In a school library, 40% of the books are in Nepali language, 40% of the remaining books are in English and the remaining books are in regional languages. If the number of books in English language is 4800, find the total number of books in the library,
Step-by-step explanation:
Solution,
Let the total number of books be x, then
Books in English language=4800
40% of x=4800
40/100×x=4800
40x/100=4800
40x=4800×100
40x=480000
x=480000/40
x=12000
So the total number of books in the library is 12000.

Find the length of "c" to the
nearest tenth using the
Pythagorean Theorem.
Enter
Answer:
10.6
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Where a and b = the legs and c = hypotenuse
We are given two legs and need to find the hypotenuse
Given:
Short leg (a) = 7
Long leg (b) = 8
Hypotenuse = c
Now to find the value of c we simply plug in the values of the variables into the Pythagorean theorem and solve for c
Pythagorean theorem: a² + b² = c²
a = 7, b = 8, c = c
Plug in values
7² + 8² = c²
Now solve for c
Simplify exponents
49 + 64 = c²
Add
113 = c²
Taking the square root of both sides
c = 10.6 ( rounded to the nearest tenth )
Answer:
c = 10.6
Step-by-step explanation:
[tex]h {}^{2} = p {}^{2} + b {}^{2} \\ c {}^{2} = (8) {}^{2} + (7) {}^{2} \\ c = \sqrt{64 + 49} \\ c = \sqrt{113} \\c = 10.6[/tex]
How would I simplify this expression
Answer:
-3 - 16b
Step-by-step explanation:
by simply doing the multiplication and then add combinable terms.
9 - 4(3 + 4b) = 9 - 12 - 16b = -3 - 16b
Explanation:
Let's simplify step-by-step:
9-4(3 + 4b)
Distribute:
= 9 + (-4)(3) + (-4)(4b)
= 9 + (-12) + (-16b)
Combine Like Terms:
= 9 + (-12) + (-16b)
= (-16b) +(9 + (–12) )
= -16b + (-3)

(help pls it’s my hw)
Answer:
Step-by-step explanation:
A rectangle has the perimeter of 66cm, and since a rectangle has 2 lengths and 2 widths, we can tell that 2 widths = 66-27*2 = 12

Write the equation of the circle centered at (4, - 9) with diameter 16.
HELP A GIRL OUT
Answer:
16= (x-4)^2 +(y+9)^2
Step-by-step explanation:
hey! The formula for the equation of a circle is r^2= (x-h)^2 + (y-k)^2
r= the radius (in your case you have the diameter so you do not need to square it)
(h,k)= is the center coordinates, so your center coordinate would be (4, -9). You now have your h (h=4) and your k (k=-9) so you can plug it in the formula! :)

what must be added to 2x^2 - 5x - 12 in order to get 7x^2 - x - 18
Answer:
5x^2 +4x -6
Step-by-step explanation:
that is the answer
yep
Answer:
5x² + 4x - 6
Step-by-step explanation:
Subtract 2x² - 5x - 12 from 7x² - x - 18 , that is the opposite operation, that is
7x² - x - 18 - (2x² - 5x - 12) ← distribute parenthesis by - 1
= 7x² - x - 18 - 2x² + 5x + 12 ← collect like terms
= 5x² + 4x - 6
5. Use your answers to questions 3 and 4 to write an expression for how many times greater organism B's population is than organism A's population after 8 days. Simplify your expression, then write it as a number that is not in exponential form. Show your process. Write your answer in the space below. My answer
Population growth represents the rate at which the population changes
The expression for the number of times the population of B is greater than A is: [tex]2^6[/tex]The expression that is not in exponential form is: 64Given that:
[tex]r_1 = 2[/tex] ----- i.e. when the population doubles
[tex]r_2 = \frac{1}{2}[/tex] ----- i.e. when the population cut in halves
Population growth is represented as: [tex]A_n = ar^{n}[/tex]
Organism A
For the first 5 days (when it doubles) is:
[tex]A_5 = ar_1^{5[/tex]
Substitute [tex]r_1 = 2[/tex]
[tex]A_5 = a\times 2^{5[/tex]
For the next 3 days (when it cut in halves) is:
[tex]A = A_5 \times r_2^3[/tex]
Substitute [tex]A_5 = a\times 2^{5[/tex] and [tex]r_2 = \frac{1}{2}[/tex]
[tex]A= a \times 2^5 \times (\frac{1}{2})^3[/tex]
Apply law of indices
[tex]A = a \times 2^5 \times 2^{-3[/tex]
[tex]A = a \times 2^{5-3[/tex]
[tex]A = a \times 2^{2[/tex]
So, the growth factor of organism A is:
[tex]A = a \times 2^{2[/tex]
Organism B
For the 8 days, we have:
[tex]B=ar_1^8[/tex]
[tex]B=a\times 2^8[/tex]
The expression (n) for the number of times the population of B is greater than A is:
[tex]n = \frac BA[/tex]
This gives:
[tex]n = \frac{a \times 2^8}{a \times 2^2}[/tex]
[tex]n = \frac{2^8}{2^2}[/tex]
Apply law of indices
[tex]n = 2^{8-2}[/tex]
[tex]n = 2^{6}[/tex]
The expression that is not in exponential form is:
[tex]n = 2 \times 2\times 2\times 2 \times 2\times 2[/tex]
[tex]n = 64[/tex]
Hence:
The expression for the number of times the population of B is greater than A is: [tex]2^6[/tex]The expression that is not in exponential form is: 64Read more about population growth at:

Avery has three times as much money as Jackie. Jackie has $6 less than Samantha. Together they have $56. How much money does each have?
HEEEEELP
The money belongs to Jackie, Avery, and Samantha is $10, $30, and $16 respectively.
Given that,
Avery has three times as Jackie.
Also, Jackie has $6 lower than Samantha.
Together they have $56.
Based on the above information
Let us assume the Jackie be x
So, Avery should be 3x
Samantha should be x + 6
So, the equation should be
x + 3x + x + 6 = $56
5x = $56 - $6
5x = $50
x = $10
So, Jackie has $10
Avery has $30
And, Samantha has $16
Therefore we can conclude that the money belongs to Jackie, Avery, and Samantha is $10, $30, and $16 respectively.
