Mark's father was putting in a new kitchen floor. The dimensions were 8 feet by 12 feet. If each tile was 1 square foot, how many tiles did he need?

Answers

Answer:

96 tiles

Step-by-step explanation:

The kitchen floor is rectangular on shape.

The dimensions of the kitchen floor were 8 feet by 12 feet.

Hence, Area of a rectangle = Length × Width

Length = 8ft

Width = 12ft

Hence:

Area = 8ft × 12ft

= 96 ft²

If each tile was 1 square foot, the number of tiles he would need is

1 ft² = 1 tile

96 ft² = x

Cross Multiply

1ft² × x = 96 ft² × 1 tile

x = 96 ft² × 1 tile/1 ft²

x = 96 tiles

Therefore, Mark's father would need 96 tiles

how do you factor y=6x^2-x-2

Answers

6 x -2 = -12

-12 = 3, -4

y = 6x^2 + 3x - 4x - 2

y = 3x(2x + 1) - 2(2x + 1)

(2x + 1) (3x - 2) = 0

2x = -1, 3x = 2

x = -1/2, 2/3

pls give brainliest im trying to level up :))

Answer:

(2x+1)(3x-2)

Step-by-step explanation:

Given :-

y = 6x² - x - 2

We need to factor out the given expression. For that we may use the middle term splitting method. Taking the equation,

[tex]:\implies[/tex] y = 6x² - x - 2

[tex]:\implies[/tex] y = 6x² - 4x + 3x-2

[tex]:\implies[/tex] y = 2x ( 3x -2) +1( 3x -2)

[tex]:\implies[/tex] y = (2x + 1)(3x -2 )

Hence the required answer is y = (2x+1)(3x-2)

TIMED TEST PLEASE HELP!!!!! Explain how you got the answer as well!

Answers

Answer:

Step-by-step explanation:

Perimeter= all sides added together

so in this case

3x+1 = 2x + 2x + x-1 + x+2 + x-1 + x + 2

now you may be wondering why i put two 2x's, two 2+x, and two x-1  , the far left side is 2x and has 2 lines and so does the bottom side which has 2 lines so theyre congruent ( the same case for the 2+x and x-1 )  so you need to account for all sides.

so lets simplify this huge equation!

3x+1 = 4x + 1x - 1 + 1x + 2 + 1x - 1 + 1x + 2

3x+1 = 8x - 1 + 2 - 1 + 2

3x + 1 = 8x + 2

-3x on both sides

1 = 5x + 2

-2 on each side

-1 = 5x

x = -1/5

Drag each tile to the correct box. A data set that consists of many values can be summarized using the five-number summary. Arrange these five values in order from least to greatest.

Answers

Answer:

Minimum < Q1 < Median < Q3< Maximum

Step-by-step explanation:

Given

Minimum, Median, Maximum, Q3 and Q1

See attachment for complete question

Required

Order from least to greatest

In a dataset, the range is:

[tex]Range = Maximum - Minimum[/tex]

This implies that, the minimum is the least and the maximum is the highest of the dataset

So, we have:

Minimum <         <              <           < Maximum

The median is the middle item; So, the above becomes

Minimum <         < Median <           < Maximum

In a dataset, the IQR is:

[tex]IQR = Q_3 - Q_1[/tex]

This implies that:

[tex]Q_3 > Q_1[/tex]

So, we have:

Minimum < Q1 < Median < Q3< Maximum

The two-dot plots below show the number of miles run by 14 students at the beginning and end of the school year.

Answers

Answer:

Step-by-step explanation:

From the dot plot of start of school year,

Maximum value of the miles run = 10

Minimum value of the miles run = 5

Range of the data set = 10 - 5

                                    = 5 miles

From the dot plot of End of school year,

Maximum value of the miles run = 10

Minimum value of the miles run = 6

Range of the data set = 10 - 6

                                    = 4 miles

The range at the start of the year was 5 miles and the range at the end of the year was 4 miles.

The history of UFOs.Unidentified Flying Object (or UFO) is a term commonly used to describe lights or shapes in the sky. It was first coined by the United States Air Force in 1952 to describe sightings of mysterious objects in the sky that could not be explained even after careful investigation. Nowadays UFOs are spotted frequently, and feature in numerous movies and TV shows. Another popular name for such an object is, Flying Saucer, in reference to the round shape of many UFOs.The first widely publicized UFO sighting was in 1947, by a pilot called Kenneth Arnold. Following this event, public sightings of UFOs increased dramatically. Movies and TV shows began featuring visitors from outer space, arriving on earth in flying saucers. With the popularity of these images, many people claimed to have seen lights in the sky. Some experts believe that people simply think they see UFOs because of the influence of TV and movies.However, experts estimate that as little as 5% of these sightings could be called unidentified. Usually these lights are made by aircraft, satellites, or weather balloons. Top secret air force activities during the Cold War may have been responsible for many of the UFO sightings in America and Europe. Although not actually aliens, the secretive nature of these flying objects is definitely unidentified.Another popular idea concerning UFOs concerns the role of world governments. Specifically, people believe that the US government has discovered alien life and operates a cover-up to hide the truth from the public. The most widely believed cover-up is that of the Roswell Incident. In July, 1947, a UFO supposedly landed in Roswell, New Mexico, and was examined and hidden by government agents. There have been many investigations into the Roswell Incident, however, these reports always claim that no such event occurred.QUESTIONSComprehension(answers are at the bottom of the page)1st Reading (Skimming)Read through the article and answer each of the following questions.1.
