Answer:
222cm
Step-by-step explanation:
8*7.5*2=120
3.4*7.5*4=102
222cm
It is 7
2*2x = 4x + 2 = 30
4x = 28
x = 7
Answer:
1 5/9 OR 14/9
Step-by-step explanation:
First we need to find out what the question is asking. How much sugar will she need if she wants to make 2 1/3 batches?
Next, we must see if we need to divide, subtract, multiply, or add. We need to divide.
2 1/3 divided by 1 1/2
Convert mixed numbers to improper fractions: 2 1/3=7/3 1 1/3=3/2
Apply the fraction rule a/b/c/d=a*d/b*c: 7*2/3*3
14/9 OR 1 5/9
Answer:
Michael is 21 years old while Jean is 7 years old.
Step-by-step explanation:
Given that Micheal is three times as old as Jean, but in seven years he will be twice old as she will be, to determine how old are they both at this time, the following calculation must be performed:
M = 3J
M + 7 = 2J + 7
7 = 1/3
7 x 3 = 21
21 + 7 = 28
7 + 7 = 14
21 / 7 = 3
28 / 14 = 2
Therefore, Michael is 21 years old while Jean is 7 years old.
Answer:
static
Step-by-step explanation:
Static methods or variables are called on the class name and not on the object (although some programming languages like C# allow static methods to be called on objects). In fact, you do not need to have created any object before you call a static method. It is quite possible to have all the methods in a class as static, in which case the class is effectively static. Such classes are usually utility classes. Most times, they are not instantiable.
Instance methods are called using the name of an object.
