Answer: </h3><h3>Fred has <u>20 students</u> and Lee has <u>22 students</u></h3>
=============================================================
Work Shown:
L = number of students in Lee's class
F = number of students in Fred's class
Lee has 1.1 times as many students compared to Fred
This means we have this equation
L = 1.1F
Whatever the value of F is, we multiply that by 1.1 to get the value of L
The two amounts L and F add to 42 total students
L+F = 42
1.1F + F = 42 .... replace L with 1.1F
2.1F = 42
F = 42/(2.1)
F = 20 .... Fred has 20 students
L = 1.1*F
L = 1.1*20
L = 22 .... Lee has 22 students
------------
Check:
L+F = 22+20 = 42
this confirms the answer
Answer:
6
Step-by-step explanation:
Maybe you want a suitable common denominator for 2/3 and 1/6. If so, you can observe that 3 is a factor of 6, so 6 is a suitable common denominator.
2/3 = (2/3)·(2/2) = (2·2)/(3·2) = 4/6
The equivalents, 4/6 and 1/6, share a common denominator of 6.
With a 20 ft leash, the dog can move in the circle. Now, knowing that he can move around in a circle, we just need to use the circle formula. A = 3.14(r) squared.
Since you use 3.14 for pi; A = 3.14(20) squared --> A = 1256
Answer = 1256
