Here is another one y’all smart I’m not thanks for all your helppp people I don’t know.

Answer:

6.55 cm

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, acute, scalene, obtuse, right and equilateral triangle.

Cosine rule is used to show the relationship between sides and angles of a triangle. If a, b, and c are sides of a triangle, while A, B, and C are angles opposite to the corresponding sides. Then:

c² = a² + b² - 2ab*cos(C)

Given that PR = 13 cm, PQ = 12 cm and angle QPR = 30°, hence:

QR² = PR² + PQ² - 2(PR)(PQ)cos(∠QPR)

QR² = 13² + 12² - 2(13)(12)cos(30) = 169 + 144 - 270

QR² = 43

QR = 6.55 cm

Answer:

Theoretical probability is based upon what is expected when rolling two dice, as seen in the "sum" table at the right. The theoretical probability of rolling an 8 is 5 times out of 36 rolls. The theoretical probability = 5/36 ≈ 13.9%. 3) The experiment rolled more 8's than would be expected theoretically.

Step-by-step explanation:

The theoretical probability of not rolling a 2 is 5/6.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

Assuming a fair six-sided die, the probability of rolling a 2 is 1/6.

Therefore, the probability of not rolling a 2 on a single roll of the die is:

P(not rolling a 2) = 1 - P(rolling a 2) = 1 - 1/6 = 5/6

Thus,

The theoretical probability of not rolling a 2 is 5/6.

The answer is $10 per adult ticket, and $7 per child ticket. Now lets figure out how to get to that answer. Let's create a chart to help visualize this.

- - - - -A- - - - - C- - - - -T- - - - -

    :     2    :      4     :   $48    :    

    :     5    :        2   :   $64    :                Key:

    :           :             :               :                      A = Adult ( The Y)

    :           :             :               :                      C = Child ( The X)

    :           :             :               :                       T= Total

When we look at it, the total cost is less then what the adult would be when multiplied by 10, and you WOULD have to add the children cost to the adult cost, so lets try it.

Lets do the 2 adult tickets first, 2 x 10 is 20. Now we do 48 - 20 to get how much the cost of the children's 4 needs to equal. We get 28 as the answer. Now we have to do 28 divided by 4, we get 7 as that answer.

Now lets plug that in to the $64 problem and see if that gets us the correct answer.

So the amount of adult tickets for this problem is 5, so we do 5 x 1 which is 50.

Now the amount of children tickets is 2, so lets do 2 x 7, which equals 14.

Now to test if it gets us the correct answer, to do that we do 50 + 14, that equals what we want it to, 64.

Therefor, the correct answer is $10 per adult ticket, and $7 per child ticket.

The offered statement states that a rectangle's basic shape has a 45-square-foot area.

An example of a quadrilateral with equal and parallel opposite sides is a rectangle. It is a polygon with four sides and four angles that are each 90 degrees. A parallelogram is a polygon with only two dimensions. To be a square, a rectangle's sides must all have the same length, hence not all rectangles are squares.

Area of rectangle = Length (L) * Width (W)

Area of rectangle = \(\sqrt{15*9*5*3}\)

= \(\sqrt{3*5*3*3*5*3}\)

= 3*5*3

= 45

Consequently, the area of a rectangle in its most basic form is 45.

The expected value of sales at a price of $1 is 11.015 for the given regression demand equation.

In the regression demand equation e(log(sales | price)) = 11.015 - 2.442 log(price), you want to find the expected value of sales at a price of $1. To find the expected value of sales, you need to substitute the given price of $1 into the equation and solve for the sales. Substituting the price of $1 into the equation, you get: e(log(sales | 1)) = 11.015 - 2.442 log(1). Since log(1) = 0, the equation simplifies to: e(log(sales | 1)) = 11.015 - 2.442 * 0, e(log(sales | 1)) = 11.015
Therefore, the expected value of sales at a price of $1 is 11.015.

Thus, Stacy flew at speed of -  185 miles per hour for 2 hours and 210 miles per hour for 3 hours.

Speed is the rate at which a distance changes over time. The speed is equivalent to s = D/T if D is the object's distance in time T. The units are the same as for velocity.

Distance =  speed * time.

Given data:

t₁ = 2 hours: s₁ =  x miles per hour

t₂ = 3 hours; s₂ = (x + 25) miles per hour

Total distance d = d₁ + d₂ =  1000 miles.

Thus,

d = d₁ + d₂

d = t₁ *s₁ + t₂ * s₂

1000 = 2x + 3(x + 25)

On simplification:

1000 = 5x + 75

5x = 1000 - 75

x = 925/5

x = 185 miles per hour for 2 hours

(x + 25)  = 185 + 25 = 210 miles per hour for 3 hours.

Thus, Stacy flew at a rate of -

Step-by-step explanation:

The value of the collection originally was $1,000,000

What was the original value of the collection?

The original value of the collection is not known, hence, it is represented by X

The increase in value by $50,000 means that the value is X+$50,000

Now, when the error was discovered, it is now worth half of the  value previously

The new value is (X+$50,000)*0.5

New value=(X+$50,000)*0.5

The new value at this point is $525,000

$525,000=(X+$50,000)*0.5

$525,000/0.5=X+$50,000

$1,050,000=X+$50,000

The formula for the number of ways to seat r of n people around a circular table, where seatings are considered the same if every person has the same two neighbors without regard to which side these neighbors are sitting on is given by (n-1)!/[r!(n-r)!].

To understand this formula, we can start with the case where we are seating n people in a row. There are n! ways to do this. However, in the case of a circular table, we have to divide by n to account for rotations. Now, we have to account for the fact that two seatings are considered the same if every person has the same two neighbors, so we have to divide by 2r to account for these duplicates. Finally, since the ordering of the remaining people doesn't matter, we have to divide by (n-r)! to account for this. This gives us the formula (n-1)!/[r!(n-r)!].

Answer:

24 years old

Step-by-step explanation:

Let the age of Blake be x and the age of Heather by y then...

x=7+y

7+x+7+y=55

Notice we are adding additional 7s because the question states "in 7 years"

Simplify the second equation...

7+x+7+y=55

14+x+y=55

Subtract 21 from both sides

x+y=41

Solve using substitution (substitute 7+y for x since x = 7+y)

7+y+y=41

Combine like terms

2y+7=41

Subtract 7 from both sides

2y=34

Divide both sides by 2

y=17

x=7+17=24

b) 9.76 × 10³ as an ordinary number is 9,760.

c) 201.38 × 10° in standard form is 201.38.

a) To write 43,250,000 in standard form, we need to express it as a number between 1 and 10 multiplied by a power of 10. Since 43,250,000 can be written as 4.325 × 10^7, the standard form of 43,250,000 is 4.325 × 10^7.

b) To write 9.76 × 10³ as an ordinary number, we need to multiply 9.76 by the power of 10. In this case, since the power of 10 is positive 3, we move the decimal point three places to the right. Thus, 9.76 × 10³ becomes 9,760.

c) To write 201.38 × 10° in standard form, we need to express it as a number between 1 and 10 multiplied by a power of 10. Since the power of 10 is 0, the number remains the same. Therefore, the standard form of 201.38 × 10° is simply 201.38.

There are 55,440 possible 5-permutations of 11 distinct objects.

There are 55 5-permutations of 11 distinct objects.

To find the number of 5-permutations of 11 distinct objects, you need to use the formula for permutations, which is n!/(n-r)!, where n represents the total number of objects and r represents the number of objects to be arranged.

In this case, n = 11 (total number of distinct objects) and r = 5 (number of objects to be arranged).

Calculate (n-r)!
(11-5)! = 6!

Calculate 6!
6! = 6 × 5 × 4 × 3 × 2 × 1 = 720

Calculate n!
11! = 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 39,916,800

Divide n! by (n-r)!
39,916,800 ÷ 720 = 55,440

Answer: 18

Step-by-step explanation:

:)))) NO NEED SOLUTION.

The distance the drone has flown after both cars get back to where they started is equal to the length of the diagonal of the square, which is approximately 0.7071.

Since the perimeter of the square is 2, each side of the square has a length of 0.5. Therefore, the total distance around the square is 2 x 0.5 = 1.

Both cars start at the same time and drive clockwise on the perimeter of the square, so they will meet each other exactly halfway around the square. At this point, the drone at the midpoint of the two cars will have flown a distance equal to half the perimeter of the square, which is 0.5.

After the cars complete one full lap around the square and return to where they started, they will have each traveled a distance of 1. Therefore, the distance the drone has flown at this point is equal to the distance between the two cars, which is also equal to the diagonal of the square. Using the Pythagorean theorem, we can calculate the length of the diagonal as follows:

d^2 = 0.5^2 + 0.5^2
d^2 = 0.25 + 0.25
d^2 = 0.5
d = sqrt(0.5)

Therefore, the distance the drone has flown after both cars get back to where they started is equal to the length of the diagonal of the square, which is approximately 0.7071.
