Answer:

The answer is "393 ft".

Step-by-step explanation:

Please find the complete question in the attachment file.

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:

I am pretty sure the answer is B.

Answer:

B

Step-by-step explanation:

These are confusing, so I understand why it's a little bit of a frustration lol.

The first thing to look for is where the point is placed. This is -1, so make sure it's not on a positive 1.

All of them are using open circles, so this is such an easier way to tell which one to use. If it did have a closed and open circle for the point, remember that the inequality symbols > and < will always have an open circle. (By open I mean it isn't filled in).

The next thing to look for is to look where the line should be going. I can see that you selected D, but you want x to be less than -1, not greater. If the inequality symbol is turned away it means the number/variable is less than whatever it's being compared to, if that makes sense.

It's almost so simple yet so confusing at the same time. Good luck :)

(4y-y)(9+4x+3y)

36y+16xy+12y^2-9y-4xy-3y^2

collect like terms

36y-9y+16xy-4xy+12y^2-3y^2

=27y +12xy+9y^2

Answer:

x=2

Step-by-step explanation:

[tex] log_{10}({10}^{2}) = x \\ 2 log_{10}(10) = x \\ 2 \times 1 = x \\ x = 2[/tex]

because

[tex] log_{10}(10) [/tex]

equals 1

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:

  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:

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:

Step-by-step explanation:

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:

15 cm

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:

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.

Answer: 14 dogs

Step-by-step explanation:

Given

The ratio of cats to dogs is 9:7

The shelter has 18 cats

Suppose shelter has x dogs

[tex]\Rightarrow \dfrac{9}{7}=\dfrac{18}{x}\\\\\Rightarrow x=\dfrac{18\times 7}{9}=14\ \text{dogs}[/tex]

Answer:

Step-by-step explanation:

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:

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
