Answer: We have to find the radio stations in 2015, which is 13.8% more than the radio stations in 2005 which were 744:

sin C = 3/5

Given:

CB = 32

AC = 40

AB = 24

To find:

sin C

To determine sinC, we will apply the sine ratio:

The simplification of the expression will be; 15t³  + 9t² + 14y

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions. To derive equivalent expressions of some expressions, we can either make them look more complex or simple.

Given that the expression as 8t³ + 8y + 7t³ + 6y + 9t²

Now combining like terms;

8t³  + 7t³ + 9t² + 8y + 6y

Simplify;

15t³  + 9t² + 14y

It cannot be solved further because of unlike terms in the expression.

Therefore, the simplification of the expression will be; 15t³  + 9t² + 14y

Given angles are corresponding angles, they are congruent (have the same measure):

Use the equation above to solve x;

You use the value of x=30 to find the measure of corresponding angles:

A dime is 10% of a dollar = 10/100 x 100 cent = 10 cents

A quater is 25% of a dollar = 25/100 x 100 cent = 25 cents

Since Karen has 5 more quaters than dimes

let quaters = q

let dimes = d

Then Karen has 5q : d = $ 3.70

$ 3.70 = 3.70 x 100 cents = 370 cents

Then

In 1 month decreases (500/100)• 18 = 90

Population = 500-90= 410

No find (410/100)•18 = 73.8

410-73.8= 336.2

The IQR of the given series 2.9, 5.7, 10.0, 13.2, 21.1 is 15.4

In the given question, a five number summary is given as follows

2.9, 5.7, 10.0, 13.2, 21.1

We need to find the IQR

So, first we'll find the median of the given series

The middle value in a sorted, ascending or descending list of numbers is known as the median, and it has the potential to describe a data collection more accurately than the average does.

So, the given series is already in ascending order. And the middle value is 10.0. So the median is 10.0

Now to find the IQR the given formula will be used,

IQR = Q3 - Q1

Where Q3 is the last term in lower series and Q1 is the last term in upper series

Lower series - 2.9, 5.7

Upper series - 3.2, 21.1

Q3 = 5.7 , Q1 = 21.1

IQR = Q3 - Q1 = 21.1 - 5.7 = 15.4 ( IQR is always positive)

Hence, the IQR of the given series 2.9, 5.7, 10.0, 13.2, 21.1 is 15.4

A relationship is called a proportional relationship if it has two variables that are realated by the same ration. In this case there will be a proportionality constant.

In this table:

Let Height be represented as H

Let Time be represented as T

For the relationship to be a proportional relationship, it must obey the relation:

When T = 3, H = 15

Using H = kT

15 = 3k

k = 15 / 3

k = 5

When T = 6, H = 30

H = kT

30 = 6k

k = 30 / 6

k = 5

When T = 12, H = 45

H = kT

45 = 12k

k = 45 / 12

k = 3.75

Since the constant of proportionality is the the same for the three cases in the table, the scenario is not a proportional relationship

The completed worksheet is the following:

This worksheet involves three measures of central tendency: Mean, Median, Mode and Range

Mean: To get the mean of a dataset, add up all the data and divide by the number of datum (or inputs)

Median: To get the median of a dataset, sort the data in ascending order, and choose the central datum.

For example, if you have a dataset with 7 inputs, sort it in ascending order and select the 4th datum, as there would be 3 values above and 3 below (Hence it being the central datum).

Mode: The mode is the most repeated value of a dataset.

Range: The range is the difference between the biggest and smallest values of a dataset.

We have to first determine the area of the square. The area of a square can be represented as follows

The number of each square feet each person will requre can be calculated as follows

We will determine the angle as follows:

We know that the whole circle contains 360°, so we determine the angle of 0.35 as follows:

So, the measure of the central angle for sector C is 126°.

The breadth of the room = 6 cm

Since the length of the room is twice its breadth

Then

Length of the room = 2 times 6cm = 12cm

The height of the room = 4cm

Since the shape of the room is a cuboid

The surface area of a cuboid is given as

Substitute l = 12, w = 6 and h = 4 into the formula

This gives

Simplify the expression

Therefore, the total surface area of the room is

Original Car price = $20,000

Price increase after 5 years = 25%

To calculate the price after 5 years, first multiply the original price (20,000) by the percentage increase in decimal form ( divided by 100) to obtain the increase amount:

20,000 x (25/100) = 20,000 x 0.25 = $5000

Finally, add the increase amount to the original price:

20,000+5,000 = $25,000

We have the next inequality

where x is the rent of each person

The maximum rent each will pay is $500

a) To calculate the minimum payment of the balance, you calculate the 2% of $4273.56. You proceed as follow:

(2/100)(4273.56) = 85.47

Hence, the mimum payment of the balance is $85.47

b) You calculate the amount of interest charged this month as follow:

convert the annual percentage rate to decimal form:

21.1/100 = 0.211

divide the previous result by 12 to get the monthly interest rate:

0.2111/12 = 0.0175

multiply the previoues result by the balance:

0.0175 x 4273.56 = 75.143 ≈ 75.14

convert the monthly rate to a percentage:

0.0175 x 100 = 1.75%

Hence, the amount of interest was $75.14, which corresponds to a 1.75%
