Rate=100 * Simple Interest
Rate= 100*3x*4 divided by x*8*25
Rate=6%
We are given that 14 inch represent 38 foot.
To know the model length that represents 1 foot, all we have to do is cross multiplication as follows:
14 inch ..............> 38 foot
?? inch .............> 1 foot
length on model = (1*14) / 38
length on model = 7/19 inch = 0.36842 inch
Perpendicular lines have slopes that are negative reciprocals to each other, that is, if one slope is a/b, the other is -b/a
in this case, the given slope is 1/3, so the other line's slope is -3/1, which is -3
from the graph we see that the y intercept of line b is -4, so the equation of line b is: y=-3x-4
It’s unsolvable with out more context. What’s the rest of the problem.
