Answer:
Both Lindsay and Sharon are wrong.
Step-by-step explanation:
When Lindsay was doing her problem, she put 100 on the bottom and 45 on the top, when it should have been the other way around.
Sharon would have been correct if she had used the right measuring unit. 2/5 of a milliliter should have been 2/5 of a liter.
Answer:
the factor of 25 is : 1, 5, 25
This the only option to find x since doing the other way like 3x + 2 = 3x + 2 gives it an infinite solution.
4x - 1 = 3x + 2
-3x -3x
1x - 1 = 2
+1 +1
1x = 3

1 1
x = 3
Check:
4(3) - 1 = 3(3) + 2
12 - 1 = 9 + 2
11 = 11
Answer:
180
Step-by-step explanation:
5(2)^2 (3)^3
5(4) (27)
4(27) = 108
5(108) = 540*
Answer:
The arc length of the semicircle is: 
, which is approximately 34.5575
Step-by-step explanation:
Recall that the length of a circumference of radius R is given by:
therefore, the arc length of a semicircle (half of the circle) would be given by half of the previous expression:
So, in our particular case of radius 11, the formula for the arc length of the semicircle becomes:
