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

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.

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.

Answer:
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!

Answer:
-14541 = 0
Step-by-step explanation:
Simplify each term.
121 to the power of 2
100 − 1 X 14641 = 0
1 X 14641
100 − 14641 = 0

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

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 )

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).

Josie wants to build a slide that is 15 feet long. If the angle of elevation for the side will be 30 degree, how high in feet will the top of the slide be ?
Answer: 7.5
Step-by-step explanation: draw a right triangle to represent the slide. the slide is 15 feet long, so the hypotenuse of the right triangle would be 15 feet. The angle from the bottom is 30 degrees according to the question. You want to find the angle opposite from the 30 degree angle so use sin(30). Sin=opposite/hypotenuse so sin(30)=x/15 sin(30) is 1/2 so 1/2=x/15. You multiply by 15 on both sides to get x by itself. 1/2*15=7.5
