An Impressionist painting increases in value
at an average rate of 9% a year. If the origi-
nal cost of the painting to the Museum of
Art was $1500, what was the value of the
painting (to the nearest dollar) at the end of
a 20-year holding period?
Answer:
A = $8406.6
Step-by-step explanation:
Given:
Average rate [tex]r=9\%[/tex]
Initial cost of painting [tex]a = \$1500[/tex]
Time [tex]t = 20\ years[/tex]
We need to find the final amount of painting at the end of a 20-year.
Solution:
Using Exponential Growth rate formula as:
[tex]A = a(1+r)^t[/tex] ----------(1)
Where:
A = Final amount
a = Initial amount.
r = Rate as a decimal.
t = Time.
Now, we substitute all given values in equation 1.
[tex]A = 1500(1+0.09)^{20}[/tex]
[tex]A = 1500(1.09)^{20}[/tex]
Substitute [tex]1.09^{20} = 5.60[/tex] in above equation.
[tex]A = 1500\times 5.60[/tex]
A = $8406.62
Therefore, value of the painting at the end of a 20-year A = $8406.6
Cleo bought 10 feet of ribbon for costumes. He used 2 feet of ribbon last week. He cut of the remaining ribbon into one- sixth foot pieces. How many pieces of ribbon does Cleo have?
Answer:
48 pieces
Step-by-step explanation:
Given:
Cleo bought 10 feet of ribbon.
He used 2 feet of ribbon last week.
He cut of the remaining ribbon into one- sixth foot pieces.
Question asked:
How many pieces of ribbon does Cleo have ?
Solution:
Total length of ribbon = 10 feet
He has used length of ribbon = 2 feet
Remaining length of ribbon = 10 - 2 = 8 feet
He cut remaining ribbon into = [tex]\frac{1}{6}foot[/tex]
Number of pieces of ribbon = [tex]8\div\frac{1}{6}[/tex]
= [tex]8\times6 = 48 pieces[/tex]
Therefore, Cleo have 48 pieces of ribbon.
Siven that f(x)=x2 - 7 and g(x)= 4 - x, find (f - g)(1), if it exists.
Answer:
- 9
Step-by-step explanation:
Note that (f - g)(x) = f(x) - g(x)
f(x) - g(x)
= x² - 7 - (4 - x)
= x² - 7 - 4 + x
= x² + x - 11
Thus
(f - g)(1) ← substitute x = 1 into (f - g)(x)
= 1² + 1 - 11
= 1 + 1 - 11
= - 9

How do I solve these using the elimination method:
x+y+z=20
13x+0y+6z=132
150x+90y+139z=2601
Answer:
(x=6,y=5,z=9)
Step-by-step explanation:
The given system is
x+y+z=20 ------>(1)
13x+0y+6z=132 ------->(2)
150x+90y+139z=2601------>(3)
Make y the subject in the first equation to get: [tex]y=20-x-z-------(4)[/tex]
Put equation (4) in equation (3) to get:
150x+90(20-x-z)+139z=2601
150x+180-90x-90z+139z=2601
60x+49z=801---->(5)
We solve equation (2) and (5) simultaneously
13x+6z=132 ------->(2)
60x+49z=801---->(5)
Make x the subject in equation (2) to get:
[tex]x=\frac{132-6z}{13}[/tex]
Put it in (5)
[tex]60(\frac{132-6z}{13})z+49z=2601[/tex]
[tex]\frac{277z+7920}{13}=801[/tex]
[tex]277z+7920=10413[/tex]
[tex]277z=2493[/tex]
[tex]z=9[/tex]
[tex]x=\frac{132-6*9}{13}=6[/tex]

Answer:
y=42 degrees.
Step-by-step explanation:
The sum of angles in a triangle = 180 degrees.
One angle in that small triangle is y, one is 48, and one is unknown.
The sum of angles on one line is 180 degrees.
One of the angles on the line that unknown angle lies on is 90 degrees, so the unknown angle is 90 degrees, too.
90 + 48 = 138
180 - 138 = 42.
Angle A and Angle B are supplementary angles. If
mZA = (2x + 26)° and m
And angle B = (x + 25)°, then find the measure
of angle B.
Briefly describe whether or not a disconnected graph is always a bad thing.
Whether a disconnected graph is problematic depends on its application. In network theory, it might represent critical separations, but in connected systems like transportation, it signifies issues. The context, such as economic, ecological, or psychological networks, determines its value.
Explanation:A disconnected graph is not inherently a bad thing; its value depends on the context in which it is used. For example, in network theory, a disconnected graph might accurately represent separate clusters within a network, indicating areas that do not communicate or interact with each other. This could be critical for understanding the structure of social networks, the Internet, or ecological systems. On the other hand, in applications where connectivity is essential, such as in the design of transportation or communication networks, a disconnected graph could signify a problem that needs addressing. Thus, it's crucial to consider the specific needs of the application or system being analyzed.
Economists use graphs to depict connections and costs, highlighting the importance of understanding the underlying story a graph tells. The fact that all graphs have a genealogy and a narrative is essential in interpreting them correctly. For instance, a graph showing disconnected components in an economic network could indicate areas of inefficient resource allocation or potential opportunities for improvement.
Ultimately, whether a disconnected graph is seen as a disadvantage depends on the goals of the analysis. In ecological studies, reconnecting fragmented landscapes is often beneficial, although careful planning is needed to avoid drawbacks. Similarly, in the context of relational connectivity theory (RCT), connectivity and the loss thereof have profound implications on wellbeing, demonstrating that the concept of dis/connection transcends mathematical graphs and touches on broader socio-psychological themes.
One quart of water-resistant paint covers 75 square feet. A swimming pool is in the shape of a rectangular prism with a length of 20 feet, a width of 10 feet, and a height of 5 feet. How many quarts should you buy to paint the swimming pool with two coats of paint?
18.66 quarts of paint is needed to paint the swimming pool with two coats of paint
Solution:
Given that,
A swimming pool is in the shape of a rectangular prism
Length = 20 feet
Width = 10 feet
Height = 5 feet
Find the surface area of prism
[tex]A=2(wl+hl+hw)[/tex]
Where, "l" is the length and "w" is the width and "h" is the height
[tex]A = 2(10 \times 20 + 5 \times 20 + 5 \times 10)\\\\A = 2(200+100+50)\\\\A = 2 \times 350\\\\A = 700[/tex]
Thus surface area area of prism is 700 square feet
Given that,
One quart of water-resistant paint covers 75 square feet
Therefore,
1 quart paint = 75 square feet
x quart = 700 square feet
This forms a proportion
[tex]1 \times 700 = 75 \times x\\\\x = \frac{700}{75}\\\\x = 9.33[/tex]
Thus 9.33 quarts of paint is needed to cover 700 square feet
How many quarts should you buy to paint the swimming pool with two coats of paint
For two coats of paint we need = 9.33 + 9.33 = 18.66 quarts of paint
Answer:this answer is incorrect.
You can’t paint the top of the pool.
You need to subtract 2 of the top layer’s surface area. The answer is you would need to buy 14 quarts.

how many triangles can be drawn with side lengths of 3 inches, 5 inches, and 6 inches???
Answer:
4 congruent triangles
Step-by-step explanation:
since there is no one of the sum of two sides is less then the third side, so it's possible to form a triangle
Use straightedge and compass, it can draw 4 triangles at a common base
The number of triangles that can be drawn with side lengths of 3 inches, 5 inches, and 6 inches is 1 triangle due to the triangle inequality theorem.
To determine the number of triangles, we can use the triangle inequality theorem. For a triangle to exist, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In this case, 3 + 5 is less than 6, so only 1 triangle can be formed.

What is the measure of angle x?
Enter your answer in the box.
Answer:
Step-by-step explanation:
Just like regular numbers, angles can be added to obtain a sum, perhaps for the purpose of determining the measure of an unknown angle. Sometimes we can determine a missing angle because we know that the sum must be a certain value. Remember -- the sum of the degree measures of angles in any triangle equals 180 degrees. Below is a picture of triangle ABC, where angle A = 60 degrees, angle B = 50 degrees and angle C = 70 degrees.
The angles of this triangle are 50, 60, and 70 degrees.
If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry. We can use this idea to find the measure of angle(s) where the degree measure is missing or not given.
Answer:
48 degrees
Step-by-step explanation:
The sum of 42 and x should get 90 degrees, so if you subtract 42 from 90 you get 48.

Find the lateral surface area of the figure. A 798 B 210 C 816.8 D 69.7
the lateral surface area of the figure is 660 sq ft
(but the answer is not matching with the options)
Step-by-step explanation: this figure is called cylinder. the lateral surface area means the area of curved surface.
here the diameter is 10 ft
so radius = diameter/2 = 10/2 ft = 5ft
again, height = 21ft
now the lateral surface area = perimeter of the circular surface X height
= 2X pie X r X h ( here r is the radius and h is height and we will take pie as 22/7)
= 2 X (22/7) X 10 X 21 sq ft
= 2 X 22 X 5 X 3 sq ft
=660 sq ft
( suggest you to recheck the options)
Given :-
Diameter :- 10ft. , radius :- 5ft. Height:- 21 ft.To find :-
