Answer:
40,000
Step-by-step explanation:
--------------------------------------------------
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
--------------------------------------------------
4+3(x+2)=-8
4+3x+6=-8
10+3x=-8
-10 -10
3x= -18
X= -6
Answer:
p=300 and l=15.75
Step-by-step explanation:
H = 45 - 35sin (2 pi T/3)
H = rider's height above the ground, in feet
T = time since the ride started, in minutes.
Note:
The first time the ride stops to take passengers on or let them off, the equation crumbles.
