Answer:

Probability [Randomly choose plant Juan's mother want] = 3 / 5

Step-by-step explanation:

Given:

Total number of plant in store = 30 plants

Number of plant kind Juan's mother want = 18

Find:

Probability [Randomly choose plant Juan's mother want]

Computation:

Probability of an event = Number of favorable outcome / Total number of outcomes

Probability [Randomly choose plant Juan's mother want] = Number of plant kind Juan's mother want / Total number of plant in store

Probability [Randomly choose plant Juan's mother want] = 18 / 30

Probability [Randomly choose plant Juan's mother want] = 3 / 5

Answer: 102.5

Step-by-step explanation:

Area of triangle: 8*6=48, 48/2=24

Area of semicircle: 2pir^2=2pi(5)^2=157

Because its semi circle it is 157/2 which equals 78.5

Total area:24+78.5=102.5

Answer:

102.5

Step-by-step explanation:

Semi circle = 78.54 ≈ 78.5

Using formula A = πr²

Area triangle = 24

Using formula A = 1/2(bh)

Sum = 78.5 + 24 = 102.5

Answer:

2700 in^2

Step-by-step explanation:

30x30x3(which is how they are rounding π) = 2700 in ^2

Step-by-step explanation:

here's your solution

==> Both traingle are congruent

==> BC = BD. [ c.p.c.t ]

==> x + 8 = 3x - 14

==> x - 3x = - 14 - 8

==> - 2x = - 22

==> x = 22/2

==> x = 11

now CB = x + 8 = 11 + 8

CB = 19

Answer:

x=9, y=-4. (9, -4).

Step-by-step explanation:

2x+5y=-2

4x+7y=8

--------------

-2(2x+5y)=-2(-2)

4x+7y=8

---------------------

-4x-10y=4

4x+7y=8

--------------

-3y=12

y=12/-3

y=-4

2x+5(-4)=-2

2x-20=-2

2x=-2+20

2x=18

x=18/2

Median:9.5

Mean:16.5

Step-by-step explanation:

Median: Put them in order, find the middle, since there is two median we add them together, then divide them by 2 and there's your answer.

Mean: Add the numbers: 0+ 6+ 13+47= 66

Divide by how many numbers (there are 4 numbers): 66/ 4= 8

Answer:

[tex]\$13,107.96[/tex]

Step-by-step explanation:

Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.

Therefore, we can set up the following equation to find the new balance after 2 years:

[tex]\text{New balanace}=10,000\text{ (old balance)}\cdot 1.07\cdot 1.07\cdot 1.07\cdot 1.07,\\\text{New balanace}=10,000\cdot 1.07^4=\boxed{\$13,107.96}[/tex]

Answer:

[tex]20.25\pi\:\mathrm{m^2}[/tex]

Step-by-step explanation:

Formulas to know:

Since we know the circumference, we can use formula for the circumference of a circle to find the circle's radius:

[tex]9\pi=2r\pi,\\9=2r,\\r=4.5[/tex]

Now we can plug in [tex]r=4.5[/tex] into the formula for an area of a circle:

[tex]A=4.5^2\pi=\boxed{20.25\pi\:\mathrm{m^2}}[/tex]

Answer:

20.25 pi

Step-by-step explanation:

The circumference of a circle is given by

C = 2 * pi *r

9 pi = 2 * pi *r

Divide each side by 2pi

9pi / 2 pi = 2 pi r / 2 pi

4.5 = r

Now we can find area

A = pi r^2

   = pi ( 4.5)^2

     20.25 pi

Answer:

y = (x - 2)² + 9

Step-by-step explanation:

To obtain the equation in vertex form use the method of completing the square.

Add/ subtract ( half the coefficient of the x- term)² to x² - 4x

y = x² + 2(- 2)x + 4 - 4 + 13

  = (x - 2)² + 9 ← in vertex form

Answer:

vertex form : y=(x-2)^2+9

Step-by-step explanation:

To convert a parabola from standard form y=x^2-4x+13 to vertex form, we complete the square.

first, complete the square using the x-terms, use the constant term to adjust and make a perfect square.

y=  x^2-4x+4   +  9

Factor the first three terms on the right-hand side.

y=(x-2)^2 + 9

the resulting express is then the vertex form, which means that

the vertex is at (x-2) = 0, x=2, and at y=9.  

Answer:

x = 28

Step-by-step explanation:

The 2 radii of the circle form an isosceles triangle with base angles congruent, both 59°

The angle at the vertex O is then

180° - (59 + 59)° = 180° - 118° = 62°

The angle between the tangent and the radius is 90°

Then

x = 180 - (90 + 62) ← sum of angles in a triangle

x = 180 - 152 = 28
