An account earns simple interest. Find the annual interest rate.

Mathematics
1 answer:
strojnjashka [21]3 years ago
4 0

Answer:

4% = r

Step-by-step explanation:

I = PRT

where I is the interest, P is the principle  R is the rate, T is the time

30 = 250 *r* 3

30 = 750r

Divide each side by 750

30/750 = 750r/750

.04 = r

Changing to percent form

4% = r

You know that a number 8 less than 60 is the number 52. so, you could rewrite your answer from the previous part as, "what numbe
svetoff [14.1K]
I'm a little confused by your question. 

You said 60-8 = 52 which is true.

Then, you asked 4x = 52 in an integer form
                           x = 52/4
                           x = 13. (Is that what you're asking?)

I'm not sure if this helps, but please comment if you need any help! Hope this helps though! :D

The position of a passenger train that is traveling at an initial speed of 14 feet per second and continues to accelerate can be
salantis [7]

Solving the system of equations, it is found that a viable time that the trains are side by side is given by:

B. 15 sec

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the equations are:

y = 14t^2

y = 130t + 1200

They will be side by side when:

14t^2 = 130t + 1200

14t^2 - 130t - 1200 = 0

It's solution is a quadratic function with coefficients a = 14, b = -130, c = -1200, hence:

\Delta = (-130)^2 - 4(14)(-1200) = 84100

x_1 = \frac{130 + \sqrt{84100}}{28} = 15

x_2 = \frac{130 - \sqrt{84100}}{28} = -5.71

Time is a non-negative measure, hence option B is correct.
