What is 0.4 as a simplified fraction

Mathematics
1 answer:
mestny [16]4 years ago
5 0

Answer: 2/5

Step-by-step explanation: Using the place value chart, we can see that the decimal 0.4 is four tenths, so we can write 0.4 as the fraction 4/10.

Notice however that 4/10 is not in lowest terms so we need to divide the numerator and the denominator by the greatest common factor of 4 and 10 which is 2.

So if we divide the numerator and the denominator by 2, we get the equivalent fraction 2/5.

Therefore, 0.4 can be written as the fraction 2/5 which is in lowest terms.

Mckenzie and Cara both tried to find the missing side of the right triangle.
LekaFEV [45]

Answer: Mckenzie is correct

<em>I had to reformat this section with the way it was typed, please let me know if I did anything wrong.</em>

<u>Mckenzie's Work</u>

a² + b² = c²

25 + 169 = c²

194 = c²

Square root 194 equals square root c squared.

c ≈ 13.93

<u>Cara's Work</u>

a² + b² = c²

25 + b² = 169

b² = 144

Square root b squared equals square root 144.

b ≈ 12

[] Right away we can tell that <u>Cara is not correct.</u>

-> Cara solves for b. We already have a b value, we need to solve for "c" in the equation.

[] Now let's look at Mckenzie.

-> Mckenzie does solve for the right variable, so let's see if she did it correctly.

-> First, she sets is up using a² + b² = c² since this is a right triangle. Next, she squares 5 to 25 and 13 to 169. Both correct.

-> Now they are added together. 25 + 169 do equal 194 so this looks correct.

-> Last, we square both sides. \sqrt{194} ≈ 13.928388 which rounds to 13.93, so it looks like <u>Mckenzie is correct</u>.

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Sydney wrote the equation y+1=12(x−3). y + 1 = 1 2 ( x − 3 ) . Explain her error and then write the correct equation in point-sl
yanalaym [24]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

Given equation:

\to y + 1 = 12 ( x - 3 )

Using formula:

\to \bold{y = mx +c}

Solving the given equation:

\to y + 1 = 12 ( x - 3 )\\\\\to y+1 =12x-36\\\\\to y=12x-36-1\\\\\to y= 12x-37\\\\

compare the value form the given formula:

\to m= 12

Correct equation \to  y= 12x-37

solpe \to m= 12
