Answer:
The volume of a bar of gold with a mass of 66.5 grams is 
Step-by-step explanation:
Given , mass(in grams) ∝ Volume (in cm3)
Here, volume of 95 grams bar = 5cm3
So, thevolume of 1 gram bar =
= 
⇒The volume of a bar with weight 66.5 grams = 
So, the volume of a bar of gold with a mass of 66.5 grams is 
Answer:
5 - 20/0.10 =
Step-by-step explain
20-5 = 15
15/0.10 = 150
150 = 2h and 30min
so he has to use 2h/30min on the phone
Answer:
The distance between the points is 9.219544457292887
Step-by-step explanation:
Given:
A parabola opens up or down and its vertex is at the point (h, v).
To find:
The equation of the parabola.
Solution:
A parabola opens up or down. It means it is a vertical parabola.
The vertex form of a vertical parabola is
...(i)
Where, a is constant and (h,k) is vertex.
The vertex of given parabola is at point (h,v). Putting h=h and k=v in (i), we get

The required equation of the parabola is
.
Therefore, the correct option is A.
