question 12(multiple choice worth 1 points) (03.05 lc) what is the volume of a sphere with a radius of 6 inches? 112π cubic inches 288π cubic inches 290π cubic inches 300π cubic inches

The circumference of the given circle is: 16πcm.

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.

The unit rate in minutes per meter is 12½ min./m if it takes 15 over 2 minutes to fill an empty aquarium to a depth of 3 over 5 meters.

It takes 15/2 mins to fill an empty aquarium to a depth of 3/5 meters.

In a situationism like this we can make a equation such as

15/2 = 3/5

Lets multiply 5 in both sides

15/2 × 5= 3/5 × 5

75/2 = 3

Now lets divide both sides with 3

(75/2)/3 =3/3

25/2 = 1

Thus, the unit rate in minutes per meter is 12½ min./m if it akes 15 over 2 minutes to fill an empty aquarium to a depth of 3 over 5 meters.

Which car goes faster, a car that travels 42 miles in three hours or a car that travels 132 miles in seven hours? The solution is determined by the unit rate of each automobile. Rather than comparing the distances traveled in two or seven hours, compare how far each car drives in one hour.

A unit rate is just a ratio of two unit values, with the denominator always being one. This enables easy comparison of data values. To mention a few, common unit rates in the real world include miles per hour (MPH), price per unit, miles per gallon (MPG), revolutions per minute (RPM), and pay per year.

average inflation rate of cold drink will be 100%

Inflation is the term used to describe an increase in the price of goods and services that households buy. It is determined by how quickly these prices fluctuate. Prices frequently rise with time, but they can also fall (a situation called deflation).

You will subtract the starting price (A) from the later price (B), and divide it by the starting date (A). Then multiply the result by 100 to get the inflation rate percentage.

FORMULA FOR FINDING AVERAGE INFLATION = ((B-A)/A)*100

89 degrees

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.

This 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.

Next, subtract 91 from both sides.

To check our answer we can plug it back into the original equation.

This means that the missing angle must be 89 degrees.

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°

See attachment for the graph of the function and the features

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)

The measure of angle A in the triangle is 18°

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°

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.

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.
