Answer:
9
Step-by-step explanation:
Fractions are basically glorified division.
Numerator gets divided by denominator.
2 / 5 = 0.4

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.
Answer:
$2410.26
Step-by-step explanation:
principal, p=$2250
rate, r=3.5%
interest, i at the beginning of 1st year = p*r=2250*3.5/100
i=$78.75
amount at the end of 1st year = 2250+78.75=$2328.75
interest at the beginning of 2nd year = 2328.75*3.5/100
i=$81.50625
amount at the end of 2nd year=2328.75+81.50625
=$2410.26
