Which polygon has an interior angle sum of 1080°?
Answer:
The polygon with an interior angle sum of 1080° is an octagon or a polygon with 8 sides. We are given that the interior angle sum of our polygon
Step-by-step explanation:
Sorry if it's wrong.
Answer:
Step-by-step explanation:
Remark
First of all, you need a regular polygon, otherwise the question can have all sorts of interior angles. The standard way to solve this is set up an equation that looks like this.
(n - 2)*180 = 1080 Divide by 180
(n - 2) = 1080/180
n - 2 = 6 Add 2 to both sides.
n = 6 + 2
n = 8
Conclusion
So an 8 sided figure has 8 interior angles that add up to 1080 if the 8 sided figure is regular.

Discriminant 9v^2+v+5=0
Answer:
-179, since it is negative then there are no real roots
Step-by-step explanation:
b²-4ac is the discriminant formula
9v² + v + 5 = 0 ∴ a = 9, b = 1, c = 5
1² - 4(9)(5) = -179
P is the point (16,9) and Q is the point (22. 24).
(a) Find the equation of the line perpendicular to PQ that passes through the point (5, 1).
Give your answer in the form y=mx+c.
(b) N is the point on PQ such that PN=2NQ. Find the co-ordinates of N.
Answer:
see explanation
Step-by-step explanation:
(a)
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (P(16, 9) and (x₂, y₂ ) = Q(22, 24)
[tex]m_{PQ}[/tex] = [tex]\frac{24-9}{22-16}[/tex] = [tex]\frac{15}{6}[/tex] = [tex]\frac{5}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{5}{2} }[/tex] = - [tex]\frac{2}{5}[/tex] , then
y = - [tex]\frac{2}{5}[/tex] x + c ← is the partial equation
To find c substitute (5, 1) into the partial equation
1 = - 2 + c ⇒ c = 1 + 2 = 3
y = - [tex]\frac{2}{5}[/tex] x + 3 ← equation of perpendicular line
(b)
Given PN = 2NQ , then N sections PQ in the ratio 2 : 1
Using the Section formula to find coordinates of N
N = ( [tex]\frac{16(1)+22(2)}{1+2}[/tex] , [tex]\frac{9(1)+24(2)}{1+2}[/tex] )
= ( [tex]\frac{16+44}{3}[/tex], [tex]\frac{9+48}{3}[/tex] )
= ( [tex]\frac{60}{3}[/tex], [tex]\frac{57}{3}[/tex] )
= (20, 19 )
6. Sales associates at a local clothing
store eam a 2% commission on the
clothes they sell if an associate earned
$50 in commission, what was the value
of her sales? Explain how you can
check your answer.
Answer quick PLZZ no website
Answer:
$2500
Step-by-step explanation:
Given data
Percent commission from sale= 2%
We are told that an associate earned $50 from sales
Let the amount of the sales be x
so
2/100*x= 50
0.02x=50
Divide both sides by 0.02
x=50/0.02
x=2500
Hence the sales made was $2500

Corresponding angles
Step-by-step explanation:
A corresponding angles is, and I quote, "the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal." (See image below)
So, looking at our words and graph, 5 and 1 are corresponding angles!

Find the measure of b and a. (type the number of the angle measure ONLY)
Answer:
Step-by-step explanation:
A straight line has 180 degrees.
43 + b + 50 = 180 Collect like terms
b + 93 = 180 Subtract 93
b = 180 - 93
b = 87
a + b + 75 = 180 All triangles have 180 degrees.
a + 87 + 75 = 180 Combine like terms
a + 162 = 180 Subtract 162 from both sides
a = 180 - 162
a = 18

A store has clearance items that have been marked down by 60%. They are having a sale, advertising an additional 15% off clearance items. What percent of the original price do you end up paying?
Answer: 34%
Step-by-step explanation:
Given
Price is marked down by 60% with an additional discount of 15% on the marked down price
Suppose x is the original price of the item
After marking down, it is
[tex]\Rightarrow x-x\times 0.6=0.4x[/tex]
after additional discount it is
[tex]\Rightarrow 0.4x(1-0.15)=0.4x\times 0.85=0.34x[/tex]
Effective discount on the item is
[tex]\Rightarrow \dfrac{x-0.34x}{x}\times 100=66\%[/tex]
Thus, a person is paying [tex]100-66=34\%[/tex] of the original price

How would this triangle be classified?
Answer:
D (Isosceles Obtuse)
Step-by-step explanation:
Since 2 of the sides are the same length, that would make the triangle an isosceles.
Since 1 of the angles are over 90 degrees, that would make the triangle obtuse.
This makes the triangle an isosceles obtuse triangle.

A confidence level of 95% means: 95% of the time, sample percentages will fall above the mean. 95% of the time, population data will fall between 149.61 and 150.39. the mean of 95% of the adults in the sample was 150.
Answer:
B
Step-by-step explanation:
95% of the time, population data will fall between 149.61 and 150.39.
A confidence level of 95% means 95% of the time, population data will fall between 149.61 and 150.39. The correct answer would be an option (B).
What is the sample?A sample is a subset of data drawn from a larger population by a researcher using a predetermined selection process. These components are referred to as sample points, sampling units, or observations.
The second statement, "95% of the time, population data will fall between 149.61 and 150.39," is more accurate in terms of what a 95% confidence level implies.
When you conduct a sample survey, you can calculate a confidence interval, which is an estimate of the range of values that the population parameter is likely to fall within.
If the confidence level is 95%, it means that if you were to repeatedly sample the population and construct a confidence interval each time, 95% of those intervals would contain the true population parameter.
Thus, the correct answer would be option (B).
