The distance the 12 centimeters minute hand moves in 20 minutes obtained by converting the angular motion to translational motion is about 25.133 centimeters
What is an angular motion?Angular motion is the circular motion of an object around a point or location.
The complete 360° rotation of the minute hand = 60 minutes
Therefore;
60 minutes is equivalent to 360°
1 minute is equivalent to 360°/60 = 6°
20 minutes is equivalent to 20 × 6° = 120°
The circular path motion following an angular rotation of angle theta = Radius × Theta
Where, theta is in radians
The radius of the minute hand = 12 centimeters
360° = 2•π radians
120° = 360°/3 = (2•π/3) radians
The distance moved by the the minute hand = 12 cm × (2•π/3) radians = 8•π cm
8•π cm ≈ 25.133 cm
The distance the minute hand moves in 20 minutes is about 25.133 cm

The slope is calculated as
m = (2 - 20)/(14 - 32)
m = 1
So, the equation is
y = mx + c
Using the points, we have
1(32) + c = 20
Evaluate
c = -12
So, we have
f(x) = x - 12
Using the above function, we have the following function values
f(-10) = -10 - 12 = -22
x - 12 = -6

...............................................................................................................................................
Answer:
The correct option is B.
Step-by-step explanation:
From the given table it is notices that the value of y decreases as x increases, therefore it is an inverse variation.
The inverse variation is defined as
Where, k is constant of proportionality.
From the given table it is clear that the value of y is 6 at x=2.
The value of k is 12. So, the required model is
Therefore, the correct option is B.

Jennifer is buying party supplies. She is planning on buying twice as many balloons as noisemakers. The number of napkins Jennifer is planning on buying is one-quarter of the number of noisemakers. If Jennifer buys 65 items, how many noisemakers does Jennifer buy? Write and solve an equation using a variable for this problem. <3
(trying to finish all my hw today since I have irl school starting tomorrow, I'm going to a new school:(
NO LINKSS
Answer:
20 noisemakers; 40 balloons; 5 napkins
Step-by-step explanation:
n = noisemakers amount
b = balloons amount
k = napkins amount
n/4 = k
b = 2n
b + n + k= 65
plug first and second equation into the respected variables in the 3rd equation so:
2n + n + n/4 = 65
multiple both sides by 4 to get rid of fraction
4(2n + n + n/4) = 4*65
8n + 4n + n = 260
13n = 260
n = 20
use n = 13 to get the other variables
b = 2(20)
b = 40
(20)/4 = k
k = 5
A hexagonal prism has a base with an area of 15 square inches and the volume is 105 cubic inches.
Answer:
The height is 7 inches
Step-by-step explanation:
Given
[tex]Base\ Area = 15in^2[/tex]
[tex]Volume = 105in^3[/tex]
Required
Determine the height [missing from the question]
The volume of a hexagonal prism is:
[tex]Volume = Base\ Area * Height[/tex]
Make Height the subject
[tex]Height = \frac{Volume}{Base\ Area}[/tex]
[tex]Height = \frac{105in^3}{15in^2}[/tex]
[tex]Height = \frac{105in}{15}[/tex]

The drone in the Example hovers at 16 meters for a few minutes before being
lowered at a constant rate. It reaches the ground after 6 seconds.
a. Why can the drone's descent be modeled by a linear function?
The drone's descent can be modeled by a linear function as the rate of descent is constant.
How to define the linear function?The slope-intercept definition of a linear function is given as follows:
y = mx + b.
In which:
m is the slope, representing the rate of change.b is the intercept, representing the value of y when x = 0.For this problem, we have that the drone descended 16 meters in 6 seconds, hence the slope m is given as follows:
m = -16/6 = 2.67 m/s.
As the slope is constant, a linear function can model the situation.

Two similar cylinders have heights of 3 cm and 6 cm respectively. If the volume of the smaller cylinder is 30 cm3, find the volume of the larger cylinder.Required to answer. Single line text.
Answer:
Volume of big cylinder = 1,438.76 cm (Approx.)
Step-by-step explanation:
Given:
Height of smaller cylinder = 3 cm
Height of big cylinder = 6 cm
Volume of smaller cylinder = 30 cm³
Find:
Volume of big cylinder
Computation:
Volume of smaller cylinder = πr²h
(22/7)(r²)(3) = 30
Radius of small cylinder = 1.783 cm (Approx.)
So,
Radius of big cylinder = 1.783 x 2 = 3.566 cm (Approx.)
Volume of big cylinder = πr²h
Volume of big cylinder = (22/7)(3.566)²(6)
Volume of big cylinder = 1,438.76 cm (Approx.)

QUESTION 8 of 10: Juanita, the stadium manager, spends $10,000 on a broadcast TV ad, $15,000 on a cable TV ad, and $4,000 on a radio ad
What percentage of radio advertising did she do? (Round to the nearest percent.)
Answer: 13.79%
Step-by-step explanation:
Amount spent on broadcast TV advertisement = $10000
Amount spent on cable TV advertisement = $15000
Amount spent on radio advertisement = $4000
Total amount spent advertisement = $10000 + $15000 + $4000 = $29000
The Percentage of radio advertisement done will be:
= (Amount spent on radio advertisement / Total amount spent advertisement ) × 100
= (4000 / 29000) × 100
= 13.79%

Answer:
Red
Step-by-step explanation:
Let x = number of laps and Let y = time taken to complete laps
She is able to run one lap in 7 minutes
Given this information we want to create an equation
the equation would be
7x = y
Now that we have created an equation we want to find how many laps she can run in 56 minutes.
The time is represented by 7 so we plug in 56 into y
so now we have
7x = 56
Finally we solve for x
*divide each side by 7*
56/7 = 8
7x / 7 = x
we're left with x = 8 meaning that she can run 8 laps in 56 minutes
In conclusion the answer is the Red one
Find the values of x and y. Write your answers in simplest form.
Step-by-step explanation:
You have this rule, if there is < 30° then value of y is
y=12✓3:2
y=6√3
And Pitagora's theorem:
c²=a²+b²
In this case:
(12√3)²=y²+x²
Then x is:
x²= (12√3)²-y²
x²= (12√3)²-(6√3)²
x²=432- 108
x²= 324
x=✓324
x=18cm
