Given that 16 ounces equals 1 pound, how many ounces are in 12.4 pounds?
2 answers:
For this case we must find the number of ounces that there are in 12.4 pounds, if we have as data that 16 ounces represent 1 pound, then we can make a rule of three of the form:
16 ounces -----------> 1 pound
x ----------------------> 12.4 pounds
Where "x" represents the number of ounces in 12.4 pounds. So, we have:
So, in 12.4 pounds there are 198.4 ounces
Answer:
198.4 ounces

Answer:
the slope of line j is -1/8, the slope of lines m and n are both 8.
Explanation step by step:
Suppose j is the slope of line j, m the slope of line m and n the slope of line n. Since:
1. line j is perpendicular of line m, so j*m= -1
2. J is perpendicular of line n, so j*n=-1
3. m and n and parallel so m=n
As we want to know the slope of j we clear the equations presented to us in order to find it.
(1) m* n* j = -8, since n=m we have * j = -8.
we clear j;
replacing in the equation n*j = -1 we get
n*(-8/n^2) = -1. Thus n = 8. Since j = -1/n = -1/8.
