show that the two quadrilaterals are congruent​

Answers

The two quadrilaterals JKLQ and LMNP are congruent.

What is congruent quadrilaterals?

You will always have two opposite pairs of parallel sides if the two pairs of opposite sides in a quadrilateral are congruent. They must measure similarly to be considered congruent. Consider this: two congruent sides must always maintain the same separation between the opposing lines to maintain the other pair of opposite sides.

To prove that all corresponding pairs of sides and angles are congruent, you must put the interior angles and sides of one quadrilateral in correspondence with those of another.

For the given quadrilaterals JKLQ and LMNP it is given that,

JK ≅ MN, JQ ≅ NP, QL ≅ PL and  KL ≅ ML

Also,

∠J ≅ ∠N, ∠Q ≅ ∠P, ∠K ≅ ∠M, and ∠L is the common for both quadrilaterals.

Here the corresponding sides and angles of the quadrilaterals are congruent.

Hence, the two quadrilaterals JKLQ and LMNP are congruent.

Travelling at 24 km/h on a snowmobile makes an air temperature of 4°C feel like -6°C because of the wind chill. What is the difference in these temperatures?

Answers

The difference in temperature is currently six degrees Celsius. Therefore, the appropriate reaction is six degrees Celsius.

What is the difference in temperatures?

When two independent temperature readings are subtracted, or when calculating the amount of temperature rise or fall, the result is a temperature difference, also referred to as a delta temperature (T).

Simply subtract the smaller amount from the larger one to determine the difference in temperature, in this case 19 degrees Celsius from 25 degrees Celsius. We now have a six-degree Celsius temperature difference as a result. Therefore, six degrees Celsius, is the appropriate response.

Due to the varied amounts of radiation the Earth receives from the Sun at various periods of the year, there are variations in climate all over the world. The equator receives more heat from the Sun than the north and south poles, where the angle of the Sun's beams is lower.

What is a transformation in geometry?

A geometric transformation involves either a change in location, size, or orientation or a combination of changes of a geometric figure.

The possible polygon with vertices in the question obtained from a similar question online and drawn using MS Excel is attached;

The vertices of the polygon are;

The coordinates of the vertices of Figure G; (-2, 7), (-6, 3), (-1, 5), (-1, 1)

The coordinates of the corresponding vertices of Figure H; (5, 7), (9, 3), (4, 5), (4, 1)

The y-values of figure G and figure H are the same, while the x-values changes both value and sign.

The coordinates of the point (x, y), following a reflection about the y-axis is the point (-x, y)

Therefore, the possible transformation that maps figure G unto figure H includes a reflection across the y-axis;

The coordinates of the vertices of figure G following a reflection about the y-axis are;

Image of figure G following a reflection about the y-axis; (2, 7), (6, 3), (1, 5), and (1, 1)

The transformation that maps the image produced by the reflection and figure H are;

At [tex]$5 \mathrm{pm}$[/tex] the distance between the ships is changing at the speed of [tex]$\mathbf{3 0 . 2 1}$[/tex] knots

A large container holds 4.7 gallon of water. Use the following information to convert this amount of water to liters.1 gallon =4 quarts 1L =1.057 quarts

Answers

Answer:

Step-by-step explanation:

To convert the amount of water in gallons to liters, we need to first convert the number of gallons to quarts and then convert the number of quarts to liters.We know that 1 gallon is equal to 4 quarts, so 4.7 gallons is equal to 4.7 gallons * 4 quarts/gallon = 4.7*4=18.8 quarts.We also know that 1 liter is equal to 1.057 quarts, so to convert the number of quarts to liters, we can divide the number of quarts by 1.057 quarts/liter: 18.8 quarts / 1.057 quarts/liter = 18.8/1.057=17.8 liters.Therefore, 4.7 gallons is equal to 17.8 liters.

Find the volume of a cone with a radius of 6.5 inches and a height of 12 inches.
A) 670.2 in ³
B) 530.9 in³
C) 414.7 in ³
D) 513.1 in³

Answers

To find the volume of a cone, we can use the formula:

Volume = (1/3) * pi * r^2 * h

Where r is the radius of the base of the cone, h is the height of the cone, and pi is approximately equal to 3.14.

Plugging in the given values, we have:

Volume = (1/3) * 3.14 * 6.5^2 * 12

= (1/3) * 3.14 * 42.25 * 12

= (1/3) * 513.1

= 171.03

Therefore, the volume of the cone is approximately 171.03 cubic inches, which is closest to answer choice C, "414.7 in ³."

Think about the number 9. When the number 3 is multiplied by itself, the result is 9. This can be expressed as either 32 or 3 3. We refer to this as a square since there is a 2 exponent. When the exponent is now 1/2, the square root of the integer is being discussed. For instance, when n is a positive integer, n = n1/2

The value of a number's power 1/2 is the number's square root. It is the number whose product by itself yields the original number, to put it another way. It is symbolised by the character "." The number behind the square root sign is referred to as the radicand, whereas the square root symbol itself is known as a radical.

What is a rectangle?

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Main body:

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Let's say the width of metal w then the length will be w + 5

Now if we cut 1 inch square from the corner of the metal and then fold then the resultant cuboid will have;

Length = w+5 - 2 -= w + 3

Width = w - 2

Height = 1

So,

Volume = (w+3)(w-2)1

456 = w² - 2w + 3w - 6

w² + w - 462 = 0

By solving this

w = 21 so width will be 21 and length will be 21 + 5 = 26.

Hence "The width of the piece of metal will be 21 inches while the length will be 26 inches".

Option 1: PV annuity factor, 0.5%, 360 periods = 166.79161

Option 2: PV annuity factor, 0.375%, 180 periods = 130.7201

Monthly payment option 1 = $300,000 / 166.79161 = $1,798.65

Step-by-step explanation:

Lets call the speed of the eastbound train E and the speed of the westbound train W.

E = W - 18

distance travelled  = speed * time

thus

Wt + Et = 320

Wt + (W - 18)t = 320

factor out t

t * (2W - 18) = 320

t = 2 hours

2 * (2W - 18) = 320

2W - 18 = 160

2W = 178

W = 89

Then, E = (89) - 18 = 71 mph

if sinθ 1÷2 and θ is in quadrant , evaluate each expression. a) sin 2θ b) cos 2θ c) tan 2θ

Answers

The values of sin 2θ, cos 2θ, and tan 2θ are:

a) sin 2θ = √(3)/2

b) cos 2θ = 1/2

c) tan 2θ = √(3)

What is a quadrant?

Generally, If sin θ = 1/2 and θ is in quadrant I, then θ is equal to 30 degrees.

To evaluate each expression, we can use the trigonometric identities:

a) sin 2θ = 2 * sin θ * cos θ

= 2 * (1/2) * (√(3)/2)

= √(3)/2

b) cos 2θ = cos^2 θ - sin^2 θ

= (√(3)/2)^2 - (1/2)^2

= (3-1)/4 = 1/2

c) tan 2θ = (2 * tan θ) / (1 - tan^2 θ)

= (2 * (√(3)/3)) / (1 - (√(3)/3)^2)

= 2 * √(3) / (4 - 3)

= √(3)
