How does the dot plot work?Suppose we're measuring something whose values are numeric. For each value of that thing we observe, we plot a dot above that value in the number line. Thus, the total number of dots in the dot plot tells us the total number of observations of the values of that thing we did.
The line plot below shows the heights of flowers grown by the students in one of the fifth-grade classes. Persia makes a flower arrangement using the 8 longest flowers.
Then the combined height of the flowers Persia uses will be
→ 6.5 + 6.75 + 7 + 7.25 + 7.5 + 7.75 + 8.5 + 10
→ 61.25
The number 61.25 can be written as
→ 61 and 1/4 inches

The following shape has 1 pair of parallel sides.
What is the area of the shape?
Answers
Answer:
57
Step-by-step explanation:
There's three shapes, 2 triangles and 1 rectangle.
1. To find the area of a rectangle multiply the legth x width, so 5*2, which is 10.
2. To find the area of a traingle multiply the length and width, and then divide that by two. For the smaller triangle do 6*5, which is 30, and divide that by 2 for 15.
3. The big triangle shows the length of one side but not on the other. Because the length of the rectangle is the same on both sides, and the length 3 and 5 are on the same line, the other length of the large triangle is 8.
4. 8*8 is 64, and dividing that by 2 is 32.
5. Add all of the numbers: 10+15+32, which is 57.
The area of a 2D form is the amount of space within its perimeter. The total area of the given figure is 57 inches².
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Let the given figure be divided into three parts. Such that the triangle on the left side or the bigger triangle is represented by A and the triangle on the right side of the smaller triangle is represented by B. The area of the given shape can be written as,
Area of triangle A = 1/2 × Height of triangle A × Base of the triangle A = 1/2 × 8 inches × 8 inches
= 32 inches²
Area of rectangle = Length × Breadth
= 5 inches × 2 inches
= 10 inches²
Area of triangle B = 1/2 × Height of triangle B × Base of the triangle B = 1/2 × 5 inches × 6 inches
= 15 inches²
Further, the total area of the shape can be written as,
Total area = 32 inches² + 10 inches² + 15 inches²
= 57 inches²
Hence, the total area of the given figure is 57 inches².

Is it possible for these two triangles to be similar? Why or why not?
Answers
Answer:
Angle C= 79 degrees
Angle X= 62 degrees
Yes, the two triangles are similar because all the angles are congruent. The requirement for two triangles to be similar is if two corresponding angles are equal.
Step-by-step explanation:
A triangle is 180 degrees.
So adding the angles of triangle ABC, 62+39=101
180-101=79, so angle c is 79 degrees
Adding the angles of triangle XYZ, 39+79=118
180-118=62, so angle x is 62 degrees
Answer:
Angle C= 79 degrees
Angle X= 62 degrees

Use the function f(x) to answer the questions:
f(x) = 4x2 − 7x − 15
Part A: What are the x-intercepts of the graph of f(x)? Show your work. (2 points)
Part B: Is the vertex of the graph of f(x) going to be a maximum or a minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answers
Part A: x = -5/4, 3 || (-5/4, 0) (3, 0)
To find the x-intercepts, we need to know where y is equal to 0. So, we will set the function equal to 0 and solve for x.
4x^2 - 7x - 15 = 0
4 x 15 = 60 || -12 x 5 = 60 || -12 + 5 = -7
4x^2 - 12x + 5x - 15 = 0
4x(x - 3) + 5(x - 3) = 0
(4x + 5)(x - 3) = 0
4x + 5 = 0
x = -5/4
x - 3 = 0
x = 3
Part B: minimum, (7/8, -289/16)
The vertex of the graph will be a minimum. This is because the parabola is positive, meaning that it opens to the top.
To find the coordinates of the parabola, we start with the x-coordinate. The x-coordinate can be found using the equation -b/2a.
b = -7
a = 4
x = -(-7) / 2(4) = 7/8
Now that we know the x-value, we can plug it into the function and solve for the y-value.
y = 4(7/8)^2 - 7(7/8) - 15
y = 4(49/64) - 49/8 - 15
y = 196/64 - 392/64 - 960/64
y = -1156/64 = -289/16 = -18 1/16
Part C:
First, start by graphing the vertex. Then, use the x-intercepts and graph those. At this point we should have three points in a sort of triangle shape. If we did it right, each of the x-values will be an equal distance from the vertex. After we have those points graphed, it is time to draw in the parabola. Knowing that the parabola is positive, we draw in a U shape that passes through each of the three points and opens toward the top of the coordinate grid.
Hope this helps!
Answer:
Give the other guy brainliest
Step-by-step explanation:
Part A: The x-intercepts are (-5/4, 0) and (3, 0)
0=4x^2-7x-15
0=4x^2-12x+5x-15
0=4x(x-3)+5(x-3)
0=(4x+5)(x-3)
Basic math:
x=-5/4
x=3
Part B: The vertex is going to be minimum because if a>0, then the parabola opens up and it is a minimum (a as in ax^2+bx+c).
In order to find the vertex's coordinates, we can use -b/2a. In the equation, b=-7, and a=4. The formula would look like or 7/8. We now know the x coordinate. We can use that to find the y value.
y=4(7/8)^2-7(7/8)-15=y=18 =-18.0625=289/16
Part C: Graph the x-intercepts found in part A, then graph the vertex found in part B. Then graph a U shape that opens up going through all the points to make the parabola. Because it is positive, the U will face up, not down.

A circular hot spring has a diameter of 96 meters. Over time, the diameter of the spring decreases by 8 meters. By how many square meters does the area of the hot spring decrease? Use 3.14 for pi
Answers
Answer:
The area decreases by 1155.52 square meters
Step-by-step explanation:
What we must do is calculate the area before and after making the diameter cut.
The area of a circle is equal to:
a = pi * r ^ 2
now the diameter is equal to:
d = 2 * r
therefore r,
r = d / 2
before the cut would be
r = 96/2
r = 48
replacing in the area formula
a1 = 3.14 * 48 ^ 2
a1 = 7234.56 square meters.
after cutting the diameter decreases by 8, that is, 96 - 8 = 88, calculating the radius would be:
r = 88/2
r = 44
now calculating the new area would be:
a2 = 3.14 * 44 ^ 2
a2 = 6079.04 square meters.
now we calculate the difference
a1 - a2 = 7234.56 - 6079.04
= 1155.52 square meters
means that the area decreases by 1155.52 square meters

From the stem and leaf plot, we get the following data points-
10, 23, 23, 28, 33, 45, 80, 90
First of all, the data should be arranged in the ascending order. The given data is already in the ascending order, so we can proceed directly.
The formula that is used to calculate the IQR is Q3-Q1, which is the difference between the third and the first quartile of the given data.
Now we need to find the median for the data given for the second quartile. Median is the average of the two central values- 28 & 33.
Hence we get Q2 = (28 + 33) / 2 = 30.5.
Now we find the median for Q1, which is the median of the lower part of the given data which is 10, 23, 23, & 28. (23 + 23) / 2 = 23.
Similarly, for Q3, which is the upper part- 33, 45, 80, and 90. We get (45 + 80) / 2 = 62.5.
Now we should subtract Q1 from Q3: Q3 - Q1 = 62.5 - 23 = 39.5.
So, the interquartile range is 39.5.

Assume these two equations:

If (a1/a2) = (b1/b2) ≠ (c1/c2) than those two would have no solution.
In these case, take a look at the last option:
[tex]3x + y = 8 \\ 3x + y = 9[/tex]
Re-write 'em as a standard form:

Our question is:
[tex](\frac{1}{3})^{2}[/tex] × [tex](\frac{1}{3})^x[/tex] = [tex]\frac{1}{729}[/tex]
If we don't want to evaluate any powers at all we'll have to make each term have the same base (so that we can ignore the base — [tex]\frac{1}{3}[/tex])
we need to figure out what power of a [tex]\frac{1}{3}[/tex] the [tex]\frac{1}{729}[/tex] is.
what we can do is the following:
[tex](\frac{1}{3})^?[/tex] = [tex]\frac{1}{729}[/tex]
[tex]3^?[/tex] = 729
If we take the "log" of each, we can find out what power of 3 gives 729.[tex]log(3^?) = log\ 729[/tex]
We must remember this rule: [tex]log(a^n) = n \times log(a)[/tex]
[tex]? \times log 3 = log 729[/tex]
[tex]? = \frac{log\ 729}{log\ 3}[/tex]
? = 6 (with a calculator)
This means that to get 729, we need to do [tex]3^6[/tex]
Therefore [tex](\frac{1}{3})^6 = \frac{1}{729}[/tex]
We can now solve the equation!
[tex](\frac{1}{3})^{2}[/tex] × [tex](\frac{1}{3})^x[/tex] = [tex]\frac{1}{729}[/tex]
[tex](\frac{1}{3})^{2}[/tex] × [tex](\frac{1}{3})^x[/tex] = [tex](\frac{1}{3})^6[/tex]
Since each term of our equation has the same base of [tex]\frac{1}{3}[/tex] we can ignore it and just deal with the powers!
We must remember this rule: [tex]x^a \times x^b = x^{a + b}[/tex]
Using this rule:
[tex](\frac{1}{3})^{2}[/tex] × [tex](\frac{1}{3})^x[/tex] = [tex](\frac{1}{3})^6[/tex] becomes...

MH is a two digit number, and TM is also a

MH+MH+MH=3*MH<100
3M<=9, meaning that M could be 1, 2, or 3.
If M=1,
MH+MH+MH=3(10+H)=30+3H=TM=10*T+1
30+3H=10T+1, so 3H must include 1 in one's
digit.
The only possibility is that 3H = 21, then H = 7
MH+MH+MH=17+17+17=TM=51, T = 5
If M=2.
MH+MH+MH=3(20+H)=60+3H=TM=10T+2
60+3H=10T+2, so 3H must include 2 in one's
digit.
The only possibility is 3H = 12, then H = 4
MH+MH+MH=24+24+24=72, T = 7
IT IM=4,
MH+MH+MH=3(20+H)=60+3H=TM=10T+2
60+3H=10T+2, so 3H must include 2 in one's
digit.
The only possibility is 3H = 12, then H = 4
MH+MH+MH=24+24+24=72. T=7
If M=3.
MH+MH+MH=3(30+H)=90+3H=TM=10T+3
90+3H=10T+3, so 3H must include 3 in one's
digit.
The only possibility is 3H = 3, then H =1
