The type of transformation that is equivalent to 2 reflections across intersecting lines is rotation
Which transformation is equivalent to a double reflection over parallel lines?A slide or a shift is a translation. By executing two composite reflections along parallel lines, translations may be produced. Translations maintain orientation and are isometric.
Which type of isometry is the equivalent of two reflections in parallel lines?An isometry is made up of two other isometries. The translation is equal to the combination of two reflections over two parallel lines.

Find C. Round to the nearest tenth: 18ft, 20ft, and 22ft
The value of C to the nearest tenth, is 70.5.
What is the Law of Cosines?A planar triangle's side's square is equal to the sum of the squares of the other sides minus the product of those sides and the cosine of the angle between them, divided by two.
We have the triangle ABC.
Where c = 22ft, a = 18ft and b = 20ft
Law of Cosines:
c² = a² + b² - 2ab cosC
Substituting the value of a, b and c to the above equation.
22² = 18² + 20² - 2(18)(20) x cosC
484 = 724 - 720 x cosC
Rearranging
-240 = -720 x cosC
Divide both sides by
-7200.3333333333 = cosC
To find the value of C:
C = Arc cos 0.3333333333

Step-by-step explanation:
What is the equation of the line which passes thru 1/3 and 2 5?
y = 3x – 2 is the equation of the line which passes through 1/3 and 2 5 with slope.
We can use the slope-intercept form of the equation of a line, which is y = mx + b, where m is the slope and b is the y-intercept. We know one point on the line, which is (1/3, 2.5). We can calculate the slope by calculating the rise (change in y) divided by the run (change in x), which is (2.5 - 0) / (1/3 - 0) = 2.5 / 0.33 = 7.5. Therefore, the equation of the line is y = 7.5x + b. To solve for b, we can substitute in our point, (1/3, 2.5) into the equation. We get 2.5 = 7.5(1/3) + b, or 2.5 = 2.5 + b. Therefore, b = 0, and the equation of the line is y = 7.5x + 0, or y = 7.5x.

in the u.s., 95% of children have received their dtap vaccine. calculate the probability that fewer than 700 out of a sample of children received their dtap vaccine.
1.46% probability that fewer than 700 children received their vaccine.
What is probability?
The proportion of favorable cases to all possible cases is used to determine how likely an event is to occur.
Here, we have
95% of children have received their DTaP vaccine p = 0.95
Sample of 750, n = 750
For the approximation, the mean and the standard deviation are given by:
u = np = 750×0.95 = 712.5
σ = [tex]\sqrt{np(1-p)}[/tex]
σ = [tex]\sqrt{750(0.95)(0.05)}[/tex]
σ = 5.97
Using continuity correction, the probability that fewer than 700 children received their vaccine is P(X < 700 - 0.5) = P(X < 699.5), which is the p-value of Z when X = 669.5.
Z = X-u/σ
Z = 669.5 - 712.5/5.97
Z = - 2.18
The p-value of Z = - 2.18 is 0.0146.
Hence, 1.46% probability that fewer than 700 children received their vaccine.

The theorem that proves that the triangles are congruent is the Side-Side-Side (SSS) Congruence Theorem.
The Side-Side-Side (SSS) Congruence Theorem states that if three sides of one triangle are congruent to three sides of another triangle, then the two triangles are congruent. This theorem is useful for proving that two triangles are congruent without having to use angles. The SSS Congruence Theorem is a useful tool for solving geometry problems involving triangles. It can be used to find the unknown side length of a triangle given the lengths of the other two sides, or in more complicated proofs involving multiple triangles. This theorem is also helpful in determining the area of a triangle, as the area is proportional to the product of the lengths of the sides.

The correct equations are 2x +3y=100 and x+y=48. These equations can be used to find the number of multiple-choice and free response questions on the test. The first equation, 2x +3y=100, shows that the total number of points for the multiple-choice questions (2x) plus the total number of points for the free response questions (3y) equals 100. The second equation, x+y=48, shows that the total number of multiple-choice and free response questions on the test is equal to 48. These equations can be solved simultaneously to find the values of x and y.

The linear function that represents the graph of that has the points on the table is: A. .f(x) = 32(3x - 1).
What are the Points of a Linear Function Graph?If a point is on a graph of a linear function, its coordinates will make the equation of the linear function true, if plugged into the equation.
Given the table that represents some of the points that are on a linear function graph, use one point, (1, 64), to check which of the functions represents the table.
Substitute x = 1 and .f(x) = 64 into each of the functions given to see which is true:
.f(x) = 32(3x - 1)
64 = 32(3(1) - 1)
64 = 32(3 - 1)
64 = 32(2)
64 = 64 [true]
.f(x) = -32(x - 3)
64 = -32(1 - 3)
64 = 64 [true], however, if we use another set of values, say (5, 448), this function will not be true.
.f(x) = -2(32x - 3)
6 = -2(32(1) - 3)
6 = -2(29)
64 = -58 [not true]
.f(x) = 16(2x - 1)
64 = 16(2(1) - 1)
64 = 16(1)
64 = 16 [not true]
Therefore, the function that represents the table is: A. .f(x) = 32(3x - 1).

your driveway which is 30 ft wide by 50 ft long needs to be repaved by pouring 3 inch thick layer of concrete. how much it would cost to buy the concrete if one cubic yard of concrete costs $ 130.00?
It would cost $1804.86 to buy concrete for repavement of the driveway if 1 cubic yard of concrete costs $130 .
Given,
Width of driveway = 30 ft = [tex]\frac{30}{3}[/tex] = 10 yard
Length of driveway = 50ft = [tex]\frac{50}{3}[/tex] = 16.667 yard
As the driveway is repaved by pouring concrete then it's height will increase
Height of driveway = 3 inch = [tex]\frac{3}{36}[/tex] = 0.0833 yard
Volume of driveway = length x breadth x height
Volume of driveway = 10 x 16.667 x 0.0833
Volume of driveway = 13.8836 cubic yard
Cost of 1 cubic yard of concrete = $130.00
then cost of 13.8836 cubic yards of concrete will be
130.00 x 13.8836 = $1804.86

What is the meaning of natural numbers are closed under addition?
Its means that the addition of natural numbers obeys the closure property.
In mathematics, the closure property is a property that states that if a set is combined with all its limit points, then the combined set is also a limit point. The closure property applies to sets of real numbers, vectors, and matrices. It states that the closure of a set is itself, i.e., the set is closed under the given operation. The phrase "closed under addition" means that when two natural numbers are added together, the result is also a natural number. In other words, natural numbers are part of a closed system concerning addition; the addition operation always produces another natural number.

−2x+5y=−2

Solution:
After solving the system of equation we will get
x = 5y/2 +1
y = 2/5- 2x/5
First equation is written
−2x+5y=−2
Subtract 5y from both sides.
−2x =−2−5y
The equation is in standard form.
−2x=−5y−2
Divide both sides by −2.
-2x/-2 = -5y-2/ -2
Dividing by −2 undoes the multiplication by −2.
x= −5y-2/-2
Divide −2−5y by −2.
so
x= 5y/2 + 1
Now the second equation is
4x−10y=4
Add 4x to both sides
-10y = 4-4x
The equation is in standard form.
Divide both sides by 10
-10y/10= 4-4x/10
Dividing by 10 undoes the multiplication by 10.
y= 4-4x/10
Divide 4-4x by 10.

Let A be the event of getting head on the first throw and B and C be events of getting tails on the second and third throws of dice respectively.
P(A) = P(B) = P(C) = 1/2
