what is the value of x if length is 3x-1 and width is x and the perimeter is 84
Answers
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.

from here we can think of this as 3(2x-1) all over 5 = 1(5x-3) all over 4,
now we can start by expanding the left side, so it will equal 6x-3 all over 5 = 5x-3 all over 4
Now multiplying both sides by 5 to get rid of the divided by 5 on the left hand....
6x-3 = 25x-15 all over 4
We then multiply both sides by 4 to eliminate the divided by 4 on the right hand side....
We get 24x-12=25x-15
Now subtract 25x from both sides....
-1x = -3
Therefore diving both sides by -1 we get x=3
Turn 5 8/25Into a decimal
Answers
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))
Answers
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 shopkeeper earns a profit of 250₹ on every chair and a loss of 175₹ on every table he sells. Find his profit or loss if he sells 12 chairs and 9 tables on a particular day.
Answers
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
how to do this question plz answer me step by step plzz
Answers
Answer:
No
Step-by-step explanation:
Diameter= 180cm
Circumference of each table
= πD
= 180π cm
Each table can fit
= 180π ÷70
= 8 guests (nearest whole number)
Since there are 18 tables, total number of guests
= 8(18)
= 144 guests
Since there are only enough tables to sit 144 guests, there are not enough tables to fit 145 guests.
Note that we cannot take the sum of the circumference for 18 tables than divide by 70 to see how many guests can fit because a guest can only be sitted on one table.
If that was done,
Total circumference
= 180π(18)
= 10179 cm (5 s.f.)
Total number of people
= 10179 ÷70
= 145 people (3 s.f.)

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?
Answers
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?

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
Answers
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?
Answers
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.

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.
