Answer:

For the hexagon, the sum of all angles must be equal to 360. So, we have 360 divided by 6 and we have 60 and this is the angle for the hexagon. For the pentagon, again, the sum of all the angles must be equal to 360, so each angle is equal to 360/5 = 72.

The difference between 72 and 60 is equal to y which is 12.

The rule for reflecting over the Y axis is to negate the value of the x-coordinate of each point, but leave the -value the same.

A reflection is a mirror image of the shape. An image will reflect through a line, known as the line of reflection.

When a point is reflected across the Y-axis, the Y-coordinates remain the same, and the X-coordinates are transformed into their opposite signs.

Therefore, the reflection of the point (x, y) across the Y-axis is (-x, y).

A reflection of a point, a line, in the Y axis reflects the image over the Y axis to create a mirror image. In this way, the Y axis would be called the axis of reflection.

Lindsay's z - score, given the mean score, the standard deviation, and her score, is 2. 35.

To calculate a z-score, you subtract the mean from the individual score and then divide by the standard deviation.

The formula is:

z = (x - μ) / σ

Where

x is the individual score

μ is the mean

σ is the standard deviation.

So, to find Lindsay's z-score:

Answer:

t ≥ 7

Step-by-step explanation:

6t - 1 ≥ 4t + 13 ( subtract 4t from both sides )

2t - 1 ≥ 13 ( add 1 to both sides )

2t ≥ 14 ( divide both sides by 2 )

t ≥ 7

Answer:

Inequality Form: t ≥ 7

Interval Notation: [ 7, ∞ }

Step-by-step explanation:

1) Move all terms that contain "t" to the left side of the inequality by subtracting 4t from both sides.

a) 6t – 1 – 4t ≥ 13, THEN subtract 4t from 6t

b) 2t – 1 ≥ 13

2) Move terms that do not contain "t" to the right side of the inequality:

a) ADD 1 to both sides ––>  2t ≥ 13 + 1

b) ADD 13 and 1 ––> 2t ≥ 14

3) Divide each term by 2, then simplify:

= 2t/2 ≥ 14/2

Substitution table method is a method for solving systems of linear equations. It involves writing out the equations in a table with one variable per column, and then substituting one variable for the other until the equations are solved. This method can help students visualize the equations and make it easier to keep track of the values of each variable.

The substitution table method is a simple but effective way of solving systems of linear equations. It involves writing out the equations in a table with one variable per column. Then, one variable is substituted for the other until the equations are solved. This method is useful because it provides a visual way of keeping track of the values of each variable. It can also help students understand which variable values need to be substituted into which equations. Once the table is complete, the equations can be solved by using the values of the variables in the table. This method can be used to solve both two-variable and multi-variable systems of linear equations.

With the help of the given equation, we know that the required slope is (A) 3/8.

In math, the gradient of a line is a number that tells you how steep it is and in which direction it goes in.

The point-slope form is a way of writing equations (y-y₁=m(x-x₁)) to emphasize the slope and a point on the line that isn't the y-intercept.

To highlight the same line's slope and y-intercept, you can rewrite the equation in slope-intercept form (y=mx+b).

So, we have the equation:

-3x + 8y = 12

Calculate the slope as follows:

We need to change it into a more general format.

-3x+8y=12

⇒ 8y = 3x+12

⇒ y = 3x/8+12/8

⇒ y = 3x/8+3/2

If you look at it in terms of y = mx+c, the m would be 3/8.

Therefore, with the help of the given equation, we know that the required slope is (A) 3/8.

The area of sector in question 9 is 141.87 ft² and the area of sector in question 10 is 107.70 m².

A circle is a collection of points that are all equally distance from the circle's centre. The radius is the usual distance a circle travels from its centre to its point. The circle's centre (o) and radius (r) serve as its definition (r).

A sector is referred to as a component of a circle made up of the circle's arc and its two radii. It is a section of the circle made up of the arc's circumference and the radii of the circle at its ends.

Given in question 9, r = HK = 25 ft

angle of sector = 26°

so the area of sector A₉ = (26°/360°)π*r²

⇒ A₉ = (26°/360°)* 22/7 * (25)²

⇒ A₉ = (26°/360°)* (22 * 625)/7

⇒ A₉ = 357,500/2520

⇒ A₉ = 141.87 ft²

Given in question 10, SR = 26 m

⇒ r = ST = SR/2

⇒ r = 26/2 = 13 m

angle of sector = 73°

so the area of sector A₁₀ = (73°/360°)π*r²

⇒ A₁₀ = (73°/360°)* 22/7 * (13)²

⇒ A₁₀ = (73°/360°)* (22 * 169)/7

⇒ A₁₀ = 271,414/2520

⇒ A₁₀ = 107.70 m²

Answer:

$11.05

Step-by-step explanation:

First, you make the percent into a decimal

35% - 0.35

Next, you multiply 17 and 0.35

17* 0.35= 5.95

Then, you subtract the discount which is $5.95 from $17

17-5.95= 11.05

So, the answer is $11.05

Hope this helps :)

Answer: $11.05

Step-by-step explanation:

First how much 35% of 17:

35% = 0.35

0.35 x 17 = 5.95

Next, subtract this discount off of the total:

17 - 5.95 = 11.05

  [tex]A. \;\;b \;is \;greater[/tex]

  [tex]B.\;\;a = 1, b = -4[/tex]

  [tex]C.\;\;a = 6, c = 20[/tex]

Step-by-step explanation:

Part A

We have the relationship

[tex]b = 6a - 10[/tex]

When [tex]a[/tex] is [tex]-2[/tex], the value of [tex]b[/tex] is

[tex]b = 6(-2) -10 = -12 -10 = -22[/tex]

The corresponding value of [tex]c[/tex] for [tex]a = - 2[/tex] is -[tex]21[/tex]

[tex]-21[/tex] is greater than [tex]-22[/tex] so answer is :  [tex]b[/tex]  is greater

Part B

When [tex]c[/tex] is [tex]6[/tex], we see that the value of [tex]a[/tex] from the table is [tex]1[/tex]

The corresponding value of b is:

[tex]b = 6(1) - 10 = 6 - 10 = -4[/tex]

Part C

When [tex]b = 26[/tex], plugging this into the equation[tex]b = 6a - 10[/tex] we get

[tex]26 = 6a - 10\\\\26 + 10 = 6a\\\\36 = 6a\\\\[/tex]

or

[tex]6a = 36[/tex] giving [tex]a = 36/6 = 6[/tex]

For [tex]a = 6[/tex], from the table we see that the corresponding value of [tex]c = 20[/tex](ANS)

You could compare the ounces or weight, the price per unit, or overall quality.

Step-by-step explanation:

You could use the ounce/weight to check which weighs more, or has more in it. Then figure out which is more reasonable. You could use the price per unit, and the ounce/weight because the price per unit/ price per ounce could be more expensive, or less expensive and make more sense to buy. Or you could just use overall quality. You can have an item with more in it, but have lower quality contents, when you could have a smaller amount with better quality contents, which might cost a little more.\

The length of LN is approximately 101.12 cm.

What is the length of the hypotenuse?

In a right triangle, the hypotenuse is the side opposite to the right angle and it is the longest side of the triangle. The length of the hypotenuse can be found using the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides.

In a right triangle, the length of the hypotenuse is given by the Pythagorean theorem: c^2 = a^2 + b^2.

In this case, we are given that LN is the hypotenuse, and LP and MN are the other two sides.

We are also given that LP = 100 and MN = 15, and that angle PLN = PNL which means that the triangle is a right triangle.

We can use the Pythagorean theorem to find the length of LN:

LN^2 = LP^2 + MN^2

LN^2 = 100^2 + 15^2

LN^2 = 10000 + 225

LN^2 = 10225

LN = √10225

LN ≈ 101.12 cm

So the length of LN is approximately 101.12 cm.

To find the midpoint between any two points in a plane using only their coordinates, you can use the midpoint formula. The midpoint formula is:

(x,y) = ((x1 + x2) / 2, (y1 + y2) / 2)

Where (x1, y1) and (x2, y2) are the coordinates of the two points, and (x,y) are the coordinates of the midpoint.

For example, if we have two points (-2,8) and (4,10)

(x,y) = ((-2 + 4) / 2, (8 + 10) / 2)

(x,y) = (1,9)

The midpoint of the given points (-2,8) and (4,10) is (1,9).

It's worth noting that this formula can be adapted for three-dimensional points, where the midpoint formula would be

((x1 + x2)/2, (y1 + y2)/2, (z1 + z2)/2)

A special example of the polynomial remainder theorem is the Factor theorem. So, according to the factor theorem, a polynomial has a factor if and only if: If and only if f (M) = 0, the polynomial x-M is a factor of the polynomial f(x).

Here,
Given equation of function f(x) = |x| + 2

The above function is an aboslute function, so in order to translate the function right, the function after transformation will be as |x - 3|  + 2, we subtract 3 from x to translate in the horizontal x-axis.
Now,
Add + 1 to the function to translate it 1 unit up,
