The density would be 1560.7 lb/cu ft.
Answer:
(-1,-4)
Step-by-step explanation:
6m-5n=14 equation 1
2m+2n= -10 equation 2
using equation 2 we have
2m=-10-2n
m=-5-n equation 3
using equation 1 we have
6*(-5-n)-5n=14
-30-6n-5n=14
-11n=14+30
-11n=44
n=-44/11
n=-4
using equation 3
m=-5-n
m=-5-(-4)
m=-1
finally we have
(-1,-4)
Answer:
Surface area of what?
You can ask the question again but also add the pic so that we can help :)
Step-by-step explanation:
Data:
circumference=?

There are 680 combinations of four teachers include Mrs. Vera(only)
<h3>How to determine the number of combination?</h3>
The given parameters are
Teachers, n = 18
Selected teachers. r = 4
The selection must include Mrs. Vera.
So, the remaining parameters are:
Teachers, n = 17
Selected teachers. r = 3
The combination is then calculated as:
Ways = nCr
This gives
Ways = 17C3
Apply the combination formula
Ways = 17!/(14!3!)
Evaluate the expression
Ways = 680
Hence, there are 680 combinations of four teachers include Mrs. Vera(only)
