Answer:

3^-1, square root of 9, -0.25, and 0.6

Step-by-step explanation:

Rational numbers are numbers that you can turn into fractions.

3^-1 = 0.3333333333... which is also known as 1/3

square root of 9 = 3, which can be written as 3/1

-0.25 can be written as -1/4

0.66666666... = 2/3

The numbers 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.

A number system is defined as a system of writing to express numbers.

The rational numbers are those that can be expressed as a ratio of two integers.

3⁻¹ = 1/3, which is a rational number.

sqrt(12) = sqrt(4 x 3) = 2sqrt(3), which is irrational.

sqrt(9) = 3, which is a rational number.

-0.25 = -1/4, which is a rational number.

pi is irrational.

0.6 = 3/5, which is a rational number.

Hence, 3⁻¹ , sqrt(9), -0.25 and 0.6 are the rational numbers.

Answer:

8.82 feet

Step-by-step explanation:

Explanation:

Let's set up the ratio. We know that the actual length of the ship was 882 feet and we want to know how long the model will be. We also have a ratio of 1 model length to every 100 actual length. So we can write this as:

Model length

Ship length

=

1 Model length

100 actual length

And we can drop in some numbers (I'll also put in the variable

x

to represent the length of the ship model):

x

882

=

Let's cross multiply to solve for x:

Answer:

the aswer is 32

Step-by-step explanation:

The vertex of the parabola described by the equation 3y=2x^2-16x+18 is (m,n). the sum of m + n is 178/27.

To find the vertex of the parabola described by the equation 3y = 2x^2 - 16x + 18, we first need to put the equation in the standard form of a parabola, which is y = a(x - h)^2 + k, where (h, k) represents the vertex.

Let's begin by dividing the entire equation by 3 to simplify it:

y = (2/3)x^2 - (16/3)x + 6

Now, we need to complete the square to rewrite the equation in the form y = a(x - h)^2 + k:

y = (2/3)(x^2 - (8/3)x) + 6

Next, we need to find the value that completes the square for the expression inside the parentheses. To do that, we take half of the coefficient of x and square it:

(8/3) / 2 = 4/3

(4/3)^2 = 16/9

Now, we add and subtract 16/9 inside the parentheses:

y = (2/3)(x^2 - (8/3)x + 16/9 - 16/9) + 6

Now, we group the first three terms and factor the perfect square trinomial:

y = (2/3)((x - 4/3)^2 - 16/9) + 6

Next, distribute the (2/3):

y = (2/3)(x - 4/3)^2 - (2/3)(16/9) + 6

Now, simplify:

y = (2/3)(x - 4/3)^2 - (32/27) + 6

Finally, bring everything together:

y = (2/3)(x - 4/3)^2 + (142/27)

Now we can see that the vertex of the parabola is at the point (h, k) = (4/3, 142/27).

To find m + n, we simply add the x-coordinate (h) and the y-coordinate (k):

m + n = 4/3 + 142/27

To add these fractions, we need to find a common denominator, which is 27. Convert 4/3 to have a denominator of 27:

4/3 = (4/3) * (9/9) = 36/27

Now we can add the fractions:

m + n = 36/27 + 142/27

m + n = (36 + 142)/27

m + n = 178/27
