Answer:
a= 50
b=50
c=110
d=20
Answer:
Step-by-step explanation:
This is a kite. So the two triangles formed by the longest diagonal being drawn in form 2 congruent triangles.
Therefore c = 110 degrees.
d = 20 degrees.
a and b are found by noting that every triangle has 180 degrees.
110 + 20 + a = 180 Combine the left.
130 + a = 180 Subtract 130 from both sides
a = 180 - 130
a = 50 degrees
b also equals 50 degrees. Congruent triangles
Answer
a = 50b = 50c = 110d = 20Related Questions

Answer:
[tex]\frac{4}{5}[/tex] (4/5)
just fill out 4 in the blank
Step-by-step explanation:
1. Equal the denominator for 1/4
End result=[tex]\frac{11}{20}[/tex]
So all the other ones have to be made according to this
20/4=5
1x5=5
[tex]\frac{1}{4}[/tex] will now be [tex]\frac{5}{20}[/tex]
2. Figure out what ?/5 will be
If this number is getting subtracted by [tex]\frac{5}{20}[/tex] then, we have to add [tex]\frac{11}{20}[/tex] by [tex]\frac{5}{20}[/tex] to get our answer.
[tex]\frac{11}{20} +\frac{5}{20} =\frac{16}{20}[/tex]
this means that when [tex]\frac{16}{20}[/tex] gets subtracted by [tex]\frac{5}{20}[/tex] it will equal [tex]\frac{11}{20}[/tex]
3. Simplify 16/20 to it's lowest terms
5x4=20
20/5=4
so, each part ([tex]\frac{1}{5}[/tex]) worth's 4
20-4=16
So that means, that the simplest for for this is [tex]\frac{4}{5}[/tex]
So hence, your answer is 4/5just fill out 4 in the blank

Answer:

Step-by-step explanation:
Let the blank = x
Thus,
[tex]\frac{x}{5}-\frac{1}{4}=\frac{11}{20}[/tex]
[tex]\mathrm{Add\:}\frac{1}{4}\mathrm{\:to\:both\:sides}[/tex]
[tex]\frac{x}{5}-\frac{1}{4}+\frac{1}{4}=\frac{11}{20}+\frac{1}{4}[/tex]
[tex]\mathrm{simplify}[/tex]
[tex]\frac{x}{5}=\frac{4}{5}[/tex]
[tex]\mathrm{Multiply\:both\:sides\:by\:}5[/tex]
[tex]\frac{5x}{5}=\frac{4\cdot \:5}{5}[/tex]

Find the distance between (1, 1) and (3, 4).
Answers
Answer:
√13
Step-by-step explanation:
Let,
( x1, y1 ) = ( 1, 1 )
Here,
x1 = y1 = 1
( x2, y2 ) = ( 3, 4 )
Here,
x2 = 3
y2 = 4
Formula : -
( Distance )² = ( x2 - x1 )² + ( y2 - y1 )²
( Distance )² = ( 3 - 1 )² + ( 4 - 1 )²
= 2² + 3²
= 4 + 9
( Distance )² = 13
Distance = √13

For a project in her Geometry class, Naomi uses a mirror on the ground to measure
the height of her school building. She walks a distance of 12.25 meters from the
school, then places a mirror on flat on the ground, marked with an X at the center.
She then steps 1.7 meters to the other side of the mirror, until she can see the top of
the school clearly marked in the X. Her partner measures the distance from her eyes
to the ground to be 1.15 meters. How tall is the school? Round your answer to the
nearest hundredth of a meter.
Answers
Answer:
8.28
Step-by-step explanation:
we can express this question as
12.25/1.7=x/1.15
this can be simplified to
x=8.28
The height of Naomi's school building is 8.29 meters
Concept of similar triangles:
Two triangles are similar if their corresponding angles are equal and their corresponding sides are within the same ratio (or proportion). Similar triangles will have the same shape, but not necessarily the same size.
In the given question and attached figure we have,
BC = 12.25 metersCD = 1.7 metersDE = 1.15 metersNow we have to find the height(AB) of the building,
By the properties of similar triangles, we can write,
AB / BC = DE / CD
Putting all the values we get,
AB / 12.25 = 1.15 / 1.7
Simplifying we get,
AB = (1.15 / 1.7) × 12.25
By further simplifying,
AB = 8.29 meters
Therefore, the height of Naomi's school building is 8.29 meters.

what
arithmetic sequence with a_{4}=18 and a_{10}=48
Answers
Answer:
[tex]a_{n}[/tex] = 5n - 2
Step-by-step explanation:
the nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
given a₄ = 18 and a₁₀ = 48 , then
a₁ + 3d = 18 → (1)
a₁ + 9d = 48 → (2)
subtract (1) from (2) term by term to eliminate a₁
6d = 30 ( divide both sides by 6 )
d = 5
substitute d = 5 into (1) and solve for a₁
a₁ + 3(5) = 18
a₁ + 15 = 18 ( subtract 15 from both sides )
a₁ = 3
Then
[tex]a_{n}[/tex] = 3 + 5(n - 1) = 3 + 5n - 5 = 5n - 2

What are the coordinates of the vertex of the function f(x)=x2 10x−3?
Answers
Answer:
A. (-5, -28)
Step-by-step explanation:
The coordinates of the vertex of the function [tex]\rm f(x) = x^2+10x-3[/tex] is
(-5, -28).
It is given that the function [tex]\rm f(x) = x^2+10x-3[/tex]
It is required to find the coordinates of the vertex.
What is a parabola?It is defined as the graph of a quadratic function that has something bowl-shaped.
We have a function:
[tex]\rm f(x) = x^2+10x-3[/tex]
This function represents a parabola.
We know the standard form of parabola in quadratic style:
[tex]\rm f(x)=ax^2+bx+c[/tex]
By comparing the given function to the standard form of parabola, we get
a = 1, b = 10, and c = -3
The vertex of the parabola is given by:
[tex]\rm x = -\frac{b}{2a}[/tex]
Putting the values in the above equation, we get:
[tex]\rm x = -\frac{10}{2\times1} \Rightarrow -5[/tex]
x = -5 put this value in the given parabola function, we get:
[tex]\rm f(-5) = (-5)^2+10(-5)-3\\\rm f(-5) = 25-50-3\\\rm f(-5) = -28[/tex]
or y = -28
The coordintes = (x, y) : (-5 , -28) which is shown in the graph.
Thus, the coordinates of the vertex of the function [tex]\rm f(x) = x^2+10x-3[/tex] is (-5, -28).

One box measures 2 feet by 1 foot by 1 foot a larger box measures 2feet by 2 1/2 feet by 2 how many times larger is the volume of the larger box then the smaller box
Answers
The number of times the larger box is bigger than the smaller box is 5.
How many times larger is the larger box?The first step is to determine the volume of both boxes.
Volume = length x width x height
Volume of the larger box = 2 x 2 1/2 x 2 = 10ft³
Volume of the smaller box = 2 x 1 x 1 = 2 ft³
Now divide the Volume of the larger box by the volume of the smaller box : 10 / 2 = 5

Answers
To attempt this algebraic equation we will be multiplying 4 to (3 - x) bracket so as to form the term on L.H.S.
[tex]:\implies\tt{4(3 - x) = (1 - 2x)}[/tex]
[tex]:\implies\tt{(12 - 4x) = (1 - 2x)}[/tex]
[tex]:\implies\tt{12 - 4x = 1 - 2x}[/tex]
Combining like terms, we get,
[tex]:\implies\tt{12 - 1 = - 2x + 4x}[/tex]
[tex]:\implies\tt{11 = 2x}[/tex]
[tex]:\implies\tt{2x = 11}[/tex]
[tex]:\implies\tt{x = \frac{11}{2} }[/tex]
[tex]:\implies\tt{x = 5.5}[/tex]
The value of x is 5.5Hey there!
4(3 - x) = (1 - 2x)
4(3) + 4(-x) = 1 - 2x
12 - 4x = 1 - 2x
-4x + 12 = -2x + 1
ADD 2x to BOTH SIDES
-4x + 12 + 2x = -2x + 1 + 2x
SIMPLIFY IT!
-2x + 12 = 1
SUBTRACT 12 to BOTH SIDES
-2x + 12 - 12 = 1 - 12

-2x = -11
DIVIDE -2 to BOTH SIDES
-2x/-2 = -11/-2

students were grouped into 4 classrooms with an average of 33.5 students per classroom. if the students were regrouped into 5 classrooms, what would be the average number of students in each room?
Answers
Answer:
26.8
Step-by-step explanation:
Because 33.5 was the average of how many students were in a classroom (if there were 4 classrooms), then 33.5 is can somewhat be the average of how many students were in one classroom; 1/4 of the classrooms can hold an average of 33.5.
Total students that were divided into 4 classrooms :
33.5 × 4 = 134
So if there is 134 students that will be grouped into 5 different classrooms, divide 134 by 5 to find the average amount of students that will be grouped.
134 ÷ 5 = 26.8
So, the average amount of students that will be grouped if they were divided into 5 classrooms would be 26.8 .
