Answer 1

Answer:

Step-by-step explanation:

a/c =b/d where a=27 c=30 b=x d=18

27/30 = x/18

27*18/30=x

16.2 = x

a/c =b/d where a=2x-5 c=x+11 b=16 d=14

2x-5 / x + 11 = 16 / 14

14(2x-5) = 16(x+11)

28x - 70 = 16x + 176

12x = 246

x = 20.5

6+15 / 7+x = 7 /6

6(6+15) = 7(7+x)

6*21 = 49 +7x

126 = 49 +7x

77 = 7x

11 = x

3*[(x-6)+3]=[tex]6^{2}[/tex]

3(x-3) = 36

3x-9 = 36

3x = 45

x = 15

What is a trapezoid?

The Trapezoid is a 4 sided polygon. Two sides of the shape are parallel to each other and they are termed as the bases of the trapezoid. The non-parallel sides are known as the legs or lateral sides of a trapezoid.

There are three types of trapezoids , and those are given below:

a) Isosceles Trapezoid

b) Scalene Trapezoid

c) Right Trapezoid

The area of the Trapezoid is given by

Area of Trapezoid = ( ( a + b ) h ) / 2

where , a = shorter base of trapezium

b = longer base of trapezium

h = height of trapezium

Given data ,

Let the area of the figure be S = 2 ( area of trapezium ) + 2 ( area of opposite rectangles ) + ( area of smaller rectangle ) + area of larger rectangle

On simplifying , we get

2 ( area of trapezium ) = ( a + b ) x h

2 ( area of trapezium ) = ( 19 + 5 ) x 12.1

2 ( area of trapezium ) = 290.4 feet²

Now , 2 ( area of opposite rectangles ) = 2 ( 14 x 8 )

2 ( area of opposite rectangles ) = 224 feet²

Area of smaller rectangle = 5 x 8 = 40 feet²

Area of larger rectangle = 8 x 19 = 152 feet²

Therefore , S = 290.4 feet² + 224 feet² + 40 feet² + 152 feet²

S = 706.4 feet²

Hence , the area of the figure is S = 706.4 feet²

A package is shaped like a right rectangular prism. Use the dimensions shown to find the surface area of this package.

A)6 square feet
B)12 square feet
C)20 square feet
D)22 square feet

Answers

Answer:

The surface area is 22 square feet

Step-by-step explanation:

For a right rectangular prism, we have the formula for the area as;

A = 2(lb + lh + bh)

Accordingly, we have l as the length, b as the breadth and h as the height

Using the given dimensions, we have

A = 2(3(1) + 3(2) + 1(2))

A = 2(3 + 6 + 2)

A = 2(11) = 22 square feet

A company's flexible budget for 12,500 units of production showed sales, $50,000; variable costs, $20,000; and fixed costs, $15,000. The operating income expected if the company produces and sells 15,000 units is:

Answers

Answer: $21000

Step-by-step explanation:

First, we calculate the contribution margin which will be:

=Sales - Variable cost

= $50,000 - $20,000

= $30,000

Therefore, the contribution margin per unit will then be:

= $30,000 / 12500

= $2.4 per unit

The operating income will be the difference between the total contribution margin and the fixed cost. This will be:

The total Contribution margin will be:

= $2.4 × 15000

= $36000

Fixed costs = $15000

Operating income = $36000 - $15000

= $21,000

Answers

Answer:

Step-by-step explanation:

length of an arc = theta/360 * 2πr

Given

m<HJK = 50

HJ = 16units

Required

length of arc HK

arc HK = 50/360 * 2(3.14)(16)

arc HK = 5/36 * 100.48

arc HK = 502.4/36

arcHK = 13.96

Justin has a savings account.
• He started with $70 in his account.
• He deposits $15 into the account each week.
What is the total amount Justin will have in his account after 10 weeks?

Answers

Answer:

220

Step-by-step explanation:

Multiply 15 times 10 =150

150+70=220

Hope this helps :)

Answer: 220 dollars

==========================================================

Explanation:

After 10 weeks, he'll deposit a total of 15*10 = 150 dollars on top of the $70 already in the account. This means the grand total is 150+70 = 220 dollars

If you need to use algebra, then an algebraic expression you can use is 70+15x where x is the number of weeks. Replace x with 10 and you'll end up with 70+15*10 = 70+150 = 220. It's effectively the same idea and steps as the previous paragraph, but now we're involving a variable.

They were called "Choose Your Own Adventure" novels. The idea was pretty simple. You'd start reading and then a few pages into the book, there would be a plot development that required a choice. The book might describe that you've entered a spooky house and the door has locked behind you. It would then ask you if you want to try to exit by going through the kitchen or exploring upstairs. If you chose to go into the kitchen, you'd turn to page 200, if you chose to go upstairs, you'd turn to page 43. This would repeat maybe five or six times though the book. You could re-read it a few times and try different outcomes.In this lab you are going to create a choose your own adventure application using navigation controllers. The introduction screen to your application will contain a few lines of text to set up a story and then leave the user with a choice. Below the text, you will present two buttons that correspond to the different choices.For example, you might see the following text on the main screen:You are walking down the street when a tiger runs up and takes your lunch and then runs away...Do you want to chase the tiger or run away?ChaseRun AwayThe user must then tap one of the buttons. This will move the user to a new screen with a few more lines of the story and another choice and two more buttons. You will create three (3) turning points in your story. This means that your story will have eight (8) different possible outcomes and a total of 15 screens.RequirementsThe story must ask three (3) questions, no matter how the user answers the previous question.
