Given that a = 3.5 cm and b = 9.4 cm, work out the perimeter of the triangle.

Give your answer rounded to 1 DP.

a

b

The diagram is not drawn accurately.

**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]

What conclusion can you draw about angles of elevation for parasailing boats traveling at the same speed?

**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

A drawer contains a blue shirt, a black shirt, and a white shirt. Another drawer contains a blue pair of pants and a black pair of pants. One shirt and one pair of pants are chosen at random.

How many different possible outcomes are there?

I will mark brainiest on whoever gets it right.

**Answer: 6 possible outcomes**

**Step-by-step explanation:**

**blue shirt - blue pants**

**blue shirt - black pants**

**black shirt - blue pants**

**black shirt - black pants**

**white shirt - blue pants**

**white shirt - black pants**

**6 outcomes**

The total **number **of outcomes is given by the **equation **A = 6 outcomes

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

One year, the population of a city was 397,000. Several years later it was 412,880.

Find the percent increase.

The **percentage increase **from the initial population of 397,000 to 412,880 is 4%

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?

**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

If P =(2,-1) , Find the image of P under the following rotation 90 degrees

( [ ? ] , [ ? ] )

Answer:(1,2)

Step-by-step explanation:

The image of point P = (2, -1) is (1, 2)

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)

A mens health magazine would like to conduct a survey using a simple random sample of 900 men who practice yoga. One of the goals of the survey is to create a confidence interval to estimate the proportion of all men practicing yoga who report low stress levels. Since the intended survey method requires face-to-face interaction, some of the magazine executives are concerned about the cost of the survey and suggest sampling a smaller group of 100 men instead of 900 men. Assuming the sample proportion doesnt change, which of the following best describes the anticipated effect on the width of the confidence interval if the magazine were to survey a random sample of 100 men who practice yoga, rather than 900 men? A) The width of the interval based on 100 men would be about nine times the width of the interval based on 900 men. B) The width of the interval based on 100 men would be about three times the width of the interval based on 900 men. C) The width of the interval based on 100 men would be about the same width as the interval based on 900 men. D) The width of the interval based on 100 men would be about one-third the width of the interval based on 900 men.
