Answer:
V = 115.3 ft³
Step-by-step explanation:
The left part of the figure shows a cube of side length 4.2 ft. The volume of a cube is V = s³, where s is the side length. Hence, the volume of this particular cube is V = (4.2 ft)³ = 74.088.
The volume of a pyramid is V = (1/3)(base area)(height).
Here V = (1/3)(4.2 ft)²(7 ft) = 41.16 ft³.
Summing up the two distinct areas, we get V = 41.16 ft³ + 74.088 ft³, or
V = 115.3 ft³ after rounding up to the nearest tenth.
2x - 3 < 11 or 8x -10 < 82: <span>X < 23/2

Part 1</span>
</span>2x-3<11
Add 3 both sides
2x-3+3<11+3
Refine
2x<14
Divide by 2 on both sides
2x / 2 / 14 / 2
Refine
x < 7

Part 2</span>
8x-10<82
Add 10 to both sides
8x-10+10<82+10
Refine
8x<92
Divide by 8
8x / 8 / 92 / 8
Refine
x < 23 / 2
The line would intersect with the y-axis at (0,0)
Answer:
it's after 10pm, so will I still get brainliest?
3x + 4x +5x = 54 (because the perimeter = sum of its dies)
12x = 54
x = 4.5
So the 3 sides are 3*4.5 , 4*4.5 and 5*4.5
= 13.5, 18 and 22.5 units (answer)
