Answer:

its 90,000

Step-by-step explanation:

just put the zeros together then multiply 3x3

Answer:

The missing value is 5.

Step-by-step explanation:

Since we already have x-value for the equation. What we need to do is to substitute the value of x in the equation.

Substitution

[tex]5x - 2y = 30[/tex]

Then we substitute x = 8 in the equation.

[tex]5(8) - 2y = 30 \\ 40 - 2y = 30 \\ 40 - 30 = 2y \\ 10 = 2y \\ \frac{10}{2} = y \\ 5 = y[/tex]

Answer Check

It is better to check the answer before jumping to the conclusion. We can check if the answer is right by substituting both terms in the equation. If the equation is true then the answer is correct. If the equation is false then one of the term is incorrect.

[tex]5x - 2y = 30[/tex]

Substitute x = 8 and y = 5 in the equation.

[tex]5(8) - 2(5) = 30 \\ 40 - 10 = 30 \\ 30 = 30[/tex]

The equation is true for (8,5)

Therefore, the missing value is 5.

19/15

Step-by-step explanation:

We need to find the difference, so subtraction. But first we should make them improper fractions:

(18/5)-(7/3)

Lets make the common denominator 15:

Answer: 2662.25 (now u just need to round it to the whole)

Step-by-step explanation: Ok we know that it can last 5750 years, and we know 53.7 percent of those years is gone, meaning it only got 46.3 percent of it years left. until it gone. So 46.3 percent of 5750 is 2662.25. Now go round it if u need to.

The ratio of the change in the y and x values, in the table gives the slope

graph of the linear function.

Correct response:

From the given table, we have;

The first difference of the y-values = 2 - 8 = -6 = Constant

The rate of change of the x-values = 1 = Constant

Therefore;

The function is a linear function;

The slope, m, is given by the formula;

[tex]Slope, \ m = \mathbf{ \dfrac{y_2 - y_1}{x_2 - x_1}}[/tex]

Taking a pair of points as follows;

(0, -4) = (x₁, y₁)

(2, -16) = (x₂, y₂)

We have;

[tex]m = \dfrac{-16 - (-4)}{2 - 0} = \dfrac{-16 + 4}{2} = \dfrac{-12}{2} = \mathbf{ -6}[/tex]

Answer:

1 L = 1000 ml

Step-by-step explanation:

342L = 342 ml

645 ml = 645 ml

The given quantity 342 l 645 ml can be written as 342645 ml.

Given that, 342 l 645 ml.

Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.

We know that, 1 l = 1000 ml

Now, 342 l = 342000 ml

So, 342 l 645 ml = 342000+645 = 342645 ml

Therefore, the given quantity 342 l 645 ml can be written as 342645 ml.

Step-by-step explanation:

Answer:

Option B

Step-by-step explanation:

Let's take a vertex G of quadrilateral GHJK to understand the rule for the translation,

From the graph attached,

Coordinates of G → (-5, 5)

Coordinates of the image point G' after the translation → G'(-5, 5)

Let the point G is translated 'a' units to the right and 'b' units down,

Rule for this translation,

G(x, y) → G'(x + a, y - a)

By this rule,

G(-5, 5) → G'(-5 + a, 5 - a)

-5 + a = -5 ⇒ a = 0

5 - a = 5 ⇒ a = 0

Therefore, vector that defines the translation will be,

<0, 0>

Option B is the the correct option.

The vector that describes the translation of the image is: b. (0, 0).

Recall the rules of translation:

Thus, from the image given to us showing the image of GHJK, using one of the vertex J' (-3, 3) and the translation rule, [tex](x + a, y - b)[/tex], the vector describing the translation can be determined as follows:

The coordinates of vertex J = (-3, 3)

[tex]x = -3 \\\\ y = 3[/tex]

[tex]J(-3, 3) = (-3 + a, 3 - b)\\\\-3 = -3 + a\\\\-3 + 3 = a\\\\\mathbf{0 = a} \\\\\\3 = 3 + b\\\\3 - 3 = b\\\\\mathbf{0 = b} \\\\[/tex]

Therefore, the vector that describes the translation of the image is: b. (0, 0).

Step-by-step explanation:

Given

The attached graph

Required

Determine the linear equation

First, we need to calculate the slope

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

From the graph, the following relationships exist:

[tex](x_1,y_1) = (4,0)[/tex]

[tex](x_2,y_2) = (10,3)[/tex]

So, the expression for calculating slope becomes:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m = \frac{3-0}{10-4}[/tex]

[tex]m = \frac{3}{6}[/tex]

[tex]m = \frac{1}{2}[/tex]

Next, we calculate the equation using:

[tex]y - y_2 = m(x - x_2)[/tex]

This gives:

[tex]y - 3 = \frac{1}{2}(x - 10)[/tex]

Open bracket

[tex]y - 3 = \frac{1}{2}x - 5[/tex]

Make y the subject:

[tex]y = \frac{1}{2}x - 5+3[/tex]

[tex]y = \frac{1}{2}x - 2[/tex]
