Answer:

1152 ft^2

Step-by-step explanation:

There are 7 faces on this solid.

I will label the faces and will calculate each area with an explanation.

Faces 1 and 2:

The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.

Each face is a rectangle and a triangle.

area = area of rectangle + area of triangle

area = LW + bh/2

area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2

This is area of of face 1, the front face. Face 2, the rear face has the same area.

A1 = 126 ft^2

A2 = 126 ft^2

Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft

area = LW

area = 9 ft * 20 ft = 180 ft^2

A3 = 180 ft^2

Faces 4 and 5:

The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.

area = LW

area = 12 ft * 20 ft = 240 ft^2

A4 = 240 ft^2

A5 = 240 ft^2

Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.

area = LW

area = 6 ft * 20 ft = 120 ft^2

We need 2 of these area.

A6 = 120 ft^2

A7 = 120 ft^2

total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7

total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 + 120 ft^2 + 120 ft^2

total surface area = 1152 ft^2

The answer is: 1152ft^2

Use the equation: C=0.5n to determine the cost for 14 hamburgers in dollars

Answers

C=$7.00

C stands for the cost, and n would be the amount of hamburgers. Since we are looking to determine the costs of 14 hamburgers we would have to then multiply 0.5 and 14.

14 x 0.5 =7

So your answer is 7 dollars

14 times 0.5 = 7 would be correct i think.

Two linear functions are represented in different formats.

Function 2:

Graph of a line passing through the point begin ordered pair negative 2 comma 0 end ordered pair and the point begin ordered pair 0 comma 4 end ordered pair.

Which statements are true?

Select each correct answer.

Function 1 has a greater rate of change than function 2.

Function 2 has a greater rate of change than function 1.

Function 1 has a greater y-intercept than function 2.

Function 2 has a greater y-intercept than function 1.

Answers

The statements that are true are;

Function 2 has a greater rate of change than function 1.

Function 2 has a greater y-intercept than function 1.

Step-by-step explanation:

Given that function 1 has the table;

x y

0 -2

2 0

3 1

5 3

Finding the slope of the linear function gives the rate of change of the function. In this case,

m=Δy/Δx

m=3-1/5-3 = 2/2 =1

The equation of the linear function is given as;

m=Δy/Δx

y-3/x-5= 1

y-3=x-5

y=x-5+3

y=x-2

y-intercept is -2

In function 2, the line passes through points (-2,0) and (0,4)

Finding the slope of the line,

m₁=Δy/Δx

m₁=4-0/0--2

m₁= 4/2 =2

Rate of change is 2

Finding the equation of the line

y-4/x-0 = 2

y-4=2(x-0)

y-4 =2x

y=2x+4

The y-intercept is 4

The statements that are true are;

Function 2 has a greater rate of change than function 1.

Function 2 has a greater y-intercept than function 1.

Answer:

Step-by-step explanation:

Since this is a test, I'll give a hint.

This problem can be a little confusing, but thats ok! The problem is trying to make two models, (each model is a number) and asking you to find what the addition sentence is.

If that makes you confused, then that's probably the right response! The first thing you would need to know is what are they dividing the whole circles of? Thirds? Seconds? Sixths?

You would then need to know how many whole numbers are there. "Whole numbers" are basscially fully shaded circles.

The floor of the entryway to an office building will be triangular. Two angles of the triangle will measure 40°, and the side between them will have a length of 8 meters. Make a scale drawing of the entryway using a scale of 1 cm : 2 m. Explain how you made your drawing.

Answers

Answer: The drawing in the attached figure

Step-by-step explanation: we know that

An isosceles triangle, has two equal sides and two equal interior angles

In this problem, the floor of the entryway to an office building is in the shape of an isosceles triangle

step 1

Find the measure of the vertex angle

Remember that

The sum of the interior angles in any triangle must be equal to 180 degrees

Let

x ---> the measure of the vertex angle of triangle

step 2

Find the length of the congruent sides of triangle

Applying the law of sines

Let

c ----> the length of one congruent side

we have

substitute

solve for b

step 2

Make a scale drawing of the entryway

The scale drawing is 1 cm : 2 cm

That means

1 cm in the drawing represent 2 cm in the actual

1 cm in the drawing represent 0.02 m in the actual

Find the dimensions in the drawing

For a=8 m

For b=5.22 m

step 3

Draw the triangle

GUYS, PLEASE ANSWER MY QUESTION! Please it's due today, everybody else got their questions answered! Listen to me!

Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.
Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct?

Answers

Answer:

Arianna is correct

Step-by-step explanation:

She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.

arianna is the correct answer

What is the value of b. If A+B=C and A=35 and C=25
Explain how you got this answer

Answers

Answer:

[tex]B=-10[/tex]

Step-by-step explanation:

Hi!

So let's write the equation again

[tex]A+B=C[/tex]

The next step is to plug in known values:

[tex]35+B=25[/tex]

Now we solve this as a normal algebra equation:

Do same to both sides

[tex]B = 25-35[/tex]

[tex]B=-10[/tex]

I hope this helped. Let me know if you have any questions

The answer is -10. No positive number could equal 25 and if 35-25 is 10, it would only make sense to be negative. Say if you have $25 but you need 35, you’d be in debt of $10 you borrowed from someone else. Hope this makes sense, I’m not the best at explaining.

Gina visited the aquarium with some of her cousins, aunts, and uncles. The group bought 20 admission tickets for $340. Adult tickets cost $20, and children’s tickets cost $15. How many adult tickets and how many children tickets did the group buy?

Write a system of equations.

Answers

Answer:

Look at the attachment

Step-by-step explanation:

There are 12 children tickets did the group buy.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The group bought 20 admission tickets for $340.

And, Adult tickets cost $20, and children’s tickets cost $15.

Let number of children = x

And, Number of adult = y

Hence, We get;

The system of equations are,

x + y = 20

y = 20 - x .. (i)

And, 15x + 20y = 340

3x + 4y = 68 .. (ii)

Substitute the value of y from (i) in (ii);

3x + 4(20 - x) = 68

3x + 80 - 4x = 68

80 - 68 = x

x = 12

Thus, There are 12 children tickets did the group buy.
