What is the probability of picking a prime number and then picking a prime number?

Simplify your answer and write it as a fraction or whole number.

My reasoning is the mention of PHOTOPERIODISM. Photoperiodism means the reaction to length of a day or night cycle, since fall is the beginning of shorter days and longer nights, it is only reasonable that the answer is that THey bloom when the nights are longer.

Answer:

The distance between the plane and the base of the airport = 103339.14 ft

Step-by-step explanation:

Consider the diagram attached.

We can notice that the a triangle (ABC) can be formed between the plane, the airport, and a vertical line drawn from the ground to the plane showing its altitude.

The angle of depression is 14 degrees. This means that angle BAC is 90 - 14 = 76 degrees.

From triangle laws, we will have that [tex]cos 76 = \frac{Altitude}{AC}[/tex]

[tex]AC = \frac{25000}{(cos 76)} = 103339.14 ft[/tex]

Hence, the distance between the plane and the base of the airport = 103339.14 ft

The diagonal distance between the plane and the base of the airport is 103339.14 ft.

This situation forms a right angle triangle.

The plane is flying at an elevation of 25000 ft.

The elevation is the height or opposite side of the triangle.

The diagonal distance between the plane and the base of the airport is the hypotenuse of the triangle.

Therefore, using trigonometric ratio,

sin 14° = opposite / hypotenuse

sin 14° = 25000 / d

d = 25000 / sin 14

d = 25000 / 0.2419218956

d = 103339.137361 ft

Therefore, the diagonal between the plane and the base of the airport is  103339.14 ft.

Step-by-step explanation:

Answer:

answer is 60

Step-by-step explanation:

because if the angle is 60 degrees anywhere in the triangle means its an equilateral triangle making all the angles 60 degrees

Answer:

60 degrees

Step-by-step explanation:

Every Triangle has an angle of 180 degrees

so if we add all of the written angles which is 25 + 35 + 60 = 120

we take 180 degrees and subtract it with the previous answer (120)

180 - 120 = 60

Therefore it is 60 degrees

Answer:

3017.5 cm³

Step-by-step explanation:

The volume of a rectangular prism is V = l × w × h

Here the length is 14.2, the width is 12.5, and the height is 1

Plugging these into our formula we get V = (14.2)(12.5)(1) = 177.5 cm³

Since there are 17 CD cases stacked on top of each other, we will multiply our number by 17 which gives us (177.5)(17) = 3017.5 cm³

Complete question:

The park closes at 2:30 P.M. There is a 15−minute break between each game played at the park, and each game takes the same amount of time as Hamid's soccer game. How many more games can be played before the park closes? Hamid's soccer game time is 7:00 to 9:15

Answer:

2 more games can be played before the park closes.

Step-by-step explanation:

Given that Hamid's soccer game time is from 7:00 to 9:15 and there's a 15 minute break between games played, the next game time would be: 9:15 + 15 = 9:30

The time for each game would be calculated as:

stop time - start time = 9:15 - 7:00 = 2:15.

Thus, each game time = 2hrs 15mins

The next game time would be:

9:30 + 2:15 = 11:45

This means the next game would be from 9:30 to 11:45

After this, there would be another game(a second extra game) since the park closes at 2:30PM.

Therefore, the next game time would be:

11:45 + 15 mins break = 12:00

The game duration =

12:00 + 2hrs 15 mins = 14:15 or 2:15PM

Considering the fact that the park closes by 2:30 PM, 2 more games will be played.

Answer:

Area of circle = πr²

New doubled area = πR² ( r ≠ R )

As it is double of older area :

πR² = 2πr²

R² = 2r²

R = √2r

Thus we have to multiply the radius to √2 to double its area

Answer:

137 toys

Step-by-step explanation:

You take the number of dogs = 15

and how many things each dog needs = a collar, bowl, and toy

and you multiply 15 by three to get the number of collars, bowls, and toys each dog needs. Then repeat this process and add all of your answers

Dog = 60

Cat = 88

Rabbit = 4

88 + 60 + 4 = 137

(If the collar, and bowls don't count as toys then just message me and I will redo the math for you.)

Answer:

A

Step-by-step explanation:

Hence, the option (A) is the correct answer i.e., On a coordinate plane, two lines intersect at one point

What are the one solution ?

One Solution Equation is when an equation has only one solution. This means that when you solve an equation, the variable can only be subsituted by one number to make an equation true.

So, when the two lines passes and intersect at one point it forms one solution so that is why option (A) is correct i.e., On a coordinate plane, two lines intersect at one point.

Hence, the option (A) is the correct answer i.e., On a coordinate plane, two lines intersect at one point

$857.58 is the price of car after 4 years.

percentage, a relative value indicating hundredth parts of any quantity.

Given,

Dan buys a car for £900.

It depreciates at a rate of 1.2% per year

We need to find the cost of car after 4 years.

1.2/100=0.012

Now multiply 0.012 with 900

10.8

So for first year it will be 900-10.8=889.2

0.012×889.2

10.67

For second year 889.2-10.67=878.53

0.012×878.53=10.54

For third year 878.53-10.54=867.99

0.012×867.99=10.41

For fourth year 867.99-10.41=857.58

Hence, after 4 years the price of car will be 857.58.

Answer:

lateral surface area is 160.14 square cm.

Total surface area is 273.16  square cm  

Step-by-step explanation:

Lateral surface area of cone is given by [tex]\pi rl[/tex]

where r is radius of cone

and l is slant height of cone.

l = 85 millimetres

we know that 10 millimetres is equal to 1 cm

Thus 85 millimetres is equal to 8.5 cm

Thus slant height(l) in cm is 8.5[tex]\pi rl\\=>\pi 6*8.5\\=> 3.14*51\\=>160.14[/tex]

we will use value of [tex]\pi[/tex] as 3.14

Diameter of cone = 12 cm

we know that radius is equal to half of Diameter

radius of given cone = 1/2 *Diameter = 1/2 * 12 = 6 cm.

Thus lateral surface area of cone is given by

[tex]\pi rl\\=>3.14*6*8.5\\=>153[/tex]

Thus, lateral surface area is 160.14 square cm.

Area of base of cone will be area of circular base

area of circle is given by [tex]\pi r^2[/tex]

Thus area of base is given below

[tex]\pi r^2\\=>3.14*6^2\\=>113.04[/tex]

area of base is 113.04 square cm

Total surface area of cone is sum of area of base and lateral surface area

Total surface area = 160.14+113.04 = 273.16  square cm.

Answer:

The result is

x + b/2a= ±√[(b² - 4ac)/2a]

Step-by-step explanation:

In the derivation of the quadratic formula by completing the square, the equation is created by forming a perfect square trinomial

ax² + bx + c = 0

x² + (b/a)x + c/a = 0

x² + 2(b/2a)x + b²/4a² - b²/4a² + c/a = 0

(x + b/2a)² - b²/4a² + c/a = 0

(x + b/2a)² = b²/4a² - c/a

(x + b/2a)² = (b² - 4ac)/2a

Apply square roots to both sides

x + b/2a= ±√[(b² - 4ac)/2a]
