find the simple interest earned when the principal is $500 at a rate of 10% held in the bank for 8 months
olga nikolaevna [1]

The Simple interest will be "$400".

Given values are:

  • Principle, P = $500
  • Interest rate, R = 10%
  • Time, T = 8 months

As we know,

→ Simple \ interest (SI) = \frac{P\times R\times T}{100}

By substituting the values, we get

→                                  =\frac{500\times 10\times 8}{100}

→                                  =5\times 10\times 8

→                                  = 400 ($)

Thus the above response is correct.

Please help. Thank you :)

Okay, first let's look at what they give us!


The measure of angle 2 is 3x + 1


Measure of angle 3 is 2x + 4


And they give us that one angle is right which means it is 90°


Now if we use what we know of triangles, we know that all the angles in a triangle add up to equal 180 which means if we add angle 2, angle 3, and the right angle together we should get 180. Let's write an equation for it:


3x + 1 + 2x + 4 + 90 = 180


First we will add together liked terms!


3x + 2x = 5x


1 + 4 + 90 = 95


This gets us:


5x + 95 = 180


Second, let's get rid of that 95 by subtracting it from both sides, after doing this it should leave us with:


5x = 85


Third we need to get the x by itself and we can do it by dividing both sides by 5 to get:


x = 17


Now the question asks to find the measure of angle 2, given that angle 2 is 3x + 1 all there is left to do is to plug in 17 for x!

3(17) + 1


51 + 2 to get us 52!
