find x in this two examples
The values of x in both figures are 45 and 34, respectively.
The value of x in (a)Start by calculating the angle CAB using:
CAB + ABC + BCA = 180 --- angles in a triangle
The triangle is an isosceles triangle.
So, we have:
CAB + ABC + CAB = 180
Evaluate
2CAB + 25 + 75 = 180
This gives
CAB = 40
Calculate angle BEA using:
BEA + CAB + ABE = 180 --- angles in a triangle
This gives
BEA + 40 + 25 = 180
Evaluate
BEA = 115
Vertical angles are equal.
So, we have:
CED = BEA = 115
Calculate angle EDC using:
EDC + CED + DCE = 180 --- angles in a triangle
This gives
EDC + 115 + 30 = 180
Evaluate
EDC = 35
Opposite angles of quadrilaterals add up to 180.
So, we have:
x + EDC + ABC = 180
This gives
x + 35 + 25 + 75 = 180
Evaluate
x = 45
Hence, the value of x is 45
The value of x in (b)Start by calculating the angle DEC using:
DEC + CDE + EED = 180 --- angles in a triangle
This gives
DEC + 18 + 30 = 180
Evaluate
DEC = 132
Vertical angles are equal.
So, we have:
AEB = DEC = 112
Calculate angle EAB using:
EAB + AEB + ABE = 180 --- angles in a triangle
This gives
EAB + 112 + 42 = 180
Evaluate
EAB = 26
Triangle ABC is an isosceles triangle.
So, we have:
BCE = EAB = 26
Calculate angle CBE using:
CBE + BCE + CEB = 180 --- angles in a triangle
Where CEB = 180 - DEC --- angle on a straight line
So, we have:
CBE + BCE + 180 - DEC = 180
This gives
CBE + 26 + 180 - 112 = 180
Evaluate
CBE = 86
Opposite angles of quadrilaterals add up to 180.
So, we have:
x + EDC + ABC = 180
This gives
x + 18 + 42 + 86 = 180
Evaluate
x = 34
Hence, the value of x is 34

Naomi's car exponentially depreciates at a rate of 8% per
year. If Nina bought the car when it was 4-years old for $16,500, what was
the approximate original price of the car?
The approximate original price of the car is $23032
How to determine the original price?The given parameters are:
Rate, r = 8%
Price at 4 years old = 16,500
An exponential function is represented as:
y = a(1 - r)^x
Where a represents the initial value
This gives
y = a(1 - 8%)^x
Evaluate
y = a(0.92)^x
At 4 years old, we have:
16500 = a(0.92)^4
Divide both sides by (0.92)^4
a = 23032
Hence, the approximate original price of the car is $23032

What is the slope of the line graphed below ? (3, 5); (0, 1); m = A 1/3 B. 3 C. - 3; - 1/3
Answer:
4/3 = m
Step-by-step explanation:
Since you have been given the value of two points, you can use the point-slope formula to find the slope. This general structure of this formula is:
y₁ - y₂ = m(x₁ - x₂)
In this equation, "m" represents the slope, "y₁" and "x₁" represent the values in the first point, and "y₂" and "x₂" represent the values in the second point,
To find the slope, substitute the values of each point into the formula and simplify.
Point 1: (3, 5)
Point 2: (0, 1)
y₁ - y₂ = m(x₁ - x₂) <----- Point-slope form
5 - y₂ = m(3 - x₂) <----- Plug values from Point 1 into equation
5 - 1 = m(3 - 0) <----- Plug values from Point 2 into equation
4 = m(3 - 0) <----- Simplify left side
4 = m(3) <----- Simplify inside the parentheses
4/3 = m <----- Divide both sides by 3

What is the volume of the trash can?
4 7/8 ft³
6 1/4ft³
9 3/4ft³
12 1/2 ft³
Answer:
I think you may have made a typo, as it is extremely unlikely that a trashcan is 314 feet tall. I will assume that you meant 3.14 feet.
Step-by-step explanation:
We already have the base, so we can already cut out one step. If we were not given the base, however, we would simply multiply the length by the width of the prism. Next we multiply the base by the height (3 X 3.14) to get the volume of the prism, 9.42 cubic feet. In the case that there was no typo, and 314 was the correct height, the volume would be 942 cubic feet.

THIS IS ALGEBRA 2 CAN ANYONE SOLVE IT FOR ME?
Answer:
(a) 128 ft
(b) 4 s
(c) Vertex: (1, 144)
Step-by-step explanation:
Given information:
h(t) = height in feett = time in seconds after the launchPart (a)The height of the projectile at launch is the value of h(t) when t = 0 (the y-intercept).
Therefore, from inspection of the graph, the y-intercept is (0, 128).
So the height of the projectile at launch is 128 ft.
Part (b)The length of time it took for the projectile to land is the time from the beginning (when t = 0) to when the height is 0 (the x-intercept).
From inspection of the graph, the x-intercept is (4, 0)
So the length of time it took for the projectile to land is 4 s.
Part (c)The vertex is the turning point (minimum/maximum point).
Therefore, from inspection of the graph, the vertex is (1, 144).
The vertex represents the time and height at which the projectile was at its maximum. So at the time of 1 second, the projectile was at its maximum height of 144 ft.

Using Cavalieri’s Principle, the height of the oblique cylinder with the given volume and base radius is 6cm.
Option A) is the correct answer.
What is the height of the oblique cylinder?From Cavalieri's principle, the volume of an oblique cylinder is expressed as;
V = base area × h
V = πr² × h
Given that;
Radius r = 9cmVolume of the oblique cylinder V = 486πcm³Height of the oblique cylinder h = ?V = πr² × h
486πcm³ = π × ( 9cm )² × h
486πcm³ = π × 81cm² × h
486πcm³ = 81πcm² × h
h = 486πcm³ / 81πcm²
h = 6cm

A jeweler wants to combine a 60% gold alloy with a 20% gold alloy to make 1000 grams of 50% gold alloy. How many grams of 60% alloy should be used?
Answer:
750 grams of 60% alloy
Step-by-step explanation:
Define x = amount of 60% alloy and y = amount of 20% alloy
Equating the amounts of gold:
0.6x+0.2y = 1000(0.5)
Since there must be 1000 grams total:
x+y = 1000
Writing the 2 resulting equations together:
0.6x + 0.2y = 500
x + y = 1000
Multiply the first equation by 5:
3x + y = 2500
x + y = 1000
Subtracting the 2nd equation from the 1st:
2x = 1500
x = 750
Answer: 750 grams of 60% alloy
Solve for x. Round your answer to the nearest tenth if necessary. Figures are not necessarily drawn to scale.

In the third month of a study, a sugar maple tree is 82 inches tall. In the seventh month, the tree is 92 inches tall. Assuming the tree grows at a constant rate every month, what is the rule for the height of the tree during the nth month
The linear equation that gives the height on the x-th month is:
y = 2.5*x + 74.5
Which rule gives the height of the tree for the n-th month?
This will be modeled with a linear equation of the form:
y = a*x + b
Where a is the slope and b is the y-intercept.
Remember that for a line with the points (x₁, y₁) and (x₂, y₂), the slope is given by:
[tex]a = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Here we have the two points (3, 82) and (7, 92). Where the first value is the number of months and the second value is the height.
So the slope is:
[tex]a = \frac{92 - 82}{7 - 3} = 10/4 = 2.5[/tex]
Then the linear equation is:
y = 2.5*x + b
To get the value of b, we use the fact that when x = 3, we have y = 82,
82 = 2.5*3 + b
82 = 7.5 + b
82 - 7.5 = b = 74.5
Then the linear equation is:
y = 2.5*x + 74.5
