Answer:
The percentage rate is 4.5%.
Step-by-step explanation:
The given formula for simple interest is I=prt where I=simple interest, p=principle, r = percentage rate and t=time. In the problem, we are told that after six years (t=6), $7000 (p=7000) earns $1890 (I=1890). We can then substitute in the values for three of our variable to get the following: 1890 = (7000)(6)r. Multiplying 7000x6 = 42000 giving us 1890 = 42000r. Using inverse operations, we divide both sides of the equation by 42000 to get 0.045 = r. Since r = percentage rate, we need to multiply our decimal by 100 to find the percentage. 0.045 x 100 = 4.5%.
The answer to your question is 0.008
Answer:
1 3/8 Feet
Step-by-step explanation:
Take 2 1/2 and subtract 1 1/8 which gives u 1 3/8
if u don't understand fractions u can always turn ur fractions into decimals that's what I did :)
Hope this isn't too confusing
Answer:
y-2 = -(x-2)
Step-by-step explanation:
To find the slope
m = (y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are two points on the line
= (1-3)/(4-2)
=-2/2
=-1
The point slope form is
y-y1 = m(x-x1) wher m is the slope and (x1,y1) is a point on the line
y-3 = -1(x-2)
y-2 = -(x-2)
