Find the perimeter of the figure
Answer:
142
Step-by-step explanation:
Ok explanation
we know the sides 9, 11, 38, and 13.
there are 2 missing sides we need to find
so the first one whic is the longer one is we know that the 38 is already 1 part of it but not the whole thing. We know the 9 is part of the 38 since it connects. So that gives us that side of 47.
Now for the shrter side, we know 1 part of it is 13 And the other part is 11. So we Add them up and get 24
Now the sides are 9, 11, 38, 13, 47, and 24
We add them up and get 142
Answer:
142 mi
Step-by-step explanation:
Top = 9 +38 = 47
Right Side = 13
Bottom Right = 38
11 + 9 = 20
Left Side = 24
47 + 13 +38 + 20 + 24 = 142

Answer:
The value of x = -10 if g(x)=0.
i.e.
When x = 0, g(-10)=0
Step-by-step explanation:
From the given graph, it is clear that the graph passes through the x-axis when x = -10.
In other words, the function becomes zero at x = -10.
Thus, the x-intercept x = -10 will determine that:
at x = -10 , g(-10) = 0
Thus, the value of x = -10 if g(x)=0.
i.e.
When x = 0, g(-10)=0

1. The main show tank has a radius of 70 feet and forms a quarter sphere where the bottom of the pool is spherical and the top of the pool is flat. (Imagine cutting a sphere in half vertically and then cutting it in half horizontally.) What is the volume of the quarter-sphere shaped tank? Round your answer to the nearest whole number. You must explain your answer using words, and you must show all work and calculations to receive credit.
2. The holding tanks are congruent. Each is in the shape of a cylinder that has been cut in half vertically. The bottom of each tank is a curved surface and the top of the pool is a flat surface. What is the volume of both tanks if the radius of tank #1 is 35 feet and the height of tank #2 is 120 feet? You must explain your answer using words, and you must show all work and calculations to receive credit.
3. The company is building a scale model of the theater’s main show tank for an investor's presentation. Each dimension will be made one sixth of the original dimension to accommodate the mock-up in the presentation room. What is the volume of the smaller mock-up tank?
Using the information from #3, answer the following question by filling in the blank: The volume of the original main show tank is ____% of the mock-up of the tank.
Answer:
1. Volume = 5128.67 ft³
The volume if sphere is given by:
V = (4/3)πr³
If the tank is cut into half vertically, then the volume of sphere becomes.
V = (4/3)πr³ / 2
If the tank is cut into half again horizontally, then the volume of the sphere becomes.
V = (4/3)πr³ / 4
Hence, as the main tank forms a quarter sphere, its Volume is given by:
V = (4/3)πr³ / 4
It is given in the question that the radius is 70 ft.
Substitute that in the given formula:
V = (4/3)π(70)³ / 4
V = 5128.67 ft³
2. Volume of tank = 461,814 ft³
Step-by-step explanation:
Congruent tanks implies that both tanks are of identifical shape, form & dimensions. Congruent means that the tanks have the same radius as well as height. Hence, the heights and radii of tanks #1 and #2 are equal and the same.
Let's list out the information given us:
radius(tank #1) = 35 ft ⇒ radius(tank #2) = 35 ft, height(tank #2) = 120 ft ⇒ height(tank #2) = 120 ft
Volume of cylinder = πr²h
The tanks have been cut into half, as such:
Volume of tank = ½πr²h
Volume of tank = Volume(tank #1) + Volume(tank #2)
Since the tanks are congruent (same dimensions), we have:
⇒ ½πr²h + ½πr²h ⇒ πr²h
Volume of tank = π * 35² * 120 = 147,000 π
Volume of tank = 461,814 ft³
3. 1047.2 ft³
Step-by-step explanation:
The following information is missing:
The main show tank has a radius of 60 feet and forms a quarter sphere where the bottom of the pool is spherical and the top of the pool is flat. (Imagine cutting a sphere in half vertically and then cutting it in half horizontally)
The only dimension needed for the main show tank is its radius. Then the model radius will be 1/6 * 60 = 10 feet
The volume of a sphere is:
V = 4/3 * π * r³
For a quarter sphere it is:
V = 4/3 * π * r³ * 1/4
V = 1/3 * π * r³
For the smaller mock-up tank:
V = 1/3 * π * 10³
V = 1047.2 ft³

Answer:
[tex] \frac{ - 2}{25} \times 5[/tex]
first you multiply 2 by 5. Then you get 10 over 25. Then you simplify it. What is the common factor of both 10 and 25? Is it 2? No 2 is a factor of 10 but not 25. It's 5. After you get the common factor you divide both numbers by it. So 10/5 would be 2. 25 divide by 5 would be 5. And the negative sign remains
-2/25 x 5/1 = -10/25 = -2/5

In the figure below, what is the value of x
Answer:
x = 49°
Step-by-step explanation:
Angles in a Triangle
The sum of the internal angles in any triangle adds up to 180°.
The figure shows a triangle that includes two angles with the same tick mark. This means they are congruent, i.e. they measure the same.
The larger triangle has three defined angles: 43°, 39°, and 2x. Since the sum of them is 180°:
43° + 39° + 2x = 180°
Operating:
82° + 2x = 180°
Subtracting 82°:
2x = 180° - 82° = 98°
x = 98°/2 = 49°
x = 49°

x=[-4+\-√36]/2
x=[-4+\-6]/2
x=(-4+6)/2 ,x=(-4-6)/2
x=2/2 , x=-10/2
x=1 , x=-5
The number of solutions to the equation are two and Real in nature. The solutions are x = 1 and x = - 5.
We have the following quadratic equation -
x + [tex]2x^{2}[/tex] - 4 = -7x + 6
We have to determine its solutions.
What is the Quadratic formula to find the roots of a quadratic equation ?The Quadratic formula is -
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
According to question, we have -
x + [tex]2x^{2}[/tex] - 4 = -7x + 6
Rearranging the equation -
[tex]2x^{2}[/tex] + x + 7x - 4 - 6 = 0
[tex]2x^{2}[/tex] + 8x - 10 = 0
Using the quadratic formula -
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
[tex]$x=\frac{-8\pm\sqrt{64-(-80)}}{4}$[/tex]
[tex]$x=\frac{-8\pm\sqrt{144}}{4}$[/tex]
[tex]$x=\frac{-8 +12}{4}[/tex] and [tex]$x= \frac{-8-12}{4}[/tex]
x = 1 and x = - 5
Hence, the number of solutions to the equation are two and Real in nature. The solutions are x = 1 and x = - 5.

Equation of a Straight Line
2.2 Solve 2x+y-285 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 2x+y-285 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 285/1 so this line "cuts" the y axis at y=285.00000
y-intercept = 285/1 = 285.00000
Calculate the X-Intercept :
When y = 0 the value of x is 285/2 Our line therefore "cuts" the x axis at x=142.50000
x-intercept = 285/2 = 142.50000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 285.000 and for x=2.000, the value of y is 281.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 281.000 - 285.000 = -4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = -4.000/2.000 = -2.000
Geometric figure: Straight Line
Slope = -4.000/2.000 = -2.000
x-intercept = 285/2 = 142.50000
y-intercept = 285/1 = 285.00000

Answer:
x = 3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
17 - (3x + 5) = 3x - 6
Step 2: Solve for x
Distribute negative: 17 - 3x - 5 = 3x - 6Add 3x on both sides: 17 - 5 = 6x - 6Combine like terms: 12 = 6x - 6Isolate x term: 18 = 6xIsolate x: 3 = xRewrite: x = 3Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 17 - (3(3) + 5) = 3(3) - 6Multiply: 17 - (9 + 5) = 9 - 6Add: 17 - 14 = 9 - 6Subtract: 3 = 3Here we see that 3 does indeed equal 3.
∴ x = 3 is the solution to the equation.
Answer:
x = 3
Step-by-step explanation:
17 - 1(3x + 5) = 3x - 6
17 − 3 − 5 = 3x − 6
12 - 3x = 3x - 6 subtract five
-3x + 12 = 3x - 6 rearrange terms
