Answer:
the area of the circle is 4π
Step-by-step explanation:
The computation of the area of the circle is shown below:
As we know that
The area of the circle = πr^2
where
diameter = 4
So radius = diameter ÷ 2
= 4 ÷ 2
= 2
Now the area of the circle is
= π × 2^2
= 4π
hence, the area of the circle is 4π
So first, find out the total amount of money you make in 3 months.
If you make 1200 dollars a month, then in 3 months, you can make 3600 dollars. This is because 1 month salary + 1 month salary + 1 month salary = 3 month salary, and 1 month salary = 1200. So 1200 + 1200 + 1200 = 3600.
Since you're saving 2/5 of that, the simplest method to do this is to divide by 5, to find 1/5 of 3600, then multiply by 2 to find 2/5.
3600/5 = 720
720 * 2 = 1440
So you can save $1440 in three months.
Answer:
The system of equations are 
and 
Step-by-step explanation:
Given : There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than the yearbook club.
To find : Write a system of linear equations that represents the situation.
Solution :
Let x represent the number of students in the drama club
and y represent the number of students in the yearbook club.
There are a total of 64 students in a drama club and a yearbook club.
i.e. ....(1)
The drama club has 10 more students than the yearbook club.
i.e. ....(2)
Substitute the value of (2) in (1),
Substitute in (2),
Therefore, the system of equations are and
