Answer:
$6.882.5 poundsStep-by-step explanation:
1. In this case, it appears that "some" means "4". The total cost of 4 place mats and 4 napkin rings is apparently ...
$17.16 +10.36 = $27.52
Then the total cost of 1 of each is 1/4 this amount, or ...
$27.52/4 = $6.88

How many sides does a regular polygon have if one interior angle measures 144°
Answer: 10 sides
Step-by-step explanation:
You can always use the given formula to calculate but I (personally) find it much easier to calculate the number of sides using the exterior angle.
To calculate the exterior angle, it is 180 - the interior angle.
In this example, the exterior angle would be 180-144 = 36°
Because it is a regular polygon, we know that all the angles in the shape are the same.
In all polygons, the exterior angles always add up to 360 degrees.
So divide 360 by 36 (the size of each exterior angle), and you get 10.
360/36 = 10

What is the value of k?
1/2k + 6 = 4k - 8
Answer:
k=4
Step-by-step explanation:
[tex] \frac{1}{2} k - \frac{4}{1} k = - 8 - 6[/tex]
[tex] \frac{(1 \times 1) - (4 \times 2)}{(2 \times 1)} k = - 14[/tex]
[tex] \frac{1 - 8}{2}k = - 14[/tex]
[tex] - \frac{7}{2} k = - 14[/tex]
[tex] \frac{ - \frac {7}{2} }{ - \frac{7}{2} }k = \frac{ - 14}{ - \frac{7}{2} } [/tex]

The sum of an interior angle and its exterior angle is ___ for all regular polygons.
Answer:
180
Step-by-step explanation:
The sum of the measures of the interior angles of a polygon with n sides is (n – 2)180. If you count one exterior angle at each vertex, the sum of the measures of the exterior angles of a polygon is always 360°.

a line has a slope of 7/10 and a y intercept of (0,-4) what is the equation of the line in standard form
Considering the definition of a line, the equation of the line in standard form is y - 7/10x= -4
What is Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.The standard form of a linear equation is Ax + By = C. In this type of equation, x and y are variables and A, B, and C are integers.
Equation in this caseIn this case, you know:
A line has a slope of 7/10.A line has a y-intercept of (0,-4).So, the line can be expressed as:
y=7/10x -4

What are the more appropriate measures of center and spread for this data
set?
Except Option - A all satisfy the more appropriate measures of center and spread for the data that is median and IQR.
Given that,
We have to find what are the more appropriate measures of center and spread for data.
We know that,
Mean, median, and mode are the three central tendencies, and median is the more accurate indicator.
This is because
i) Extreme values affect the mean.
ii) If there are more outliers, the mean is in error.
iii) Means that are biassed to the right or left may not accurately reflect the nature of the data.
However, median is preferable to mean because it represents the center entry and is unaffected by extreme items or outliers.
Since extreme items will show higher standard deviation and some outliers may be misleading, IQR is a superior spread measurement tool. However, IQR provides an excellent idea.

Find m
Answer:
m<N = 32°
Arc NQ = 106°
Step-by-step explanation:
✔️Find m<N:
Inscribed angles theorem, we would have;
m<N = ½(arc MP)
arc MP = 64°
Substitute
m<N = ½(64°)
m<N = 32°
✔️Find measure of arc NQ:
m<P = ½(arc NQ) => inscribed angle theorem
53° = ½(arc NQ)
Multiply both sides by 2
2*53° = arc NQ
106° = arc NQ
Arc NQ = 106°

p = 10
p = 5
p = 0.5
p = 0.1
The constant of proportionality is 10 for the proportional relationship shown in the graph.
What is the constant of proportionality?The constant of proportionality is the constant value of the ratio of two proportional values. A proportionality relation exists between two changing quantities when either their ratio or product gives a constant.
The proportional relationship is shown in the given graph.
As per the given graph, we take two points (1, 10) and (2, 20)
So, the constant of proportionality will be as:
⇒ (20 - 10)/(2-1)
⇒ 10/1
⇒ 10
