Using formula:

[tex]\to \bold{C =2\pi r}\\\\[/tex]

put the value in the above formula:

[tex]=2\times \frac{22}{7} \times 62.5\\\\=\frac{2750}{7}\\\\=392.857143 \approx 393[/tex] ft

Answer:

11.25 feet

Step-by-step explanation:

The model is 1/5 or 0.2 smaller than the original water tower

0.2 x water tower height = 2.25

water tower height = 2.25 / 0.2 = 11.25

Answer:

11/21.

BG has a total of 11 points (when you include 0), and there are 21 points total. 11/21 cannot be simplified, your final answer is 11/21.

The required probability is 11/21 that one point will be on BG.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

We have been given that the number line which has a point is chosen at random on AK.

As per the given question, the required solution would be as:

Since BG has a total of 11 points (when you include 0),

so, the number of favorable outcomes : 11

There are 21 points in total, then the total number of outcomes : 21.

So, the probability that one point will be on BG would be as:

⇒ 11/21

Answer:

[tex]\frac{11}{850}[/tex]

Step-by-step explanation:

Let's see

The probability of the first card being a spade is 13/52 (as there's 13 spades in the deck.

The probability for the second card is 12/51 (because there's 12 spades left in 51 cards total).

The probability for the third is - you guessed it! - 11/50

so the total probability is:

[tex]\frac{13}{52} \cdot \frac{12}{51} \cdot \frac{11}{50} = \frac{1}{4} \cdot \frac{4}{17} \cdot \frac{11}{50} = \frac{1}{17} \cdot \frac{11}{50} = \frac{11}{850}[/tex]

A more generic solution:

Let's use the binomials to find the solution with combinations:

We need to pick 3 cards out of 13. This can be done in

[tex]\binom{13}{3} = \frac{13!}{3!\cdot10!}[/tex] ways.

And the total number of ways to pick 3 cards out of 52 is:

[tex]\binom{52}{3} = \frac{52!}{3!\cdot 49!}[/tex]

So the probability is:

[tex]\frac{ \binom{13}{3} }{ \binom{52}{3} } = \frac{ \frac{13!}{3!\cdot 10!} }{ \frac{52!}{3!\cdot 49!} } = \frac{ \frac{13!}{10!} }{ \frac{52!}{49!} } = \frac{13 \cdot 12 \cdot 11}{52 \cdot 51 \cdot 50}[/tex]

Which again brings us to the result computed before.

Answer:

  y = 3x + 2

Step-by-step explanation:

Assuming your table values are (x, y) = (4, 14), (6, 20), (7, 23), the slope and intercept formulas can be used.

  m = (y2 -y1)/(x2 -x1)

  m = (20 -14)/(6 -4) = 6/2 = 3

  b = y -mx

  b = 14 -3(4) = 2 . . . . for (x, y) = (4, 14)

Then the equation of the line is ...

  y = mx + b

  y = 3x + 2

Answer: y = 31

Step-by-step explanation:

y = 3x + 10

y = 3(7) + 10               Plug in the 7 for x, because it shows x = 7 in the question.

y = 21 + 10

y = 31

Answer:

37.3

Step-by-step explanation:

Answer:

37.29

Step-by-step explanation:

Step-by-step explanation:

m<M=m<L=110°

m<N=m<O=x → 2x+2(110°)=360° → x=70°

m<E=180°-22°=158°

m<A=360°-(88°+22°+158°)= 92°

m<D=m<O=61°

m<S=m<G=x → 2x+2(61°)=360° → x=238/2 = 119°

Answer:

Step-by-step explanation:

1)∠L + ∠O = 180       {Co interior angles}

  110 + ∠O = 180

            ∠O = 180 - 110

            ∠O = 70

Base angles of isosceles trapezoid are equal

∠M = ∠L

∠M = 110

∠O = ∠N

∠N = 70

2) ∠c + ∠A = 180               {Co interior angles}

   88 + ∠A = 180

            ∠A = 180 -88

            ∠A = 92

∠D + ∠E = 180       {Co interior angles}

22 +∠E = 180

      ∠E = 180 - 22

      ∠E = 158

3)  ∠O + ∠G =  180           {Co interior angles}

   61 + ∠G = 180

         ∠G = 180 - 61

         ∠G = 119

Base angles of isosceles trapezoid are equal

∠D = ∠O

∠D = 61

∠S = ∠G

∠S = 119

Answer:

Step-by-step explanation:

a+b=-5

a=-5-b, we are also given

ab=-14, using a found above makes this become

(-5-b)b=-14

-5b-b^2=-14

b^2+5b-14=0

(b+7)(b-2)=0

So the numbers are -7 and 2.

Answer:

[tex]q\geq -81[/tex]

Step-by-step explanation:

First, begin by multiplying [tex]\frac{q}{27} \\[/tex] by its reciprocal.

To do this, flip the fraction upside-down.

The resulting equation looks like this: [tex]\frac{27}{1} *\frac{q}{27}[/tex]

Cancel out the two 27's and you are left with [tex]\frac{q}{1}[/tex] , which you can simplify to q.

Next, multiply -3 by [tex]\frac{27}{1}[/tex] . Remember, what you do on one side, you must do on the other.

Your equation should look like this:

[tex]q\geq -81[/tex]

The final answer is [tex]q\geq -81[/tex] .

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the above is really helpful if you don't have a brain.  :P

for 7 we only need Pythagoras's theorem, know it?

[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]

out of curiosity.. does the above formula seem "impossible" ?  or does it make sense?

[tex]c^{2}[/tex] = [tex]12^{2}[/tex] + [tex]16^{2}[/tex]

[tex]c^{2}[/tex] = 144 + 256

[tex]c^{2}[/tex] = 400

c = [tex]\sqrt{400}[/tex]

c = 20

x= 20

for 8 we do need the above list of trig functions. we want to find the Hyp x and we know an angle and the adjacent side sooo use Cos .. b/c we can see it's got those parts in it

Cos(60) = 18 / x

I'll show you the algebra we need to use to get this formula so that we can find x

A = B / x  ( this is how it looks above )

x = B / A    , now just put in the parts

x = 18 / Cos(60)  now solve it w/ your calculator..  :P Cos(60) happens to be 1/2 so you could have done this w/o your calculator   :/

x = 36

there you go,   :)

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete as the polygon A (and other possible polygons to select from) are not given. So, I will answer on a general term.

Assume that Polygon A is a rectangle of dimension 2ft by 5ft.

[tex]Length = 2ft[/tex]       [tex]Width = 5ft[/tex]

Possible scaled copies can be gotten by multiplying the dimension of A by the same scale factor.

Take for instance, the scale factor k is:

[tex]k = 3[/tex]

A scaled copy of polygon A (say polygon B) is: 6ft by 15ft

This is gotten by:

[tex]Length = 2ft * 3 = 6ft[/tex]     [tex]Width = 5ft * 3 = 15ft[/tex]

The area of A is:

[tex]Area = 2ft * 5ft = 10ft^2[/tex]

The area of B is:

[tex]Area = 6ft * 15ft = 90ft^2[/tex]

See attachment for polygons

Comparison

The area of B is greater than the area of B.

This method can be applied to scale factors

Answer:

Perimeter: 32

X = 5

Step-by-step explanation:

If you draw a line to make the triangle the longer leg is equal to 4 then the shorter leg is 3 since your subtracting 13 - 10 to get 3 for the shorter leg. you use Pythagorean theorem that would equal 3^2 + 4^2 = 25 if you take the square root of 25 its 5. So now you know x = 5. Then add all the sides together to get the perimeter.
