Answer:
98 degrees
Step-by-step explanation:
The angles of a quadrilateral add up to 360 degrees, therefore:
(25x+1)+(25x-2)+(20x-1)+82=360
70x +80=360
70x=280
x=4
the angle at C:
25*4-2 = 98 degrees

Can you please factor the problems below and explain/show all your steps. I will be attaching a photo with the problems as well in case they are more understandable on there. Also if you can please explain how you used the key concepts from the photo in your work if you used them.
Factor: 2a^3 + 4a^2 + 8a
Factor: 6y^4 - 294y^2
Factor: 5x^2 + 50x +125
---------------------------------------
To factor each expression, we apply the given concepts, that is, greatest common factor, difference of squares and perfect squares.
---------------------------------------
Expression 1:
The expression is:
[tex]2a^3 + 4a^2 + 8a[/tex]
First, we find the gcf of the numbers 2, 4 and 8, which is 2.
Of the exponents, the gcf between 3, 2 and 1 is 1, so:
[tex]2a^3 + 4a^2 + 8a = 2a(\frac{2a^3}{2a} + \frac{4a^2}{2a} + \frac{8a}{2a}) = 2a(a^2 + 2a + 4)[/tex]
---------------------------------------
Expression 2:
The expression is:
[tex]6y^4 - 294y^2[/tex]
The gcf of 6 and 294 is 6.
The gcf of the exponents 2 and 4 is 4.
Thus:
[tex]6y^4 - 294y^2 = 6y^2(\frac{6y^4}{6y^2} - \frac{294y^2}{6y^2}) = 6y^2(y^2 - 49)[/tex]
Then, applying the difference of squares:
[tex]y^2 - 49 = (y - 7)(y + 7)[/tex]
Thus, the factored expression is:
[tex]6y^2(y^2 - 49) = 6y^2(y - 7)(y + 7)[/tex]
---------------------------------------
Expression 3:
The expression is:
[tex]5x^2 + 50x + 125[/tex]
The gcf of the coefficients, 5, 50 and 125 is 5, so:
[tex]5(\frac{5x^2}{5} + \frac{50x}{5} + \frac{125}{5}) = 5(x^2 + 10x + 25)[/tex]
Applying the perfect square, we get that:
[tex]x^2 + 10x + 25 = (x + 5)^2[/tex]
Tus, the factored expression is:
[tex]5(x^2 + 10x + 25) = 5(x+5)^2[/tex]

Step-by-step explanation:
These are geometric means problems. In the top one, a is the geometric mean as the height for both the smaller triangles inside the big one. Therefore,
[tex]\frac{4}{a} =\frac{a}{25\\}\\a^2=100\\a=10[/tex]
The next one has the geometric mean of b, being a part of the smaller triangle on the left and the big triangle as a whole:

Very quick definition: What do you call the relation between two points that have one or more points in between them? For example, in a square ABCD, A and C would have B in between and in a pentagon VWXYZ, V and X would have W in between them and V and Y would have both W and X between. So basically like non consecutive points? Please tell me if I make no sense I honestly don't know how to word it :P
Answer:
Step-by-step explanation:
Well believe it or not, that is not a simple question. Just look at what you left us to define. Your talking (for example) about a square and wondering what the vertex of B is called (other than a vertex.)
I think vertex is the only thing you can call B. But then there's a problem. What do you call the points on a segment? ___________? There are endpoints, but what's between those endpoints? I think you would just give them letter names and call them points. A point is dimensionless and there an infinite number of them in a segment.

is three a solution of z^2 +1=4+3z?
Answer:
no
Step-by-step explanation:
z^2 +1=4+3z
Substitute into the equation and see if it is true
3^2 +1 = 4+3(3)
9+1 = 4+9
10 = 13
This is not a true statement so this is not a solution
The dimensions of four rectangles are given below. Which has an area different from the area of each of the other three?
To determine which of the rectangles has a different area, the areas of the four rectangles must be calculated. The rectangle with a different area is rectangle b
The dimension of the 4 rectangles are:
a. length: 4x and width: 4
b. length: 11 and width: x
c. length: 2 and width: 8x
d. length: 16x and width: 1
The area of a rectangle is:
[tex]Area = Length \times Width[/tex]
Rectangle (a)
[tex]Area = 4x \times 4[/tex]
[tex]Area = 16x[/tex]
Rectangle (b)
[tex]Area = 11 \times x[/tex]
[tex]Area = 11x[/tex]
Rectangle (c)
[tex]Area = 2 \times 8x[/tex]
[tex]Area = 16x[/tex]
Rectangle (d)
[tex]Area = 16x \times 1[/tex]
[tex]Area = 16x[/tex]
Rectangles (a), (c) and (d) have the same area (i.e. 16x) while rectangle (b) has 11x as its area.
Hence, the rectangle with a different area is rectangle (b).

The width of a rectangle is 9
inches less than the length. The
perimeter is 86 inches
Answer:
Below.
Step-by-step explanation:
If the length is x then the width is x-9 inches.
Perimeter
= 2L + 2W = 86
2x + 2(x - 9) = 86
4x - 18 = 86
4x = 104
x = 26
So the length is 26 inches and the width is 17 inches.

Answer:
165.7 or 166
Step-by-step explanation:
since the adjacent has already been given which is 113 you have to use the cos ratio to find the hypotenuse
cos47=adjacent/hypotenuse
cos47=113/h
cos47h/cos47=113/cos47
hypotenuse=166
I hope this helps
Answer:
Hypotenuse is 165.689
Step-by-step explanation:
For this question you will be using cosine.
You start solving this problem as C (cosine) = A/H (adjacent over hypotenuse).
COS(47) / 1 = 113/H
Meaning cosine of 47 over 1 is equal to 113 over H (hypotenuse).
Next you cross multiply leaving you with 113/ COS47 = COS47 x H
Next you divide both sides by COS47 x y
and divide 113 by COS47 and get your answer.

In a large restaurant, an average of 3 out of every 5 customers ask for water with their meal. A random sample of 10 customers is selected. Find the probability that exactly 6 ask for water with their meal. Let X be the random variable that represents the number of these customers who ask for water.
Answer:
please mark me brainlist
Step-by-step explanation:
a) Let X be the random variable the number of customers asking for water.
X ~B(10,0.6)
= P(X = 6) =( 0.6)6 ( 0.4)4 10!/6 !*4!
= 0.2508
Y ~B(10,0.4)
= P(Y = 4)=( 0.6)6 ( 0.4)4 10!/6 !*4!
= 0.2508
The probability that exactly 6 ask for water with their meal is calculated by binomial distribution and the value is P ( x = 6 ) = 25.08 %
What is a Binomial Distribution?
The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.
The formula for Binomial Distribution is given by
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
where
n = number of trials
x = number of successes
p = probability of getting a success in one trial
q = probability of getting a failure in one trial
q = 1 - p
Given data ,
Let the probability that exactly 6 ask for water with their meal be P ( x = 6 )
Now , an average of 3 out of every 5 customers ask for water with their meal
So , the probability of getting a success p = 3/5 = 0.6
The probability of getting a failure q = 1 - p = 0.4
The number of trials = 10
The number of successes x = 6
So ,
Probability that exactly 6 ask for water with their meal be P ( x = 6 ) is
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
Substituting the values in the equation , we get
P ( x = 6 ) = [ 10! / ( 4 )! 6! ] ( 0.6 )⁶( 0.4 )⁴
On simplifying the equation , we get
P ( x = 6 ) = 0.2508
P ( x = 6 ) = 25.08 %
Therefore, the value of P ( x = 6 ) is 25.08 %
Hence , probability that exactly 6 asks for water is 25.08 %

is an element.
A. rational numbers
B. natural numbers
C. whole numbers
D. irrational numbers
E. real numbers
F. integers
Answer:
A
E
Step-by-step explanation:
a rational number can be expressed as fraction. well, that is what the number 8/9 is.
so, A is a correct option.
as such it is automatically also a member of the real numbers (which is a superset of rational numbers). so, E is a correct option.
all other options are wrong.
8/9 is not a natural number (1, 2, 3, 4, ...).
it is not a whole number (0, 1, 2, 3, 4, ...).
it is not an integer (... , -2, -1, 0, 1, 2, 3, ...).
and as it is a rational number, it is automatically not an irrational number.

Answer:
Sides = 3.2
Diagonals = 4.5
Shape = Square
Step-by-step explanation:
a) i) Distance from P to Q= 3.162278 which is approx 3.2.
So to calculate your answer you use the distance formula. The formula is the square root of (x2 - x1) + (y2 - y1).
So all sides of the shape have a length of 3.2 because the shape is a square.
DIAGONALS:
QS = 4.472136 approx 4.5
For:
(X1, Y1) = (-3, -2)
(X2, Y2) = (-1, 2)
We use the same formula for distance.
