Answer: volume of pyramid is
100 ft.3
Step-by-step explanation:
The formula for determining the volume of triangular Pyramid is expressed as
Volume = 1/3AH
Where
A represents the area of the triangular base of the pyramid
H represents the height of the pyramid.
The triangular Pyramid has a base of 10 square feet and a height of 30 feet. Therefore,
Volume = 1/3 × 10 × 30 = 100 cubic feet
The answer is <span> B- y=4-1.5x
</span><span>David is rowing a boat upstream, so the river is slowing him down. Thus, the net speed is 6 mph - 2 mph = 4 mph.
Since David's speed </span><span>decreases at a rate of 1.5 miles per hour, after x hours his speed y will be:
y = 4 - 1.5 x</span>
The scale factor is 2 or 200%
U just multiply them. V=A*h=96ft^3
