8/15
2/5
9/20
1/2
Answer:
B. 2/5
Step-by-step explanation:
First we write down the numbers.
1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20.
Multiplies of three or five above are: 6,9,10,12,15,16,19,20 (there are 8)
So 8/20.
8/20 simplified is 2/5
So, it's B.

Given :△ABC (to the right), AB = 15, BD = 9,
AD ⊥BC m∠C = 30°. Find the perimeter of triangle.
Answer:
48 + 12√3 units
Step-by-step explanation:
ALL LENGTHS MUST BE POSITIVE (I did this to avoid writing ± and showing that only + works)
1. Find AD (you'll find why later): 15² = 9² + AD² --> AD² = 144 --> AD = 12
2. 30-60-90: 12-DC-AC --> AC = 24, DC = 12√3 (side opposite of 90 is double side opposite of 30, side opposite of 60 is √3 times the opposite of 30)
P = AB + BD + DC + AC = 15 + 9 + 12√3 + 24 = 48 + 12√3 units
The perimeter of triangle △ABC is found by summing all sides of the triangle, resulting in 51.
Explanation:In this question, we are dealing with the triangle △ABC. We know that AB = 15, BD = 9, AD is perpendicular to BC, and m∠C = 30°. Remember, the sum of all sides in a triangle constitutes the perimeter.
Given that AB=15 and BD=9, and as BD is the opposite side of m∠C = 30°, we know that the hypotenuse is twice the length of the opposite side in a 30-60-90 triangle. Thus, AD = 2BD = 18. Since AD is also perpendicular to BC, AD divides the triangle into two right triangles.
We know that the side adjacent to ∠C is half the length of the hypotenuse in a 30°-60°-90° triangle. Hence, CD = AD/2 = 18/2 = 9. Now, BC = BD + CD = 9 + 9 = 18. Summing up all sides of the triangle, the perimeter of △ABC = AB + BC + AC = 15 + 18 + 18 = 51.

Only the last two options are true.
The first one is false, because 4.5 is the value of the maximum of f(x), not the point where it is reached.
The second one is false, because g(x) has a maximum of 9, so it is a downward-facing parabola (just like f(x)), so it doesn't have a minimum.
The third one is true, because the maximum value of f(x) is 4.5, and the maximum value of g(x) is 9, which is twice the maximum of f(x)
The last one is false (see point 2).
Answer:
The third and last one.
Step-by-step explanation:
First, by looking at the graph you can tell that the parabola peaks where x = 0.5, not 4.5, so this one is incorrect.
The second one is incorrect, because the value of the g(x) at 0 is 9, but he function is less at other values such as when x is -3 and the g(x) is 0.
The maximum value of the g(x) is 9. We can tell this because points with an equal difference of x values away from x = 0 (where g(x) = 9), also have the same y values. Because 9 is twice of 4.5, and 4.5 is the maximum value of the f(x), the third one is correct.
Lastly, The last one is true, because quadratic functions only have a minimum or a maximum value and we already know that both of these functions have a maximum value.

Rhea had a score of a 70 on her first quiz and a score of a 77 on her second quiz. What is the percent increase from her first quiz score to her second quiz score?
The answer is:
The percent increase from her first quiz score to her second quiz score is 10%.
Why?To know what is the percent increase from her first quiz to her second quiz, first we need to calculate the increase points, then, represent it in porcentage value.
Then, calculating her increas in points, we have:
[tex]Increase=SecondQuizScore-FirstQuizScore\\Increase=77points-70points=7points\\Increas=7points[/tex]
Now, calculating the percent increase, we have:
[tex]Increase(Percentage)=\frac{Increase(points)}{FirstScore}*100\\\\Increase(Percentage)=\frac{7}{70}*100\\\\Increase(Percentage)=0.10*100=10[/tex]
Hence, the percent increase from her first quiz score to her second quiz score is 10%.

10%
Step-by-step explanation:
increase percentage is = difference /initial value x 100

Which expression represents the area of the rectangle
(2x+7)(4x+5)?
So we'll do FOIL (first, outer, inner, last)
The equation is (4x+5)(2x+7)
First, 4x·2x=8x²
Outer, 4x·7=28x
Inner, 5·2x=10x
Last, 5·7=35
Add like terms and you get:
8x²+38x+35
The area of the rectangle represented by the expression (2x+7)(4x+5) is calculated by distributing and combining like terms, yielding the answer 8x^2 + 38x + 35.
Explanation:The expression (2x+7)(4x+5) represents the area of rectangle in Algebra. The area of a rectangle is calculated as length times width, and in this case, the length is 2x+7 and the width is 4x+5.
To calculate the area, we will need to multiply these two expressions, also known as using the distribution property of multiplication over addition.
Apply the distributive property:
2x * 4x = 8x^22x * 5 = 10x7 * 4x = 28x7 * 5 = 35Combine like terms:
8x^2 + 10x + 28x + 35 = 8x^2 + 38x + 35.So, the area of the rectangle is represented by the expression 8x^2 + 38x + 35.

She ordered 4 pizzas, she realizes that her son invited more people than she thought, so she decides to order 1 more pizza for every 3 people that come to the party. The total number of pizzas, y , can be expressed in terms of the number of people that show up to the party, x . which inequality represents this situation?
y = -one third x + 4
y = one third x + 4
y = 3x - 4
y = 3x + 4
Answer:
y = 3x + 4
Step-by-step explanation:
3x would be the number of people that show up to the party times the number of pizza's needed plus the 4 she already ordered
Find the values for c and d that would make the following equation true. (cy^2)(4y^d)=-20y^3
Answer:
c = -5 and d = 1
Step-by-step explanation:
First, multiply out (cy^2)(4y^d). We get: 4cy^(2+d).
We equate this result to the right side of the equation: - 20y^3.
Then, equating the exponents and solving for d, we get: 2 + d = 3, or d = 1.
Equating the coefficients, we get 4c = -20, or c = -5.

Which graph matches the equation y = -(x-2)2
The equation y = -(x-2)² represents a parabola opening downwards with a vertex at (2, 0). To find the matching graph, plot several points by calculating y for chosen x values and then connect the points to reveal the parabola's shape.
Explanation:The student is asking for the graph that matches the equation y = -(x-2)². This equation represents a parabola that opens downwards due to the negative sign in front of the parenthesis. To plot this, we'll need to create a table of values by choosing different x values, inserting them into the equation, and calculating the corresponding y values. After plotting these points, we'll see the shape of the parabola. Its vertex, the highest point on the graph due to the downward opening, will be at (2, 0) since the equation is in the form y = -a(x - h)², where (h, k) is the vertex of the parabola.
Steps for Plotting:Choose x values around the vertex (2, 0).Calculate y for each x.Plot the points on the coordinate plane.Connect the points to form a parabola.Simplify the expression. X^2-x/2x-2x^2
