Answer:
The interest is 
Step-by-step explanation:
we know that
The compound interest formula is equal to
where
A is the Final Investment Value
P is the Principal amount of money to be invested
r is the rate of interest in decimal
t is Number of Time Periods
n is the number of times interest is compounded per year
in this problem we have
substitute in the formula above

<em>Find the interest</em>

Answer:
<h3>The lines are perpendicular</h3>
Step-by-step explanation:
We determine whether lines are parallel or perpendicular by getting their slopes
For line 1; (1, 0), (7, 4)
Slope m = 4-0/7-1
M1 = 4/6
M1 = 2/3
Hence the slope of M1 is 2/3
For Line 2; (7, 0) , (3, 6)
M2 = 6-0/3-7
M2 = 6/-4
M2 = -3/2
Take the product of the slopes
M1 * M2 = 2/3 * -3/2
M1M2 = -1
Since the product of their slope is -1, hence the lines are perpendicular
Answer:
JML=126 (x=42)
Step-by-step explanation:
Since the whole angle is equal to 180, you take that and subtract it by the part of that angle you know. The remainder is JML. If you want to find x, you set 3x equal to 126.

Cost of one disc = (cost of that # of discs) / (# of discs)
= $40 / 3 = $13.33 per disc
