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:

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.

Explanation:

Steve correctly computed the change in x to be 2, and the change in y to be 6. However he put 2 in the slope formula for Δy (the change in y), and 6 for Δx. That is, Steve reversed the values of Δx and Δy.

The actual slope is ...

  slope = Δy/Δx = 6/2 = 3

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

Answer:

$12

Step-by-step explanation:

when d = 0,  F = 110

when d = 100, F = 110 + (0.12 x 100) = 122

when d = 200, F = 110 + (0.12 x 200) = 134

etc.

Therefore, increase in price for every 100 meters climbed = 134 - 122 = 122 - 110 = 12

Answer:

4,356 milliliter

Step-by-step explanation:

If 1 liter = 1,000 milliliter

Formula: Multiply the volume value by 1000

Then, 4 liter = 4,000 milliliter

4,000 + 356=4,356

Hence, there are 4,356 milliliter in 4 liters, 356 milliliter.

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)

Angles and arcs' lengths are related to each other. The length of the minor arc SV is given by: Option A: [tex]20\pi \: \rm inches[/tex]

Whole circumference is covered by 360 degrees rotation.

[tex]2\pi^c = 360^\circ = \text{Full circumference}[/tex]

The superscript 'c' shows angle measured is in radians.

If radius of the circle is of r units, then:

[tex]1^c \: \rm covers \: \dfrac{circumference}{2\pi} = \dfrac{2\pi r}{2\pi} = r\\\\or\\\\\theta^c \: covers \:\:\: r \times \theta \: \rm \text{units of arc}[/tex]

The complete problem specifies radius of the circle as 24 in. and

θ = 5pi/6

Thus, we get the measurement of the arc length that angle covers as:

[tex]r \times \theta \: \rm inches = 24 \times \dfrac{5\pi}{6} = 20\pi \: \rm inches[/tex]

Thus, the length of the minor arc SV is given by: Option A: [tex]20\pi \: \rm inches[/tex]

Step-by-step explanation:

Trust me, I took Algebra last year and did a similar problem.

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.

Percent counts the number of a quantity compared to another quantity's 100 amount. The amount each person would pay is given by: Option D: $9. 75

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

[tex]\dfrac{a}{100} \times b[/tex]

For the given case,

Bill for lunch = $32.50

Tip  = 20% of bill = [tex]\dfrac{32.50}{100} \times 20 = \dfrac{32.50}{5} = 6.50[/tex] (in dollars)

Total amount = Bill + Tip = $39

This amount has to be divided in 4 equal part.

Thus, each part of those 4 parts would be [tex]\dfrac{39}{4} = 9.75[/tex] (in dollars).

Thus, the amount each person would pay is given by: Option D: $9. 75

Answer:

JL ≈ 3.1

Step-by-step explanation:

Using the cosine rule

with JL = k , JK = l , KL = j , then

k² = j² + l² - (2jlcosK )

   = 6² + 8² - ( 2 × 6 × 8 × cos20° )

    = 36 + 64 - (96cos20°)

    = 100 - 96cos20° ( take square root of both sides )

k = [tex]\sqrt{100-(96cos20)}[/tex] ≈ 3.1 ( to the nearest tenth )

that is JL ≈ 3.1
