Answer: 5/66 (I'm so sorry if this is wrong)

Step-by-step explanation: First you divide 10 and 3 3/4. 10 ÷ 3 3/4 = 0.0757575757575.

To turn that back into to a fraction, let X equal the decimal number

Equation 1:

X = 0.0757575757575 (1)

With 12 digits in the repeating decimal group,

create a second equation by multiplying

both sides by 1012 = 1000000000000

Equation 2:

1000000000000X = 75757575757.5757575757575 (2)

Subtract equation (1) from equation (2)

1000000000000X = 75757575757.5757575757575...

X = 0.0757575757575...

999999999999X = 75757575757.5

We get

999999999999X = 75757575757.5

Solve for X

X = 75757575757.5/999999999999

Multiply to eliminate 1 decimal places.

Here you multiply top and bottom by 1 10's

= 101 = 10

75757575757.5/999999999999 × 10/10 = 757575757575/9999999999990

Find the Greatest Common Factor (GCF) of 757575757575 and 9999999999990, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 151515151515,

757575757575/9999999999990 ÷ 151515151515/151515151515 = 5/66

Therefore

X = 5/66

In conclusion,

0.0757575757575 = 5/66

PLEASE HELP!!!! A boat can travel at an average speed of 10 miles per hour in still water. Traveling with the current, it can tr

Soloha48 [4]

Answer:

2 mph

Step-by-step explanation:

Let the speed of current be x

Speed of the boat in same direction as current is

10 + x

Speed against the current is

10 - x

Based on the given we get the equation for time

6/(10 + x) = 4/(10 - x)

Solving for x

6(10 - x) = 4(10 + x)
60 - 6x = 40 + 4x
6x + 4x = 60 - 40
10x = 20
x = 2

The answer is 2 mph

If B is the midpoint of AC and the length of AC is 23.8 what is the legength of AB

swat32

Hey there,

So explain and to illustrate (how $B$ is the midpoint of $AC$ and the length of $AC$ is 23.8 what is the length of $AB$

 A-----------------B----------------C

So, $\boxed{AC}$ in the problem here is to be considered the (Whole area of this line). $AC$ is the whole thing.

So, what we do in this problem, we do . . .

23.8 ÷ 2 because we need to find what is $AB$ , so we will find the one half of it, which in this illustration is to be considered $AB$

23.8 ÷ 2 = $\boxed{11.9}$

$\boxed{AB=11.9}$

Hope this helps.
