Step-by-step explanation:

Answer:
49 cm²
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ← s is the length of the side, thus
s³ = 343 ( take the cube root of both sides )
s =
= 7, thus
area of base = s² = 7² = 49 cm²
Answer:
b=7
Step-by-step explanation:
Answer:B
Step-by-step explanation:
if you do A then you are losing 50% of your profit on for items
if you do see then you are giving 40% discount on that item which means you would only get 60% of the one item.
<u><em>Therefore your best bet is B because you still get the price of two items</em></u>
Answer:
Step-by-step explanation:
1) 
= 50 + (-9*8) *1
= 50 - 9.8
= 40.2 m/s
2) The acceleration of the ball at its maximum height equals to the force of gravity. -9.8 m/s²
3) The velocity at its top of the path:When the ball is thrown straight up, its velocity keeps on decreasing due the pull of gravity which pulls it towards the ground. So, the velocity at the top of its path is zero.
