which type of rigid transformation is the equivalent of two reflections across intersecting lines?
a. glide reflection
b. rotation
c. reflection
d. none of these
Answer:
a
Step-by-step explanation:
The equivalent of two reflections across intersecting lines is a glide reflection.
A glide reflection is a combination of a translation and a reflection. It involves moving an object along a line, and then reflecting the object across the same line. Since a reflection is an isometry (a transformation that preserves the distance between points), a glide reflection is also an isometry.
In contrast, a rotation is a transformation that involves turning an object around a fixed point, and a reflection is a transformation that involves flipping an object across a mirror line. Neither of these transformations is equivalent to two reflections across intersecting lines.
Therefore, the correct answer is (a) glide reflection.

The largest taco contained approximately 1 kg of onion for every 6. 6 kg grilled teak. then Amount of grilled steak used: 6.6 (79.17) = 538.356 kg
What is a unit amount in math?
When a price is expressed as a quantity of 1, such as $25 per ticket or $0.89 per can, it is called a unit price. If you have a non-unit price, such as $5.50 for 5 pounds of potatoes, and want to find the unit price, divide the terms of the ratio
1 k + 6.6 k = 617.3
Where “k” is a constant value, a multiplier.
Solving for k:
7.8 k = 617.3
k = 617.3 /7.8
k= 79.17
So:
Amount of onion used:

2x(x+4)+7=(x+8)+2x(x+1)+122x(x+4)+7=(x+8)+2x(x+1)+12
Answer:
x = (-10 + sqrt(180)) / 8
= -1.25 + 0.75 * sqrt(5)
x = (-10 - sqrt(180)) / 8
= -1.25 - 0.75 * sqrt(5)
Step-by-step explanation:
To solve the given equation, we need to combine like terms and isolate the variable on one side of the equation. The given equation is:
2x(x+4)+7=(x+8)+2x(x+1)+12
We can start by expanding the parentheses on the left-hand side to obtain:
2x^2 + 8x + 7 = x + 8 + 2x^2 + 2x + 12
We can then combine like terms on both sides of the equation to get:
4x^2 + 10x - 5 = 0
To solve for x, we can use the quadratic formula, which states that the solutions of the equation ax^2 + bx + c = 0 are given by:
x = (-b +/- sqrt(b^2 - 4ac)) / 2a
In the given equation, we have a = 4, b = 10, and c = -5, so the solutions are:
x = (-10 +/- sqrt(10^2 - 4 * 4 * (-5))) / 2 * 4
= (-10 +/- sqrt(100 + 80)) / 8
= (-10 +/- sqrt(180)) / 8
This gives us two solutions:
x = (-10 + sqrt(180)) / 8
= -1.25 + 0.75 * sqrt(5)
x = (-10 - sqrt(180)) / 8
= -1.25 - 0.75 * sqrt(5)
These are the two solutions of the given equation. Note that we could also write the solutions in a simplified form by factoring the quadratic and using the zero product property, but the quadratic formula is generally more reliable and easier to use.

Answer:
Mabel will pay $91.53 for the television.
Step-by-step explanation:
To calculate the total cost of the television including sales tax, we first need to calculate the amount of sales tax by multiplying the price of the television by the sales tax rate. This gives us $84.75 * 0.08 = $6.78 in sales tax.
To find the total cost of the television, we add the price of the television to the sales tax amount. This gives us $84.75 + $6.78 = $91.53.
Therefore, Mabel will pay $91.53 for the television.

a) The equation is: y = 2x + 3. b) The equations are :Point - slope form: y - 5 = -(x - 1).Slope - intercept form: y = -x + 6. c) The systems are consistent independent. d) The point of intersection is (1, 5).
Linear function
A linear function is defined in slope-intercept formula by the rule presented as follows:
y = mx + b.
In which:
m is the constant rate of change of the function, called slope.
b is the value of y when x = 0, called intercept.
For Sidewalk 1, it is found that:
When x increases by 2, y increases by 4, hence the slope is of m = 2.
When x = 0, y = 3, hence the intercept is of b = 3.
Then the rule is:
y = 2x + 3.
For Sidewalk 2, when x changes by 2, y decays by 2, hence the slope is:
m = -2/2 = -1.
The line goes through point (1,5), hence the equation in point-slope form is:
y - 5 = -(x - 1).
Combining the like terms, the slope-intercept form is:
y - 5 = -x + 1
y = -x + 6.
Since the two lines have different slopes, the system is consistent independent.
The x-coordinate of the intersection is:
-x + 6 = 3 + 2x.
3x = 3
x = 1.
The y-coordinate is:
-x + 6 = -1 + 6 = 5.
Hence the intersection point is:
(1, 5).

f the toss of a coin comes down heads, you win two dollars. if it comes down tails, you lose fifty cents. how much would you expect to gain after 21 tosses (in $ dollars)? $ .
In each toss, the expected value is the probability of winning multiplied by the amount won, minus the probability of losing multiplied by the amount lost. The probability of winning is 1/2, or 0.5, and the probability of losing is also 1/2, or 0.5. The amount won is $2, and the amount lost is $0.50. So the expected value of each toss is 0.5 * $2 - 0.5 * $0.50 = $0.75.
Therefore, after 21 tosses, you would expect to gain an amount equal to 21 * $0.75 = $<<21*0.75=15.75>>15.75.

To find the area of the circle, we first need to find the radius. The radius is half the diameter, so the radius of the circle is 20/2 = 10 feet.
Plugging this value into the formula, we get:
area = 3.14 * 10^2 = 3.14 * 100 = 314 square feet
So the area of the circle is 314 square feet.
Answer:
100π, or about 312. Could also be 314.16 if it needs to be rounded.
Step-by-step explanation:
First, the area of a circle is πr^2
To find radius, it's diameter/2.
So the radius is 20/2 which is 10.
With this, we plug it in: π(10)^2 = π100 = 100π.
That is an exact answer. For a rounded answer, assume π = 3.14.
3.14*100 = 314 sqr feet.
However, it you want to round the final answer, 100π is around 314.159265359 thus making rounding to the nearest hundredth 314.16.
The velocity v of an object dropped from a tall building is given by the formula v = √64d where d is the distance the object has dropped. Solve the formula for d.
The solution for d in the equation v = √64d is d = v²/64
How to determine the solution for d in the equation?From the question, we have the following parameters that can be used in our computation:
v = √64d
Take the square root of both sides
So, we have the following representation
v² = 64d
Divide both sides of the equation by 64
So, we have the following representation
v²/64 = d
Rewrite as
d = v²/64
Hence, the value of d is d = v²/64
