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: 120
Step-by-step explanation:
180 - x = 60
-x = -120
x = 120
Answer:
Step-by-step explanation:
y - 1 = 3(x - 4)
y - 1 = 3x - 12
y = 3x - 11
Answer:
After 4 seconds, the ball is at 229 ft
Step-by-step explanation:
Here, we want to get the height of the ball at 4 seconds
What we have to do here is to substitute the value of t for 4 seconds in the equation
We have;
h = -16(4^2) + 121(4) + 1
h = -256 + 484 + 1
h = 229 ft
