Which of the following is an irrational number?
1. 1,483,292. 2. 14/17. 3. 0.100100010000... 4. 0
Answer:
The correct option is;
0.100100010000...
Step-by-step explanation:
An irrational number in mathematics are the subset of real numbers that are not rational numbers such as √2, π, e. As such it is not possible to express an irrational number as a ratio of two integers, or expressed in the form of a simple fraction.
The decimal portion of the expression of an irrational number are non periodic and they do not terminate. Transcendental, which are non algebraic, numbers are all irrational numbers
In the question, the number 0.100100010000... has non terminating non recurring decimals and is therefore an irrational number.

Step-by-step explanation:
f (x)=5x+1
Hence, In order to find f (-3), we must find the value of 5×-3 +1
Hence, Substituting x=-3,
p (-3)=5×-3 +1
= -15+1
= -14
What is the 3rd term of the linear sequence below? 22 18, 14, 10, 6
Answer:
As we can see, what we are doing is substracting 4 from one term to the next:
22 - 4 = 18
18 - 4 = 14
14 - 4 = 10
10 - 4 = 6
Knowing this and that we start on 22, we can say that for n term we have:
[tex]22-4(n-1)[/tex]
So, if we're searching the thirs term, we replace n by 3 (we can also see it in the question):
[tex]22-4(n-1)[/tex] = [tex]22-4(3-1) = 22-4*2 = 22 - 8 = 14[/tex]
So the third term is 14.

Solve for P if E = 2.50 and r = 2.00 given that E = P4πr2
Answer:
P = 0.05
Step-by-step explanation:
E = P4πr²
2.50 = P4π(2)²
2.50 = P4π4
2.50 = P(50.265)
P = 0.05
During a onemonth period, a car company's stock price went from $99.24 to $45.19 per share.
The change in the price of the stock is
dollars.
The change in price stock is $54.05.
How to calculate change in any quantity?First: work out the difference (increase or decrease) between the two numbers you are comparing.
Increase or decrease = New Number - Original Number.
initial price= $99.24
final price= $45.19
So, Change in stock = final price- initial price
=$45.19 - $99.24
=-$54.05
Hence, the price decrease in $54.05.

Solve for z. –2(z − 9) = 2
Hi there! :)
Answer:
[tex]\huge\boxed{z = 8}[/tex]
-2(z - 9) = 2
Divide both sides by -2:
-2(z - 9) / (-2) = 2/ (-2)
z - 9 = -1
Add 9 to both sides:
z = -1 + 9
z = 8.
what is the value of x if length is 3x-1 and width is x and the perimeter is 84
Answer:
x = 10.75
Step-by-step explanation:
To find the value of x, we need to know the equation for the perimeter of a rectangle. This equation is:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
We are given P = 84, L = 3x -1 , and W = x. Now we just plug these values in and solve for x.
P = 2L + 2W
84 = 2 ( 3x - 1 ) + 2 ( x )
84 = 6x - 2 + 2x
84 = 8x - 2
86 = 8x
86 / 8 = x
43 / 4 = x
(40 + 3) / 4 = x
10.75 = x
Hence, the value of x = 10.75.
Cheers.

Answer:
the shopkeeper made 1425₹ in profit on a particular dayStep-by-step explanation:
the total profit on 12 chairs:
12*250=3000₹
loss from selling 9 tables: 175*9=1575
total profit-total loss:
3000-1575=1425
the shopkeeper made 1425₹ in profit.
Answer:
1425 profit or 1575 loss
Step-by-step explanation:
250x12=3000 --> for the chairs
175x9=1575 --> for the tables
3000-1575=1425
You could say that he made 1425 profit or 1575 loss

Approximately 220 million tires are discarded in the U.S. each year. These tires present a disposal problem because they take up space, harbor pests, and have been known to catch fire. One tire can generate about 250,000 BTUs (1 BTU = 3 x 10-4 kWh) when it is burned. The average American home consumes about 10,000 kWh of electricity per year. How many tires would be needed to meet the annual electricity demand of ten homes for one year if the production of electricity from tires is 50% efficient?
Answer:
2667 tires
Step-by-step explanation:
One tire can generate:
250000 BTU's = 250000*3*10⁻⁴ kWh = 75 kWh electricityConsidering efficiency of 50%, one tire can produce:
75/2 = 37.5 kWh10 homes require electricity, amount of:
10000*10 = 100000 kWh per yearHow many tires can cover this demand?

Hey, there!!
Let's solve it simply.
Given,
11 - 13x - 7 - 2x = 7
Simplify the like terms.
11 - 7 - 13x - 2x = 7
4 - 15x = 7.
shifting 4 in right side.
-15x =7-4
-15x = 3
Divide 3 by -15.

Turn 5 8/25Into a decimal
Answer: 5.32
Step-by-step explanation:
8/25 as a decimal is 0.32. Add the fraction and whole number and you get 5.32
Answer:
5.32
Step-by-step explanation:
We know that the 5 in [tex]5 \frac{8}{25}[/tex] will just be a 5, so we can leave that be for now.
Since we have [tex]\frac{8}{25}[/tex], we want to turn it into a decimal.
A way of representing decimals is [tex]\frac{x}{100}[/tex], like [tex]\frac{69}{100}=0.69[/tex].
Therefore, we can convert [tex]\frac{8}{25}[/tex] into hundredths and find the decimal that way.
[tex]\frac{8}{25} = \frac{x}{100}[/tex]
We can cross multiply to find the value of x.
[tex]100\cdot8=800\\\\800\div25=32[/tex]
This means that [tex]\frac{8}{25} = \frac{32}{100}[/tex]. This means the decimal is 0.32.
Adding the 5 to it, we get 5.32.
Hope this helped!
Given that f(x)= 4x-3 and g(x)= 2x-1 over 3 solve for g(f(2))
Answer:
[tex]g(f(2))=3[/tex]
Step-by-step explanation:
So we have:
[tex]f(x)=4x-3\text{ and } g(x)=\frac{2x-1}{3}[/tex]
And we want to solve for g(f(2)).
First, find f(2):
[tex]f(2)=4(2)-3[/tex]
Multiply:
[tex]f(2)=8-3[/tex]
Subtract:
[tex]f(2)=5[/tex]
Now, substitute this in for g(f(2)):
[tex]g(f(2))=g(5)[/tex]
Substitute this in for g(x):
[tex]g(5)=\frac{2(5)-1}{3}[/tex]
Multiply:
[tex]g(5)=\frac{10-1}{3}[/tex]
Subtract:
[tex]g(5)=\frac{9}{3}[/tex]
Divide:
[tex]g(5)=3[/tex]
Therefore:
[tex]g(f(2))=3[/tex]
A line segment has endpoints at (–4, –6) and (–6, 4). Which reflection will produce an image with endpoints at (4, –6) and (6, 4)? a reflection of the line segment across the x-axis a reflection of the line segment across the y-axis a reflection of the line segment across the line y = x a reflection of the line segment across the line y = –x
Answer:
reflection in the y- axis
Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y )
Note the x- coordinate is opposite in sign and the y- coordinate remains unchanged.
Thus
(- 4, - 6 ) → (4, - 6 )
(- 6, 4 ) → (6, 4 )
The endpoints have been reflected in the y- axis
We want to see which reflection we need to use to transform the given segment into the desired one.
The correct answer is:
"a reflection of the line segment across the y-axis"
First, we want to change the segment with endpoints at (-4, -6) and (-6, 4) to a segment with endpoints (4, -6) and (6, 4).
Note that the only thing that changes is the x-value of the endpoints, so we need to apply a reflection that only changes the x-value.
That reflection is a reflection across the y-axis.
For a general point (x, y), a reflection across the y-axis transforms the point to (-x, y).
Then the correct option is:
"a reflection of the line segment across the y-axis"

A surveyor is surveying a street. The surveyor is standing at point C looking down the street at no parking sign at point D and a stop sign at point R. Given CD = 6x-8 meters, DR = 4 meters, and point D is between C and R, what is x in meters?
Answer:
2Step-by-step explanation:
If point D is between C and R, then the vector CD = DR is true. Given the following parameter CD = 6x-8 meters, DR = 4 meters, to get the value of X we will equate both vector functions as shown;
6x-8 = 4
add 8 to both sides
6x-8+8 = 4+8
6x = 12
divide both sides by 6
6x/6 = 12/6
x = 2
Hence the value of x in metres is 2 metres.
