Answer: always
Step-by-step explanation:
A right triangle is a kind of triangle with one right angle.
Side opposite to right angle is known as hypotenuse.Other two sides is known as legs.A theorem of right triangle says that :-
When the altitude drawn from the right angle to the hypotenuse splits the hypotenuse into two sections of segments. Then the length of each leg of the right triangle is the geometric mean of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.Hence, the statement "The altitude to the hypotenuse of a right triangle is the geometric mean between the segments on the hypotenuse." is always true.
Thus , the correct answer is "always".
Your answer should be always :)

Step-by-step explanation:
Explain the special pattern for sketching a parabola
Answer:
the parabola can be written as:
f(x) = y = a*x^2 + b*x + c
first step.
find the vertex at:
x = -b/2a
the vertex will be the point (-b/2a, f(-b/2a))
now, if a is positive, then the arms of the parabola go up, if a is negative, the arms of the parabola go down.
The next step is to see if we have real roots by using the Bhaskara's equation:
[tex]x = \frac{-b +-\sqrt{b^2 -4ac} }{2a}[/tex]
Now, draw the vertex, after that draw the values of the roots in the x-axis, and now conect the points with the general draw of the parabola.
If you do not have any real roots, you can feed into the parabola some different values of x around the vertex
for example at:
x = (-b/2a) + 1 and x = (-b/2a) - 1
those two values should give the same value of y, and now you can connect the vertex with those two points.
If you want a more exact drawing, you can add more points (like x = (-b/2a) + 3 and x = (-b/2a) - 3) and connect them, as more points you add, the best sketch you will have.

There are 25 students in a class. 16 of those students are boys. What percent of the class are girls?
The percent of girls in the class is ____ %
Answer:
36 %
Step-by-step explanation:
9 girls = 36%
25 students = 100
Answer:
Step-by-step explanation:
25 students in a class and 16 out of the 25 students in the class are girls. There are 9 boys in the class because "25-9=16"
HOW TO SOLVE If we know that 9 out of the 25 students in the class are girls, we can represent it as the fraction . Next, we divide 35 by 9 to get a quotient of 0.36 and then multiply by 100 to get our percent of girls in the class which is 36%
Gloria decides to buy 4 ferns, 2 Palms, 10 Lilies and 8 shrubs. To show the total
cost of the plants as an expression, first set up an expression showing how the
distributive property can shorten the process and then simplify it.
Step by step
Answer:
[tex]Total Plants = 4F + 2P + 10L+ 8S[/tex]
[tex]Total Plants = 2(2F + P + 5L+ 4S)[/tex] --- Distributive property
Step-by-step explanation:
Given
Ferns = 4
Palms = 2
Lillies = 10
Shrubs = 8
Required
Show the total cost of plants as an expression
Shorten it using the distributive property
First, represent Ferns with F; Palms with P; Lilies with L and Shrubs with S;
So, 4 Ferns = 4F
2 Palms = 2P
10 Lilies = 10L
8 Shrubs = 8S
Total Plants = Summation of the above parameters
[tex]Total Plants = 4F + 2P + 10L+ 8S[/tex]
The above expression represents the total plants bought;
Now, to apply the distributive property; we simply look for a common factor;
In this case, the common factor is 2;
So, [tex]Total Plants = 4F + 2P + 10L+ 8S[/tex] becomes
[tex]Total Plants = 2(\frac{4F}{2} + \frac{2P}{2} + \frac{10L}{2}+ \frac{8S}{2})[/tex]
[tex]Total Plants = 2(2F + P + 5L+ 4S)[/tex]

3a - 2a > - 8b -7b
a > -15b
The value of is as follows:
a > -15b
3a + 7b > 2a – 8b
The question wants us to make a the subject of the formula,
Therefore,
3a + 7b > 2a – 8b
subtract 2a from both sides
3a - 2a + 7b > 2a - 2a - 8b
a + 7b > - 8b
subtract 7b from both sides
a + 7b - 7b > - 8b - 7b
a > -15b
Therefore,
a > -15b

Find the MAD of the data set 26,34,66,71,76,82,88,95. show work
Answer:
MAD mean absolute deviation = 18.9
Step-by-step explanation:
mean: 26 + 34 + 66 + 71 + 76 + 82 + 88 + 95 = 538/8 = 67.25
26 - 67.25 = 41.25
34 - 67.25 = 33.25
66 - 67.25 = 1.25
71 - 67.25 = 3.75
76 - 67.25 = 8.75
82 - 67.25 = 14.75
88 - 67.25 = 20.75
95 - 67.25 = 27.75
(MAD) mean absolute deviation: 41.25 + 33.25 + 1.25 + 3.75 + 8.75 + 14.75 + 20.75 + 27.75 = 151.5/8 = 18.9
On a coordinate plane, a square and a point are shown. The square has points R prime (negative 8, 1), S prime (negative 4, 1), T prime (negative 4, negative 3), and U prime (negative 8, negative 3). Point S is at (3, negative 5). Square RSTU is translated to form R'S'T'U', which has vertices R'(–8, 1), S'(–4, 1), T'(–4, –3), and U'(–8, –3). If point S has coordinates of (3, –5), which point lies on a side of the pre-image, square RSTU? (–5, –3) (3, –3) (–1, –6) (4, –9)
Answer:
(–1, –6)
Step-by-step explanation:
Given that S(3, –5) was translated to S'(–4, 1), the transformation rule is (x-7, y+6). Then, the coordinates of square RSTU are:
R'(–8, 1) -> (-8+7, 1-6) -> R(-1, -5)
S'(–4, 1) -> (-4+7, 1-6) -> S(3, -5)
T'(–4, –3) -> (-4+7, -3-6) -> T(3, -9)
U'(–8, –3) -> (-8+7, -3-6) -> U(-1, -9)
The point (–1, –6) lies on the segment RU
The point that lies on a side of the pre-image is mathematically given as
x=(-1,-6)
What is a Pre-Image?A pre-image is simply a the group of chosen elements from a mapped domain to give a given subset of the codomain.
What points can be found on the pre-image, square RSTU?Question Parameter(s):
which has vertices
R'(–8, 1),
S'(–4, 1),
T'(–4, –3),
U'(–8,
Generally, the equation for the transformation is mathematically given as
(x-7, y+6).
Therefore
R'(–8, 1) --> (-8+7, 1-6)
R'(–8, 1) --> R(-1, -5)
S'(–4, 1) -=> (-4+7, 1-6)
S'(–4, 1)-> S(3, -5)
T'(–4, –3) --> (-4+7, -3-6)
T'(–4, –3 -> T(3, -9)
U'(–8, –3) --> (-8+7, -3-6)
U'(–8, –3)-> U(-1, -9)
In conclusion, point S with coordinates of (3, –5) lies within RU
x=(-1,-6)

Nine friends went on a camping trip a campsite costs 40 per night for the first 4 people and campers can pay an extra fee for each additional person if the group of friends rented one campsite for one night and paid 80 how much did the campground charge for each additional person
Answer:
8 dollars per extra person
Step-by-step explanation:
subtract the original 40 dollars from 80 ,you get 40,the probloem tells you that there is 9 people meaning there was 5 extras ,so 40/5=8
Answer:
$8 charge for each additional person
Step-by-step explanation
$40/night for each person
First 4 people already paid.
Leftover are 5 people.
9-4=5
Since first 4 people paid, the rest to be paid is $40.
$80-$40=$40
To find the charge for each person, divide the amount of money left by the amount of people left.
40÷5= 8
$8 is the additional charge for each additional person.
