A Liberian sorts 350 books at a constant role. After a days, the librarian still has 150 books to son, How much time does it take to sort the books from start to
finish
Answer: 7 days
Step-by-step explanation:
Books already sorted;
= 350 - 150
= 200
Time taken = 4 days
Rate = 200/4
= 50 books a day
150 books remain;
= 150/50
= 3 days
Total time = 4 + 3
= 7 days
Using Pythagoras' theorem, calculate the length of the hypotenuse in this right-
angled triangle.
Give your answer in centimetres (cm) to 1 d.p.
6 cm
2.5 cm
Answer:
6.5
Step-by-step explanation:
Look at image.
Hope it helps
The length of the hypotenuse in the right-angle triangle of length and base is 6.5 cm.
From the Pythagoras theorem, the sum of squares of the two sides of a right-angle triangle is equal to the square of the hypotenuse.
We can calculate the third side using Pythagoras' theorem, as the base and perpendicular sides are given.
Given:
Sides, x = 6 cm and y = 2.5 cm
From Pythagoras' theorem:
x² + y² = z²
6² + 2.5² = 6.5 cm
Hence, the length of the hypotenuse in the right-angle triangle is 6.5 cm.

Determine whether the ordered pair is a solution of the linear inequality.
x ≤ 3; (–2, 6)
Answer:
[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
Thus, -2 comes under the interval domain of the inequality (-∞, 3].
Hence, (-2, 6) is a solution to the linear inequality.
Step-by-step explanation:
Given the linear inequality
x ≤ 3
substitute the value of x = -2
-2 ≤ 3
TRUE
It is clear that -2 is indeed less than 3. Thus, the ordered pair (-2, 6) is a solution to the linear inequality.
Also,
[tex]x\le \:3\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:3\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:3]\end{bmatrix}[/tex]
Thus, -2 comes under the interval domain of the inequality (-∞, 3].

Let logp/n=5 and logm/n=9
Answer:
we know that
log (P/N) = log P - log N
so
log P - log N = 5----------------> equation 1
log (M/N) = log M - log N
so
log M - log N = 9 ------------------> equation 2
If you subtract equation 2 from equation 1,
you have
log M - log P = 4
That means that log (M/P) = 4 ----> 10^4 = M/P ---> M = 10000P
the answer is
the relationship between P and M is
M = 10000P

The length of RS is such that △RST∼△R′S′T′ will be 6 feet.
What is the similarity?Similar figures are those figures which are identical in shape, but not necessarily in size.
Two squares with sides of 10 and 5 are similar because their shape is exact but the size is different.
Given two triangles are similar △RST∼△R′S′T′
If two triangles are similar then the ratio of the corresponding side must be the same.
Therefore,
RS/R'S' = TS/T'S'
(12x + 2)/(5x + 1) = 9/4
By cross multiplication,

Step-by-step explanation:
Someone can help me with this?
Answer:
D) 121 degrees
Step-by-step explanation:
A linear pair is a pair of angles that share a side and a base. In other words, they are the two angles created along one line when two lines intersect. Linear pairs are always supplementary.
In this case, since supplementary angles add up to 180 degrees, we set up an equation:
<A+<B=180
(6x-19)+(11x-22)=180
17x-41=180
17x=221
x=13
Now we plug in x=13 for angle B:
11x-22
11(13)-22
143-22
121
Therefore, the measure of angle B is 121 degrees
Write a function called height_range that accepts a list of integers representing heights in inches as an argument and returns the the difference between the tallest height and the shortest height. Assume that all heights are positive values.
The following function height_range in python language will accept a list of integers and return the difference between the tallest and shortest height.
What is a python programming language?Python is a well-liked computer programming language used to build websites and software, automate procedures, and conduct data analysis. Since Python is a general-purpose language, it may be used to create a wide range of applications and isn't specifically designed to address any particular problems. Because of its high-level built-in data structures, dynamic typing, and dynamic binding, it is appropriate for Rapid Application Development as well as for use as a scripting or glue language to connect existing components.

Answer:
D. sqrt 13
Step-by-step explanation:
took on edge :)
The required magnitude of the vector is √13. Option D is correct.
A graph is given, that shows the vector, the magnitude of the vector is to be determined.
Vector form is defined as representing any point in space that has both magnitude and direction. A point k in space is represented as a vector OKi + OKj, which denotes the vector line, OK joining the line from the origin O to the point k. The vector form is used to define a line or a plane in a 3D space.
From the figure,
given vector can be expressed as,
[tex]\bar v = 3\bar i+2\bar j[/tex]
now the magnitude of vactor,
[tex]|\bar v| = \sqrt{3^2+2^2}\\|\bar v| = \sqrt{9+4}\ \\|\bar v| = \sqrt{13}\[/tex]
Thus, the required magnitude of the vector is √13. Option D is correct.
