Answer:
162.4
Step-by-step explanation:
A= 8 * side length * apothem/2
A = 8* 5.8 * 3.5
A = 162.4
You plug in number for number getting 194.8 which is equal to 2931
In order to use the simple interest formula, we first define the variables. The interest would be equal to Samuel's desired amount $ 2,488 minus the principal amount of $ 1,800 which is then equal to $ 688. The rate must be in decimal form which is equal to 0.12 while t is expressed in years. Substituting the values, t is equal to 3. Thus, it will take 36 <span>months for Samuel's account balance to reach $2,448. </span>
So the easiest way to solve this is to use the straight line provided .
180=90+61+x
180=151+x
29=x
