Answer:

∆ adc is congruent to ∆ abc by asa congruence rule where CA is common side,

so CD and CB are congruent therefore angle cbe is same as angle cde

so ∆ bce and ∆ dce are congruent by ASA congruence rule

The triangle BCE is congruent to triangle DCE if ∠1 is congruent to ∠2 and ∠3 is congruent to ∠4.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

For the figures to be congruent they must be the same size and shape or one could mirror the other since they mirror each other and are the same size and shape they are congruent.

In triangle ∆ ADC and ∆ ABC

∠2 = ∠1

∠4 = ∠3

Thus, ∆ ADC ≅ ∆ ABC

∆ ADC is congruent to ∆ ABC by ASA congruence rule where CA is common side.

Also, CD and CB are congruent therefore angle CBE is same as angle CDE.

Similarly, ∆ BCE and ∆ DCE are congruent by ASA congruence rule.

The triangle BCE is congruent to triangle DCE if ∠1 is congruent to ∠2 and ∠3 is congruent to ∠4.

Answer:

1 by 4

Step-by-step explanation:

The computation of the probability is as follows

Here we assume the moves in a complex numbers i.e. a, b and c

Now the frog begins with the starting point.

So it would become easy to represent the exactly one element in a set that has lower or equal than 1

|a + b + c| , |a + b - c|, |a - b + c|, |a - b- c|

So here the probability is 1 by 4

Answer:

Costo  unitario= $3

Step-by-step explanation:

Dada la siguiente información:

Entrada= $4.5

Cantidad de entradas de más= 2

Cantidad de amigos que pagan= 3

Primero debemos calcular el total a pagas de más:

Total a pagar de más= 2*4.5= $9

Ahora, cuánto debe pagar cada uno:

Costo unitario= costo total / cantidad de personas

Costo unitario= 9/3

Costo  unitario= $3

Answer:

196 patches

Step-by-step explanation:

We are told that the quilt is made out of square pieces that have a perimeter of 24 square inches.

This means that, length of one side = 24/4 = 6 inches.

Now since Morgan is making a square quilt with an area of 49 square feet for her nephew, let's convert 6 inches to ft.

6 inches = 6 × 1/12 = 0.5 ft

Thus, the area of a small quilt = 0.5 × 0.5 = 0.25 ft²

Number of patches = 49/0.25 = 196 patches

Step-by-step explanation:

You answer goes to minus infinity. There is no answer and you are correct.

Answer:

simplify a power of a power by multiplying the exponents and keeping the same base.

Step-by-step explanation:

Velocity is a vector, so it has a magnitude and direction.

Speed is its magnitude, which is obtained from

|〈-3, 4〉 m/s| = √((-3 m/s)² + (4 m/s)²) = √(25 m²/s²) = 5 m/s

Its direction is an angle θ made with the positive horizontal axis, satisfying

tan(θ) = (4 m/s) / (-3 m/s) = -4/3   →   θ = arctan(-4/3) + 180°n

where n is any integer. Now you have to consider that the x coordinate is negative and the y coordinate is positive, so 〈-3, 4〉 points into the second quadrant, and we get an angle there for n = 1 of about

θ ≈ 126.87°

Alternatively, you can use the vector 〈1, 0〉 in place of the axis, then compute the angle by relating it to the dot product, so θ is such that

〈-3, 4〉 • 〈1, 0〉 = |〈-3, 4〉| |〈1, 0〉| cos(θ)

(-3)•1 + 4•0 = √((-3)² + 4²) • √(1² + 0²) cos(θ)

-3/5 = cos(θ)   →   θ = arccos(-3/5) + 360°n

where again, n is any integer, and we get the same solution θ ≈ 126.87° in the second quadrant when n = 0.

Step-by-step explanation:

took the test egde 2021

The difference between the new, colder temperature and the original temperature is 30 ° C.

"Temperature, measure of hotness or coldness expressed in terms of any of several arbitrary scales and indicating the direction in which heat energy will spontaneously flow—i.e., from a hotter body (one at a higher temperature) to a colder body (one at a lower temperature). Temperature is not the equivalent of the energy of a thermodynamic system; e.g., a burning match is at a much higher temperature than an iceberg, but the total heat energy contained in an iceberg is much greater than the energy contained in a match. Temperature, similar to pressure or density, is called an intensive property—one that is independent of the quantity of matter being considered—as distinguished from extensive properties, such as mass or volume."

Given,

The old temperature is = 18°C

The new temperature is = -12°C

The difference in temperature is [tex](-12\°C - 18\°C) = 30\°C[/tex]

Answer:

Either increase the number of acres that can be used for strawberry fields (by buying more land)..If we use the same numbers from earlier, then the farmer should use approximately 16.65 acres of land (or just 17 acres of land)

So if the farmer has 17 acres of land or more, then he will make more than $70,000 per year

Step-by-step explanation:

Use the proportions from earlier

We have the point (5, 21000)

70,000/21,000 = 3.3

To find the x-value multiply 3.3 by 5

3.3 * 5 = 16.65

We can even use the other point's values to find the exact same answer

Point (3.5, 14700)

70,000/14,700= 4.7619047619

4.7619047619 * 3.5 = 16.66 (literally about the same)

Answer:

225 words

Step-by-step explanation:

In order to find the answer to this question we have to find how many words she writes in 1 minute. To do this you need to divide 90 words by 4 minutes:

(90)/4 = 22.5 words/minute

Now that the words per minute is found, we can multiply it by the 10 minutes to find how many words she can write in 10 minutes:

(22.5)(10) = 225

Therefore, Sara can type about 225 words in 10 minutes.

Determine the standard deviation

Standard Deviation (SD) is calculated as:

Answer:

The population of deer at any given time = 200(e^0.03t)  ÷ (1.5 + (e^0.03t))

Step-by-step explanation:

This is an example of logistic equation on population growth

carrying capacity, k = 200

Rate, r = 3% = 0.03

Initial Population, P1 =  80

P(t) =?

P(t) = (P1 (k)(e^rt)) ÷ (k- P1 + P1(e^rt))

P(t) = (80 (200)(e^0.03t)) ÷ (200 - 80 + 80(e^0.03t))

     = (16000(e^0.03t))  ÷ (120 + 80(e^0.03t))

      = 200(e^0.03t)  ÷ (1.5 + (e^0.03t))

Question:

The grocery store has 20% off from the original price on cereal. The equation for finding the sale price would be y = x - (.20x). What is the sale price if the cereal cost $4.00?

Answer:

The sales price is $3.20

Step-by-step explanation:

Given

[tex]y = Sales\ Price[/tex]

[tex]x = Cost[/tex]

[tex]y = x - (0.20x)[/tex]

Required

Determine y when x = 4.00

To do this, we simply substitute 4.00 for x in [tex]y = x - (0.20x)[/tex]

[tex]y = 4.00 - (0.20 * 4.00)[/tex]

[tex]y = 4.00 - 0.80[/tex]

[tex]y = 3.20[/tex]

Hence, the sales price is $3.20

The number of yards in 1 foot is 3 thus 20 packages can be wrapped.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

As per the given,

Length of ribbon = 20 yards

Each package required = 3 feet

Since 1 yard = 3 feet so,

Each package required = 1 yard

The number of packages that can be wrapped = 20/1 = 20

Hence" The number of yards in 1 foot is 3 thus 20 packages can be wrapped".
