- point a is the top of mount everest which is approximately3964 miles away from the center of the earth. point b is on top of a mountain in china that is 3960 miles away from the center of the earth. using the lines of latitude, there is a 14.9º angle between the two from the center of the earth. how far is the actual distance from one mountain top to the other?
-- 1027 miles
--1923 miles
--2042 miles
-- 5603 miles

1027 miles

Step-by-step explanation:

Using the Law of Cosines, the distance "c" between the mountains can be found from ...

c^2 = a^2 + b^2 -2ab·cos(C)

= 3964^2 +3960^2 -2·3964·3960·cos(14.9°)

≈ 1,055,634.95

So, the distance is about

c ≈ √1055634.95 ≈ 1027.44

The straight-line distance (partially through the Earth) from one mountaintop to the other is about 1027 miles.

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
