Which statement about the stamps is correct?

Elina [12.6K]

Answer: C.) The total number of stamps is 35.

Step-by-step explanation:

Given the table :

No of 45-cent stamp - - - No of 65-cent stamp

- - - - - - - 18 - - - - - - - - - - - - - - 17

- - - - - - - 20 - - - - - - - - - - - - - - - 15

- - - - - - 22 - - - - - - - - - - - - - - 13

- - - - - - 10 - - - - - - - - - - - - - - - - 25

Verifying each option stated :

Total value of stamp:

Each row add up to 35. Example (18 + 17) = 35

(20 + 15) = 35

(22 + 13) =35

(10 + 25) = 35

Total value of stamp:

Using the first row:

45 cent = $0.45 ; 65 cent = $0.65

(10 * 0.45) + (25 * 0.65)

= $4.5 + $16.25 = $20.75

Not all rows add up to $19.15

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed

lions [1.4K]

Answer:

4424 books

Step-by-step explanation:

After the revenue from each book pays for its own cost, it can contribute to the payment of the fixed costs. That "contribution margin" is ...

$25.50 -11.25 = $14.25

If each book sold contributes that much to the recovery of fixed costs, then the total number of books that must be sold to break even is ...

$63,042/($14.25/book) = 4424 books

4424 books must be produced and sold so production costs equal sales.

Which classification describes AMNO with vertices M(2, -3), N(3, 1), and<br> 0(-3, 1)?

Sonja [21]

Answer:

Option D

Step-by-step explanation:

32). Given vertices of the triangle are M(2, -3), N(3, 1) and O(-3. 1).

Distance between two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by the expression,

Distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between M(2, -3) and N(3, 1) will be,

MN = $\sqrt{(3-2)^2+(1+3)^2}$

= $\sqrt{1+16}$

= $\sqrt{17}$

Distance between M(2, -3) and O(-3, 1),

MO = $\sqrt{(2+3)^2+(-3-1)^2}$

= $\sqrt{25+16}$

= $\sqrt{41}$

Distance between N(3, 1) and O(-3, 1),

NO = $\sqrt{(3+3)^2+(1-1)^2}$

= 6

Condition for right triangle,

c² = a² + b² [Here c is the longest side of the triangle]

By this property,

MO² = MN² + NO²

$(\sqrt{41})^2=(\sqrt{17})^2+6^2$

41 = 17 + 36

41 = 51

False.

Therefore, given triangle is not a right triangle.

Since, length of all sides are not equal, given triangle will be a scalene triangle.

Option D is the correct option.
