Answer:
x= 32
Step-by-step explanation:
3x-2+3x-10= 180 (sum of angles in straight line)
6x-12=180
6x=192
6x/6= 192/ 6
x = 32
Step-by-step explanation:
3x - 2 ° + 3x - 10° = 180°
reason : being angle in linear pair ...
6x - 12 = 180°
6x = 180° + 12
6x = 192°
[tex] x = \frac{192}{6} \\ [/tex]
x = 32°
Now ,
3x - 2 °
= 3 × 32 - 2
= 96 - 2
= 94°
Again ,
= 3x - 10°
= 3 × 32 - 10°

The circumference of the given circle is: 16πcm.
What is a circle?All points in a plane that are at a specific distance from a specific point, the center, form a circle. In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.
Given: Area of a circle = 64π cm²
To find: Circumference of the circle.
Finding:
We know that the formula of the area of a circle = πr²,
On comparing it with the given value, we get:
πr² = π(64)
πr² = π(8)²
8² = r²
r = 8cm (as the side of a circle can never be negative).
Also, the formula of the circumference of a circle = 2πr
Thus, for the circle having radius 8 cm, circumference = 2π(8) = 16πcm.
Hence, The circumference of the given circle is: 16πcm.

Triangle ABC has the following angle measures:
m∠A = (2x − 24)°, m∠B = (x + 8)°, m∠C = (4x + 49)°
What is m∠A?
pleaseee help
The measure of angle A in the triangle is 18°
How to determine the measure of angle A?The angles in the triangle are given as:
m∠A = (2x − 24)°, m∠B = (x + 8)°, m∠C = (4x + 49)°
The sum of angles in a triangle is 180
So, we have
m∠A + m∠B + m∠C = 180
Substitute the known values in the above equation
So, we have:
2x − 24 + x + 8 + 4x + 49 = 180
Evaluate the like terms
7x = 147
Divide both sides by 7
x = 21
Substitute x = 21 in m∠A = (2x − 24)°
m∠A = (2 * 21 − 24)°
Evaluate
m∠A = 18°
Hence, the measure of angle A in the triangle is 18°

Louis sets off a firework. The height of the firework at the time t seconds is given by h (t) 16t^2+128t.
Use the quadratic formula to estimate when into the trip the rocket is 64 feet high.
A
at about 0.4 seconds and about 7.6 seconds
B
at about 0.8 second and about 5.2 seconds
C
at about 1.1 seconds and about 6.8 seconds
D
at about 0.5 seconds and about 7.5 seconds
The option D is correct that is at about 0.5 seconds and about 7.5 seconds the firework will be at height 64 feet.
What is a quadratic equation ?
A quadratic equation is an equation which contains a single variable of degree 2 and its general form is ax² + bx + c = 0.
The height of firework is represented by a quadratic equation which is 16t² + 128t.
Let's find out that at what time the rocket will be at height of 64 feet.
So,
16t² + 128t = 64 feet
or
16t² + 128t - 64 = 0
or
t² + 8t - 4 = 0
We know that quadratic equation is in form ax² + bx + c = 0.
Using the quadratic formula to find value of t :
[tex]t=\frac{-b\pm\sqrt{b^2-4ac}}{2a}.[/tex]
t = [ -8 ± √(8² - (4 × 1 × - 4))] / ( 2 × 1 )
t = [ - 8 ± 8.94 ] / 2
t = -4 ± 4.47
So , the value of t can be either -4 + 4.47 or -4 - 4.47 which is equal to 0.47 or - 8.47 seconds. Time can't be negative , so t = 0.47 or 0.5 seconds.
Therefore , the option D is correct that is at about 0.5 seconds and about 7.5 seconds the firework will be at height 64 feet.

A gold mine has two elevators, one for equipment and another for the miners. The equipment elevator
descends 6 feet per second. The elevator for the miners descends 15 feet per second. One day, the equipment elevator begins to descend. After 33 seconds, the elevator for the miners begins to descend. What is the position of each elevator relative to the surface after another 12 seconds? At that time, which elevator is deeper?
i. The equipment elevator is at a depth of 270 feet (-270 feet), while the miners elevator is at a depth of 180 feet (-180 feet) below the surface.
ii. The equipment elevator is deeper than that of the miners elevator.
The speed of an object is the rate at which the object moves.
speed = distance / time.
Thus,
Speed of the equipment elevator = 6 feet per second
Speed of the miners elevator = 15 feet per second.
Time of descent of the equipment elevator = 33 + 12
= 45 seconds
So that, the distance of the elevator at this time is;
⇒ distance = speed x time
= 6 x 45
= 270 feet
distance = - 270 feet
The distance of the miners elevator after 12 seconds is:
⇒ distance = speed x time
= 15 x 12
= 180 feet
distance = - 180 feet
Thus after another 12 seconds, the equipment elevator is at a depth of 270 feet (-270 feet), while the miners elevator is at a depth of 180 feet (-180 feet) below the surface.
Therefore, the equipment elevator is deeper than that of the miners elevator.

89 degrees
Step-by-step explanation:Triangles will always have 180 degrees. This means that given 2 angles, we can find the missing measurement.
Setting Up an Equation
To help us solve for the unknown angle, a, we can set up an algebraic equation. To make this equation remember that all 3 internal angles sum to 180.
14 + 77 + a = 180This is only one equation that you could set up to represent this situation.
Solving For a
Now that we have an equation we can begin to solve it. First, combine like terms that are on the same side of the equation.
91 + a = 180Next, subtract 91 from both sides.
a = 89To check our answer we can plug it back into the original equation.
14 + 77 + 89 = 180180 = 180This means that the missing angle must be 89 degrees.

Step-by-step explanation:
Since the pH has to be between 7.2 and 7.8, it is more than 7.2 and less than 7.8.
The less than equal to sign was used because the pH can also equal 7.2 and 7.8.
Like mentioned, any variable like x can be used instead of the "pH" I put in the equation, but make sure to define your variable.

How to use the drawing tool(s) to form the correct answer on the provided graph?The function is given as
h(x) =(x - 1)^2 - 9
The x-intercept
Set h(x) to 0
So, we have
(x - 1)^2 - 9 = 0
Add 9 to both sides
(x - 1)^2 = 9
Take the square root of both sides
x - 1 = ±3
This gives
x = 1 ± 3
Expand
x = (1 - 3, 1 + 3)
Evaluate
x = (-2, 4)
Hence, the x-intercepts are x =2 and x = 4
The y-intercept
Set x to 0
So, we have
h(0) = (0 - 1)^2 - 9
Evaluate
h(0) = -8
Hence, the y-intercept is h(x) =-8
The vertex
We have
h(x) =(x - 1)^2 - 9
Expand
h(x) = x^2 - 2x + 1 - 9
Differentiate
h'(x) = 2x - 2
Set to 0 and solve for x
2x - 2 = 0
This gives
x = 1 --- this represents the axis of symmetry
Substitute x = 1 in h(x) =(x - 1)^2 - 9
h(1) =(1 - 1)^2 - 9
Evaluate
h(1) = -9
Hence, the vertex of the function is (1, -9)
