como escribir 0.4 en fraccion?

Answer:

The set of natural numbers does not have the inverse property under the operation of addition, because while −x would normally be the inverse for x under addition, there are no negative numbers in the set of natural numbers. The inverse must be in the set in order for the inverse property to hold!

Answer:

A.) 49.3

Step-by-step explanation:

To find the mean of a given set of data points, you need to add up all of the numbers given in the data set. So let's add these altogether:

43 + 55 + 51 + 62 + 64 + 38 + 35 + 45 + 51 = 444.

With that said, now we have to divide the number of how many numbers given into our so-far-answer of 444. There are 9 numbers in this data set, so we need to divide 9 into 444.

444 ÷ 9 = 49.33333...

The question asks us to round to the nearest tenth, which would be the first 3 in this situation. Normally, we would need a longer process for rounding, but since these are all 3's, we can do this faster. We can get rid of the other 3's and be left with the first letter of A.)'s answer.

I hope that this helps.

Answer:

792 m

Step-by-step explanation:

perimeter of a rectangle = 2l + 2b

⇒ perimeter of ground = (2 x 42) + (2 x 24) = 132 m

Perimeter = 1 round

⇒ 6 rounds = 6 x 132 = 792 m

Answer:

792 m

Step-by-step explanation:

First, calculate the perimeter.

= 2(42 + 24)

= 2(66)

= 132 m

Distance covered

= 132 x 6

= 792 m

Answer: 6 m

Step-by-step explanation:

The area of a rectangle is the length times the width.

We can set up an equation.

108 m^2 = 18 m * width

Width = 6 m

Choice A

Step-by-step explanation:

You would want to subtract the total amount you start with by the amount you need

Answer:

Total surface area of rectangular prism is 554 cm^2

Step-by-step explanation:

Surface area of rectangular prism

Length = 16 cm

width = 8 cm

height = 6 cm

Surface area of rectangular prism = 2 [ length x width +width x height +heightxlength]

= 2[ 16x8+8x6+6x16]

= 2[ 128+48+96]

= 2[ 272]

=554 cm^2

Answer:

Probability: [tex]\frac{1}{24310}[/tex]

Step-by-step explanation:

There are two methods:

1. Fraction method (Longer expression)

2. Combination method (Shorter expression)

Fraction method:

We want the numerator to be the number of students remaining and the denominator to be the total number of individuals (students + faculty) remaining after each selection.

[tex]\frac{8}{17}*\frac{7}{16} *\frac{6}{15} *\frac{5}{14} *\frac{4}{13} *\frac{3}{12} *\frac{2}{11} *\frac{1}{10} = \frac{1}{24310}[/tex]

Multiplying the fractions mean they are in the same combination during one single selection process.

Combination method:

Most calculators should have a permutation and combination function. We will use combination as there is no specific order in selecting students.

[tex]\frac{8C8*9C0}{17C8} = \frac{1}{24310}[/tex]

Pretend the C means "Choose", We want to choose all 8 students and 0 faculty, therefore "8 choose 8" for students and "9 choose 0" for faculty. Lastly divided by "17 (total individuals) choose 8 (students only)" to make it into a probability, similar to the fraction method but way shorter.

Answer:

Answer: ??????

explain better than i can answer

Step-by-step explanation:

Answer:

Step-by-step explanation:

According to the diagram shown under the blue print , is says that 4 centimeters here equal 0.5 feet.

That means, that 8cm = 1 ft

So, what's the value of the remaining 2cm?

If we see, that 4=0.5

Then we can also see, that 4/2=2

And

2=0.25

so, basically, 2cm, equals 0.25 feet.

So, if we add up all (for 8cm and 2cm), then we get 1.25 feet.

Thanks!

Answer:

(5, -1)

Step-by-step explanation:

Equation 1:   3x + y = 14

Equation 2:   2x - 2y = 12

Rewrite equation 1 to make y the subject:

⇒ y = 14 - 3x

Substitute this into equation 2 and solve for x:

⇒ 2x - 2(14 - 3x) = 12

⇒ 2x - 28 + 6x = 12

⇒ 8x - 28 = 12

⇒ 8x = 40

⇒ x = 5

Substitute found value for x into either equation and solve for y:

using equation 1:

⇒ 3(5) + y = 14

⇒ 15 + y = 14

⇒ y = -1

Therefore, the solution to the system is (5, -1)
