The decimal 0.1 is a rational number because it can be expressed as the fraction 1/10, which is the correct answer to the student's question.

The student asked to choose a fraction that correctly completes the sentence: 0.1 is a rational number because it can be written as ___. The correct choice is 1/10. This is because the decimal 0.1 can be converted directly to the fraction 1/10 by placing the digit 1 in the numerator and 10 in the denominator, which signifies the decimal's place value. Rational numbers are those that can be expressed as a fraction where both the numerator and the denominator are integers, and the denominator is not zero.

Answer:

-9

Step-by-step explanation:

10-15 = -5 I-5I= 5

5*-2= -10

5+-10+-4 = -9

Considering that 30% of $7.50 is the same as 0.3/7.5, you would get $2.25 as the markup price. So by adding $7.50 with $2.25, Brittany would charge $9.75 per car magnet.

When we can write a number in fraction form then it is a rational number.

We converted the  decimal number into a fraction so it is rational

The answer is B. 57/90, rational.

To find the x-intercept of the equation y = -13x + 3, set y to zero and solve for x to get (3/13, 0). For the y-intercept, set x to zero and solve for y, resulting in (0, 3). These intercepts are then plotted and connected to graph the equation.

Determining X and Y Intercepts

To determine the x-intercept of the linear equation y = -13x + 3, we need to set y to zero and solve for x:

0 = -13x + 3

13x = 3

x = 3/13

So, the x-intercept is (3/13, 0).

To determine the y-intercept, we set x to zero and solve for y:

y = -13(0) + 3

y = 3

Thus, the y-intercept is (0, 3).

Plotting the Intercepts

On graph paper, mark the x-intercept at (3/13, 0) and the y-intercept at (0, 3). Then use a ruler to draw a straight line that passes through these points; this line represents the equation y = -13x + 3.

The slope is the rate of change along a line. However, in this scenario, the slope is not required to plot the line since we already have the intercepts. Nonetheless, for your reference, the slope (m) in the equation y = mx + b corresponds to -13, indicating a decline of 13 units in the y-direction for each single unit increase in the x-direction.

The correct symbol to make the statement -|y|? |-y| true is '=', because the absolute value of 'y' and '-y' are always equal, regardless of whether 'y' is positive or negative.

The correct symbol to make the statement true is '='. This is because the absolute value of any number, positive or negative, is always positive, or zero in the case of zero itself. So no matter what value 'y' takes on, |-y| and |y| will always be equal.

For example, let's consider that y = -5. Then |-5| = 5 and |5| = 5. Here |-y| and |y| are equal.

If y = 5, then |-5| = 5 and |5| = 5. Here too, |-y| and |y| are equal. Therefore, no matter if 'y' is positive or negative, the absolute value of 'y' and '-y' are always equal.

Answer:

The smallest possible page number that would have been assigned is 12.

Step-by-step explanation:

Number of pages assigned for homework = x

The 'x' is the number which divisible by both 2 and 12.

2 = 1 × 2 (prime number)

12 =  1 × 2 × 2 × 3 (Composite number)

The smallest possible page number that could have been assigned will be equal to lowest common multiple of 1, 1, 2, 2 and 3.

Answer:

110 people need to attend the dance in order to cover the cost.

Step-by-step explanation:

Bentley Manufacturing Company wants to rent a private club for its annual dance.

The total cost will be $1,045.

The committee charges $9.50 per person.

So, let the total number of persons attending be = x

So, this situation can be represented as:

[tex]9.50x=1045[/tex]

This gives x = 110

So, 110 people need to attend the dance in order to cover the cost.

Step 1: Add 3 to both sides.

2x-3+3=7+3

2x=10

Step 2: Divide both sides by 2.

2x/2=10/2

Step-by-step explanation:

The formule is about area of a circle.

[tex]\pi x^{2} = a[/tex]

We need to solve the equation for x. Where x is the radius of the circle.

In order to solve it for x, we need isolate it for x on left side.

So, first we need to get rid pi from left side.

On dividing both sides by pi, we get

[tex]\frac{\pi x^2}\pi}=\frac{a}{\pi}[/tex]

[tex]x^2=\frac{a}{\pi}[/tex]

Taking square root on both sides, we get

[tex]\sqrt{x^2}=\sqrt{\frac{a}{\pi}}[/tex]

30×·15=4.50

then subtract 30 by 4.50 to get 25.50

.0825×30=2.475

now add 2.475+25.50+30= 57.975 round to 57.98

The final answer is 36.975. The expression simplifies to 36.975 when all calculations are completed.

1. 30 + (.0825 x 30):

To calculate this part, we first multiply 0.0825 (which is 8.25% written as a decimal) by 30. This gives us:

0.0825 x 30 = 2.475

Next, we add 30 to the result:

30 + 2.475 = 32.475

2. (15% x 30):

To calculate this part, we first convert 15% to a decimal by dividing it by 100:

15% = 15/100 = 0.15

Next, we multiply 0.15 by 30:

0.15 x 30 = 4.5

Now that we have the results from both parts, we add them together:

30 + (.0825 x 30) + (15% x 30) = 30 + 2.475 + 4.5 = 36.975

Arithmetic average = Sum of all the numbers /Total numbers

SO arithmetic average= {(-2)+(-5)+(-2)+(5)+(x)+(-3)+(10)+(3)+(8)+(-10)} / 10

                                      ={4x} /10

                                      =0.4 x

As Given Arithmetic average= 8

so   0.4x =8

270 degree counter clockwise is the same as 90 degrees clockwise.

If you imagine the (x,y) axes rotating 90 clockwise, you will see that what x becomes y, and what was y becomes negative x (after the rotation).

So x-->y, and y-->-x

So the answer (c) is the correct one.

Answer:

option C

Step-by-step explanation:

the correct answer is option C

when a point (x, y )  means point lies in the first quadrant is rotated counter-clockwise to 270° means now the point will be in the fourth quadrant.

hence, in algebraic notation we interchange x by negative x

and y remains the same and their value interchanges so,

the best-suited answer will be (x, y) → (y, -x)

hence, the answer will be option C

Answer:

Initial population is 3450 in the year 2000 and it decreases 80 every year.

Step-by-step explanation:

We are given with y=-80x+3450 where y is city's population and x is the number of years after 2000.

That is x=0 means the year 2000.

Hence y-intercept will represent the initial population which is nothing but 3450.

Since our equation slope =-80 which is negative means y is decreasing as x increases.

For x raises by 1, y decreases by 80.

That means population decreases by 80 for every year.

Answer:

The y-intercept indicates the population in the year 2000, so 3,450 people lived in the city in 2000. The negative slope indicates that the city is losing population. It loses 80 people each year.

Jim completed half the floor in 12 hours so it's [tex]12\times rate[/tex]= 12x 

Pete completed the other half of the floor in 10 hours so its [tex]10\times rate[/tex]=10y

As floor area is equal so,

[tex]12x=10y[/tex] .............(1)

Now, given is that Pete can lay 25 more tiles per hour than Jim, this gives=

[tex]y=x+25[/tex] ...... (2)
