340.8 will be the answer i know how to do surface area of a pyramid but this one is a little confusing i followed the formula and all that but i think this is the right answer, sorry if it was wrong
Answer:
7 -1 6 | -8
7 -5 7 | 1
0 1 -4 | -5
Step-by-step explanation:
Note that there are four columns in this system, representing the variables x, y and z and constants. So the given matrix pattern is appropriate: It has three columns for the coefficients of x, y and z and one column for the constants.
We need only identify the coefficients and transfer them into the appropriate boxes of the matrix pattern.
We get:
7 -1 6 -8
7 -5 7 1
0 1 -4 -5
Answer:
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
Step-by-step explanation:
Given that,
The number of phone calls between two cities (N )
- directly proportional as the value of populations
and 
of two cities. - Inversely varies as the magnitude of distance (d).
Given that,
N=18,000, d=310 miles, =15,500 and =180,000
Now,
N=? , d=435 miles, =100,500 and =160,000
∴73,563 calls are made between two cities with populations of 100,000 and 160,000 that are 435 miles apart.
