer:
x = 10
Step-by-step explanation:
The total length of segment PS is 52. To solve for x, we can simply add 5x (which is the length of segment PR) and x-8 (which is the length of segment RS) together and make the equation equal to 52 to solve for x.
- 5x+x-8 = 52
- 6x - 8 = 52
- 6x = 60
- x = 10
Answer:
The brother would be 13
Step-by-step explanation:
14 - 6= 8
There's an 8-year difference
21 - 8= 13

Surface area of the cube
--------------------------------------------------
6(2.5 x 2.5) = 37.5m²
<em>(* Each area is 2.5 x 2.5, and there are 6 sides to the cube)</em>
--------------------------------------------------
Surface area of the rectangle prism
--------------------------------------------------
2(11 x 7) + 2(9 x 7) + 2(9 x 11) = 478m²
<em>(* The opposite side of the rectangle area is the same, therefore x2)
</em>
--------------------------------------------------
Overlapping area
--------------------------------------------------
2.5 x 2.5 = 6.25m²
--------------------------------------------------
Surface area of the composite figure
--------------------------------------------------
37.5 + 478 - 2(6.25) = 503m²
<em>(* The bottom of the cube and the top of the rectangle prism overlapped, so the area is overlapped twice, minus 2 times of that area)</em>
--------------------------------------------------
Answer: 503m²
