Right angle triangle goes to 15m, 8m, 17m
Step-by-step explanation:
Square root of 15^2 + 8^2 is 17
(The use of a^2 + b^2 = c^2 - Pythagoras's Theorem)
So, 10m ,11m ,15m isn't a right angle triangle

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!

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
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 height of a right rectangular prism is 3 units greater than the length of the base. the edge length of the square base is x units. which expression represents the volume of the prism, in cubic units? x3 9 x3 3x2 x3 3x 3 x3 6x2 9x
The equation for the volume of the prism will be given as V=x^3+3x^2
What will be the equation of volume of the prism?The volume of the prism is given by the following formula
[tex]\rm Volume = Width\times Length\times hieght[/tex]
Here we have a condition in the question that
The height of a right rectangular prism is 3 units greater than the length
[tex]h=x+3[/tex]
length will be l = x
The width will be w=x
now by putting the value in the formula we get

An incident ray of light strikes water at an angle of 30°. The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33. What is the angle of refraction rounded to the nearest whole number? 22° 24° 30° 42°.
The measure of the angle of refraction is 22 degress, the correct option is A.
What is the angle of refraction?
The angle made by a refracted ray with a perpendicular to the refracting surface.
Given
An incident ray of light strikes water at an angle of 30°.
The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33.
In order to determine the angle of the refracted ray, we may apply Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is constant for a given wave when it passes through two different media.
The angle of the refraction is given by;
[tex]\rm 1.0003 \times sin(30) = 1.33 \times sin(\phi)\\\\ \rm 1.0003 \times 0.5 = 1.33 \times sin(\phi)\\\\Sin\phi=\rm \dfrac{1.0003 \times 0.5 }{1.33}\\\\Sin\phi=0.37\\\\\phi = 22[/tex]
Hence, the measure of the angle of refraction is 22 degress.

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).

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.Find ABC
