PtichkaEL [24]
For the answer to the question above asking what was the amount of the withdraw if <span>Doris put $4000 in a 2-year cd paying 6% interest, compounding monthly. after 2 years, she withdrew all her money?</span>

First year Interest: I(1) = 4000[(1.005)^12 - 1] = 246.71 = penalty for early withdrawal 
Value after two years: P(2) = 4000(1.005)^24 = 4508.64 

Value after 2 years with penalty: V = 4000(1.005^24 - 1.005^12 + 1) = $4261.93

Instance variables are often called ____ to help distinguish them from other variables you might use. (3 pts.)
zzz [600]

Instance variables are often called "fields" to help distinguish them from other variables you might use.

<h3>What are Instance variables?</h3>

Instance variables are defined within a class but outside of any method, constructor, or block.

Some key points related to Instance variables are-

  • When heap space is allocated to an object, a slot is created for every instance variable value.
  • Whenever an object is created with keyword 'new,' instance variables are created, and they are destroyed whenever the object is destroyed.
  • Instance variables store values that need to be referenced by multiple methods, constructors, or blocks, as well as vital components of an entity's state which must be available throughout the class.
  • Before or after use, instance variables could be declared just at class level.
  • Variables, for example, can be given access modifiers.
  • Only those methods, constructors, and blocks in the class have access to the instance variables.

the ratio of number of girls and boys in a class is 4:3 if there are 20 girls find the number of boys. plz do it in process​
Ilya [14]

Answer:

15 boys

Step-by-step explanation:

Whatever number one side of the ratio is multiplied by, the other side has to be multiplied by that same number. So, we have to find the number that 4 is multiplied by to get 20. We can represent this as an equation, where the unknown number is x:

4x = 20

Divide both sides of the equation by 4 to find the value of x:

x = 5

4 was multiplied by 5 to get 20.

To find the number of boys, multiply 3 by 5:

3 * 5 = 15

If there are 20 girls, there will be 15 boys.
