So. hmmmm notice the first picture, that's a rectangular prism
is really just 6 rectangles stacked up to each other at the edges
now, notice the second picture, is a prism/shelf with a length of 48, width of 12 and height of 1
so, your shelf is really just 6 rectangles stacked up to each other at the edges
you have 2 rectangles of 48x1 on the sides
2 rectangles of 12x1 for the front and back
and 2 rectangles of 12x48, for the top and bottom
get the area of each of those rectangles, add them up, and that's the surface area of the shelf
Answer:
No solution
Step-by-step explanation:
y = 2x + 4 (1)
-2x + y = -5 (2)
Rewrite equation (2)
y = 2x - 5
So now you have 2 equations
y = 2x + 4 (1)
y = 2x - 5 (2)
----------------------------------Subtract
0 = 9
As you know 0 is not equal 9
Answer: No solution
Answer:
y=-1/2x+17
Step-by-step explanation:
y=-1/2x+17
Answer:
2
Step-by-step explanation:
To evaluate the expression substitute t = 4 into the expression, that is
8/t = 8/4 =2
Answer:
155 km
Step-by-step explanation:
As shown:
At Δ BDC which is a right triangle at ∠D
BC = 78 km
m∠CBD = 90° - 64° = 26°
cos ∠CBD = BD/BC
∴ BD = BC * cos ∠CBD = 78 * cos 26° = 70.106 km
Port C is at a distace to the east of A = AO + BD
= 85 + 70.106 = 155.106 km ≈ 155 km to the nearest km
