Answers
Answer:
Una estrella en el cielo está relacionada con un punto de geometría básica.
Un punto es un objeto matemático que tiene una dimensión 0, pero que se puede especificar en un espacio de n dimensiones, utilizando coordenadas 'n'
Una estrella se puede ubicar usando un sistema de coordenadas, y las dimensiones de la estrella no se pueden estimar fácilmente a partir de su apariencia.
B. Un rayo de luz está relacionado con un rayo en geometría básica.
Un rayo en geometría básica, tiene un punto de inicio definido, pero no tiene fin, por lo tanto, un rayo de luz está relacionado con un rayo en geometría básica
C. La superficie del agua en el lago está relacionada con un plano en geometría básica.
La superficie del agua es una superficie coplanar, de manera que las cuatro esquinas y otros puntos existen en el mismo plano (la superficie del agua), lo que equivale al plano, que también tiene 3 o más puntos en el mismo nivel.

Find the solution set of the inequality \qquad52- 3x < -14.52−3x<−14.52, minus, 3, x, is less than, minus, 14, point \qquad xxx
Answers
Answer:
x > 22
Step-by-step explanation:
Given the inequality;
52- 3x < -14
Subtract 52 from both sides
52 - 3x - 52 < -14 - 52
-3x < -14 - 52
-3x < -66
Divide both sides by -3
-3x/-3 < -66/-3
x > 22
Hence the required inequality is x > 22
Plot the coordinates of the point:
(a) whose co-ordinate is -5 and which lies on y axis.
(b) Which lies on x and y-axis both.
(c) whose abscissa is 3 and which lies on x-axis in cartasian plance.
Answers
Answer:
First, a regular point is written as a coordinate pair (x, y).
If the point lies on the x-axis, then we have y = 0
if the point lies on the y-axis, then x = 0
And x is the abscissa, y is the ordinate.
The points will be graphed at the end.
a)
Ordinate = -5, then y = -5
and it ies on the y-axis, then x = 0
So this point is represented by A = (0, -5)
b)
Lies on the y-axis and in the x-axis, then x = 0 and y = 0, so the point is represented by B = (0, 0)
c)
The abscissa is 3, so x = 3, and the point lies on the x-axis, so y = 0
Then this point is represented by C = (3, 0)

Answers
Answer:

Step-by-step explanation:
volume of a hemisphere = (2/3) x (n) x (r^3)
n = 3.14
r = radius = 12/2 = 6
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

Required
The percentage of household with 2 people
First, calculate the total frequency
[tex]Total = 3 + 4 +6+7+5[/tex]
[tex]Total = 25[/tex]
The frequency of household with 2 people is:
[tex]f(2) = 4[/tex]
So, the percentage is calculated as:
[tex]\% =\frac{f(2)}{Total} * 100\%[/tex]
[tex]\% =\frac{4}{25} * 100\%[/tex]
[tex]\% =\frac{400}{25}\%[/tex]

Only one number will make this missing length true.
Obviously it's a square so one number x one number will equal to 36 [tex]in^{2}[/tex]
6 x 6 = 36 [tex]in^{2}[/tex]
Answer:
The missing length of square is 6 in.
Step-by-step explanation:
Here we have given the area of square = 36 in ²
We need to find the missing length of square .
note :- missing length = side all side of square are equal.Using formula
Area of square = ( side ) ²
put the values
36 in² = ( side)²
Finding the square root of 36 in²
√36 in ² = side
6 in = side
Hence, the side of square is 6 in.

To find : Simplify the expression
Solution :
Step 1 - Write the expression
[tex]2 \sqrt{5} (13 + \sqrt{2} )[/tex]
Step 2 - Apply distributive property,
[tex]a(b + c) = a × b + a \times c[/tex]
[tex] = 2 \sqrt{5} \times 13 + 2 \sqrt{5 } \times \sqrt{2} [/tex]
Step 3 - Apply square root property,
[tex] \sqrt{x} \times \sqrt{y} = \sqrt{xy} [/tex]
[tex] = 26 \sqrt{5} + 2 \sqrt{10} [/tex]
or to simplify more substitute the value of [tex] \sqrt{5} = 2.23[/tex] and [tex] \sqrt{10} = 3.16[/tex]

find the time in which a train of length 132 M will cross and electric post if the speed of the train be to 6.4 km /hour
Answers
Answer:
It will take the train 1.2375 minutes to pass the tunnel
Step-by-step explanation:
Mathematically, we know that ;
time = distance/ speed
The distance here is the length of the train which is 132 m ; we can convert this to km by dividing by 1000
We have this as 132/1000 = 0.132 km
So, we have the time as;
0.132 km/6.4 km/hr = 0.020625 hr
Mathematically, we know that 60 minutes make an hour;
so we have
0.020625 * 60 = 1.2375 minutes

Answers
Answer:
Slope of the line, m = 4/3
Step-by-step explanation:
Given;
4x - 1 = 3y + 5
Make y the subject
4x - 1 = 3y + 5
4x - 3y = 5 + 1
4x - 3y = 6
-3y = 6 - 4x
Divide both sides by -3
y = (6 - 4x) / -3
y = -2 + 4/3x
Slope intercept form is given by
y = mx + b

m = slope
y = - 2 + 4/3x
