A chair cost $250 last year and $175 this year by what percent did the price decrease?
Answer:
I believe it is 50% decreased, not sure
Step-by-step explanation:
Answer:
30%
Step-by-step explanation:
in order to find the percentage of the price decrease,we must find the difference between the prices
250-175=75
the price has dropped 75$
to find the percentage, we do 75/250
which can be simplified to 3/10 or 30%
We can check this by finding 30% of 250 which is 75
75=75
A 14 ft ladder is used to scale a 13 ft wall. At what angle of elevation must the laxder be situated in order to reach the top of the wall?
Answer:
The angle of elevation is equal to 68.2 degrees
Step-by-step explanation:
As you can see from the image below we are trying to find the angle on the bottom right.
We know that the hypotenuse is equal to 14 and we know that the opposite is equal to 14. This means that we will be using Sine.
sin x = 13/14
divide:
sin x = 0.9285714286
now we need to use sin^-1
sin^-1 (0.9285714286) = 68.21321071
Round 68.21321071 to the nearest tenth:
68.2
The angle of elevation is 68.2 degrees!
Answer:
[tex]\theta \approx 68^\circ[/tex]
Step-by-step explanation:
Trigonometry
The ladder, the wall, and the ground form a right triangle, where the ladder is the longest side (hypotenuse).
The trigonometric ratios stand on right triangles and can be used to relate side lengths with angles.
The angle of elevation, formed by the ladder and the ground has the height of the wall as the opposite side. Thus we can use the sine ratio, defined as:
[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
[tex]\displaystyle \sin\theta=\frac{13}{14}[/tex]
Solving:
[tex]\displaystyle \theta=\arcsin \frac{13}{14}[/tex]
Calculating:
[tex]\mathbf{\theta \approx 68^\circ}[/tex]

Answer:
100, 70, 80, 56
Explanation:
Look at attached image!
In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.
The number in the 4 sections are 100, 80, 70, and 56.
A 2 x 2 array that shows the problem 18 x 17.
2 x 2 array has four blockers or magic quadrants, the matrix diagram is a simple square divided into four equal quadrants.
18 = 10 +8
17 = 10 +7
18 x 17 = 306
In the 2 x 2 array : 100+80+70+56 = 18 x 17 = 306
Therefore, In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.

Find the measure of the angle which is double of its complement angle
Answer:
60°
Step-by-step explanation:
Complementary angles add to 90°, so if x is double its complement, then x + (1/2)x = 90. Doing the algebra gets you to x = 60. You know that answer is correct because 60 is double 30, which is its complement.

The graph of which of the following equations contains the points (2,3) and (3,2)
Answer:
[tex] y = 5 - x [/tex]
Step-by-step explanation:
The graph of the equation that will contain the points (2, 3) and (3, 2) is the graph that has a slope value that is equivalent to the slope value of the line running through the two points.
Slope of the line running through (2, 3) and (3, 2):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 3}{3 - 2} = \frac{-1}{1} = -1 [/tex].
Slope (m) = -1.
The equation, [tex] y = 5 - x [/tex] , is given in the slope-intercept form, which means it has a slope value of -1. I.e. the term "-x" is equivalent to -1x. So therefore, the graph of the equation that contains the points (2, 3) and (3, 2) is [tex] y = 5 - x [/tex].
Which property is illustrated by the equation 6+(4+x)=6+(x+4)?
1.) Associative property of addition 2.) Associative property of multiplication
3.) Distributive Property 4.) Commutative property of addition
The property illustrated by the equation 6 + (4 + x) = 6 + (x + 4) is the commutative property of addition.
The commutative property of addition states that the order in which numbers are added does not affect the result. In this equation, both sides of the equation involve adding numbers, and the numbers being added are the same: 6, 4, and x.
The equation shows that regardless of whether we add 4 and x first or x and 4 first within the parentheses, the final result will be the same. The commutative property of addition allows us to freely rearrange the order of the terms being added without changing the overall sum.
Therefore, The property illustrated by the equation 6 + (4 + x) = 6 + (x + 4) is the commutative property of addition.

3. Fiona opened a retirement account that has an annual yield of 6%. She is planning on retiring in 20 years. How much must she deposit into that account each year so that she can have a total of $600,000 by the time she retires?
Fiona must deposit $18,277.65 into her retirement account each year for the next 20 years in order to have a total of $600,000 by the time she retires.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
The present value of an annuity is:
PV = PMT x [(1 - (1 + r)⁻ⁿ) / r]
Where PV is the present value,
PMT is the periodic payment
r is the interest rate per period (6% per year), and
n is the number of periods (20 years).
We want to find PMT, so we can rearrange the formula to solve for it:
PMT = PV x [r / (1 - (1 + r)⁻ⁿ)]
We know that PV is $600,000, r is 6% or 0.06, and n is 20.
Plugging these values into the formula, we get:
PMT = $600,000 x [0.06 / (1 - (1 + 0.06)⁻²⁰)]
PMT ≈ $18,277.65
Therefore, Fiona must deposit $18,277.65 into her retirement account each year for the next 20 years in order to have a total of $600,000 by the time she retires.

Choose the function represented by the data.
O f(x) = h2 + 4h + 80
O f(x)=5h2 -5h + 13
O f(x) = h +50h2 - 120h
O f(x) = 5h3 - 50h2 + 130h
Answer:
Option (4)
Step-by-step explanation:
To solve this problem we will satisfy the polynomials given in the options with the input-output values given in the table.
Lets take a point (4, 40),
Option (1),
f(h) = h² + 4h + 80
40 = 4² + 4(4) + 80
40 = 16 + 16 + 80
40 = 112
False.
Therefore, table doesn't represent the polynomial given in option (1).
Option (2)
f(h) = 5h²- 5h + 13
40 = 5(4)² - 5(4) + 13
40 = 80 - 20 + 13
40 = 73
False.
Therefore, table doesn't represent the polynomial given in option (2).
Option (3)
f(h) = h³ + 50h² + 13
40 = 4³ + 50(4)²+ 13
40 = 64 + 800 + 13
40 = 873
False.
Therefore, table doesn't represent the polynomial given in option (3).
Option (4)
f(h) = 5h³- 50h²+ 13h
40 = 5(4)³ - 50(4)²+ 130(4)
40 = 320 - 800 + 520
40 = 840 - 800
40 = 40
True.
Therefore, given table represents this polynomial.
Option (4) will be the answer.
