A student examines the triangle shown above. He notices that lines BE andCD look parallel. The student claims that they are parallel by look aLone ?
what is the value of x
Answer:
20
Step-by-step explanation:
because angle 5 is found on the same line as 45 degrees (don't remember what that's called), we can subtract from 180 to find
angle 5 = 135
angle 5 and 5x+35 are alternate interior angles, so they have the same value
135=5x+35
100=5x
20=x

Find the surface area of the pyramid to the nearest whole number.
Given:
A square base pyramid whose base length is 10 in. and height of triangular surface is 4 in.
To find:
The surface area of the pyramid to the nearest whole number.
Solution:
A square base pyramid contains square base with edge 10 in. and 4 congruent triangles with base 10 in. and height 4 in.
Area of a square is
[tex]A_1=(edge)^2[/tex]
[tex]A_1=(10)^2[/tex]
[tex]A_1=100[/tex]
So, area of square base is 100 sq. in.
Area of a triangle is
[tex]A_2=\dfrac{1}{2}\times base\times height[/tex]
[tex]A_2=\dfrac{1}{2}\times 10\times 4[/tex]
[tex]A_2=20[/tex]
So, area of each triangular surface is 20 sq. in.
Now, the total surface area of the pyramid is
Total area = Area of square base + Area of 4 congruent triangles.
[tex]A=A_1+4\times A_2[/tex]
[tex]A=100+4\times 20[/tex]
[tex]A=100+80[/tex]
[tex]A=180[/tex]
Therefore, the area of the pyramid is 180 sq. in.
M is the midpoint if AB . If coordinates of A are (-1,5) and the coordinates of M are (3,3) , what are the coordinates of B?
Answer:
The co-ordinates of B are ( 7,1)
Step-by-step explanation:
Step(i):-
Given that 'M' is the midpoint of AB
Given co-ordinate points are A(-1,5) and midpoint M(3,3)
we know that the midpoint formula
[tex]midpoint = (\frac{x_{1} +x_{2} }{2} ,\frac{y_{1}+y_{2} }{2} )[/tex]
[tex](3,3) = (\frac{-1+x_{2} }{2} ,\frac{5+y_{2} }{2} )[/tex]
Step(ii):-
Equating
[tex]3 = \frac{-1+x_{2} }{2}[/tex] and [tex]\frac{5+y_{2} }{2} = 3[/tex]
cross multiplication, we get
6 = -1 + x₂ and 6 = 5 +y₂
x₂ = 6+1 and y₂ = 6-5
x₂ = 7 and y₂ = 1
Final answer:-
The co-ordinates of B are ( 7,1)
can someone please do this for me and tell me how so I can do the other one pleaseeee I don't know what to do
Answer:
P(green) =1/4
P(orange)=1/2
Step-by-step explanation:
I'm assuming this is probability but it\s been a while, so i'm not sure
number one is a square being divided into half and then one half is being divided into quarters. (as shown by the dotted lines and right angle)
so the probablity of landing in green is 1/4, because it is one fourth of the square.
the probability of the orange is 1/2 because it is 1/2 of the square
The same logic would apply to the "circle" i can see in the next problem. 120 degrees is 1/3 of 360, 90 is 1/4, and so on.
Hope that helps.

Step-by-step explanation:
(7 + x) / 3 = 2x - 5
7 + x = 3(2x - 5) (multiply 3 on both sides)
7 + x = 6x - 15 (distributive property)
5x = 22 (arrange like terms)
x = 4.4 (divide 5 on both sides)

The chemical acidity of a solution is measured in units of pH: pH=-log[H+], where [H+] is the hydrogen ion concentration in the solution. What is [H+] if the pH=8.8?
Answer:
3.5
Step-by-step explanation:
The chemical acidity of a solution is measured in units of pH: pH=-log[H+], where [H+] is the hydrogen ion concentration in the solution. 1.58 x 10⁻⁹ is [H+] if the pH=8.8.
What do you mean by pH ?The term pH is defined as the negative logarithm of the [H+] hydrogen ion.
The isolated hydrogen ion, represented by the symbol H+, hence it is used to represent a proton. Because the bare nucleus can readily combine with other particles like electrons, atoms, and molecules, the hydrogen ion.
The formula for calculating [H+] hydrogen ion is as follows:
pH = - log[H+]
Given pH = 8.8
8.8 = - log[H+]
-8.8 = log[H+]
Taking Antilogarithm Both side
Antilog of [-8.8] = [H ]
By solving above expression [H+]
= 1.58 x 10⁻⁹
Thus, 1.58 x 10⁻⁹ is [H+] if the pH=8.8.

Answer:
? = -36
Step-by-step explanation:
When you raise an exponent to an exponent, the resulting power is a product of the two exponents.
For this problem, you can solve for the missing value by writing:
[tex]?*1/3=-12[/tex]
Divide both sides by 1/3 to isolate the missing value.
[tex]?=\frac{-12}{1/3}[/tex]
Solve for ?.

How many times greater is the area circle 1( radius 12) of than the area circle 2( radius 4) of ?
Answer:
The area of circle 1 is 9 times greater than area of circle 2.
Step-by-step explanation:
Given that:
Radius of circle 1 = 12
Area of circle 1 = πr²
Area of circle 1 = [tex]3.14*(12)^2 = 3.14*144[/tex]
Area of circle 1 = 452.16
Radius of circle 2 = 4
Area of circle 2 = [tex]3.14*(4)^2 = 3.14*16[/tex]
Area of circle 2 = 50.24
Let,
x be the number of times circle 1 is bigger than circle 2.
Area circle 1 = x * Area circle 2
[tex]\frac{452.16}{50.24}=\frac{50.24x}{50.24}\\\\x=9[/tex]
Hence,
The area of circle 1 is 9 times greater than area of circle 2.
