Answer:106
Step-by-step explanation:
Let number of white marbles be w
Let number of red marbles be r
w+r = 126---------1
w = 6 +5r-----------2
Put eqn 2 in eqn 1
6+ 5r + r = 126
6 + 6r = 126
6r = 120
r = 20
w = 6 +5r =6+100
= 106
Answer: 38 feet.
Step-by-step explanation:
The equation of motion of a body thrown vertically upwards:
,

Substitute in formula (1) the value t=2 c:

Answer:
Option (A)
Step-by-step explanation:
Volume of a cylinder is given by the formula,
V = πr²h
Here r = radius of the cylinder
h = height of the cylinder
Therefore, volume of a cylinder given in the question,
V = π(
)²(8)
= 648π
= 2035.8 km²
Volume of the given cylinder is 2035.8 km².
Option (A) will be the answer.
The equation of a circle with centre (a,b) and radius r is:
(x - a)^2 + (y - b)^2 = r^2
thus,
here centre (a,b) = (-3,6), a = -3, b = 6
and radius = diameter/2 = 20/2 =10 units
therefore, the equation is
(x + 3)^2 + (y - 6)^2 = 100
which is c.
