the measure of ∠ABD is (0.18x+54)° and the measure of ∠CBD is (0.07x+39)°. find the value of x.
Answer:
x = 348
Step-by-step explanation:
From the given we can tell it a supplementary angle.
Don't know what supplementary angle is?
Supplementary angle are angles that :
Equal 180 °
Solve:
Since,
∠ABD is (0.18x+54)°
∠CBD is (0.07x+39)°
Thus,
(0.18x+54) + 0.07x + 39 = 180
Group likes terms:
0.25x + 54 + 39 = 180
0.25 + 93 = 180
Subtract 93 from both sides
0.25x = 87
x = 348
Check Answer:
0.18(348) + 54 + 0.07(348) + 39
= 180

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions:
y < 4x − 8
y is greater than or equal to negative 5 over 2 times x plus 5
Part A: Describe the graph of the system, including shading and the types of lines graphed. Provide a description of the solution area.
Part B: Is the point (5, −8) included in the solution area for the system? Justify your answer mathematically.
< sign so it's dotted line to be graphed .
Put (0,0)
0<0-80>-8Away from origin shading
And
y≥-5/2x+5Put 0
0≥-5/5=-1Rational function ,two side parabola type lines
Dark lines and it's shading from origin in one part and in other towards origin(Look attachment)
Graph attached
Yes (5,8) is included in solution region
Answer:
Given inequalities:
[tex]y < 4x-8[/tex]
[tex]y\geq -\dfrac{5}{2}x+5[/tex]
Part AThe graph of the system is made up of 2 straight line graphs.
The graph of [tex]y < 4x-8[/tex] is a dashed straight line with shading under the line.
The graph of [tex]y\geq -\dfrac{5}{2}x+5[/tex] is a solid straight line with shading above the line.
The solution area is the area where the shading of the two lines overlaps.
Part BTo determine if the point (5, -8) is included in the solution area, input the point into both inequalities:
[tex]\begin{aligned}y & < 4x-8\\\implies -8 & < 4(5)-8\\-8 & < 20-8\\-8 & < 12 \quad \leftarrow \textsf{correct}\end{aligned}[/tex]
[tex]\begin{aligned}y & \geq -\dfrac{5}{2}x+5\\\implies -8 & \geq -\dfrac{5}{2}(5)+5\\\implies -8 & \geq -7.5 \quad \leftarrow \textsf{incorrect}\end{aligned}[/tex]
Therefore, the point (5, -8) is not included in the solution area as it is only true for one inequality.

The graph of f(x) satisfies the conditions lim f(x) = -4 and lim f(x) = 0 is the graph attached.
What is one-sided limit for function?It should be noted that the limit from one side is simply when the side of the functions is used with respect to the point of interest.
For this graph, the point x = 2 on the left from the point x = 2 lies a ray. The prediction here is that the value of function on x = 2 us the value that the line gives for y.
Therefore, the graph of f(x) satisfies the conditions lim f(x) = -4 and lim f(x) = 0 is attached.

Suppose you toss 10 coins randomly at the board below and that all coins stay on the board. Find the probability as a fraction of landing in the shaded region.
A. 1/9
B. 8/9
C. 2/3
Answer: B
Step-by-step explanation:
The area of the larger square is 9^2 = 81, and the area of the smaller square is 3^2 = 9. This means the area of the shaded region is 81-9=72. Hence, the desired probability is 72/81 = 8/9.

Jada recorded the heights of the plants she's growing in her garden. This line plot shows what she recorded.
How much taller is one of the tallest plants than one of the shortest plants?
The tallest plant is [tex]1 \dfrac{3}{4}\ inches[/tex] timed taller than the shortest plant.
What is graphical analysis?The finding of the conclusion by reading the data on the graph is termed as the graphical analysis.
Given:
The line plot below shows the heights of flowers in a garden.
To Find:
How much taller is the tallest flower than the shortest flower?
The solution will be:
Knowing that each dot represents it's heights.
Let's makes a table:
[tex]6 \dfrac{1}{2} =OO[/tex]
[tex]6 \dfrac{3}{4} = O[/tex]
7 ⇒ ОООО
[tex]7 \dfrac{1}{4} == > OOOOOO[/tex]
[tex]7 \dfrac{1}{2} = OOOO[/tex]
[tex]7 \dfrac{3}{4} = OO[/tex]
8 ⇒ none
[tex]8 \dfrac{ 1}{4} = O[/tex]
[tex]8 \dfrac{1}{2}[/tex] ⇒ none
It's also given that the tallest flower and the shortest flower.
Which is:
Smallest → [tex]6 \dfrac{1}{2}[/tex]
Tallest → [tex]8 \dfrac{1}{4}[/tex]
Now all we have to do is subtract tallest flower from the shortest flower.
[tex]8 \dfrac{ 1}{4} - 6\dfrac{ 1}{2}[/tex]
Break off 1 from 8 : 8 1/4 = 7 5/4
Now we have:
[tex]7 \dfrac{5}{4} - 6\dfrac{ 1}{2}[/tex]
Subtract whole number: 7 - 6 = 1
Combine fraction:
[tex]\dfrac{5}{4} - \dfrac{1}{2} = \dfrac{3}{4}[/tex]
[tex]=1 + \dfrac{3}{4}[/tex]
Hence the tallest plant is [tex]1 \dfrac{3}{4}\ inches[/tex] timed taller than the shortest plant.

Answer:
7776π in³
Step-by-step explanation:
You are given the area of the sphere, so you can use the area formula to find its radius. Then the volume formula can be used to find the volume.
__
radiusThe area of the sphere is given by the formula ...
A = 4πr²
Solving for r, we find ...
A/(4π) = r²
√(A/(4π)) = r = √(1296π/(4π)) = √324 = 18
The radius of the sphere is 18 inches.
__
volumeThe volume formula is ...
V = 4/3πr³
Using the found radius, we find the volume to be ...
V = 4/3π(18 in)³ = 4/3(5832)π in³
V = 7776π in³

What is the missing angle? (Please use image attached)
Answer:
56
Step-by-step explanation:
Since vertical angles are equal, we know the two angles labeled are equal.
We can then set up an equation to get
[tex]19x-28=9x+52.[/tex]
Subtracting [tex]9x[/tex] from both sides to isolate the variable gives us
[tex]10x-28=52[/tex].
Then, adding [tex]28[/tex] to both sides gives
[tex]10x=80,[/tex]
and dividing both sides by 10 gives
[tex]x=8.[/tex]
Now, we can find the measure of [tex]9x+52[/tex] by plugging what we found for [tex]x[/tex] in:
[tex]9(x)+52=9(8)+52=72+52=124.[/tex]
Since the angles ? and 9x+52 make up a line, they are supplementary. Therefore, we have
[tex]?=180-(9x+52)=180-124=\boxed{56}.[/tex]
