You have a $100 game card at Dave & Buster's. You know you want to play 2 rounds of ski-ball that costs $2 each and you also know you want to play Dance Dance Revolution three times which costs $2.50 each game. You will spend the remaining money on air hockey, which costs $1.75 per game. What's the maximum number of air hockey games you can play?
The maximum number of air hockey games that can be played out of the $100 game card at Dave & Buster's is 50.
How to find the maximum number of times to play the last game?With a $100 game card, the maximum amount of times to play air hockey is found thus;
After 2 rounds of ski-ball at the cost of $2 per game = $4
After 3 rounds of Dance Dance Revolution at the cost of $2.50 per game = $7.50
If air hockey costs $1.75 per game, then;
$4 + $7.50 = $11.50
$100 - $11.50 = $88.50
Therefore $88.50/$1.75 = 50.5 approximately 50 times.
It will take 50 times to use up the rest of the $88.50 left from the $100 game card if air hockey costs $1.75.

Which transformation is similar but not congruent to the original figure?A.dilationB.rotationC.reflectionD.translation
Dilation and rotation is a series of transformations that would produce a figure that is similar to the original figure but not congruent with it.
Transformation of dilation and rotation:
Rigid transformations, such as rotations, reflections, and translations, do not alter the size or shape of a figure; rather, they only move it. The congruence is preserved by these hard changes.
However, because dilation alters a shape's size, they are not hard transformations. The ratio of matching sides would be equal to the scale factor used in the dilatation; the form would remain the same, just the size would vary. This would provide us with a comparable but in congruent value.

What is the solution to the system of linear equations x 3y =- 2?
The solution to the system of linear equations x 3y =- 2 is (x, y) = (6, -2).
The solution to the system of linear equations x 3y =- 2 can be found by using a method such as substitution or elimination.
One possible method is substitution, where we solve one equation for one variable in terms of the other, and then substitute that expression into the other equation.
For example, we can solve the equation x + 3y = -2 for x in terms of y: x = -3y - 2. Then we can substitute this expression into the second equation: -3y - 2 + 3y = -2, which simplifies to y = -2.
Then we can substitute this value back into the first equation to find x: x = -3(-2) - 2 = 6.
So the solution to the system of linear equations x 3y =- 2 is (x, y) = (6, -2).
In conclusion, The system of linear equations x + 3y = -2 can be solved by using the method of substitution. By solving one equation for one variable in terms of the other, and substituting that expression into the other equation, we find that the solution to the system is (x, y) = (6, -2).

What is a 1/3 scale factor?
A 1/3 scale factor is a constant of dilation that is used to change the size of a figure by a factor of 1/3. A dilation is a transformation that changes the size of a figure while preserving its shape.
In a dilation, the scale factor is multiplied by the coordinates of each point on the figure to determine the new coordinates of the dilated figure. If the scale factor is 1/3, then the coordinates of each point on the figure will be multiplied by 1/3, meaning that each point on the figure will be moved one-third as far from the origin as it was before the dilation.
The result of this is that the dilated figure will be smaller than the original figure and will have a scale factor of 1/3. It's important to note that if the scale factor is less than 1, the dilation will reduce the size of the figure and if the scale factor is greater than 1, the dilation will increase the size of the figure.

approximate populations listed above to solve.
There are about 4 thousand fourth graders in Washington, D.C. How many times more fourth graders are
there in the United States than in Washington, D.C.?
There are about 1,000 times as many fourth graders in the US as there are in Washington DC.
what is an algebraic expression ?
Algebraic expression can be defined as the combination of constants , variables and operators.
We write 4 thousand as 4,000
We write 40 thousand as 40,000
We write 400 thousand as 400,000
The value of each place is ten times the value of the place immediately to the right.
So:
40,000 is 10 times 4,000
400,000 is 10 times 40,000.
4,000,000 is 10 times 400,000.
Thus, 400,000 = 10 *40,000, and there are about 10 times as many fourth graders in Texas as there are in Mississippi.
Also, 4,000,000 = 10* 400,000, and there are about 10 times as many fourth graders in the US as there are in Texas.
Finally, to go from 4,000 to 4,000,000, we have to multiply by 10 three times. We see that
10*10*10 = 10 * 100 = 1000
Hence, there are about 1,000 times as many fourth graders in the US as there are in Washington DC.

What are the properties of a rectangle?The following are the qualities of a rectangle:
A quadrilateral with four equal internal angles is known as a rectangle.A rectangle's opposite sides are equal and parallel to one other.A rectangle's inner angle at each vertex is 90°.The sum of a rectangle's internal angles equals 360°.The diagonals cut each other in half.The diagonals are all the same length.The Pythagorean theorem may be used to calculate the length of the diagonals. (a2 + b2) is the length of the diagonal with sides a and b.A rectangle is sometimes known as a parallelogram because its sides are parallel.Parallelograms are all rectangles, but rectangles are not all parallelograms.1) Since the diagonals cut one other in half, it means that ΔCEB, ΔAED are congruent isosceles triangles. It also means that ΔAEB and ΔDEC are congruent isosceles triangles.
This means that ∠BCE = ∠CEB
Where ∠AEB = 98°
∠ABE = (180-98)/2
= 41°
Thus, m∠1 = 90- 41°
m∠1= 49°
2 and 3) Given that ΔAEB and ΔDEC are congruent isosceles triangles, and ∠AEB and ∠DEC are opposite angles (which are congruent), that means
∠AEB and ∠DEC = 98°
Thus,
m∠2 and m∠3 = (180-98)/2 that is
m∠2 and m∠3 = 41° respectively.
4) ∠ADC = 90° (Property of a rectangle)
5) Given an angle and the hypotenuse, we can find AB. Using the law of sines that is:
AB = AC * Sin ∠DAC
Note that ∠DAC ≅ ∠1
Note that AC = 10 (properties of a Rectangle)
Thus
AB = 10 * Sin 49°
AB = 10 * 0.75470958022
AB = 7.5470958022
