Let the speed of the current be y and the speed of Micah's sailing speed be x. Then 4.48/(x + y) = 0.32
4.48/(x - y) = 0.56
0.32x + 0.32y = 4.48 . . . (1)
0.56x - 0.56y = 4.48 . . . (2)
(1) x 7 => 2.24x + 2.24y = 31.36 . . . (3)
(2) x 4 => 2.24x - 2.24y = 17.92 . . . (4)
(3) - (4) => 4.48y = 13.44
y = 3
From (1), 0.32x + 0.32(3) = 4.48
0.32x = 4.48 - 0.96 = 3.52
x = 3.52/0.32 = 11
Therefore, the speed of the current is 3 miles per hour. Answer is 3 miles per hour

Answer:</h2>
The solution of the inequality is:

<h2>
Step-by-step explanation:</h2>
We are given a inequality in terms of variable x as:

Now we are asked to find the solution of the inequality i.e. we are asked to find the possible values of x such that the inequality holds true.
We may simplify this inequality as follows:
On using the distributive property of multiplication in the left hand side of the inequality we have:

The solution is: 
Answer:
For a the answer is 1/20 or 5%. For b the answer is 6/20 or 30%.
Step-by-step explanation:
a) There are 20 spots the dart can land on. To land on one specific spot, it would be 1/20. 1 spot out of 20 spots.
b) There are 20 spots the dart can land on. To land on any of the 6 spots, it would be 6/20. 6 spots out of 20 spots.
Answer:
Step-by-step explanation:
Circle degrees total 360 .
360 - 126 -54-54 (other side of vertical angles) equals 126 degrees left for the other two remaining sections.
14x+4 +15x+6 =126
19x+10 = 126
29x = 116
x=4 . answer .
The simplified expression for combined amount saved by Donna and her husband is 106.30N+50
Step-by-step explanation:
Given,
Function for amount saved by Donna;
A = 50+30.65N
Where N is the number of weeks.
Function for amount saved by Donna's husband
B = 75.65N
Let ,
The combined total amount saved be T.
T = A+B

The simplified expression for combined amount saved by Donna and her husband is 106.30N+50
