Answer:

  • 4 months

Step-by-step explanation:

Let the number of months be x

Alligator 1 weight = 4 + 2x

Alligator 2 weight = 8 + x

  • 4 + 2x = 8 + x
  • 2x - x = 8 - 4
  • x = 4

The answer is 4 months

Hiran invests 20 000 rupees in an account for 3 years at 1.5% per year compound interest.
svp [43]

Answer:

There will be 20 914 rupees in the amount at the end of 3 years.

Step-by-step explanation:

The amount of rupes after t years in compound interest is given by:

A(t) = A(0)(1+r)^{t}

In which A(0) is the initial amount and r is the interest rate, as a decimal.

Hiran invests 20 000 rupees in an account for 3 years at 1.5% per year compound interest.

This means that A(0) = 20000, r = 0.015. So

A(t) = A(0)(1+r)^{t}

A(t) = 20000(1+0.015)^{t}

A(t) = 20000(1.015)^{t}

Work out the total amount of money in the account at the end of 3 years.

This is A(3). So

A(3) = 20000(1.015)^{3} = 20913.6

Rounding to the nearest rupee.

There will be 20 914 rupees in the amount at the end of 3 years.

Can someone help me

Answer:

(2/3)y - (8/3) = x For the first one maybe?


Step-by-step explanation:

1. y = (3/2) x + 4

y - 4 = (3/2) x

(2/3)y - (8/3) = x


2. If output is 2, f(x) = 2.

So, 2 = (3/2) x + 4

-2 = (3/2) x

-4 = 3x

x = -3/4
