Answer:

c. Zhen spends 6 1/2 hours working per audiobook.

Step-by-step explanation:

The table below gives some completed audio lengths and the amount of time Zhen spends on the audiobook.

[tex]\left|\begin{array}{c|c}$Completed length of audiobook (hours) &$Working time (hours)\\---------&--------\\1&6\frac{1}{2} \\\\3\frac{1}{2}&22\frac{3}{4}\\\\7&45\frac{1}{2}\\\\10&65\end{array}\right|[/tex]

We observe that from the table, in 6.5 hours, Zhen completes 1 audiobook.

In fact, across the table:

[tex]\dfrac{6\frac{1}{2}}{1}=\dfrac{22\frac{3}{4}}{3\frac{1}{2}}=\dfrac{65}{10}=6\dfrac{1}{2} $ hour per audiobook[/tex]

Therefore, in this situation, 6.5 hours mean that Zhen spends 6.5 hours working per audiobook.

The correct option is C.

Answer:

Air pressure = [tex]4.6\frac{\text{lb}}{\text{in}^{2} }[/tex]

Step-by-step explanation:

Relationship between air pressure and altitude can be modeled by,

P = 14.7e[tex]14.7e^{-0.00004h}[/tex]

Where P = Air pressure

and h = altitude above the sea level

Air pressure on Mount Everest having altitude = 29028 feet abve the sea level will be,

P = [tex]14.7e^{-0.00004\times 29028}[/tex]

  = [tex]14.7\times e^{-1.16112}[/tex]

  = 4.603

  ≈ 4.6 [tex]\frac{\text{lb}}{\text{in}^{2} }[/tex]

Therefore, air pressure on Mount Everest = 4.6 [tex]\frac{\text{lb}}{\text{in}^{2} }[/tex]

Answer:

the real answer is (8,-4)

Step-by-step explanation:

If the midpoint of the AB is (5.5, 0) then the coordinate of the B will be given as (8, -4).

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Point A is at (3, 4) and point M is at (5.5,0).

Point M is the midpoint of points A and B.

Then the point of B is given as

[tex]\rm (x_1,y_1) = (2x-x_2, 2y-y_2)\\\\(x_1,y_1) = (2\times 5.5 - 3, 2\times 0-4)\\\\(x_1,y_1) = (8, -4)[/tex]

Answer:

Cans for food drive

Step-by-step explanation:

Answer:

Cans for food drive

Step-by-step explanation:

The header should encapsulate all aspects of the table.

Cans of food are brought by the teachers to be donated to the food drive. Hence the answer should be cans for food drive.

Cans recycled are out of context as the cans of food are for donation as seen in the table, not for recycling.

Favourite food and favourite teacher cannot be measured by the data provided which is which teacher bringing how many cans of food for donation. Hence, these 2 are not the answer as well.

Answer:

  295 months

Step-by-step explanation:

You want to know the number of months required to pay off a 30-year loan of $125000 at 6% if an extra payment is made each year.

The number of payments required will depend on the actual payment schedule, and the way the lender computes interest due.

The attached calculation shows it takes 319 payments. The assumption is that they are evenly spaced at 13 payments per year (one every 4 weeks), and the interest is computed on the interval between payments.

If 13 payments are made per year, the number of years it takes to pay off the loan will be ...

  319/13 = 24 7/13

24 years and 7 months is 295 months.

__

Additional comment

If the first payment is made on Jan 28, and payments are made every 4 weeks, there will be 2 payments in Dec. That is, except for the last month of the year, there will be 1 payment per month.

If regular monthly payments are made, but one of the payments is doubled, the result may be different.

Answer:

Denote the two numbers: a and b

Two numbers are in the ratio 7:5

=> a/b = 7/5

=> a = (7/5) x b     (1)

When 10 is subtracted from each term , the ratio becomes 3:2

=> (a - 10)/(b - 10) = 3/2

=> 2 x (a - 10) = 3 x ( b - 10)

=> 3 x b - 2 x a = 10

From (1) => 3 x b - 2 x (7/5) x b = 10

             => (1/5) x b = 10

             => b = 50

             => a = (7/5) x b = (7/5) x 50 = 70

Answer:

Step-by-step explanation:

The matrix AB is:

[tex]AB=\left[\begin{array}{ccc}50&44&-43\\31&16&7\\37&119&-94\end{array}\right][/tex]

-----------------------------------

This question is solved using multiplication of matrices.

To do this, we multiply the lines of the first matrix by the columns of the second.

-----------------------------------

In this question:

The first matrix is:

[tex]A =\left[\begin{array}{ccc}5&7&2\\4&-1&3\\6&8&-5\end{array}\right][/tex]

The second matrix is:

[tex]B = \left[\begin{array}{ccc}6&11&-4\\2&1&-5\\3&-9&6\end{array}\right][/tex]

------------------------------------

First line:

------------------------------------

Second line:

Second line of A by each column of B, so:

[tex]A_{2,1} = 4\times6 - 1\times 2 + 3\times3 = 31[/tex]

[tex]A_{2,2} = 4\times11 - 1\times 1 + 3\times (-9) = 16[/tex]

[tex]A_{2,3} = 4\times(-4) - 1\times (-5) + 3\times 6 = 7[/tex]

------------------------------------

Third line:

Third line of A by each column of B, so:

[tex]A_{3,1} = 6\times6 + 8\times 2 - 5\times3 = 37[/tex]

[tex]A_{3,2} = 6\times11 + 8\times 1 - 5\times (-9) = 119[/tex]

[tex]A_{3,3} = 6\times(-4) + 8\times (-5) - 5\times 6 = -94[/tex]

------------------------------------

Thus, the matrix is:

[tex]AB=\left[\begin{array}{ccc}50&44&-43\\31&16&7\\37&119&-94\end{array}\right][/tex]

Answer:

In a right triangle, as the angle increases, the value of the sine increases.

Step-by-step explanation:

Think of the unit circle, a circle with radius 1 unit centered at the origin which is the point with coordinates (0, 0). Draw a radius of the circle from the center, to point (1, 0) on the positive x-axis. The angle formed by this radius and the positive x-axis is 0 degrees. This is an angle in standard position. The endpoint of the radius on the circle has a y-coordinate. The y-coordinate is the sine of the angle. As you choose points on the circle going up from the positive x-axis, the angle formed by the radius connected to the point on the circle and the positive x-axis increases in measure until it coincides with the positive y-axis, where it has a measure of 90 degrees. The sine of the angle is always the y-coordinate of the point on the circle. As the angle increases from 0 to 90 degrees, the y-coordinate increases from 0 to 1. The acute angles of a right triangle can have measures of only between 0 and 90 degrees.

Answer: In a right triangle, as the angle increases, the value of the sine increases.
