Answer:

  • interest: $144
  • principal plus interest: $944

Step-by-step explanation:

The amount of interest is found using the simple interest formula. That is added to the principal to find the total account balance.

__

<h3>Interest</h3>

  I = Prt . . . . . P = principal, r = annual rate, t = number of years

  I = $800·0.06·3 = $144

The simple interest earned in 3 years is $144.

__

<h3>Principal plus interest</h3>

Adding that to the principal gives ...

  $800 +144 = $944

The total principal plus interest is $944.

What is the value of n? n–2= 10n+ 4/2 Enter your answer in the box.
pentagon [3]

Answer:

-4 / 9

Step-by-step explanation:


 n - 2 = 10n + 4/2

 n - 10n = 4/2 + 2

 -9n = 4/2 + 4/2 ( taking LCM of 4/2 and 2)

 -9n = 8/2

 -9n = 4

    n = 4 / -9

   

   therefore n = -4 /9 ( since the minus sign doesn't make a difference whether placed at numerator or denominator) .

The sum of a 3 digit number and a 1 digit number is 217. The product of the numbers is 642. If one number is between 200 and 225
algol [13]
Let, the numbers be "x" and "y". Consider "x" as the triple digit number.
Now, according to the question,
x + y = 217..........................equation (1)

x * y = 642............................equation (2)

Now,
Taking equation (2),
x * y = 642
y = 642 / x..................................equation (3)

Now, Taking equation (1),
x+y=217

Substituting the value of y from equation (3), we get,

x+ \frac{642}{x} =217

\frac{x *x+642}{x} =217

x^{2} +642 =217*x

x^{2} +642 =217x

x^{2} +642-217x =0

x^{2} -217x+642 =0

x^{2} -3x-214x+642 =0

x(x-3)-214(x-3)=0

(x-3)(x-214)=0

Using zero product property,
EITHER,
           x - 3 = 0
                x = 3
OR,
          x - 214 = 0
                  x  = 214
Since, "x" is the triple digit number, x = 214.
Now,
Taking equation (2),
x * y = 642
Substituting the value of "x" in the equation, we get,
(214) * y = 642
y = 642 / 214
y = 3

So, the numbers are 214 and 3.
