Four fifths of the children in a school are boys. Five eighths of the girls in the school are right-handed. What fraction of the children in the school are left-handed girls?

Answer:

1

Step-by-step explanation:

if we say (-2,-3) is point 1 and (5,4) is point 2,

then the equation y2-y1/x2-x1 becomes 4-(-3)/5-(-2)

which is 7/7 or 1

Answer:

6 ft

Step-by-step explanation:

6^3 = 216

Answer:

I put B and A= 25

I got it on another website but I'm not entirely sure.

The square is asymmetrical quadrilateral, which implies it has 4 equal sides and angles. This can also be described as a rectangle having two neighboring sides that are both the same length.

It ensures that the elements are perpendicular, either at right angles to one another.

The length of the square pen is [tex]\sqrt{A}[/tex], and the perimeter should be no more than 100  then the perimeter of a square is 4a the over is [tex]a^2[/tex]  So, the equation :

[tex]\to 4\sqrt{A}=100\\\\ \to \sqrt{A}=\frac{100}{4}\\\\\to \sqrt{A}=25[/tex]

Therefore, the final answer is "25".

Unit rate is the quantity of an amount of something at a rate of one of another quantity.

The ratios that have a unit rate greater than 1 are:

9/8 miles : 5/6 hours

4 miles : 3(1/3) hours

7 miles : 3/4 hours

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

9/8 miles : 5/6 hours

4 miles : 3(1/3) hours

7 miles : 3/4 hours

The unit rate of each given ratio.

9/8 miles = 5/6 hours

Multiply 6/5 on both sides.

6/5 x 9/8 miles = 1 hour

54/40 miles = 1 hour

27/20 miles = 1 hour

1.35 miles = 1 hour

4 miles = 3(1/3) hours

4 miles = 10/3 hours

Multiply 3/10 on both sides.

3/10 x 4 miles = 1 hour

6/5 miles = 1 hour

1.2 miles - 1 hour

7 miles = 3/4 hours

Multiply 4/3 on both sides.

4/3 x 7 miles = 1 hour

28/3 miles = 1 hour

9.33 miles = 1 hour

We see that,

All of them have unit rates greater than 1.

Thus,

The ratios that have a unit rate greater than 1 are:

9/8 miles : 5/6 hours

4 miles : 3(1/3) hours

7 miles : 3/4 hours

Answer:

the length of each piece that i got was 3.5 or 3 1/2

Step-by-step explanation:

BC= 12cm

AC = 5cm

According to Pythagoras theorem ,

12^2 + 5^2 = AB^2

144+25 =169 ..

so AB^2 = 169

AB=√169 ..

Therefore, AB= 13cm ..

Answer:

x°=48°

Step-by-step explanation:

angle Y=x°

angle Z= angle y, because equal side of the angles are equal.

so, angle X +angleY+ angle Z=180° ( angle sum property of triangles)

therefore 84°+x°+x°=180°

2x°=180° -84°

2x°=96°

x°=48°

Answer:

R (27, 8)

Step-by-step explanation:

The coordinate plane is a two-dimensional plane consisting of the y axis (vertical line) and x-axis (horizontal line). The origin is known as the zero point (reference point) is the intersection of the x axis and y axis.

A point on the coordinate plane is represented by (x, y) where x is the x coordinate and y the y coordinate.

Given point Q = (18, 5), the x coordinate is 18 and the y coordinate is 5.

Let the location of point R = (a, b)

a = x-coordinate of point Q + 1/2 of x-coordinate of point Q = 18 + (1/2)*18 = 27

b = y-coordinate of point Q + 3 = 5 + 3 = 8

Therefore R = (27, 8)

Answer:

y=2/3x

Step-by-step explanation:

the origin is the point (0,0) and the given slope is 2/3

the equation for slope-intercept form is y=mx+b, where m is the slope and b is the y intercept

the slope is given, meanwhile, the y intercept is the point where the line passes through the y axis, and the x value is 0.

In this question, we actually have the y intercept given, which is (0,0)

we can put it all together then:

y=2/3x+0

or

y=2/3x

60 students 140 adults

Step-by-step explanation:

so 200 into 3 : 7

first we just do this: 200 ÷ (3+7) = 200 ÷ 10 = 20

so a 1 in the ratio is 20 people

and theres 3 : 7

so 3 * 20 = 60

7 * 20 = 140

60 kids to 140 adults

Answer:

140 are students

Step-by-step explanation:

let k = number of kids

set up proportion based on 7 out of 10 are kids

7/10 = k/200

cross-multiply: 10K = 1400

Responder :

Se plantarán 149769 árboles

Explicación paso a paso:

Dado que:

Número de árboles a plantar = 150.000

Los árboles deben disponerse para formar un cuadrado;

La cantidad de árboles que se pueden plantar para hacer el cuadrado más grande posible:

Área de un cuadrado = s²

Dónde; s = Longitud de cualquier lado; ya que todos los lados son iguales.

El mayor número de árboles que se pueden plantar es el cuadrado perfecto más alto hasta 150.000.

Esto se puede obtener tomando la raíz cuadrada de 150000

Cuadrado (150.000)

= 387,29833

El cuadrado del número entero da el valor cuadrado perfecto más alto antes de 150 000

Por lo tanto,

s = 387 =; 387

Cantidad total de árboles; s² = 387² = 149769

Answer: x= 18

Step-by-step explanation:

3x - 16 = 38

38 + 16 = 54

3x/3 = 54/3

X= 18

Step-by-step explanation:

[tex] \tt{3x - 16 = 38}[/tex]

We want to remove the 16 first. So , Since the original equation is - 16 , we are going to use the oppsite operation and add 16 to both sides.

⟶ [tex] \tt{3x - 16 + 16 = 38 + 16}[/tex]

Simplify ! - 16 + 16 = 0 on the left. 38 + 16 = 54 on the right.

⟶ [tex] \tt{3x = 54}[/tex]

Now , we need to think how to remove the coefficient 3. Since the opposite of multiplication is division , we are going to divide both sides by 3.

⟶ [tex] \tt{ \frac{3x}{3} = \frac{54}{3}} [/tex]

Simplify ! 3 / 3 = 1 on the left and 54/3 = 18 on the right . So, our answer is 18.
