Answer:
x= 12
Step-by-step explanation:
Please see attached picture for full solution.
Given parameters:
y varies directly as w;
This interpreted implies that as y increases, we increases by a certain factor or amount;
So, y ∝ w
y = kw
where k is the constant of proportionality
Now, given that y = 8 and w = 2
Input in the equation to solve for k;
8 = k x 2
Solving k gives, k = 4
Now to the second part,
if v is directly proportional to w;
v = k w
So v = 4w
The equation that relates v to w is v = 4w
Volume of a sphere = 4/3(3.14)(2.6)^3
Raise 2.6 to the third power and substitute it in the equation
Multiply that number by 3.14
Whatever your answer is, times it by 4
Then divide that answer by 3
Hope this helps !
Answer:
7.44
Step-by-step explanation:
With reference angle 28°
perpendicular (p) = x
base (b) = 14 cm
Now
Tan 28° = p / b
0.532 = x / 14
x = 7.44
Hope it will help :)
