Answer: The phrase is "The time it takes to read a book depends on the number of pages in the book"
so the time is the dependent variable and the pages are the independent variable.
Then you will have a function of the form Time(pages) in which you introduce a number of pages (the total number of pages in a book, in this case) and returns the time it takes to read them all. So the correct answer is A.

Question 5.
(3a,b)
4a
area is 4ab
2a
Answer:
#4) 1/2(ab); #5) 3a, 4a, 4ab, 2a
Step-by-step explanation:
#4) Take the top triangle. The height will be the difference in the y-coordinates of J and M:
b-0 = b
The base of the triangle would be the difference in the x-coordinates of J and K:
a-0 = a
The area is given by the formula A=1/2bh, where b is the base and h is the height; substituting our height and base, we have
A=1/2(b)(a) = 1/2(ab)
#5) To find the midpoint of a section, we add together the x-coordinates and divide by to, and add together the y-coordinates and divide by 2.
The endpoints of FE are (4a, 0) and (2a, 2b). This makes R:
[tex](\frac{2a+4a}{2},\frac{2b+0}{2})\\\\=(\frac{6a}{2},\frac{2b}{2})\\\\=(3a, b)[/tex]
The length of DF can be found by subtracting the x-coordinates:
4a-0 = 4a
The area is then found by multiplying 1/2 by the base and the height:
A=1/2(4a)(2b) = 1/2(8ab) = 4ab
The length of QR can be found by subtracting the x-coordinates:
3a-a = 2a
Hiram sells kites to various corporations. To maintain his business, he must sell an average of 50 kites per month. After 5 months, Hiram has sold 30, 42, 77, 90, and 52 kites in each of the 5 months. How many kites would Hiram have to sell in the 6th month for him to meet his average of 50 kites?
Answers
=> sum of values = average * number of values
average = 50
number of values = number of months = 6
=> sum of values = 50 * 6 = 300
sum of values = 30 + 42 + 77 + 90 + 52 + x = 300
Where x is the number of kites that he has to sell to meet 300 kites sold.
x = 300 - 30 - 42 - 77 - 90 - 52 = 9
Answer: he has to sell 9 kites to meet the average of 50 kites monthly.

What is the value of x?
a. 68°
b. 62°
c. 112°
d. 124°
Answers
On a isosceles triangle, the base angles are the same.
We add them together 56° + 56° = 112°
To know X, we subtract 112° from the total
180° - 112° = 68°
X = 68°
OR as an equation
56 + 56 + x = 180
112 + x = 180
x = 180 - 112
x = 68
Which trigonometric function would be used to find the length of this triangle's hypotenuse?
Answers

use pythagorean thm to doubke check answer
The cosine function is used to find the length of the hypotenuse of a triangle by utilizing the Pythagorean theorem.
The trigonometric function used to find the length of the hypotenuse of a triangle is the cosine function. In a right triangle, the cosine function is defined as the ratio between the length of the adjacent side to the length of the hypotenuse.
To find the length of the hypotenuse, you can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the hypotenuse.
For example, if the lengths of the shorter sides are 9 blocks and 5 blocks, then the length of the hypotenuse would be √(9² + 5²) = √(81 + 25) = √106 = 10.3 blocks.

Step-by-step explanation: We are given to solve the following system of equations :

From equation (ii), we have
[tex]2x-y=2\\\\\Rightarrow y=2x-2~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(iii)[/tex]
Substituting the value of y from equation (iii) in equation (i), we get
[tex]x+3(2x-2)=22\\\\\Rightarrow x+6x-6=22\\\\\Rightarrow 7x=22+6\\\\\Rightarrow 7x=28\\\\\Rightarrow x=\dfrac{28}{7}\\\\\Rightarrow x=4.[/tex]
From equation (i), we get
[tex]4+3y=22\\\\\Rightarrow 3y=22-4\\\\\Rightarrow 3y=18\\\\\Rightarrowy=\dfrac{18}{3}\\\\\Rightarrow y=6.[/tex]
Thus, the required solution is (x, y) = (4, 6).

Which of the following statements is true?
All trapezoids are parallelograms.
All parallelograms are trapezoids.
All rectangles are squares.
All rhombuses are rectangles.
Answers
Answer:
The answer is B. All parallelograms are trapezoids.
Step-by-step explanation:
The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. That makes the opposite of facing sides are parallel to each other. The the definition of trapezoid is a convex quadrilateral with at least one pair of parallel sides. Therefore, all parallelograms are trapezoids.
The true statement among the given options is, B. All parallelograms are trapezoids.
A trapezoid is a quadrilateral with at least one pair of parallel sides, but it doesn't require all sides to be parallel. Therefore, not all trapezoids are parallelograms. (Statement A is false)
A parallelogram is a quadrilateral with both pairs of opposite sides parallel. Every trapezoid has at least one pair of parallel sides, so it can be considered a special case of a parallelogram. Therefore, all trapezoids are parallelograms. (Statement B is true)
A rectangle is a quadrilateral with all four angles equal to 90 degrees. It has opposite sides that are parallel and equal in length. A square is a special type of rectangle with all sides of equal length. However, not all rectangles have all sides of equal length, so statement C is false.
A rhombus is a quadrilateral with all four sides of equal length. It has opposite sides that are parallel, making it a parallelogram. Since a rectangle is a parallelogram with right angles, and a rhombus is a parallelogram with equal sides. Therefore, statement D is also false.

A solid right pyramid has a regular hexagonal base with an area of 7.4 units2. The pyramid has a height of 6 units.
What is the volume of the pyramid?
11.1 units3
14.8 units3
22.2 units3
44.4 units3
Answers
Answer:
Option B. 14.8 units³ is the answer.
Step-by-step explanation:
It is given in the question A solid right pyramid which has a regular hexagonal base with area = 7.4 unit²
Height of the pyramid = 6 units.
We have to calculate the volume of the pyramid.
Since volume of the pyramid = (1/3)×Area of the base × height
Volume = (1/3)×7.4×6 = 7.4 × 2 = 14.8 units³
Therefore option B. 14.8 units³ is the answer.
It should be noted that the volume of the pyramid will be 14.8 unit³.
How to calculate the volume of the pyramidFrom the information given, the solid right pyramid has a regular hexagonal base with an area of 7.4 units².
The height of the pyramid is also 6 units. Therefore, the volume of the pyramid will be:
= 1/3 × Area of the base × height
= 1/3 × 7.4 × 6
= 14.8 units³
In conclusion, the volume of the pyramid is 14.8 unit³.

How many length 6 passwords with 1 number 1 upper and 1 lower?

- No passwords without numbers allowed, so we subtract 52⁶
- No passwords without uppercase allowed, so we subtract 36⁶

Now we have subtracted the passwords of all capitals twice, so we have to add those back in: add 26⁶
Same for all lowercase and all numbers: add 26⁶ and 10⁶

an artist is cutting pieces of ribbon to use in a project. Each piece he cuts measures 7/8 inch. The aritst cuts off 5 pieces. How many total inches of ribbon has he cut off?
Answers
The artist has cut off a total of 4 and 3/8 inches of ribbon for his project by multiplying the length of one piece (7/8 inch) by the total number of pieces cut (5).
Explanation:The question involves a straightforward arithmetic operation of multiplication. Each piece of ribbon the artist cuts measures 7/8 inch, and he cuts off 5 pieces in total. To find the total length of ribbon cut off, we multiply the length of one piece (7/8 inch) by the number of pieces cut (5).
Calculation: \(\frac{7}{8} \text{ inch} \times 5 = \frac{35}{8} \text{ inches} = 4 \frac{3}{8} \text{ inches}\)
Therefore, the artist has cut off a total of 4 and 3/8 inches of ribbon for his project. This example demonstrates a practical application of multiplication in a real-world context, specifically within arts and crafts projects.

hope this helps
The solution to the equation is v = 0.
We have,
To solve the equation 7(2 + 5v) = 3v + 14, we can simplify and isolate the variable v.
Expanding the left side of the equation:
7(2 + 5v) = 14 + 35v
Now we have:
14 + 35v = 3v + 14
Next, we can combine like terms:
35v - 3v = 14 - 14
32v = 0
To solve for v, we divide both sides of the equation by 32:
v = 0/32
v = 0
Therefore,
The solution to the equation is v = 0.
