The final discounted price is $18.6
Step-by-step explanation:
In this problem we have to decrease the value of $20 by 7%.
First of all, we have to calculate the 7% of $20. We can do it as follows:
[tex]d=\frac{7}{100}\cdot 20 = 1.4[/tex]
This means that the 7% of $20 is 1.4$.
Now we want to decrease the original value by 7%, so we calculate the difference:
[tex]f=20 - d = 20-1.4=18.6[/tex]
So, the final discounted price is $18.6

The Endeavor, a space shuttle, has speeds of about 27,404 feet per second. Convert the speed into kilometers per hour and miles per hour.
Answer:
Speed of shuttle in km per hr = 30069.86 km per hr
Speed of shuttle in miles per hr = 18643.31 miles per hr
Step-by-step explanation:
Speed of space shuttle in feet per second= 27,404 feet per second
As
One foot per second = 1.09728 kilometers per hour,
The speed in kilometers per hour is equal to the feet per second multiplied by 1.09728
So
To find out speed of shuttle in km per hour we will mutilpy our speed with 1.09728
27404 ft per sec = 27404x 1.09728 km per hr
speed of shuttle in km per hr = 30069.86 km per hr
Now
As we know 1km = 0.621371 miles
To convert this speed into miles per hr we will multiply our speed with 0.621371
30069.86 km per hr = 30069.86x0.621371 miles per hr
speed of shuttle in miles per hr = 18643.31 miles per hr

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.

Solve for u. -24 = u ÷ 6
u = ____
The value of u is -144
Solution:
Given that,
[tex]-24 = u \div 6[/tex]
We have to solve for "u"
From given,
[tex]-24 = u \div 6[/tex]
Convert the division problem into multiplication, by changing the division sign to multiplication sign. Then invert the number to right of division sign
Thus we get,
[tex]-24 = u \times \frac{1}{6}\\\\\frac{u}{6} = -24[/tex]
Isolate for u
[tex]u = -24 \times 6\\\\On\ multiplying\ both\ we\ get\\\\u = -144[/tex]
Thus the value of u is -144

Answer: D
Step-by-step explanation: In this problem, we want find the difference between each of the x-term and each of the y-terms.
Let's begin with the x-terms.
Notice that the difference between 1 and 0 is +1, the difference between 2 and 1 is +1, the difference between 3 and 2 is +1, and the difference between 4 and 3 is +1.
Now, looking at the y-terms.
The difference between 5 and 2 is +3, the difference between 8 and 5 is +3, the difference between 11 and 8 is +3, and the difference between 14 and 11 is +3.
To write an equation, we need to know the multiplier and the base.
The multiplier will be equal to the change in y over the change in x.
The change in y is always +3 and the change in x is always +1.
So we have [tex]\frac{+3}{+1}[/tex] which is equal to +3.
This means that the multiplier is equal to 3.
Next, we want to find the base or the value of y when x is equal to 0. The base is equal to when x is equal to 0.
Now to write an equation from the data in the table, we begin with the equation y = mx + b where m is the multiplier and b is the base.
We know that the multiplier is 3 and the base is 2.
So we have y = 3x + 2.
So your answer is D.

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.

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 :-

20 m
atio
Answer: [tex]d = 20m[/tex]
Step-by-step explanation:
The formula for calculating the area of square is given by :
Area = [tex]s^{2}[/tex]
where s is the length of a side , that is
200 = [tex]s^{2}[/tex]
Therefore :
[tex]s = \sqrt{200}[/tex]
[tex]s = 10\sqrt{2}[/tex]
Recall that the diagonals of a square meet at right angle , then we can calculate the diagonal by Pythagoras theorem , that is
[tex]d^{2}[/tex] = [tex](\sqrt{10})^{2}[/tex] + [tex](\sqrt{10})^{2}[/tex]
[tex]d^{2} = 200 + 200[/tex]
[tex]d^{2} = 400[/tex]
[tex]d = \sqrt{400}[/tex]

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.
