I'm solving for UW. And we're using pythagorean theorem.​

Answers

UW = 45
a squared + b squared = c squared
- 6^2 + x^2 = 9^2
- 36 + x = 81
- (subtract 36 from both sides)
- x = 45

i'm pretty sure this is right and i hope it helps you!

Answer:

6^2+x^2 = 9^2

x^2 = 9^2-6^2 = 81-36 = 45

x = √45

Answer:

x = 4, y = 116

Step-by-step explanation:

In a parallelogram, the opposite sides and opposite angles are congruent.

3x + 4 = 16 ( subtract 4 from both sides )

3x = 12 ( divide both sides by 3 )

x = 4

and

y - 60 = 56 ( add 60 to both sides )

y = 116

Answer:

132 degrees

Step-by-step explanation:

answer : 48 degrees

method

1. opposite angles are the same , so CFG os the same as GAC - these two added up are 132 + 132 = 264

2. angles add up to 360 in a quadrilateral , so the sum of the two remaining angles is 360 - 264 = 96

3. because the two remaining angles , ACF and FGA , are opposite , those are equal too. so u just half to get one of them : 96 / 2 = 48

A cubic root function has a domain of x>=7 and a range of y>=-1, what is the domain of its inverse?

Answers

Answer:

The domain of the inverse is x >= -1

Step-by-step explanation:

Functions:

Domain: Values of input(usually x).

Range: Values of output(usually y)

Inverse function:

The domain of the inverse function is the range of the original function.

The range of the inverse function is the domain of the original function.

In this question:

Original function has range y >= -1.

So the domain of the inverse is x >= -1

A company purchased​ 10,000 pairs of​ men's slacks for ​$19.36 per pair and marked them up $22.33 What was the selling price of each pair of​ slacks? Use the formula

Answers

Answer:

$41.69

Step-by-step explanation:

The computation of the selling price of the each pair of slacks is as follows:

Given that

Cost = $19.36 per pair  

Markup = $22.33

As we know that  

Markup = Sell Price - Cost

So,  

Sell Price = Cost + Markup

= $19.36 + $22.33

= $41.69

Hence, the selling price is $41.69

the screen size of a television is determined by the length of the diagonal of the rectangular screen. Traditional TVs come in a 4:3 format, meaning the ratio of the length to width of screen is 4 to 3. what is the area of a 27-inch traditional tv screen? what is the area of a 27 inch LCD tv who's screen is in a 16:9 format? which screen is larger​

Answers

Answer:

Area of 27" 4:3 screen = 349.92 square inches

Area of 27" 16:9 screen ≅ 311.5 square inches

Traditional 4:3 screen is larger

Step-by-step explanation:

The Traditional TVs is  larger than  LCD tv screen

What is diagonal of rectangle?

The diagonal of a rectangle is a line segment that joins any two of its non-adjacent vertices.

The length of diagonals of a rectangle can be calculated as:

Diagonal of rectangle = [tex]\sqrt{Length^{2} + Breath^{2} }[/tex]

According to the question

The screen size of a television is determined by the length of the diagonal of the rectangular screen.

Traditional TVs

Ratio of the length to width =  4:3

Let a be the constant for both length and width

therefore

Length of Traditional TVs = 4a

Width of Traditional TVs = 3a

The area of a 27-inch traditional tv screen

i.e

Diagonal of Traditional TVs =  27

Now applying formula of diagonal of rectangle

Diagonal of rectangle = [tex]\sqrt{Length^{2} + Breath^{2} }[/tex]

substituting the values

27 = [tex]\sqrt{(4a)^{2} + (3a)^{2} }[/tex]

27 = [tex]\sqrt{16a^{2} + 9a^{2} }[/tex]

27 = [tex]\sqrt{25a^{2} }[/tex]

27 = ± 5a

a cannot be -ve

a = 5.4

now,

Length of Traditional TVs = 4* 5.4 = 21.6 inches

Width of Traditional TVs = 3 * 5.4 = 16.2 inches

Area of Traditional TVs = Length * width

                                       = 21.6 * 16.2

                                       = 349.92 [tex]inches^{2}[/tex]

LCD TVs

Ratio of the length to width =  16:9

Let a be the constant for both length and width

therefore

Length of LCD TVs = 16a

Width of LCD TVs = 9a

The area of a 27-inch LCD TVs screen

i.e

Diagonal of LCD TVs=  27

Now applying formula of diagonal of rectangle

Diagonal of rectangle = [tex]\sqrt{Length^{2} + Breath^{2} }[/tex]

substituting the values

27 = [tex]\sqrt{(16a)^{2} + (9a)^{2} }[/tex]

27 = [tex]\sqrt{256a^{2} + 81a^{2} }[/tex]

27 = [tex]\sqrt{337a^{2} }[/tex]

27 = ± 18.357a

a cannot be -ve

a = 1.47

now,

Length of LCD TVs = 16*1.47 = 23.53

Width of LCD TVs = 9*1.47 = 13.23

Area of Traditional TVs = Length * width

                                       = 21.6 * 16.2

                                       = 311.30 [tex]inches^{2}[/tex]

Hence, the Traditional TVs is  larger than  LCD tv screen .

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $9 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has a $16 monthly fee and charges an additional $0.09 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal

Answers

Answer:

the number of minutes of call when the two cost plans would be equivalent to each other is 175 minutes

Step-by-step explanation:

The computation of the number of minutes of call when the two cost plans would be equivalent to each other is shown below:

Let us assume the number of minutes be x

Now the equation is

$9 + 0.13x = $16 + $0.09x

0.13x - 0.09x = $16 - $9

0.04x = $7

x = $7 ÷ 0.04

= 175 minutes

Hence, the number of minutes of call when the two cost plans would be equivalent to each other is 175 minutes
