May you please help me figure out every angle?
Answer:
<D = 82°
<E = 49°
<F = 49°
Step-by-step explanation:
This is an isosceles triangle because two of the sides are the same length which means the 2 bottom angles are the exact same which means we can set them equal to each other to solve for it.
Rory earned an 84% on his test. He answered 21 questions correctly. How many total questions were on the
test? Round to the nearest tenth if necessary
Answer:
25 questions,
$18.75
Step-by-step explanation:
Remember, to change percents to decimals, divide the number by 100 and remove the parentheses.
1. 84%, or 21 questions of Roy's test were correct.
Let's set the number of questions on the test as "x". We can then write this equation:
84% * x = 21
Simplify.
0.84 * x = 21
Divide both sides by 0.84
x = 25
There were 25 questions on the test.
2. Cheesecake Factory question
We need to find 15% of 125.
15% * 125 =
0.15 * 125 =
18.75
They need to leave a $18.75 tip.

A car travels 6 mile in 2 hours what is the unit rate
A 3 miles/ hour
B 1 mile/3 hour
C 3 /1 mile
D6 miles/ 1 hour
Answer:
A
Step-by-step explanation:
This is a fraction equal to
6 miles ÷ 2 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2
6 miles ÷ 2 2 hours ÷ 2= 3 miles1 hour= 3 miles hour = 3 miles per hour

Determine whether the following graph can represent a normal curve.
Could the graph represent a normal curve? Select all that apply.
Answer:
C
Step-by-step explanation:
A normal curve describes a unimodal curve... this has 2 peaks (bimodal)
**this looks like stats?**
The graph does not represent a normal curve since:
No, because the graph has multiple peaks.No, because the graph approaches the X-axis as X increases and decreases without bound.Graphically speaking, the probability density function of a normal distribution has the following characteristics:
It has a single "peak" at a value of [tex]x[/tex] associated to the mean.The function is distributed symmetrically.The y-value of the function tends to be zero when [tex]x \to \pm \infty[/tex].The curve presented in the image only observes the condition described in 2. Therefore, we conclude that correct choices are:
No, because the graph has multiple peaks.No, because the graph approaches the X-axis as X increases and decreases without bound.We kindly invite to check this question on normal curves: https://brainly.com/question/15992479

Part 1: Identify key features and graph a parabola from standard form.
Answer the following questions to determine the key features of the parabola based on the
equation shown, and then graph it.
12(x + 3) = (y - 2)^2
a) What is the axis of symmetry of the parabola? Explain how to determine this from the equation.
(1 point)
b) What is the vertex of the parabola? (1 point)
c) What is the focus of the parabola? (2 points)
d) What is the directrix of the parabola? (2 points)
e) Sketch a graph of the parabola and label the vertex, focus, directrix, and axis of symmetry. (4 point
Answer:
a) The axis of symmetry is the line, y = 2
b) The vertex of a parabola is (-3, 2)
c) The focus of the parabola is (0, 2)
d) The directrix of a parabola is, x = -6
e) Please find attached the graph of the parabola
Step-by-step explanation:
a) The function for the parabola can be expressed as follows;
12·(x + 3) = (y - 2)²
The general form of the equation of the parabola is x = a·(y - k)² + h
The axis of symmetry is the line, y = k
By comparison, with the given equation of the parabola, we have;
12·(x + 3) = (y - 2)²
x = (1/12)·(y - 2)² - 3
Therefore;
a = (1/12), k = 2, h = -3
The axis of symmetry is y = k
∴ The axis of symmetry is the line, y = 2
b) The vertex of a parabola = (h, k)
∴ The vertex of a parabola = (-3, 2)
c) The focus of a parabola is [tex]\left(h + \dfrac{1}{4\cdot a} , \ k\right)[/tex]
Therefore, the focus of the parabola is [tex]\left(-3 + \dfrac{1}{4\cdot \dfrac{1}{12} } , \ 2\right)[/tex] = (0, 2)
The focus of the parabola = (0, 2)
d) The directrix of a parabola is [tex]h - \dfrac{1}{4\cdot a}[/tex]
[tex]\therefore h - \dfrac{1}{4\cdot a} = -3 - \dfrac{1}{4\cdot \dfrac{1}{12} } = -3 - 3 } = -6[/tex]
The directrix of a parabola is, x = -6
e) Please find attached the graph of the parabola, showing the vertex, focus, directrix, and axis of symmetry, created with Microsoft Excel
The axis of symmetry of the parabola is y = 2, the vertex of the parabola is (-3, 2), the focus of the parabola is (0, 2) and the directrix of the parabola is x = -6
It is given that the parabola equation is [tex]\rm 12(x+3)=(y-2)^2[/tex]
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We know the standard form of a parabola is:
[tex]\rm x= a(y-k)^2+h[/tex] .........(1)
We have the equation of parabola:
[tex]\rm 12(x+3)=(y-2)^2\\\\\rm x+3 =\frac{1}{12} [(y-2)^2]\\\\\rm x =\frac{1}{12} [(y-2)^2]-3\\[/tex]........(2)
a) Axis of symmetry: the axis of symmetry is a straight line that divides the parabola into two identical parts.
By comparing the equation (1) and (2), we get:
Axis of symmetry ⇒ (y - k) = 0 ⇒ (y - 2) = 0 ⇒ y = 2.
b) Vertex of the parabola = (h,k): (-3, 2)
c) The focus of the parabola is [tex]\rm (h+\frac{1}{4a} ,k)[/tex],
[tex]\rm h = -3, a = \frac{1}{12} , k= 2[/tex]
∴ [tex]\rm (-3+\frac{1}{4\times(\frac{1}{12}) } ,2)\\\\\rm (0,2)[/tex]
The focus of the parabola is (0, 2)
d) The directrix of a parabola is [tex]\rm x = h-\frac{1}{4a}[/tex]
[tex]\rm x = -3-\frac{1}{4\times\frac{1}{12} }\\\\\rm x= -3-3\\\rm x= -6[/tex]
The directrix of a is x = -6
e) Shown in the below picture: graph of the parabola and vertex, focus, directrix, and axis of symmetry
Thus, the axis of symmetry of the parabola is y = 2, the vertex of the parabola is (-3, 2), the focus of the parabola is (0, 2) and the directrix of the parabola is x = -6

cost price of television is Rs 40000.The profit is 1/9 of selling price ,find the selling price .
Answer:
₹45000
Step-by-step explanation:
Let the selling price (SP) of the television be ₹x.
Therefore,
Profit [tex] =\frac{1}{9}x[/tex]
Cost price (CP) = ₹ 40000
[tex]Profit = SP - CP \\ \\ \frac{1}{9}x = x - 40000 \\ \\ \frac{x}{9} - x = - 40000 \\ \\ \frac{x - 9x}{9} = - 40000 \\ \\ - \frac{8}{9} x = - 40000 \\ \\ x = 40000 \times \frac{9}{8} \\ \\ x = 5000 \times 9 \\ \\ x = 45000[/tex]

Answer:
n = [tex]\frac{4}{3}[/tex]
or (because the wording is kind of confusing)
n = [tex]\frac{20}{3}[/tex]
Step-by-step explanation:
9(4 - n) = 24
36 - 9n = 24
-9n = -12
n = [tex]\frac{4}{3}[/tex]
or (because the wording is kind of confusing)
9(n - 4) = 24
9n - 36 = 24
9n = 60
n = [tex]\frac{20}{3}[/tex]

Equations are [tex]3x-y=23[/tex] and [tex]2x+3y=8[/tex]
take [tex]3x-y=23[/tex]
[tex]y=3x-23[/tex]
Put the value of y in another equation
[tex]\Rightarrow 2x+3(3x-23)=8\\\Rightarrow 2x+9x-69=8\\\Rightarrow 11x=77\\\Rightarrow x=7[/tex]
Put the value of x in y
[tex]y=3(7)-23=21-23=-2[/tex]
Hence, [tex]x=7, \ y=-2[/tex]

Answer:
$9.80
Step-by-step explanation:
Remember that the way to find the mean of a data set is by adding together all the values, and dividing by the number of the values. So, in this case, you add the 5 values together and get 49. Since there are 5 values, you divide 49 by 5 and get 9.8, or in a real world-money situation $9.80.

23°, 17°, 26°, 5°, 33°, 11°
A. 19°
B. 20°
C. 26°
D. 28°
Answer:
A. 19°
Step-by-step explanation:
To find the average of something, you add every number in the sequence and then divide it by how many numbers there are.
23 + 17 + 26 + 5 + 33 + 11 = 115
115 / 6 = 19.16666666666667
Round it down and your answer will be 19°.
