Answer:
15 inches
Step-by-step explanation:
Volume of a pyramid = 1/3 x ( length² x height)
4500 = 1/3 x ( length² x height)
height = 1/2 x length
4500 = 1/3 x ( length² x 1/2length)
multiply both sides of the equation by 6
27000 = ( length² x length)
find the cube root of 27300
length = 30
height = 1/2 x 30 = 15in
Answer:
76
Step-by-step explanation:
Use the equation of motion under gravity:-
s = 16t^2 where s is the distance and t = time
2063 = 16t^2
t^2 = 2063 / 16 = 128.94 s
t = sqrt 128.94 = 11. 4 seconds to the nearest tenth of a second
1)y=3x
2)y=x
3)y=7x
4)y=x+7
4)y=2x+1
6)y=12x+2
