To do this you can do (pay) x (hours) to work out how much Johnny makes for example:

8.25 x 29.5 = 243.375$ so the answer is 243.375$

Answer:

The correct answer is B) $243.397

Step-by-step explanation:

Your answer would be 1. Hope this helps :)

0.96 rounded to the nearest tenth is:

1

Because 6 is greater than 4. The number has to be greater than 4 for it to be rounded up, but if it's not, then the number only gets rid of the number behind the tenth.

Hope this helped! :D

Answer:

  a) 7

  b) 20

  c) 14

  d) 24

Step-by-step explanation:

The desired number is found by subtracting the given number from the square of the integer just higher than the root of the given number.

a) √42 ≈ 6.5, so the desired number is 7² -42 = 49 -42 = 7

__

b) √101 ≈ 10.05, so the desired number is 11² -101 = 121 -101 = 20

__

c) √470 ≈ 21.7, so the desired number is 22² -470 = 484 -470 = 14

__

d) √1000 ≈ 31.6, so the desired number is 32² -1000 = 1024 -1000 = 24

To simplify the expression √7{x 5} ×  √7{x 5}, you can multiply the radicands together and simplify the result.

To simplify the expression √7{x 5} ×  √7{x 5}

We can use the properties of radicals to simplify the expression. When multiplying radicals with the same index, we can simplify by multiplying the radicands together. In this case, the radicands are both x5, so the simplified form will be:

√7{x 5} ×  √7{x 5} = √7{x 5 × x 5} = √7{x10}

Therefore, the simplified form of the expression is √7{x10}.

Answer:

Tony pays $6.75 for his item, & Tanya pays $9 for her items

Step-by-step explanation:

Let Tanya's item be x, and Tony's be y. Set the system of equality:

3x = 4y

y = x - 2.25

Plug in x - 2.25 for y in the first equation

3x = 4(x - 2.25)

Distribute 4 to all terms within the parenthesis

3x = 4x - 9

Isolate the x. Subtract 4x from both sides

3x (-4x) = 4x (-4x) - 9

3x - 4x = -9

-x = -9

Isolate the x. Divide -1 from both sides

(-x)/-1 = (-9)/-1

x = 9

-------------------------------------------------------------------------------------------------------------------

Plug in 9 for x in the equation

y = x - 2.25

y = (9) - 2.25

y = 6.75

--------------------------------------------------------------------------------------------------------------------

Tony pays $6.75 for his item, & Tanya pays $9 for her items

~Rise Above the Ordinary

Answer: Yes it is possible. Angle DCF is also 50 degrees

=================================================

Check out the image attachment below. On that image, I've marked that angle EBA is congruent to angle BAC by the alternate interior angle theorem. Those angles are shown in red. Furthermore, angle BAC is congruent to DCF (corresponding angles) using a green marker. Finally, using the transitive theorem, you can connect the statements in a chain to say that angle EBA is congruent to angle DCF, which is why angle DCF is 50 degrees as well.

Answer:

The answer is [tex]6x^{3} +39x^{2}+54x[/tex]

Step-by-step explanation:

Volume of the rectangular prism = Length * Width * Height

Length (l) = [tex]x+2[/tex]

Width (w) = [tex]3x[/tex]

Height (h) = [tex]2x+9[/tex]

By substituting these values to the equation above,

Volume of the rectangular prism = [tex](x+2)*3x*(2x+9)[/tex]

                                                      =[tex](3x^{2} +6x)*(2x+9)[/tex]

                                                      =[tex]6x^{3} +27x^{2} +12x^{2} +54x[/tex]

                                                      =[tex]6x^{3} +39x^{2}+54x[/tex]

Therefore,

The answer is [tex]6x^{3} +39x^{2}+54x[/tex]

Answer:

Volume = [tex]6x^3+39x^2+54x[/tex]

Step-by-step explanation:

Prism is an object which has two  bases which are parallel to each other and other faces are parallelograms .

Rectangular prism is a three dimensional figure which has 6 faces which are all rectangles .

Let l be the length of rectangular prism , w be the width of prism and h be the height of prism .

Then volume of rectangular prism is equal to [tex]lwh[/tex] .

We will also use formula: [tex]a(b+c)=ab+ac[/tex]

Here,

[tex]l=x+2\\w=3x\\h=2x+9[/tex]

Therefore,

volume of rectangular prism is calculated as follows:

[tex]V=\left ( x+2 \right )\left ( 3x \right )\left ( 2x+9 \right )\\=\left ( 3x^2+6x \right )\left ( 2x+9 \right )\\=3x^2\left ( 2x+9 \right )+6x\left ( 2x+9 \right )\\=6x^3+27x^2+12x^2+54x\\=6x^3+39x^2+54x[/tex]

Reggie's score changed by 350 points.

Reggie lost 4 spaceships in level 3 of a video game, and he lost 50 points for each spaceship. So, the total points lost would be 4 multiplied by 50, which is 200 points. However, when Reggie completed level 3, he earned a bonus of 550 points. To find out how much his score changed, we need to consider both the points lost and the bonus earned.

Points lost: 4 spaceships x 50 points/spaceship = 200 points

Bonus earned: 550 points

Score change: Bonus earned - Points lost = 550 points - 200 points = 350 points

Therefore, Reggie's score changed by 350 points.

Answer:

3/6is not a integer.

Step-by-step explanation:

6/3 integer

6/2 integer

3/6 not a integer

Final answer:

The fraction 3/6 is not an integer because it equals 0.5, which is a fraction and not a whole number.

Explanation:

To determine which of these values is not an integer, we need to perform the division for each fraction:

Therefore, 3/6 is not an integer because when you divide 3 by 6, you get a fractional number rather than a whole number.

The mean number of people in each spinning class last week is calculated by summing up the total number of attendees and dividing by the number of classes. The mean attendance for last week was 21.

To calculate the mean number of people attending the spinning class each day, you would add up the total number of people for the week and then divide by the number of classes.

The given numbers are:

So the sum of the attendees is: 13 + 23 + 24 + 31 + 14 = 105

The mean is then calculated by dividing the total by the number of days, which is 5 in this case:

Mean = Total ÷ Number of Days = 105 ÷ 5 = 21

So, the mean number of people in each class last week was 21.

Answer:

Option D

Yes 0.4

Step-by-step explanation:

A sequence is said to be arithmetic if there is a pattern as

nth term is got by adding d to n-1th term.

d = common difference

The sequence will look like

a, a+d,a+2d, a+3d,......

where I term= a and each time d is added to get the next term.

Our given sequence is

-0.3, 0.1, 0.5, 0.9, …

Let us find difference between Ii and I term

=0.1-(-0.3) = 0.4

Similarly iii term - ii term

=0.5-0.1 =0.4

and iv term - iii term = 0.9-0.5 = 0.4

Hence confirmed that this is an arithmetic sequence with I term =-0.3 and common difference = 0.4

The formula of a midpoint:

[tex]M_{AB}\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)[/tex]

We have:

[tex]A(8,\ 4)\to x_A=8,\ y_A=4\\B(12,\ 2)\to x_B=12,\ y_B=2[/tex]

Substitute:

[tex]\dfrac{8+12}{2}=\dfrac{20}{2}=10\\\\\dfrac{4+2}{2}=\dfrac{6}{2}=3[/tex]

Let's first recall what is known as the Midpoint formula we have, so by the Midpoint formula, we know that, the midpoint of any line segment joining the points [tex]{\bf{A(x_{1},y_{1})}}[/tex] and [tex]{\bf{B(x_{2},y_{2})}}[/tex] is given by

Now, if we assume our points to be A(8,4) and B(12,2) and the midpoint being M, then we will be having :

[tex]{:\implies \quad \sf M=\bigg(\dfrac{8+12}{2},\dfrac{4+2}{2}\bigg)}[/tex]

[tex]{:\implies \quad \sf M=\bigg(\dfrac{20}{2},\dfrac{6}{2}\bigg)}[/tex]

[tex]{:\implies \quad \boxed{\bf{M=(10,3)}}}[/tex]

Hence, the required Midpoint is (10,3)

Hello!

To find the midpoint of the line segment, use the formula: [tex](\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2})[/tex]. In simpler terms, we are finding the average of the two points.

We can assign [tex]x_{1}[/tex] and [tex]y_{1}[/tex] to the point (5, 8), and (-1, 6) to  [tex]x_{2}[/tex] and  [tex]y_{2}[/tex].

[tex](\frac{5+(-1)}{2}, \frac{8+6}{2}) = (\frac{4}{2}, \frac{14}{2}) = (2, 7)[/tex]

Therefore, the coordinates of the midpoint of the line segment is (2, 7).

Final answer:

The coordinates of the midpoint of the line segment with endpoints (5,8) and (-1,6) are (2,7).

Explanation:

To find the coordinates of the midpoint of a line segment, we can use the midpoint formula which states that the x-coordinate of the midpoint is the average of the x-coordinates of the two endpoints, and the y-coordinate of the midpoint is the average of the y-coordinates of the two endpoints.

Using the formula, we can find the midpoint of the line segment with endpoints (5,8) and (-1,6).

x-coordinate: (5 + (-1)) / 2 = 4 / 2 = 2

y-coordinate: (8 + 6) / 2 = 14 / 2 = 7

Therefore, the coordinates of the midpoint of the line segment are (2,7).
