Answer:

   16 square units

Step-by-step explanation:

The area of a triangle is given by the formula ...

  A = 1/2bh

Here, it is convenient to choose the base as the vertical segment between y=-5 and y=3. Its length is 3 -(-5) = 8 units.

The height of the triangle is the difference in x-coordinates between that segment and the opposite vertex: 6 -2 = 4.

Then the area is ...

  A = 1/2(8)(4) = 16 . . . square units

Matrix are used to show data in rows and columns

The estimated time to efficiently solve the square matrix A is 4907.8125 seconds

The given parameters are:

Matrix size = 2000 by 2000

Time = 78125 seconds

Substitution time = 25 seconds

The time to solve the matrix is dependent on the size of the matrix, while the substitution time is fixed

The size of the similar matrix is 500 by 500

The similar matrix is 1/16 smaller than the original matrix of 2000 by 2000.

So, the time to factorize the matrix is:

[tex]Time = \frac{1}{16} * 78125\ seconds[/tex]

[tex]Time = 4882.8125\ seconds[/tex]

The estimate of the time to solve the new matrix is the sum of the time to factorize it and the substitution time.

So, we have:

[tex]Total = 4882.8125\ seconds + 25\ seconds[/tex]

This gives

[tex]Total = 4907.8125\ seconds[/tex]

Hence, the estimated time to efficiently solve the square matrix A is 4907.8125 seconds

trapezoid has four(4) sides

Answer:

[tex]x[/tex] = 2.8

Step-by-step explanation:

If the quadrilaterals are similar, then the ratios of corresponding sides will be equal:

KL : QR = 4 : 5.6 = 4 / 5.6 = 5/7

JM : PS = 7 : 9.8 = 7 / 9.8 = 5/7

LM : RS = 3 : 4.2 = 3 / 4.2 = 5/7

This shows that the ratio of KJ : QP = 5/7

KJ : QP = 2 : [tex]x[/tex] = 2 / [tex]x[/tex]

Therefore, [tex]\frac{2}{x}=\frac{5}{7}[/tex]

cross multiply:  14 = 5[tex]x[/tex]

Divide both sides by 5:  [tex]x[/tex] = 2.8

Answer:

y = 8

Step-by-step explanation:

The line that contains points (0, 8) and (8, 8) is a horizontal line in which every point has 8 as its y-coordinate.

Equation: y = 8

y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0)

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

the equation of a line that contains the points (0,8) and (8,8)

Slope=0

We need to find the y intercept

8=b

y=8 is the equation of a line that contains the points (0,8) and (8,8)

Now let us find the equation that represents a line that passes through points (-6, 4) and (2,0).

m=0-4/2+6

=-1/2

Now find the y intercept

0=2(-1/2)+b

b=1

y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0),

Hence, y=-1/2x+1 is the equation that represents a line that passes through points (-6, 4) and (2,0)

Step-by-step explanation:

each game of cribbage "binds" 4 people, each hand of chess 2 people.

15 games of cribbage means 15×4 = 60 people are playing. that leaves 0 people and therefore 0 games for chess.

2 games of chess means 2×2 = 4 people are playing.

that leaves 60-4 = 56 people for cribbage making 56/4 = 14 games of cribbage.

13 games of cribbage means 13×4 = 52 people are playing. that leaves 60-52 = 8 people for chess making 8/2 = 4 games of chess.

14 games of chess means 14×2 = 28 people are playing, that leaves 60-28 = 32 purple for cribbage making 32/4 = 8 games of cribbage.

0 people of cribbage means nobody is playing this game, that leaves all 60 people to play chess making 60/2 = 30 games of chess.

Step-by-step explanation:

First, find the unit rate. Divide 4.5 by 3 to get 1.5. 3:4.5 = 1:1.5. Then, multiply 1.5 by any number to get an equivalent ratio. For example, 1.5 times 6 = 9, so an equivalent ratio is 6:9. Or, 1.5 times 10 = 15, so another equivalent ratio is 10:15.

Answer:

34cm

Step-by-step explanation:

[tex]Solution,\\\\Area=70cm^{2} \\\\Breadth(b)=7cm\\\\Now,\\\\Length=\frac{Area}{Breadth}\\\\Length=\frac{70cm^{2} }{7cm} \\\\Length=10cm\\\\Again,\\\\Perimeter=2(l+b)\\\\Perimeter=2(10cm+7cm)\\\\Perimeter=34cm[/tex]

The required length and perimeter of the rectangle are 7 cm and 34 cm respectively.

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

Here,
Let the length of the rectangle be l,

Now,
According to the question,
Area of the rectangle, = l × w
70 = l × 7
l = 70 / 7
l = 10 cm

Now,
Perimeter of the rectangle = 2[l + w]
                                        = 2 [10 + 7]
                                        = 34 cm

Thus, the required length and perimeter of the rectangle is 7 cm and 34 cm respectively.

Step-by-step explanation:

100% = 33,000 ft

1% = 100%/100 = 33000/100 = 330 ft

6% = 1% × 6 = 330 × 6 = 1980 ft

that means the plane has to go down 1980 ft to

33,000 - 1980 = 31,020 ft

and then it goes up by 5000 ft :

31,020 + 5000 = 36,020 ft

Answer:

Step-by-step explanation:

Given,

Perimeter of a rectangular pool (P) = 40 feet

Length of the pool (l) = 12 feet

Let,

Width of the pool be = w

As we know,

Therefore,

By the problem,

=> 2(l + w) = P

=> 2(12 + w) = 40

=> 24 + 2w = 40

=> 24 - 24 + 2w = 40 - 24

=> 2w = 16

=> [tex]\frac{2w}{2}[/tex] = [tex]\frac{16}{2}[/tex]

=> w = 8

Hence,

The required width of the pool is 8 feet. (Ans)

Answer:

The Width of the pool would be 8 feet/ft. .

Step-by-step explanation:

According to the Question Given:

Perimeter = 40 ft/feet

Length of the pool = 12 ft/feet

To Find:

The width/breadth of the pool

Solution:

We know that,

[tex] \boxed{\tt \: Perimeter \: of \: Rectangle = 2(l + b)}[/tex]

So Put their values accordingly:

[tex]\longrightarrow \tt \: 40 = 2(12 + b)[/tex]

We got an equation.By this method we can easily find the breadth/width of the pool.

Solve this equation:

[tex]\longrightarrow \tt40 = 2b + 24[/tex]

Flip the equation:

[tex]\longrightarrow \tt2b + 24 = 40[/tex]

[tex]\longrightarrow \tt2b = 40 - 24[/tex]

[tex]\longrightarrow \tt2b = 16[/tex]

Divide both sides by 2:

[tex] \tt\longrightarrow \cfrac{2b}{2} = \cfrac{16}{2} [/tex]

[tex]\tt\longrightarrow \cfrac{ \cancel2 {}^{1} b}{ \cancel2} = \cfrac{ \cancel{16} {}^{8} }{ \cancel2} [/tex]

[tex]\longrightarrow \tt1b = 8[/tex]

[tex]\longrightarrow \tt{b} =\boxed{\tt 8 \: feet}[/tex]

Hence, the breadth/width of the pool would be 8 ft./feet .
