If the diagonal of a square is 12√2 cm . Find its area

Answers

Answer 1

Answer:

A = 144 cm²

Step-by-step explanation:

Let the side of the square be x. Using Pythagoras theorem for square,

[tex]x^2+x^2=(12\sqrt2)^2\\\\2x^2=288\\\\x=12\ cm[/tex]

The area of the square is given by :

A = side²

Put values in the formula.

A = 12²

A = 144 cm²

So, the area of the square is equal 144 cm².

At 11:45 A.M. Jason glanced at the clock. His doctor's appointment was in 2 ½ hours. At what time was his appointment

Answers

Answer:

14 : 15 or 2 : 15 pm

Step-by-step explanation:

Time of the appointment = 11: 45 +  2 ½ hours

Jason's appointment is in  2 ½ hours. His appointment is in 2 hours + 1/2 of an hour

1/2 of an hour = 1/2 x 60 = 30 minutes

Remember that 60 minutes make one hour

Time of the appointment = 11:45 + 2:30

 [tex]11 : 45[/tex]

+ 2 : 30

 13 :  75

we would have to adjust the time derived from the addition because the maximum minutes that exist is 60

To adjust, remove 60 minutes from the minutes and add it to the hour

this gives 14 : 15 or 2 : 15 pm

Answer:

The slope of the line is -19. A line that will pass through that will be y=-19x+66. THE ANSWER YOU ARE LOOKING FOR IS THAT THE SLOPE IS -19

Step-by-step explanation:

m = (y2 - y1)/(x2 - x1)    [Formula to find slope from two points]

m=(9-(-10))/(3-4)           [Plugging the two points in]

Answers

You see how y=4x and the left side on the table is x and the right side is y you plug whatever number is on the x side into the -4x
For example let’s do the first one y=-4(9) -4 multiplied by 9 is 36 so y=36 so you put 36 in the first box on the right (y side)

Answer:

1) (-36)

2) 4

3) (-4)

4) (-20)

5) (-12)

Step-by-step explanation:

See, above it written that y = (-4)x

Then below they are giving the value of x

So, according to that we have to solve the value y

For example:

y = (-4) x 9

y = (-36)

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Answers

Answer:

8 38/45 inches

Step-by-step explanation:

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Let us represent:

Length of regular size chocolate bar = x

Length of king size chocolate bar = y

A regular size chocolate bar is 5 and 4/9 inches long.

x = 5 4/9 inches

If the king size bar is 3 and 2/5 inches longer,

Hence:

y = x + 3 2/5 inches

The length of the king size bar is calculated as:

5 4/9 inches + 3 2/5 inches

(5 + 3) + ( 4/9 + 2/5)

Lowest common denominator = 45

8 + (20 + 18/45)

8 38/45 inches

The test scores of 8 students are shown in the table above. Let m be the mean of the scores and M be the median of the score. What is the value of M-m?

Answers

Answer:

0

Step-by-step explanation:

Both M and m equal 81

The resultant value of the difference of Median and Mean will be 0.

Define Mean, Median and Mode for a given set of data.

The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.

The median is the middle value when a data set is ordered from least to greatest.

The mode is the number that occurs most often in a data set.

Given is the test scores of 8 students are shown in the table.

We can write the data in the order least to greatest as -

67, 75, 75, 75, 87, 87, 91, 91

Mean = 648/8 = 81

Median = (75 + 87)/2 = 81

So, we can write (Median- Mean) as 81 - 81 = 0

Therefore, the resultant value of the difference of Median and Mean will be 0.

A is the point (-4,5) and B is the point (5,8). The perpendicular to the line AB at point A crosses the y axis at point C. Find the coordinates of C.

Answers

Answer: Point C is (0, -7)

Step-by-step explanation:

For a general line y = a*x +b

A perpendicular line to this one will have a slope equal to -(1/a)

First, for a line y = a*x + b that passes through points (x₁, y₁) and (x₂, y₂) the slope is:

a = (y₂ - y₁)/(x₂ - x₁)

Then for a line that passes through the points A (-4, 5) and B (5, 8) the slope is:

a = (8 - 5)/(5  - (-4))  = 3/9 = 1/3

a = 1/3

Then, a line perpendicular to this one will have the slope:

a' = -(1/(1/3) = -3

Then the perpendicular line is something like:

y = -3*x + b

Now we know that this line passes through point A, then when x = -4, we have y = 5

if we replace these values we get:

5 = -3*(-4) + b

5 = 12 + b

5 - 12  = b

-7 = b

Then our line is:

y = -3*x - 7

This line intersects the y-axis at point C, we know that the y-axis corresponds to x = 0.

Then:

y = -3*0 - 7

y = -7

The point C is (0, -7)
