One side of a square is 10 units. Which is greater, the number of square units for the area of the square or the number of units for the perimeter? Explain.
Given:
[tex]\text{Side of }\square \ \text{= 10 units}[/tex]
Area of square:
The area of the square can be determined by using the formula "(side)²".
⇒ Area of square = (side)²
⇒ = (10)² [Side = 10 units]
⇒ = (10)(10)
⇒ = 100 units²
Therefore, the area of the square is 100 units².
Perimeter of square:
The perimeter of the square can be found by using the formula "4(side)".
⇒ Perimeter of square = 4(side)
⇒ = 4(10)
⇒ = 4 × 10
⇒ = 40 units
Furthermore, the question says:
Which is greater?
- The number of square units (100) for the area of the square.
- The number of units (40) for the perimeter
Conclusion: Since 100 is greater than 40, the number of square units for the area of the square is greater than the number of units for the perimeter.

Suppose you toss 10 coins randomly at the board below and that all coins stay on the board. Find the probability as a fraction of landing in the shaded region.
A. 1/9
B. 8/9
C. 2/3
Answer: B
Step-by-step explanation:
The area of the larger square is 9^2 = 81, and the area of the smaller square is 3^2 = 9. This means the area of the shaded region is 81-9=72. Hence, the desired probability is 72/81 = 8/9.
Millie makes a placemat with a triangular pattern. Each triangle has a base of 5 inches and a height of 4 inches. Millie sews together a total of 42 triangles.
Each triangle has an area of
inches2
The total area of the placemat is
inches2
Answer:
10 inches²
420 inches²
Step-by-step explanation:
1) Area of a triangular placemat:
= ½ × base × height
= ½ × 5 × 4
= 10 inches²
2) Total area of the placemat:
= Area of a placemat × Number of triangles
= 10 × 42

Using the triangle inequality theorem, the set of lengths that meet all the requirement is: 3, 4, 5, 7.
What is the Triangle Inequality Theorem?The triangle inequality theorem states that the sum of any of the two sides of a triangle must be equal or greater than the third side, i.e. if a, b, and c are sides of a triangle, then:
a + b ≥ cb + c ≥ aa + c ≥ bIf we have the following set of numbers, 3, 4, 5, 7.
Set 3, 4, 5 will give us:
3 + 4 ≥ 54 + 5 ≥ 33 + 4 ≥ 5This means 3, 4, 5 will form a triangle.
Set 4, 5, 7 will give us:
4 + 5 ≥ 75 + 7 ≥ 47 + 4 ≥ 5This means 4, 5, 7 will form a triangle.
Set, 3, 5, 7 will give us:
3 + 5 ≥ 75 + 7 ≥ 37 + 3 ≥ 5This means 3, 5, 7 will form a triangle.
Set 3, 4, 7 will give us:
3 + 4 ≥ 74 + 7 ≥ 37 + 3 ≥ 4This means 3, 4, 7 will form a triangle.
Therefore, we can conclude that the set of lengths, 3, 4, 5, 7, meets all the requirements.

Jack can program an app in 9 hours. Chris can program the same app in 8 hours. How long would it take them to program the same app working together?
The time it will take Jack and Chris to program the app when they work together is 4.24 hours.
What is a rate?Rate is a ratio that compares two different quantities which have different units.
Jack program an app in 9 hours. Therefore, the rate is as follows;
1 / 9
Chris can program the same app in 8 hours. Therefore, the rate is as follows;
1 / 8
When they do it together.
1 / 9 + 1 / 8 = 8 + 9/ 72 = 17 / 72
1 / t = 17 / 72
cross multiply
72 = 17 t
t = 72 / 17
t = 4.23529411765
t = 4.24

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y < 4x − 8
y is greater than or equal to negative 5 over 2 times x plus 5
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area.
Part B: Is the point (5, −8) included in the solution area for the system? Justify your answer mathematically.
< sign so it's dotted line to be graphed .
Put (0,0)
0<0-80>-8Away from origin shading
And
y≥-5/2x+5Put 0
0≥-5/5=-1Rational function ,two side parabola type lines
Dark lines and it's shading from origin in one part and in other towards origin(Look attachment)
Graph attached
Yes (5,8) is included in solution region
Answer:
Given inequalities:
[tex]y < 4x-8[/tex]
[tex]y\geq -\dfrac{5}{2}x+5[/tex]
Part AThe graph of the system is made up of 2 straight line graphs.
The graph of [tex]y < 4x-8[/tex] is a dashed straight line with shading under the line.
The graph of [tex]y\geq -\dfrac{5}{2}x+5[/tex] is a solid straight line with shading above the line.
The solution area is the area where the shading of the two lines overlaps.
Part BTo determine if the point (5, -8) is included in the solution area, input the point into both inequalities:
[tex]\begin{aligned}y & < 4x-8\\\implies -8 & < 4(5)-8\\-8 & < 20-8\\-8 & < 12 \quad \leftarrow \textsf{correct}\end{aligned}[/tex]
[tex]\begin{aligned}y & \geq -\dfrac{5}{2}x+5\\\implies -8 & \geq -\dfrac{5}{2}(5)+5\\\implies -8 & \geq -7.5 \quad \leftarrow \textsf{incorrect}\end{aligned}[/tex]
Therefore, the point (5, -8) is not included in the solution area as it is only true for one inequality.

Use the method of symmetry to find the extreme value of each quadratic function and the value of x for which it occurs.
f(x)=(x-3)(x+8
a) x-intercepts are _________
b) midpoint of the x-intercepts is ___________
c) the extreme value is _______________
d) f(_) = ______________
Answer:
See belowStep-by-step explanation:
The x-intercepts are the points with y- coordinate of 0
(x - 3)(x + 8) = 0x - 3 = 0 or x + 8 = 0x = 3 or x = - 8a) x-intercepts are
3 and - 8b) midpoint of x-intercepts is
(3 - 8)/2 = - 5/2 = - 2.5c) The extheme value has x- coordinate of - 2.5 and y- coordinate
(-2.5 - 3)(- 2.5 + 8) = (-5.5)(5.5) = - 30.25d) f(- 2.5) = - 30.25
Answer:
[tex]\sf a) \quad x = -8 \:\:and \:\:x = 3[/tex]
[tex]\sf b) \quad \left(-\dfrac{5}{2},0\right)[/tex]
[tex]\sf c) \quad \left(-\dfrac{5}{2},-\dfrac{121}{4}\right)[/tex]
[tex]\sf d) \quad f(x)=\left(x+\dfrac{5}{2}\right)^2-\dfrac{121}{4}[/tex]
Step-by-step explanation:
Part (a)
The x-intercepts are the x-values when the curve crosses the x-axis, so when the function is equal to zero:
[tex]\implies f(x)=0[/tex]
[tex]\implies (x-3)(x+8)=0[/tex]
Therefore:
[tex](x-3)=0 \implies x=3[/tex]
[tex](x+8)=0 \implies x=-8[/tex]
Therefore, the x-intercepts are x = -8 and x = 3
Part (b)
[tex]\textsf{Midpoint}=\left(\dfrac{x_2+x_1}{2},\dfrac{y_2+y_1}{2}\right)\quad \textsf{where}\:(x_1,y_1)\:\textsf{and}\:(x_2,y_2)\:\textsf{are the endpoints}}\right)[/tex]
[tex]\sf \implies Midpoint=\left(\dfrac{-8+3}{2},\dfrac{0+0}{2}\right)=\left(-\dfrac{5}{2},0\right)[/tex]
Therefore, the midpoint of the x-intercepts is (-5/2, 0)
Part (c)
The extreme value is the vertex. The vertex is:
the minimum point if the parabola opens upwardsthe maximum point if the parabola open downwardsThe x-coordinate of the vertex is the x-value of the midpoint of the x-intercepts. Therefore, the x-value of the extreme value is x = -5/2.
To find the y-coordinate, substitute this into the given equation:
[tex]\implies \sf y=\left(-\dfrac{5}{2}-3\right)\left(-\dfrac{5}{2}+8\right)=-\dfrac{121}{4}[/tex]
Therefore, the extreme value is:
[tex]\sf \left(-\dfrac{5}{2},-\dfrac{121}{4}\right)[/tex]
Part (d)
The function in vertex form is:
[tex]\sf f(x)=\left(x+\dfrac{5}{2}\right)^2-\dfrac{121}{4}[/tex]
[tex]\begin{aligned}\implies \sf f\left(-\dfrac{5}{2}\right)& = \sf \left(-\dfrac{5}{2}+\dfrac{5}{2}\right)^2-\dfrac{121}{4}\\\\ & = \sf 0 -\dfrac{121}{4}\\\\ & = \sf -\dfrac{121}{4} \end{aligned}[/tex]

What is Line segment?Line segment is a part of the line which have two endpoints and bounded by two distinct end points and contain every point on the line which is between its endpoint.
Given that;
The coordinate are,
⇒ A = (- 5x, 4y)
⇒ B = (- 2x, - 4y)
Now,
Since, We know that;
The distance between the points (x₁ , y₁) and (x₂, y₂) is,
⇒ d = √ (x₂ - x₁)² + (y₂ - y₁)²
So, The distance between the points (- 5x, 4y) and (- 2x, - 4y) is,
⇒ d = √ (- 2x - (- 5x))² + (- 4y - 4y)²
⇒ d = √(3x)² + (- 8y)²
Thus, The values needed to find the length AB is find as;
⇒ AB = √(3x)² + (- 8y)²

What is one-sided limit for function?It should be noted that the limit from one side is simply when the side of the functions is used with respect to the point of interest.
For this graph, the point x = 2 on the left from the point x = 2 lies a ray. The prediction here is that the value of function on x = 2 us the value that the line gives for y.
