Answer:
V ≈ 263.9 units³
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius and h the height )
Here r = 6 and h = 7 , then
V = [tex]\frac{1}{3}[/tex] π × 6² × 7
= [tex]\frac{1}{3}[/tex]π × 36 × 7
= [tex]\frac{1}{3}[/tex]π × 252
= 84 π
≈ 263.9 units³ ( to 1 dec. place )

What is rotation?"It is a transformation in which the object is rotated about a fixed point.""An object can be turned clockwise or counterclockwise on the coordinate plane"For given question,
We have been given a point P = (2, -1)
We know that if point (x, y) is rotated 90 degrees counterclockwise about the origin then the coordinates of image is (-y, x)
So, when point P is rotated 90 degrees counterclockwise about the origin then the coordinates of the image would be (-(-1), 2) = (1, 2)
Therefore, the image of point P is (1, 2)

Answer: 6 possible outcomes
Step-by-step explanation:

6 outcomes
The total number of outcomes is given by the equation A = 6 outcomes
What is union and intersection of sets?The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B
The union of two sets is a new set that contains all of the elements that are in at least one of the two sets
The intersection of two sets is a new set that contains all of the elements that are in both sets
Given data ,
Let the number of outcomes be represented as set A
Now , the shirts be represented as set 1
The value of set 1 = { blue shirt , black shirt , white shirt }
The number of elements in set 1 = 3
The pair of pants be represented as set 2
The value of set 2 = { blue pair , black pair }
The number of elements in set 2 = 2
Now , the total number of possible outcomes A = number of elements in set 1 x number of elements in set 2
Substituting the values in the equation , we get
The total number of possible outcomes A = 3 x 2
The total number of possible outcomes A = 6 outcomes
Therefore , the value of A is 6 outcomes
Hence , the number of outcomes is 6

What conclusion can you draw about angles of elevation for parasailing boats traveling at the same speed?
Answers
Question:
A boat is travelling at 30 mph has a 400 ft. tow line results in the height of the rider in the parasail above the water level of 300 ft.
a) Draw a labelled diagram of the situation
b) Determine the angle of elevation of the parasail rider
c) Parasailing boats traveling at the same speed will have the same angle of elevation
Answer:
a) Please find the attached drawing of the parasail boat created with MS Visio
b) The angle of elevation of the parasail rider from the boat is approximately 48.6°
Step-by-step explanation:
a) Please find the labelled diagram of the parasailing boat created with MS Visio
b) sing trigonometric ratios, we have;
[tex]sin(\theta) = \dfrac{Opposite \ leg \ length}{Hypotenuse \ length}[/tex]
The opposite leg = The height of the parasail rider above water = 300 ft.
The hypotenuse = the length of the tow line = 400 ft.
θ = The angle of elevation of the parasail rider
[tex]\therefore sin(\theta) = \dfrac{300 \, ft.}{400 \, ft.} = 0.75[/tex]
θ = Arctan(0.75) ≈ 48.6°
The angle of elevation above the horizontal of the parasail rider from the boat, θ ≈ 48.6°
c) From the construction of the drawing and the derivation of the angle of elevation given only the length of the tow line and the height given to the parasail rider by the speed of the both,
Parasailing boats traveling at the same speed, having the same length of tow line, will have the same angle of elevation, provided other factors that have an effect on the angle of elevation are the same

One year, the population of a city was 397,000. Several years later it was 412,880.
Find the percent increase.
Answers
The percentage increase from the initial population of 397,000 to 412,880 is 4%
How to determine the percentage increase?From the question, we have the following numbers:
397,000 and 412,880.
The numbers are increments from 397,000 to 412,880.
The percentage increase is calculated as:
%Percentage = (Old number - New number)/Old Number
Substitute the numbers in the above equation
%Percentage = (412880 - 397000)/397000
Evaluate the difference
%Percentage = 15880/397000
Evaluate the quotient
%Percentage = 0.04
Express 0.04 as percentage
%Percentage = 4%
Hence, the percentage increase from the initial population of 397,000 to 412,880 is 4%

Students from the local high school are selling tickets to the town's annual carnival. Adult
admission is $5.00 and child admission is $2.50. Two hours after the carnival opened its first
day, 440 tickets had been sold totaling $1900. How many adults and how many children
entered the carnival during the first two hours it was open?
Answers
Answer:
320 adults and 120 children
Step-by-step explanation:
First set up two sets of equations. One will equal the total amount of money sold and the other will equal the total amount of tickets sold.
5a + 2.5c = 1900 where a is the # of adult tickets sold and c is the # of children tickets sold
a + c = 440
Now solve for either a or c in the second equation. I chose to solve for a. a=440-c
Use that to substitue into the other equation.
5 (440-c) +2.5c = 1900
2200-5c +2.5c = 1900
-5c+2.5c = -300
-2.5c=-300
c=120
Now plug 120 into the equation a+c=440 and solve for a

Give your answer rounded to 1 DP.
a

The diagram is not drawn accurately.
Answers
Answer: 23 cm
Step-by-step explanation:
Given
[tex]a=3.5\ cm\\b=9.4\ cm[/tex]
Triangle in the figure is right-angled triangle. Therefore, Pythagoras theorem can be applied. Suppose the unknow length of the triangle is x
[tex]\Rightarrow x^2=a^2+b^2\\\Rightarrow x^2=3.5^2+9.4^2\\\Rightarrow x^2=12.25+88.36\\\Rightarrow x^2=100.61\\\Rightarrow x=10.03\ cm[/tex]
The perimeter of triangle is the sum of the lengths of sides.
[tex]\text{Perimeter }P=3.5+9.4+10.03\\\Rightarrow P=22.93\ cm\approx 23\ cm[/tex]
