A store sold 550 video games during the month of December. If this made up 12.5% of its yearly video games scales, about how many video games did the store sell all year?
Answer:
The store sold 4,400 video games all year.
Step-by-step explanation:
Percentages
The x percent of a number N is calculated as:
[tex]\displaystyle P=\frac{x}{100}*N[/tex]
If the value of P is known, then:
[tex]\displaystyle N=\frac{100}{x}*P[/tex]
We know the store sold P=550 video games during the month of December and it corresponds to the x=12% of its yearly games sales (N).
Let's calculate N:
[tex]\displaystyle N=\frac{100}{12.5}*550[/tex]
N = 4,400
The store sold 4,400 video games all year.

The top of a rectangular table has an area of 21 square feet. The width of the table is 3 1/2 feet. What is the length of the table
As per given data area of the top of the rectangular table 21 square feet ,
width [tex]3\frac{1}{2}[/tex] feet the length of the table is equal to 6 feet.
As given,
Area of the top of the rectangular table = 21square feet
Width of the table = [tex]3\frac{1}{2}[/tex] feet
Let 'l' be the length of the rectangular table
Area = length × width
⇒ 21 =(7/2) × l
⇒l =(21 ×2)/7
⇒l=6feet
Therefore, as per given data area of the top of the rectangular table 21 square feet , width [tex]3\frac{1}{2}[/tex] feet the length of the table is equal to 6 feet.

Which function is graphed?
Answer:
Option A
Step-by-step explanation:
The given piecewise function shows that there is a jump discontinuity at x=1 in the first part of the piecewise function. Hence, this means that for the first part of the piecewise function, x=1 isn't included, but in the second part of the piecewise function, it is.
We can therefore eliminate C and D.
Looking at the first part of the piecewise function, we can see as x grows smaller, y grows larger. Therefore, A is the more preferred answer because the domain x<1 is valid.

What is defined as the linear equation in two variables?Linear equations in two variables are equations with one, even no, or infinitely many solutions in which each of a two variables has the highest exponent order of 1. A two-variable linear equation has the standard form ax + by + c = 0, where x and y are the variables.Let 'x' be the number of large frames.
Let 'y' be the number of small frames.
The concepts used is;
money + money = money and
number of small frames + number of large frames = total number of frames.
Cost of each small frame is $7.
The cost of each large frame is $18.
Total cost is $153.
The system of equations are formed as;
$18y + $7x = $153 ........equation 1.
x + y = 14
y = 14 - x .....Put this in equation 1.
$18y + $7x = $153
18(14 - x) + 7x = $153
252 - 18x + 7x = 153
11x = 99
x = 9
y = 14 - 9 = 5
Thus, the number of large frame bought by women are 5 and small frames are 9.

Factor $9p^2 + 30p + 25.$ pls help
Answer:
(3p + 5)^2
Step-by-step explanation:
9p^2 + 30p + 25
9p^2 is the square of 3p = a
25 is the square of 5 = b
This may be the square of a binomial.
We need to check the middle term.
(a + b)^2 = a^2 + 2ab + b^2
2ab = 2(3p)(5) = 30p
This is the square of a binomial.
9p^2 + 30p + 25 = (3p + 5)^2

Which equation matches the function shown below?
Answer:
Step-by-step explanation:
Pick the two easiest points to deal with.
(0,4) and (2,0)
Find m
m = (y2 - y1)/(x2 - x1)
y2 = 4
y1 = 0
x2 =0
x1 = -2
m = (4 - 0)/(0 - - 2)
m = 4/2 = 2
Now use one of the points to find b
y = mx + b Use (0,4)
4 = 2*0 + b
b = 4
The equation you want is y = 2x + 4

Answer:
I‘m pretty sure its a special right triangle, basically a 30, 60, 90 triangle. I checked with the formula and it’s correct. So the angle W is wither a 60 Degree or 30 degree and I‘m on the side of 30 degrees.
So I’m pretty sure its 30 degree.
The formuda is the hypotenuse is 2x and the (a) (3 in this case) is x. The 5 would come out as the formula 3[tex]\sqrt{3}[/tex]. Now we know the sides, 3, 5 and 6 so we just plug it in and solve for the square root and it equals to ABOUT 5.
I’m not sure if I’m correct but I’m not confident.
how you can use Triangle congruence to solve real-world problems? give 3 examples.
Answer:
1.Many pairs of triangles designed into a building, for example as roof ends, would be congruent, so the roof beam and the top edges of the walls are horizontal.
2.The congruent triangle is used in most of the building that are design to stay in bad conditions and Strong winds for Example the Sydney Bridge.
3.in real life two triangles are rarely exactly congruent. However they are crucial in the construction of large man-made structures. This is because a triangle is the most stable shape and the congruence is needed to create even surfaces.

2 What is the GCF of y2(y + 1) and y(y + 2)?
Answer:
the answer is Y
Step-by-step explanation:
The greatest common factor (GCF) of two polynomial expressions is y.
The greatest common factor (GCF) of two polynomial expressions is the polynomial with the largest set of factors that is a factor of both polynomials.
To find the GCF of y2(y + 1) and y(y + 2), we can factor each polynomial:
y2(y + 1) = y(y)(y + 1)
y(y + 2) = y(y + 2)
The only factor that both polynomials have in common is y, so the GCF is y.
Here is the solution in more detail:
Factor each polynomial.
y2(y + 1) = y(y)(y + 1)
y(y + 2) = y(y + 2)
Find the factors that are common to both polynomials.
The only factor that both polynomials have in common is y.
The GCF is the polynomial with the largest set of factors that is a factor of both polynomials.
The GCF is y.
Therefore, the GCF of y2(y + 1) and y(y + 2) is y.

The angle by which turns clockwise about point P to coincide with is

If from point P, a point D is drawn directly opposite point C so that D, P, and C are on the same straight line, the angle by which turns counterclockwise about point P to coincide with is
The angle by which turns counterclockwise about point P to coincide with is 180 degree angle
What is 180 degree angle?
The angle which forms a straight line is called the 180-degree angle. A 180-degree angle is a straight angle and it is exactly half of a revolution. The two arms of the angle which are making 180-degree are just opposite to each other from the common vertex.
The points D, P and C forms a straight line.
So, if it turns clockwise about Point P, it would make an angle of 180 degree.
as the point D and C are of equal lengths and opposite to each other, the angle from P turning clockwise makes 180 degree angle.

Write a system of equations modeling the given conditions. Then solve the system by the substitution method and find the two numbers.
The difference between two numbers is 3. The sum of the larger number and twice the smaller number is 21. Find the numbers.
System of equations:
x - y = 3
x + 2y = 21
solving using substitution:
1. isolate one of the variables in one of the equations
x - y = 3
x = 3 + y
2. substitute 3 + y into the other equation
3 + y + 2y = 21
3. simplify
3 + 3y = 21
3y = 18
y = 6
4. substitute 6 back into one of the equations and solve for x
