Find the circumference of a circle with an area of 1809.56 square centimeters

Answer:

12.79%

Step-by-step explanation:

Let :

Great grand mother = 86 years

Jenny = 11 years

Let the percentage = x

x % of great grandmother's age = Jenny's age

x% * 86 = 11

x/ 100 * 86 = 11

86x / 100 = 11

86x = 100 * 11

86x = 1100

x = 1100/86

x = 12.79

x = 12.79%

Answer:

x = 20°

Step-by-step explanation:

Consecutive angles of a parallelogram are supplementary.

Answer:

  9, the sum of the numbers given in the ratio

Step-by-step explanation:

The reduced ratio 2 : 7 means that two parts correspond to one length and 7 parts correspond to the other length. That is, there are a total of 2+7 = 9 parts in the full length of the segment.

It is convenient to think of the line segment as being divided into 9 equal parts.

Additional comments

It is often helpful to consider the total number of "ratio units" in a given ratio. For example, in this problem, the shorter segment is 2/9 of the whole, and the longer one is 7/9 of the whole.

It can also be useful to consider what a "ratio unit" represents. If the whole segment is 27 inches long, then each of the 9 ratio units will represent 3 inches, for example. This means the division 2:7 is 2(3 in):7(3 in) = 6 in : 21 in.

Answer:

∠G

Step-by-step explanation:

The tangent of an angle is given by the following trigonometric ratio;

[tex]tan\angle X = \dfrac{Opposite \ leg \ length}{Adjacent \ leg \ length}[/tex]

From the question, we have;

tan ∠K = 6/8

ΔGIH is similar to ΔKJL

By observation of the length, we have;

Segment HI and segment JL are corresponding segments

Segment KL and segment HG are corresponding segments

∴ ∠K and ∠G are corresponding angles

∴ tan∠G = tan∠K = 6/8

The angle whose tangent is 6/8 is ∠G

Step-by-step explanation:

Let's draw the rectangle approximately on an x y plane. That would help us to find the length and width of the rectangle.

Answer: 4,480yd^2

Step-by-step explanation:

You have the x and y coordinates of the vertices (10, 10), (10,90), (70.5,90),  and (70.5, 10) you have the coordinates: x and y as the first two which are the ones in bold. From that you do 70.5-10= 60.5.

Then you subtract the x and y coordinates again, which are underlined. From that do 90-10=80

Last you do 60.5x80=4,840 yards squared

Answer:

Step-by-step explanation:

-x-3=y, therefore x = -y-3

-3x - 8y = 4

Find the value of y

Substitute the x in -3x - 8y = 4 with -y-3

We get

-3·(-y-3) - 8y = 4

3y + 9 - 8y = 4

-5y = 4-9

-5y = -5

Ok Here:

Step-by-step explanation:

STEP BY STEP

Substitution:

-x-3=y

-3x-8y=4

Solve for X                Substitute for Y

-3x-8(-x-3)=4                     -(-4)-3=y

-3x+8x+24=4                        4-3=y

5x+24=4                                y=1

    -24

Answer:

[tex]M_{1}[/tex] = [tex]\frac{F_{g}r^{2} }{GM_{2} }[/tex]

Step-by-step explanation:

From Newton's law of universal gravitation, the force of attraction between two objects of masses [tex]M_{1}[/tex] and [tex]M_{2}[/tex] is given as:

[tex]F_{g}[/tex] = [tex]\frac{GM_{1} M_{2} }{r^{2} }[/tex]

Thus, cross multiply to have;

[tex]F_{g}[/tex][tex]r^{2}[/tex] = G[tex]M_{1}[/tex][tex]M_{2}[/tex]

then divide through by G[tex]M_{2}[/tex] to have,

[tex]M_{1}[/tex] = [tex]\frac{F_{g}r^{2} }{GM_{2} }[/tex]

Therefore, [tex]M_{1}[/tex] can be expressed in terms of [tex]F_{g}[/tex], [tex]r^{2}[/tex], G, [tex]M_{2}[/tex] as [tex]\frac{F_{g}r^{2} }{GM_{2} }[/tex]

Answer:

A : 25

Step-by-step explanation:

In a neutral atom, the number of electrons is equal to the number of protons. The atomic number indicates the number of protons.

The mass number is the sum of the number of neutrons and the number of protons.

mass number=protons+neutrons

As we know from the atomic number, the number of neutrons is 14 and the number of electrons is 11.

mass number = 14 + 11

Answer:

choice 1) 2x + 40 = 180

Step-by-step explanation:

(x + 10) + (x + 30) = 180

2x+ 40 = 180

Answer:

X+30+x+10=180

combine like terms

2x+40=180

subtract 40 from both sides

2x=140

divide by 2

x=70

but for you it is 2x+40=180

Answer:

They will both blink again at 3:12 pm.

Step-by-step explanation:

As indicated by the question, the way to solve is to find the Lowest (or Least) Common Multiple of both numbers.

As such:

[tex]\text{List the factors of 12 and 44:}\\12=2*2*3\\44=2*2*11\\\\\text{Take the common factors only once and multiply them by the non-common factors:}\\2*2*3*11=132 \text{ (LCM)}[/tex]

Now knowing the LCM is 132, we convert those minutes into hours and minutes:

[tex]\frac{132}{60}=2\frac{12}{60} \text{ (2 hours and 12 minutes)}[/tex]

Add this to the original time:

[tex]1:00\text{ pm } + \text{ }2:12 \text{ }= \text{ }3:12\text{ pm}[/tex]

Answer:

p(e)=e-3

Step-by-step explanation:

De acuerdo a la información proporcionada, sabes que Paul tenía una determinada cantidad e y al comprar el libro recibió 3 de vuelto, lo que significa que el precio del libro sería igual a restar 3 de la cantidad que tenía al inicio, lo cual se puede expresar de la siguiente forma:

p(e)=e-3, donde

p es el precio del libro

e es la cantidad que Paul tenía al inicio

Answer:

(5,6)

Step-by-step explanation:

Generally, is the coordinate (x,y) is translated right by a units and up by b units, the resulting coordinate wil be;

g(X, Y)  = (x+a, y+b)

To the right is along the positive x axis while up is along the positive y axis

Given a = 3 and b = 4

g(X,Y) = (2 + 3, 2 + 4)

g(X, Y) = (5, 6)

Hence the resulting coordinate of g is (5,6)
