In what time a certain sum of money will be 2.5 times at 10% rate of interest

Mathematics
1 answer:
WITCHER [35]3 years ago
5 0

Answer:

Step-by-step explanation:

It takes 15 years to get 2.5 times the sum at 10% p.a.

Let the principal be 'P'.

Let the amount be '2.5P'

Rate = 10%

Amount = Principal - Interest

2.5 P = P - Interest

Interest = 1.5 P

So, we get that

1.5P =\frac{P*R*T}{100} \\1.5 * 100 = 10 * T\\T = 15 years

hope it helps :)

2.5/6 = h/9 h=? What does this mean
omeli [17]

Answer:

h = 3.75

Step-by-step explanation:

Step 1: Write equation

2.5/6 = h/9

Step 2: Solve for <em>h</em>

  1. Cross multiply: 22.5 = 6h
  2. Divide both sides by 6: 3.75 = h
  3. Rewrite: h = 3.75

Step 3: Check

<em>Plug in h to verify it's a solution.</em>

2.5/6 = 3.75/9

Write the equation for a circle with a center at (5,-2) and a radius of 4.
choli [55]

Answer:

(x-5)^2+(y+2)^2=4^2

Step-by-step explanation:

The equation of a circle is: ( x - h )^2 + ( y - k )^2 = r^2 where ( h, k ) is the center and r is the radius. Therefore, the equation in this instance is (x-5)^2+(y+2)^2=4^2.
