Answer:
sum was 300000
Step-by-step explanation:
let sum of money is placed is x rs
Term T = 3 years, rate R = 10%
Then simple interest for for 3 years is

Sum of x will become x+0.3x = 1.3x after 3 years. now this 1.3x is kept for compound interest for two years. ie
![A =P[1+R]^t\\471900=1.3x[1+\frac{10}{100} ]^2\\x=\frac{471900}{1.573} \\x=300000](https://tex.z-dn.net/?f=A%20%3DP%5B1%2BR%5D%5Et%5C%5C471900%3D1.3x%5B1%2B%5Cfrac%7B10%7D%7B100%7D%20%5D%5E2%5C%5Cx%3D%5Cfrac%7B471900%7D%7B1.573%7D%20%5C%5Cx%3D300000)
Sum was 300000
Let the speed of the current be y and the speed of Micah's sailing speed be x. Then 4.48/(x + y) = 0.32
4.48/(x - y) = 0.56
0.32x + 0.32y = 4.48 . . . (1)
0.56x - 0.56y = 4.48 . . . (2)
(1) x 7 => 2.24x + 2.24y = 31.36 . . . (3)
(2) x 4 => 2.24x - 2.24y = 17.92 . . . (4)
(3) - (4) => 4.48y = 13.44
y = 3
From (1), 0.32x + 0.32(3) = 4.48
0.32x = 4.48 - 0.96 = 3.52
x = 3.52/0.32 = 11
Therefore, the speed of the current is 3 miles per hour.
Answer:
-2(1.5h + 5) - 4(-0.5 + 3h) = -15h-8
Step-by-step explanation:
-2(1.5h + 5) - 4(-0.5 + 3h)
-2*(1.5h)+(-2*5)-(4*-0.5)-4(3h)
-3h-10-(-2)-12h
-3h-12h-10+2
-15h-8
This is because (1/3) = (2/6). 10 copies of (1/6) = (10/6) and 5 copies of (2/6) = (10/6) too. (1/3) is just the most simplified form for (2/6)
