A rectangular prism has a length of 11.8 meters, a width of 4 meters, and a height of 5 meters. What is the volume of the prism?

Answers

Answer:

the volume of the prism is 236 m^3

Step-by-step explanation:

The computation of the volume of the prism is shown below:

As we know that

The Volume of the prism is

= length × width × height

= 11.8 × 4 × 5

= 236 m^3

hence, the volume of the prism is 236 m^3

Find the distance between the points.
​(​-2,4​) and ​(-2​,8​)

Answers

Answer:

4 units

Step-by-step explanation:

Given points:

  • (-2, 4)
  • (-2, 8)

As the x-coordinates of both points are the same, the two points line on the vertical line x = -2.

Therefore, to find the distance between the points, find the absolute value of the difference between their y-coordinates:

\textsf{Distance}=|4-8|=|-4|=4

Therefore, the distance between points (-2, 4) and (-2, 8) is 4 units.

Answer:

+4

Step-by-step explanation: 4y and 8y would be 4 away from each other in the positive direction starting from 4y to get to 8y, therefore the diatance between (-2,4) and (-2,8) is 4

David wants to hang a mirror in his room. The mirror and frame must have an area of 8 square feet. The mirror is 2 feet wide and 3 feet long. Which quadratic equation can be used to determine the thickness of the frame, x?2x2 + 14x − 2 = 0
3x2 + 10x − 8 = 0
4x2 + 10x − 2 = 0
x2 + 7x − 8 = 0

Answers

Represent the thickness of the frame by x. Framing the mirror will increase both its length and width by 2x. The area of the mirror with the frame is the product of the length and width which can mathematically be expressed as,                                 

                                               A = (3 + 2x)(2 +2x) = 8

The equation above can be simplified into 4x^2 + 10x -2 = 0. This equation can still be further simplified by dividing it by 2. However, it will give an answer which is not found on the choices. Thus, the answer is the third choice.

Your personal library contains books written by 165 authors. 60% of the authors are men. 40% of the authors write only nonfiction works. Also, 40 of the male authors write only nonfiction works. Assuming that your library has only one book by each author, what is the probability that a book picked at random is either a work written by an author who writes only nonfiction or a work written by a man?

Answers

The chances of finding either a work authored by a woman or a work written by a man in a book chosen at random are 25/33.

What is the probability?

Probability is synonymous with possibility. It is concerned with the occurrence of a random event. Probability can only have a value between 0 and 1.

The probability that a book picked at random is either a work written by an author who writes only nonfiction or a work written by a man is found as;

\rm P = (40 \  \% \  of  \ 165 + 60 \%  \ of  \ 165 -40  )/(165) \n\n\ P= (25)/(33)

Hence the chances of finding either a work authored by a woman or a work written by a man in a book chosen at random are 25/33.
