If 30 cents out of every 1 dollar go to taxes, the remaining 70 cents is the net income. Therefore, the ratio of taxes to net income is 3:7.

The question asks for the ratio of taxes to net income if 30 cents out of every 1 dollar go to taxes. This question is asking for a mathematical comparison between the amount of money that goes to taxes and the remaining amount of money, which is the net income.

If 30 cents go to taxes out of 1 dollar, that means 70 cents (or $0.70) is the net income because 1 dollar minus 30 cents equals 70 cents. To arrive at the ratio, we compare the amount that goes into taxes to the net income. This would be 0.30 (taxes) to 0.70 (net income).

When we express this as a ratio in simplest form, we do not usually use decimals. Instead, we can convert the decimal into a whole number. Think of the 0.30 and the 0.70 as 30 and 70. The greatest common divisor of 30 and 70 is 10. If we divide both numbers by 10, we get 3 and 7. So, the ratio of taxes to net income is 3:7. Thus, the correct option is C. 3 : 7.

Answer:

it's c

Step-by-step explanation:

because for .087  you move the decimal 3 times

                  so the decimal is going to end up 08.7

                                                                                here

We can write 0.87 as 87 / 100.

Option D is the correct answer

Given,

0.087

We have to see the other form it can be written.

The numbers which have a decimal point.

Example: 23.4

It can be written in fractions aswell.

23.4 = 234/10

We have,

0.87

Since there are two numbers after the decimal point we can write it as:

= 0.87
= 087 / 100

= 87 / 100

Thus we can write 0.87 as 87 / 100.

Option D is the correct answer.

Final answer:

Catrina used 25 tiles to create a square, which means she made 5 rows with 5 tiles in each row, as the square root of 25 is 5.

Explanation:

Catrina used 25 square green tiles to form a square in the middle of her floor.

To find out how many rows she made and how many tiles she put in each row, we need to think about the properties of a square.

A square has equal sides, so the number of tiles in each row must be the same as the number of rows. Since the total number of tiles is a perfect square (25), we find the square root of 25 to determine the size of each side of the square.

The square root of 25 is 5, so Catrina created 5 rows with 5 tiles in each row. This forms a perfectly square area on her floor with green tiles.

Answer: The graph is represented by the inequality y>3x+2

Step-by-step explanation:

Linear inequality is like linear equation just we have inequality signs (<,>,≤,≥) instead of equal sign(=).

In the given question we have the linear inequality represented by graph

We can see the line in the graph passing through the point (-3,-7)

Let's check which option satisfy the point

1) y<3x+2 for this the line should be y=3x+2

⇒ -7=3(-3)+2

⇒-7= -9+2⇒-7=-7,which is true.

2) y>3x+2 which similar as first.

3) y<x+2 for this the line should be y=x+2

⇒ -7= -3+2

⇒-7=-1 which is not true.

4) y > x + 2 is similar to third.

Option 3) and 4) cannot be the required linear inequality.

Now from 1) and 2) , 2) should be the required linear inequality as the graph is shaded above the line and that must be for y (>) greater than inequality. [ for y (<) less than inequality the graph must be shaded below the line]

Therefore, 2)  y > 3x + 2 is the required linear inequality which is represented by the graph.

The linear equality represented by the graph is [tex]\boxed{{\mathbf{y>3x+2}}}[/tex] and it matches with [tex]\boxed{{\mathbf{OPTION B}}}[/tex] .

Further explanation:

It is given that a line passes through points [tex]\left({0,2}\right)[/tex] and [tex]\left({-3,-7}\right)[/tex]  as shown below in Figure 1.

The slope of a line passes through points [tex]\left({{x_1},{y_1}}\right)[/tex] and [tex]\left( {{x_2},{y_2}}\right)[/tex]is calculated as follows:

[tex]m=\frac{{{y_2}-{y_1}}}{{{x_2}-{x_1}}}[/tex]                    ........(1)

Here, the slope of a line is denoted as [tex]m[/tex] and points are [tex]\left({{x_1},{y_1}}\right)[/tex] and [tex]\left({{x_2},{y_2}}\right)[/tex].

Substitute [tex]0[/tex]  for [tex]{x_1}[/tex] , [tex]2[/tex]  for [tex]{y_1}[/tex] , [tex]-3[/tex]  for [tex]{x_2}[/tex]  and [tex]-7[/tex]  for [tex]{y_2}[/tex]  in equation (1) to obtain the slope of a line that passes through points [tex]\left({0,2}\right)[/tex] and [tex]\left({-3,-7}\right)[/tex] .

[tex]\begin{aligned}m&=\frac{{-7-2}}{{-3-0}}\\&=\frac{{-9}}{{-3}}\\&=3\\\end{aligned}[/tex]

Therefore, the slope is [tex]3[/tex] .

The point-slope form of the equation of a line with slope [tex]m[/tex]  passes through point [tex]\left({{x_1},{y_1}}\right)[/tex] is represented as follows:

[tex]y-{y_1}=m\left({x-{x_1}}\right)[/tex]                                 .......(2)

Substitute [tex]0[/tex]  for [tex]{x_1}[/tex] ,  [tex]2[/tex] for [tex]{y_1}[/tex]  and [tex]3[/tex]  for [tex]m[/tex]  in equation (2) to obtain the equation of line.

[tex]\begin{aligned}y-2&=3\left({x-0}\right)\\y-2&=3x\\y&=3x+2\\\end{aligned}[/tex]

Therefore, the value of [tex]y[/tex]  is [tex]3x+2[/tex] .

Since the shaded part in Figure 1 is above the equation of line [tex]y=3x+2[/tex], therefore, greater than sign is used instead of is equal to.

Thus, the linear inequality is [tex]y>3x+2[/tex]  as shown below in Figure 2.

Now, the four options are given below.

[tex]\begin{aligned}{\text{OPTION A}}\to &y<3x+2\hfill\\{\text{OPTION B}}\to &y>3x+2\hfill\\{\text{OPTION C}}\to &y<x+2\hfill\\{\text{OPTION D}}\to &y>x+2\hfill\\\end{aligned}[/tex]

Since OPTION B matches the obtained equation that is [tex]y>3x+2[/tex] .

Thus, the linear equality represented by the graph is [tex]\boxed{{\mathbf{y>3x+2}}}[/tex]  and it matches with [tex]\boxed{{\mathbf{OPTION B}}}[/tex].

Final answer:

Ana's conjecture that Raul lost 2/5 of his teeth is correct, as it simplifies from Raul's stated 4/10 after losing 8 out of the total 20 baby teeth.

Explanation:

Raul has said he lost 4/10 of his baby teeth, while Ana said Raul lost 2/5 of his teeth. To figure out which conjecture is true, we must consider Raul's claim first. Since a human usually has 20 baby teeth and Raul has lost 8 of those, we calculate the fraction of teeth he has lost by dividing the number of lost teeth by the total number of baby teeth: 8 ÷ 20 = 2/5. This simplifies to the fraction 2/5, which means Ana's conjecture is indeed the correct one. Both fractions actually represent the same value, because when you simplify 4/10 by dividing the numerator and the denominator by 2, you get 2/5.

The number that corresponds to the prime factorization '2 to the 3rd power times 3 times 5 to the 2nd power' is 600. Calculate this by resolving each component then multiply the results.

The question revolves around finding the result of a number given its prime factorization, specifically when the prime factorization is '2 to the 3rd power times 3 times 5 to the 2nd power'. Let's start by resolving each of those components:

So, with these resolved components, we only have to multiply the results, which is 8 (from 2 cubed) times 3 times 25 (from 5 squared).

This would give us the answer: 8 * 3 * 25 = 600.

Therefore, the number that corresponds to the prime factorization '2 to the 3rd power times 3 times 5 to the 2nd power' is 600.

What is a Parabola?

A Parabola, open curve, a conic section produced by the intersection of a right circular cone and a plane parallel to an element of the cone. A parabola is a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line

The equation of the parabola is given by

( x - h )² = 4p ( y - k )

where ( h , k ) is the vertex and ( h , k + p ) is the focus

y is the directrix and y = k – p

The equation of the parabola is also given by the equation

y = ax² + bx + c

where a , b , and c are the three coefficients and the parabola is uniquely identified

Given data ,

Let the equation be represented as A

Now , the parabola is

f ( x ) = | x − 4 | + 3   be equation (1)

Now ,

The vertex of f ( x ) = | x | is located at the origin, (0,0)

So , in the form f ( x ) = a | x - h | + k, the h-value translates the graph left/right and the k-value translates the graph up/down

And ,

In the function, f(x) = | x - 4 ) | + 3 , the h-value is 4, and the k-value is 3

So , the vertex of the function moves from the origin, (0,0) and translates 4 units right and 3 units up.

Therefore , the vertex is located at P ( 4,3 )

Hence , the vertex of equation is at P ( 4 , 3 )

The solutions to the quadratic equation (x - 4)² = 36 are

x = 10 and x = -2.

We have,

To solve the quadratic equation (x - 4)² = 36, we can start by taking the square root of both sides of the equation.

However, we need to consider both the positive and negative square roots because squaring a number eliminates the sign.

Taking the square root of both sides, we have:

√[(x - 4)²] = √36

Simplifying further:

|x - 4| = 6

Now, we can set up two separate equations to consider both the positive and negative square roots:

x - 4 = 6 or x - 4 = -6

Solving the first equation:

x - 4 = 6

Adding 4 to both sides:

x = 10

Solving the second equation:

x - 4 = -6

Adding 4 to both sides:

x = -2

Therefore,

The solutions to the quadratic equation (x - 4)² = 36 are

x = 10 and x = -2.
