29.99 * 55\100 = 16.49 $
29.99 - 16.49 = 13.5 $
Answer:
7x^2 -7x +3
Step-by-step explanation:
The synthetic division of the volume by the height is shown below.
(7x^3 -4x +3)/(x +1) = 7x^2 -7x +3
The area of the bottom face is 7x^2 -7x +3.
Answer:
31.5
Step-by-step explanation:
let x = bars that jamie gets
x + x + 8 = 55
2x = 47
x = 23.5
Tyler = 23.5 + 8
= 31.5
therefore tyler gets 31.5 bars
Answer:
Step-by-step explanation:
Volume of water in the swimming pool
= 25 x 11 x 3.1
= 852.5 m³
mass of water in the pool
= volume x density of water
m = 852.5 x 10³ kg
We shall consider the height H by which the centre of mass of the water-body is increased to lift the water .
H = 3.1 / 2 = 1.55 m
Work done in pumping the water out of pool
mgH ,
= 852.5 x 10³ x 9.8 x 1.55
= 13 x 10⁶ J
