Find the missing angle measure.
Need help please!!!
Answer:
This shape is a hexagon. Angles in a hexagon add to 720 degrees.
2(y) + 4(2y-20) = 720
2y + 8y-80 = 720
10y-80=720
10y=800
y=80

For all 4 pics
Answer:
1st pic) 17.8
2nd pic) 16.8
3rd pic) 9.1
4th pic) 13.5
Step-by-step explanation:
1st pic: [tex]cos = \frac{adjacent}{hypothenuse}[/tex]
(write equation) Cos 27 (cos 27 = 0.89) = [tex]\frac{x}{20}[/tex]
(new equation) 0. 89 = [tex]\frac{x}{20}[/tex]
(multiply 20 on both sides) 0.89 x 20 = [tex]\frac{x}{20}[/tex] x 20
(solve) 17.8 = x
2nd pic: [tex]tan = \frac{adjacentx}{hypothenuse}[/tex]
(write equation) tan 40 (tan 40 = 0.84) = [tex]\frac{32}{x}[/tex]
(new equation) 0.84 = [tex]\frac{32}{x}[/tex]
(multiply 32 on both sides) 0.84 x 20 = [tex]\frac{32}{x}[/tex] x 20
(solve) 16.8 = x
3rd pic: [tex]cos = \frac{adjacent}{hypothenuse}[/tex]
(write equation) cos 55 (cos 55 = 0.57) = [tex]\frac{16}{x}[/tex]
(new equation) 0.57 = [tex]\frac{16}{x}[/tex]
(multiply 16 on both sides) 0.57 x 16 = [tex]\frac{16}{x}[/tex] x 16
(solve) 9.1 = x
4th pic: [tex]tan = \frac{adjacentx}{hypothenuse}[/tex]
(write eqaution) tan 42 (tan 42 = 0.90) = [tex]\frac{x}{15}[/tex]
(new equation) 0.90 = [tex]\frac{x}{15}[/tex]
(multiply 15 on both sides) 0.90 x 15 = [tex]\frac{x}{15}[/tex] x 15
(solve) 13.5 = x

This composite figure is created by placing a sector of a circle on a rectangle. What is the area of this
composite figure? Use 3.14 for it. Show all calculations that lead to the answer and include units. Please provide steps to prove your answer.
Answer:
148.12m²
Step-by-step explanation:
At first, lets find the area of rectangle.
length = 14m
breadth = 6m
Area of rectangle = length x breadth
= 14 x 6
= 84m²
Now, For the area of sector of the circle,
Given angle (a) = 34
radius = 14m
Area of the sector = a / 360 x pi x r²
= 34/360 x 3.14 x 14²
= 34 / 360 x 3.14 x 196
= 58.12m²
Now adding both areas,
84 + 58.12 = 142.12m²
Segment of a circle is the part of the circle. The total area of the composite figure is 142.1544 m².
What is the area of the segment of a circle?The area of the segment of the circle is given by the formula,
[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]
As it is given that the composite figure is made up of a circular segment and a rectangle, therefore, we will find the area of the rectangle and the area of the circular segment individually.
Area of the rectangle
The area of the rectangle is the product of its length and breadth, therefore, the area is,
[tex]\rm \text{Area of the rectangle} = Length \times breadth[/tex]
[tex]= 14 \times 6\\\\=84\rm\ m^2[/tex]
Area of the sector of the circle
[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]
[tex]= \pi \times 14^2 \times \dfrac{34}{360}\\\\=58.1544\rm\ m^2[/tex]
The total area of the composite figure
The total area of the composite figure
= Area of rectangle + Area of the segment of the circle
= 84 + 58.1544 m²
= 142.1544 m²
Hence, the total area of the composite figure is 142.1544 m².

the straight line L, has equation y=3x-4 The straight line 1, in perpendicular to L, and passes through the point (9.5) Find an equation of line L
Given:
The equation of given line is
[tex]y=3x-4[/tex]
A line is perpendicular to the given line and passes through the point (9,5).
To find:
The equation of the perpendicular line.
Solution:
We have,
[tex]y=3x-4[/tex]
On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get
[tex]m=3[/tex]
It means, the slope of the given line is 3.
The product of slopes of two perpendicular lines is -1.
[tex]m\times m_1=-1[/tex]
[tex]3\times m_1=-1[/tex]
[tex]m_1=-\dfrac{1}{3}[/tex]
Point slope form of a line is
[tex]y-y_1=m(x-x_1)[/tex]
Where, m is the slope.
The slope of perpendicular line is [tex]-\dfrac{1}{3}[/tex] and it passes through the point (9,5). So the equation of the line is
[tex]y-5=-\dfrac{1}{3}(x-9)[/tex]
[tex]y-5=-\dfrac{1}{3}(x)-\dfrac{1}{3}(-9)[/tex]
[tex]y-5=-\dfrac{1}{3}x+3[/tex]
Adding 5 on both sides, we get
[tex]y-5+5=-\dfrac{1}{3}x+3+5[/tex]
[tex]y=-\dfrac{1}{3}x+8[/tex]
Therefore, the equation of required line is [tex]y=-\dfrac{1}{3}x+8[/tex].
What function is graphed below?
Y=x/3
Y=2 x +3
Y= 2 x + 3
Y = 3x
Answer: its y=x/3
So x/3 is the slope and means the same as 1/3 x
the 1/3 shows we go up one and over 3 because slope is y/x

I need help on 1, 2, an 3
Answer: 1. A) 2/5 B) X= -5 Y= 2
2. A) -3/2 B) X= 2 Y= 3
3. A) -2/3 B) X= -3 Y= -2
Step-by-step explanation: A) Look where the line intersects perfectly through a corner of one of the boxes, find the next one closes to that count how many it goes up and how many across. Rise/Run so the amount it goes up goes on the top of the fraction and the amount across on the bottom of the fraction.
B) This is where the line intersects the X and Y axis

m∠CED = 1/2(mCD + mBU)125° = 1/2(195° + mBU)195° + mBU = 250°mBU = 250° - 195°mBU = 55°Working together, Beth and Katy can wash a car in 6 minutes. Had she done it by herself, it would have taken Katy 18 minutes. How long would it take Beth to wash the car herself?
Answer:
It would take Beth twelve minutes to wash the car herself
Step-by-step explanation:
If they do it together in 6 minutes.
& Katy can do it in 18 minutes alone
Then 18 - x = 6
replace x for twelve
18 - twelve = 6

GUYS PLEASE HELP ASAP!!!!!!! A car is driving 18 meters per second. It then merges on to a highway and accelerates at a rate of 6 meters per second per second for 2.0 seconds. It then remains at this speed. What is the speed of the car on the highway?
a. 3.0 m/s
b. 12.0 m/s
c. 26.0 m/s
d. 30 m/s
Answer:
it is going to be B. 10 m/s
The speed of the car on the highway will be 30 m/s
What is acceleration?The rate at which velocity changes with time, in terms of both speed and direction.
Given that, a car is driving 18 meters per second. It then merges on to a highway and accelerates at a rate of 6 meters per second for 2.0 seconds.
Using first equation of motion,
v = u + at where, v is final velocity, u is initial velocity, a is acceleration and t is time,
v = 18 + 6*2
v = 18 + 12
v = 30
Hence, speed of the car on the highway will be 30 m/s

A sequence can be generated by using an = 4a(n - 1)) where a= 6 and n is a whole
number greater than 1. What are the first four terms in the sequence?
Given:
The sequence can be generated by
[tex]a_n=4a_{(n - 1)}[/tex]
Where [tex]a_1= 6[/tex] and [tex]n[/tex] is a whole number greater than 1.
To find:
The first four terms of the given sequence.
Solution:
We have,
[tex]a_n=4a_{(n - 1)}[/tex] ...(i)
It is given that [tex]a_1= 6[/tex]. So, for [tex]n=2[/tex], we get
[tex]a_2=4a_{(2 - 1)}[/tex]
[tex]a_2=4a_1[/tex]
[tex]a_2=4(6)[/tex]
[tex]a_2=24[/tex]
Putting [tex]n=3[/tex] in (i), we get
[tex]a_3=4a_{(3- 1)}[/tex]
[tex]a_3=4a_2[/tex]
[tex]a_3=4(24)[/tex]
[tex]a_3=96[/tex]
Putting [tex]n=4[/tex] in (i), we get
[tex]a_4=4a_{(4- 1)}[/tex]
[tex]a_4=4a_3[/tex]
[tex]a_4=4(96)[/tex]
[tex]a_4=384[/tex]
The first four terms of the given sequence are 6, 24, 96,384.
Therefore, the correct option is C.

Viola drives 2 kilometers up a hill that makes an angle of 4 degrees with the horizontal. To the nearest tenth of a kilometer, what horizontal distance has she covered
Answer:
2.0 km
Step-by-step explanation:
From the diagram attached,
cosθ = adjacent/Hypotenus
cos4° = x/2
make x the subject of the equation
x = 2cos4°
x = 2(0.998)
x = 1.995
x = 2.0 km. (to the nearest tenth)
Hence the horizontal distance is 2.0 km
