<h3>What is unit conversion?</h3>

Unit conversion is a multi-step process that involves multiplying or dividing by a numerical factor and, more specifically, a conversion factor.

  • The process may also necessitate selecting the appropriate amount of significant digits and rounding.
  • Different conversion units are employed to measure various parameters.
  1. Measuring Temperature
  2. Measuring Length
  3. Measuring Capacity
  4. Measuring Weight
  • Conversion of units is defined as the process of converting between different units & measurements of a given quantity using multiplication or division.
  • Conversion is the method of changing the amount of one form in terms of mathematics, such as inches to millimeters or liters to gallons.
  • Units are used in the measurement of length, weight, capacity, temperature, and speed.

Find the amount in a account where $200 is invested at 3.5% compounded quarterly for a period of 3 years.
AlexFokin [52]

The amount after 3 years would be $221.74

<u>Explanation:</u>

Given:

Principal, P = $200

Rate of interest, r = 3.5%

Time, t = 3 years

Amount, A = ?

We know:

A = P(1+\frac{r}{100})^t

Substituting the value we get:

A = 200(1+\frac{3.5}{100} )^3\\\\A = 200 X 1.108\\\\A = 221.74

Therefore, the amount after 3 years would be $221.74

Help ASAP 15 points
zhuklara [117]

Answer:

Step-by-step explanation:

a) Let's x the length of the side of the small square.

Thus,

x^{2}  + (\sqrt{40})^2 = (\sqrt{50})^2

x^{2}  + 40 = 50

x^{2}  = 50 - 40

x^{2}  = 10

x = \sqrt{10}

x=3.16

b) Now, the area of the small square is

A= x^{2}

A=(3.16)^2

A=9.99

6. List the factors, of 30.<br> 1,30,5,6<br> Is this number prime or composite?
Tems11 [23]

Answer:

The number 30 is composite

Step-by-step explanation:

It is a composite because multiple numbers can go into 30 like 6 and 5 or 3 and 10. A prime number is like 3 because only 3 and 1 can go into it. 2 and 5 and 7 is also a prime number.

The sum of two numbers is 47 and the difference is 25 . what are the numbers?
taurus [48]
The numbers are:  36 and 11 .
______________________________________________
Explanation:
______________________________________________
Let us represent the TWO (2) numbers with the variables;
         "x" and "y" .
__________________________________________
     x + y = 47 .

     y − x = 25.
__________________________________________
Since:  " y − x = 25 " ;

Solve for "y" in terms of "x" ;

  y − x = 25  ;

Add "x" to each side of the equation:
_____________________________________________
   y − x + x  = 25 + x  ;

to get:

   y = 25 + x .

Now, since:

  x + y = 47 ;

Plug in "(25 + x)" as a substitution for "y"; to solve for "x" :

x + (25 + x) = 47  ;

x + 25 + x + 47 ;

2x + 25 = 47 ;

Subtract "25" from each side of the equation:

2x + 25 − 25 = 47 − 25 ;

2x  = 22  ;

Divide EACH SIDE of the equation by "2" ;
 to isolate "x" on one side of the equation; and to solve for "x" ; 
 
2x / 2 = 22 / 2 ;

    x = 11 ;
______________________________________________
x + y = 47<span> ;

</span>Plug in "11" for "x" into the equation ; to solve for "y" ;

11 + y = 47 ;

Subtract "11" from EACH SIDE of the equation;
  to isolate "y" on one side of the equation; and to solve for "y" ;

 11 + y − 11 =  47 − 11  ;

            y = 36 .
___________________________________________
So:  x = 11 , y = 36 ;
___________________________________________
 Let us check our work:

y − x = 25 ;

36 − 11 =? 25 ?  Yes!

x + y = 47 ;

36 + 11 =? 47 ? Yes!
______________________________________________
The numbers are:  36 and 11 .
