Determine if the figure below has rotational symmetry, line symmetry or both and
describe the transformation that mas the figure onto itself. BE SPECIFIC. You must
name the center of rotation and degree of rotation if it has rotational symmetry or
lines of reflection if it has line symmetry
Answers
Answer:
A) Given that the figure is a rectangle, it has a rotational symmetry and by rotating the figure 180° about the center of the figure, the preimage and image will coincide
The figure also has a line symmetry for the vertical line x = 5, and a line symmetry for the horizontal line y = 5
Therefore the figure has both symmetry
B) The transformation that maps the figure unto itself are therefore;
1) Rotating the figure 180° about the point (5, 5) which is the center of the figure
2) Reflection of the figure across the line x = 5 and also reflection of the figure across the line y = 5

In a survey of 1046 adults conducted by Bradley Corporation, subjects were asked how often they wash their hands when using a public restroom, and 70% of the respondents said "always."
Identify the sample and the population.
Answers
Answer:
Sample = 1046
Population = All adults.
Step-by-step explanation:
In Statistics, a sample can be defined as a set of items, objects or individuals collected, selected or drawn from a population. Thus, a sample is a subset of a population. In this scenario, the sample is 1046.
On the other hand, population can be defined as the total number of individuals in a survey. Thus, all the adults are a population.
En un colegio hay 315 alumnos de los cuales 1/3 son mujeres y el resto hombres. 2/7 de los hombres juegan al fútbol y el resto al baloncesto. ¿Cuántos hombres juegan al baloncesto?
Answers
Answer:
150 hombres juegan baloncesto.
Step-by-step explanation:
En una escuela hay 315 alumnos de los cuales 1/3 son mujeres y el resto son hombres.
Paso 1
Encontramos el número de estudiantes que son mujeres
= 1/3 × 315
= 105 mujeres.
Se nos dice que el resto son hombres. Por lo tanto, el número de hombres que son estudiantes se da como:
= 315 - 105 mujeres
= 210 hombres
Paso 2
2/7 de los hombres juegan fútbol y el resto baloncesto.
Esto significa que 2/7 de 210 hombres juegan al fútbol
= 2/7 × 210 hombres
= 60 hombres
Por tanto, 60 hombres juegan al fútbol.
Paso 3
También se nos dice que el resto juega al baloncesto.
El número de hombres que juegan baloncesto se calcula como:
210 - 60
= 150 hombres.
Por tanto, 150 hombres juegan baloncesto.
A shop sells pairs of trainers for £52 each. They make a percentage profit of 30% on each pair. What was the cost of each pair of trainers to the shop?i will mark as brainliest if right answer.
Answers
Answer:
£15.6
Step-by-step explanation:
Method 1:
You are trying to find 30% of £52.
Therefore:
[tex]\frac{30}{100} * 52 = \frac{30 * 52}{100}[/tex]
If you solve this you will find that 30 × 52 = 1560, and 1560 ÷ 100 = £15.6.
So, the answer is £15.6.
Method 2:
You can solve 30% of £52 by using an algebra equation.
By using the rule that to convert a percentage to a decimal you divide by 100, you can change 30% to be 0.3.
Now, in order to write the equation, you will have to include 0.3 and 52.
The equation is:
0.3 * 52 = x
Once you multiply, you will find that the answer is £15.6.

The
of a nonvertical line passing through two points is the ratio of the rise to the run.
Answers
Answer: Slope
Step-by-step explanation:
Slope is rise over run. It can be calculated by dividing the change in y (rise) over the change in x (run).
The slope of a non vertical line passing through two points is the ratio of the rise to the run.
What is slope of a line?
The slope of a line is a measurement of its steepness and direction.The slope of a line formula computes the "vertical change" to "horizontal change" ratio between two distinct points along a line.
1. Slope of Parallel Lines :
A set of parallel lines always has the same inclination angle. Assume we possess two parallel lines l1 and l2 in the reference plane, inclined at angles θ1 and θ2 with the x-axis, respectively, such that the, θ2 = θ1.
m1 = m2
Therefore, the slopes of the two given parallel lines are equal.
2. Slope of Perpendicular Lines :
A pair of perpendicular lines always form a 90° angle. Imagine we have two perpendicular lines l2 and l1 in the coordinate plane, inclined at angles θ1 and θ2 with the x-axis, respectively, so that the provided angles follow the external angle theorem, θ2 = θ1 + 90°
m₁ = tan θ₁
m₂ = tan (θ₁ + 90º) = - cot θ₁
m₁ × m₂ = -1
Therefore, the product of slopes of two given perpendicular lines is equal to -1
Hence , The slope of a non vertical line passing through two points is the ratio of the rise to the run.

What is the value of k in the function f(x)=112-kx if f(-3)=121?
Answers
Answer:
k = 3
Step-by-step explanation:
f(x) = 112 - kx ------------------(I)
f(-3) = 121
In equation (I) substitute x = -3
112 - k*(-3) = 121
112 + 3k = 121
3k = 121 - 112
3k = 9
k = 9/3

Find the x-intercept of the line y=-4x +2. Write the point as a coordinate (x,
y).
Answers
Answer:
X intercept = 1/2
(x, y) = (1/2, 0)
Step-by-step explanation:
In order to find the x intercept, plug y = 0
y = - 4x + 2
Plug y = 0
0 = - 4x + 2
4x = 2
x = 2/4
x = 1/2

Two teachers, Mr. Meehan and Mrs. Chipps, decide to buy compasses and rulers for their classrooms. Mrs. Chipps buys 30 compasses and 50 rulers for $95. Mr. Meehan buys 40 of each for $116. What are the individual costs of the compasses and rulers that were purchased? Explanation Please
Answers
Answer:
compass = $ 2.50 each ruler = $ 0.40 eachStep-by-step explanation:
Mrs. Chipps buys 30 c + 50 r = $95
Mr. Meehan buys 40 c + 40 r = $116 x (-1.25) to eliminate r
30 c + 50 r = $ 95
-50 c - 50 r = $-145
-20 c = -50
c = 50 / 20
c = $2.5
substitute c = 2.5 into eq. 1
30 c + 50 r = $95
30 (2.5) + 50 r = 95
75 + 50 r = 95
50 r = 95 - 75
r = 20 / 50
r = 0.40
therefore, the individual costs of the compasses and rulers are:
compass = $ 2.50 each
ruler = $ 0.40 each

The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.
In triangles ΔJMK and ΔLMK, then we have
∠JMK = ∠LMK = 90° (Right angle)
∠JKM = ∠LKM (Given)
KM = KM (Common side)
The triangles ΔJMK and ΔLMK are congruent with each other. Then the sides JK and KL will be equal. Then the value of 'x' will be given as,
KL = JK
11x - 61 = 4x + 9
11x - 4x = 61 + 9
7x = 70
x = 70 / 7
x = 10
The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.
