The area of the shape is the amount of space on the shape
Using the assumed parameters, the area of the shape is 25 square units
How to determine the area?The question is incomplete, as the shape is not given.
Assume the shape is a trapezoid, the area of the shape would be:
A = 0.5 * (sum of parallels sides) * height
Using the assumed values, we have:
Area = 0.5 * (12 + 13) * 2
Evaluate the product
Area = 25
Using the assumed values, the area of the shape is 25 square units

Which of the following is not a characteristic of a point?
A. Flat surface
B. Named using a capital letter
C. No depth or width
D. Undefined term
Answer:
D. Undefined term
Step-by-step explanation:
Points are flat surfaces, named using a capital letter, and have no depth or width because they are on a FLAT plane. Just like lines are named "line A", are on a flat surface, and have no depth or width, points also share these characteristics because they are all on a plane. However, a point is not an undefined term, it is a defined term.
A point is a geometric feature used for the definition of geometric objects
The option which is not a characteristic of a point is option A:
A. Flat surface
The reason for the above selection is as follows:
A point in Euclidean geometry is a concept that defines an exact spatial location
The characteristics of a point are:
A point only represents position, it has no dimensions; It does not have a thickness, width, or lengthThe explanation given of a point is made by use of descriptions or examples and therefore, a point is considered an undefined termA point can be denoted or named using capital letters and represented using dotsA flat surface is defined by three noncolinear points
Therefore;
The given option which is not a characteristic of a point is therefore option A. Flat surface

please help! Find the value of the convergent series:
Answer:
2.25
Step-by-step explanation:
Notice how the common ratio is -1/3, which means the series passes part 1 of the convergence test because -1/3 is in between -1 and 1.
We can also represent this as a summation series of
[tex]Σ3( - \frac{1}{3} ) {}^{n - 1} [/tex]
Since we can represent this a summation series, we can use that convergent value is equal to
[tex] \frac{a _{1} }{1 - r} [/tex]
where a1 is initial term and r is common ratio.
R is -1/3
A1 is 3.
[tex] \frac{3}{1 - \frac{ - 1}{3} } = \frac{3}{ \frac{4}{3} } = 2.25[/tex]
So the answer is 2.25

Explain how to find the mean of a set of data
PLEASE MAKE THE ANSWER SCHOOL APPROPRIATE
Answer:
The mean is the average of a data set. You can find the mean by adding all of the numbers in the guven set of data and then divide by the total number of values in a set.
Step-by-step explanation:
for example:
2, 6, 8, 13, 16, 11, 7
add all of these numbers together
the total would be 63
there are 7 numbers in the data set so you would divide 63 by 7
the mean of the data set would be 9
Answer:
The average of the numbers is the mean. After adding up all the numbers, divide by the number of numbers. You must add all the values in a data set together and divide by the number of values in the collection to determine the mean. The end product is yours!

Is this angle supplementary or congruent? Please help.
Answer:
supplementary
Step-by-step explanation:
we have,
3x+15+2x=180
=> 5x +15 = 180
=> 5x = 180-15
=> 5x = 165
=> x = 165/5
=> x= 33
so, 3x+15 = 3*33+15
=> 99+15
=>114
2x = 2*33
=> 99
now we can check if these angles are supplementary
114 + 99 = 180
so, they are supplementary

Renee is walking to a store that is 2. 5 kilometers from her house. After 700 meters, she stops at her friend’s house
What is the distance that Renee will walk from her friend’s house to the store?
Because she stopped at her friend's house on the way to the store, it can be seen that there is no detour. This means that the distance between her friend's house to the store is a subtraction problem
2.5 km - 700m=2500m-700m=1800m or 1.8km

The following bar chart shows the number of different types of animals at two county fairs. Fair X had a total of 645 animals, and fair Y had a total of 590 animals. Which of the following statements is supported by the bar chart?
Answer:
The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.
Step-by-step explanation:
From the bar chart, we can see that 100 goats were present at fair X and Y
Let us now calculate the percentage of goats at each fair:
Fair X = 100/645 * 100 = 15.5%
Fair Y =100/590 *100 = 16.9 %
Hence there was a greater percentage of goats at fair Y than at fair X.
The bar chart is missing and so i have attached it.
Also, the question is incomplete and the missing part of the question is;
Which of the following statements is supported by the bar chart?
a) The total number of cows, pigs, and horses combined is less at fair X than at fair Y.
b) Fair X has at least 20 more chickens than fair Y.
c) At fair X, the number of sheep is twice the number of horses.
d) The percentage of all animals at fair Y that are goats is equal to the percentage of all animals at fair X that are goats.
e) The percentage of all animals at fair Y that are goats is greater than the percentage of all animals at fair X that are goats.
The only Statement that supports the bar chart is statement E.
A) Looking at the bar chart attached, we can see that;At fair X: Cows = 50, Pigs =60, Horses = 80. Total = 50 + 60 + 80 = 190
At fair Y: Cows = 60, Pigs = 80, Horses = 40. Total = 60 + 80 + 40 = 180
Total in fair X is greater than total in fair Y. Therefore statement in question is false.
B) From the bar chart;At fair X; chickens = 90
At fair Y; chickens = 80
Difference = 90 - 80 = 10
Thus,statement in question is wrong.
C) At fair X;Sheeps = 140
Horses = 80
Twice number of horses is not same as sheep. Thus, statement in question is wrong.
D) Total number of animals at fair Y = 60 + 80 + 40 + 80 + 100 + 90 + 140 = 590Percentage that are goats = 100/590 × 100 = 16.95%
Total number of animals at fair X = 50 + 60 + 80 + 90 + 100 + 125 + 140 = 645
Percentage that are goats = 100/645 × 100 = 15.5%
The percentages are not equal and so the statement in the question is wrong.
E) True because from D above percentage that are goats at fair Y are more than the percentage that are goats at fair X.Need help ASAP please

Step-by-step explanation:
Since segments JK and RQ are parallel, they are similar by both extending at the same angle and both segments formed by the parallel lines being proportional segments.Since the lengths of segments KZ and ZR are given, they are similar because they are proportional.Since vertical angles are always equivalent by the Vertical Angles Theorem, angles JZK and RZQ are congruent.Because we have 2 sides with a non-included (not in-between the two sides) angle, the triangles are similar by SSA Similarity.

Which ratios are equivalent? PLEASE EXPLAIN :D
A) 6/8, 2/3
B) 1/5, 12/15
C) 9/12, 3/4
D) 10/12, 5/7
Answer:
C) 9/12, 3/4
Step-by-step explanation:
To find which ratios are equivalent, we have to simplify them.
A)
6 and 8 have a GCF of 2, so 6/2 = 3, and 8/2 = 4. We do not get 3/4 as the fraction- we get 2/3. Thus, this cannot be the correct answer.B)
The GCF of 12 and 15 is 3, so 12/3 = 4, and 15/3 = 5. We do not get 4/5 as the fraction- we get 1/5. Thus, this cannot be the correct answer.C)
The GCF of 9 and 12 is 3, so 9/3 = 3, and the 12/3 = 4. We get the fraction as 3/4, which 3/4 = 3/4Therefore, the answer is C).
