3/7 of the students in a school are girls. If there are 64 boys find how many girls there are

The general form is nthroot{a} in index form looks like this: a^(1/n).

Let's rationalize the denominator first.

Doing so, we get (1/2)sqrt{2}.

In index form, the sqrt{2} = 2^(1/2).

We now have (1/2)[2^(1/2)].

Is this clear?

Compare the given equation with the general equation of a circle

Given equation: x² + y² - 8x +6y +9 = 0

Equation of a circle: x² + y² + 2gx + 2fy + c = 0

2g= -8; g = -8÷2= -4

2f = 6; f = 6÷2 = 3

c= 9

Solving for radius of the circle...

r =√g² + f² - c

g= -4, g² = ±16

f = 3, f² = 9

Substituting, we have

r = √16 + 9 - 9

r = √25-9

r=√16

r = 4

Therefore, the centre and radius of the circle is 9 and 4 respectively.

Hope this helped!

Answer:

Im not sure how you are supposed to answer this but they are similar by side angle side

Step-by-step explanation:

We are given that NO/OQ=PO/OM

This tells us that the sides are in a ratio.

We also know that angle NOM is equal to angle POQ

Now we have 2 sides and 1 angle thus they are similar by side angle side

I hope this helps you come up with your statements and reasons

Answer:

La porción de la casa que le corresponde pintar a Alan es [tex]\frac{13}{72}[/tex]

Step-by-step explanation:

Sabes que Alejandro pinta 3/8 de la casa durante el primer día, mientras que Alberto pinta 4/9 de la casa durante el segundo día. Entonces, la porción pintada de la casa durante esos dos días es la suma entre la porción pintada por Alejandro y la porción pintada por Alberto:

[tex]\frac{3}{8} +\frac{4}{9}[/tex]

Un método para sumar fracciones con distinto denominador consiste en buscar el común denominador de las fracciones que se van a sumar. Para ello se multiplica los denominadores de las fracciones: 8*9= 72. El común denominador se divide entre el denominador de la primera fracción.   El resultado de la división se multiplica por el numerador de la misma fracción. Una vez que se divide y se multiplica, el resultado se coloca en el numerador con el signo correspondiente. Se realiza el mismo procedimiento con la otra fracción y se realiza la suma con los numeradores resultantes.

Entonces, en este caso se obtiene:

[tex]\frac{3}{8} +\frac{4}{9}=\frac{27+32}{72} =\frac{59}{72}[/tex]

Entonces, para calcular la porción de la casa que le corresponde pintar a Alan, y considerando que 1 representa un entero, la totalidad de la casa que se desea pintar, se realiza la resta entre la totalidad de la fachada a pintar y la porción pintada por Alejandro y Alberto:

[tex]1-\frac{59}{72}[/tex]

Considerando que el procedimiento de la resta es similar a la suma, se obtiene:

[tex]1-\frac{59}{72}=\frac{72-59}{72} =\frac{13}{72}[/tex]

La porción de la casa que le corresponde pintar a Alan es [tex]\frac{13}{72}[/tex]

Answer:

A(-a,-b)and B(-a,-b) be

distance between AB= square root(x2-x1)^2+(y2-y1)2

AB= square root (-a)-(-a)^2+(-b)-(-b)^2

AB= squareroot (-a+a)^2+(-b+b)^2

AB= square root (0)^2+(0)^2

AB=square root 0+0

AB= square root 0

Answer:

x=3

Step-by-step explanation:

The triangle has angles 30,60,90

In this type of right triangle, the ratio of the sides is 1:square root of 3:2

In this type of triangle, the square root of 3 is equal to the 1 in the ratio above because it is across from the angle 30

With this, we multiply the ratio at the top by the square root of 3

since x is across the angle 60, we multiply square root of 3 by the square root of 3 which equals 3.

I hope this makes sense

Answer: 56.64%

Step-by-step explanation:

Given: Previous amount of flour = 2.26 kilograms

By the end of the baking session, amount of flour = 0.98 kilograms

Decrease in amount = 2.26-0.98 = 1.28  kilograms

Percent decrese = [tex]\dfrac{\text{decrease in amount }}{\text{previous amount}}\times100[/tex]

[tex]=\dfrac{1.28}{2.26}\times100\approx56.64\%[/tex]

Hence, the percent decrease in the amount of flour = 56.64%

Answer:

To do this, you need to find the amount of discount of the original price. To find a percent of a number you first convert the percent to a decimal (i.e. 25% = 0.25). Then you multiply this decimal by the original price. Therefore, the sale price is $17.21. If example.

Answer:

Step-by-step explanation:

First we need to factorize the given area of the rectangle as shown;

Given

A(x) = x^2-10x+16

Factorize

A(x) = x²-8x-2x+16

A(x) = (x²-8x)-(2x+16)

A(x) = x(x-8)-2(x-8)

A(x) = (x-2)(x-8)

Since area of a rectangle = length ×width

Hence the binomial that represents the width of the pool is w(x) = x-2

b) If the width of the deck is 17feet

Width = x-2

17 = x-2

x = 17+2

x = 19feet

Get the length

Length = x-8

Length = 19-8

Length = 11

Get the perimeter

P = 2(L+W)

P = 2(17+11)

P =2(28)

P = 56feet

Perimeter of the deck is 56feet

Answer: Yes, No

Answer:

y=x+3

Step-by-step explanation:

The equation "y=x+3" cannot be written in the form y=kx because the form doesn't use addition as a basic operation. Let's try verifying the choices:

y=x is possible if the value of k is 1, provided that both y and x are of the same value.

y/2=x is possible because y=2x, provided that 2 is the value of k.

y=-1/10x is possible because -1/10 is the value of k. This is just the same with y=kx.

Answer:

x = -4 3/5 or -4.6

Step-by-step explanation:

Subtract 4 from both sides

x = -4 3/5

Answer:

1. angle addition post

2. 2x=56

The corresponding angles of the lines solved and the value of x = 28°

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line. The intersecting line is known as transversal line.

We can conclude three factors determining parallel lines ,

Alternate angles are equal

Corresponding angles are equal

Co-interior angles add up to 180°

Given data ,

Let the measure of ∠ELG = 124°

The measure of ∠ELD = 2x

∠ELG and ∠ELD are a linear pairs of angles

So , the measure of ∠ELG  + ∠ELD = 180°

On simplifying , we get

2x + 124° = 180°

Subtracting 124° on both sides , we get

2x = 56°

Divide by 2 on both sides , we get

x = 28°

Therefore , the value of x is 28°

Hence , the angle is x = 28°
