The following shape has 1 pair of parallel sides.
What is the area of the shape?
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.

The weights (in ounces) of several moon rocks are shown in the table. Find the mean, median, and mode of the weights. Moon Rock Weights (ounces) 2.2 2.2 3.2 2.4 2.8 3.4 2.6 3.0 2.5
Answer:
the mode that repeats the most is 2.2 becuase to find it you need to find the number that repeats the most in the table. To find the median you add all the numbers and divide them to get the answer that is 2.7 for the mean but to find the median you need to order them from least to greatest and the answer you get for the median is 2.6 so hopefully that is the correct answer for all of them.

How many times bigger is 3.45×10⁹ than 0.5×10⁴
Answer:
It's 50,000 times bigger.
Step-by-step explanation:
3×10¹⁵ ÷ 6×10¹⁰ = (3 ÷ 6)×(10¹⁵÷10¹⁰) = 0.5×10¹⁵⁻¹⁰ = (5×10⁻¹)×10⁵ = 5×10⁻¹⁺⁵ = 5×10⁴ It is 5×10⁴ (= 50,000) times bigger.
A table has a wooden support that is in the approximate shape of a cone. The base of the cone has an area of about 201.1 square inches. If the volume of the cone is about 2,144.7 cubic inches, what is the height?
Answer choices:
A)
28 in.
B)
30 in.
C)
32 in.
D)
40 in.
The height of a cone with a volume and base area of 2,144.7 cubic inches and 201.1 square inches respectively is 32 inches
How to find height of a cone using the volume formula?volume of a cone = 1 / 3 πr²h
where
r = radiush = heightTherefore,
volume of the cone = 2,144.7 cubic inches
Base area = 201.1 square inches.
πr² = Base area
Therefore,
2144.7 = 1 / 3 × 201.1 × h
6434.1 = 201.1 h
h = 6434.1 / 201.1
h = 31.9945300845

2) y=7 (4,7)
3) y=8 (5,8)
4) y=9 (6,9)
Step-by-step explanation:
These are the answer because you are just adding 3 to the x coordinate which will be the number for the y coordinate.

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)
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.

Sanjay called random phone numbers in his state until he reached 1,000 people. Among those who answered the phone, 385 consented to participate in Sanjay's survey.
Is this a random sample of the people in the state?
Answer as Yes or No
Answer: NO
Step-by-step explanation:
This is because if you think about it, only the people that want to do the survey do it. Those who dont want to do it dont have to. This makes it voluntary. Any time the surveyed person gets to choose if they can do it it is voluntary. Furthermore, If it is voluntary it can usually represent all of the different peoples. But in this case, the shy people dont get a say because they would choose to not survey. So the shy people would not be represented. That is why this isn't random.

James had 25% more paper clips than Andy. Mary had 70 paper clips. If the three of them had 520 paper clips altogether, express Mary's paper clips as a percent of Andy's paper clips.
Answer:
Percentage is a part of a whole. The percentage change in the number of paper clips is 12.5%.
Given to us
Number of Paper clips Initialy= 72
Number of Paper clips now = 63
We know that the paper clip, in the beginning, was 72 but later on it was reduced to 63. therefore, the paper clips were reduced from the initial value.
\text{Percentage change} =\rm \dfrac{Initial\ value\ - final\ value}{Initial\ value} \times 100Percentage change=

Substitute the value,
\text{The percentage change in the paperclip } =\rm \dfrac{Initial\ value\ - final\ value}{Initial\ value} \times 100The percentage change in the paperclip =
Initial value
Initial value −final value
×100
\begin{gathered}\begin{aligned}\text{The percentage change in the paperclip } &=\rm \dfrac{72-63}{72} \times 100\\\\&= 12.5\% \end{aligned}\end{gathered}
The percentage change in the paperclip

He can also choose three people or more by asking them to raise their hand who wants to be a volunteer and do not raise their hand if they dont want. So hopefully those are the two ways.
