What is the surface area of the Triangular Prism rounded to the nearest tenth?
A)18.5
B) 36.9
C) 43.6
D) 87.2

Answers

Answer:

C. 43.6

Step-by-step explanation:

you need to take the area of each shape

lets do the skinny triangles first on the top and bottom of this shape.

so to find the formula of triangle we need to do 0.5 * 1.26 * 5.3

because the formula of a triangle is half the base times height.

so we get 0.5 * 1.26 * 5.3 = 3.339

multiply it by two and we get 6.678

now lets find the area of the huge rectangle on the back/behind of the shape

3.3*5.3 = 17.49

now lets find the area of the two smaller rectangles

3.3 * 3.6 = 11.88

2.3 * 3.3 = 7.59

now lets add

6.678 + 17.49 + 11.88 + 7.59 = 43.638

round it to 43.6

I think the answer is C. 43.6

What is the equation of the line in slope intercept form that has a slope of 1/2 and passes through (2,3)

Answers

Y=1/2x + 3

Hope this helps

Answer:

y = 1/2x + 2

*view the attached graph to double check the answer*

Step-by-step explanation:

y = mx + b

m = slope

b = y-intercept

y = mx + b

y = 1/2x + b

(2, 3) ==> substitute the numbers into the equation

y = 1/2x + b

3 = 1/2(2) + b

3 = 1 + b

-1   -1

2 = b

Our final equation: y = 1/2x + 2

Check your answer using (2, 3):

y = 1/2x + 2

3 = 1/2(2) + 2

3 = 1 + 2

3 = 3

This statement is correct

Hope this helps!

You just multiply the number out of the parentheses by each number inside.  If it has a variable, in this case "x" then you just put "x" right after the number.

Example: 2(3x)= 6x

If there is just a negative out of the parentheses then you just change the sign.

Example: -(5x-3)= -5x+3

Two times the cost of a burger and fries is $10. If the fries are $1 how much is the burger?

Answers

10 divided by 2 minus 1 equals 4

Answer:

Step-by-step explanation:

b = cost of 1 burgerf = cost of fries$1 = the cost of fries

2(b+f) = 10

2b + 2f = 10

2b + 2(1) = 10

2b + 2 = 10

2b = 8

/2     /2

b = $4 <== the cost of each burger

If she could have spoken her thoughts, it would have been to say that this was not what they had aimed at when they had set themselves years ago to work for the overthrow of the human race. These scenes of terror and slaughter were not what they had looked forward to on that night when old Major first stirred them to rebellion. If she herself had had any picture of the future, it had been of a society of animals set free from hunger and the whip, all equal, each working according to his capacity, the strong protecting the weak, as she had protected the lost brood of ducklings with her foreleg on the night of Major's speech. Insteadshe did not know whythey had come to a time when no one dared speak his mind, when fierce, growling dogs roamed everywhere, and when you had to watch your comrades torn to pieces after confessing to shocking crimes. There was no thought of rebellion or disobedience in her mind. She knew that, even as things were, they were far better off than they had been in the days of Jones, and that before all else it was needful to prevent the return of the human beings. Whatever happened she would remain faithful, work hard, carry out the orders that were given to her, and accept the leadership of Napoleon. But still, it was not for this that she and all the other animals had hoped and toiled. It was not for this that they had built the windmill and faced the bullets of Jones's gun. Such were her thoughts, though she lacked the words to express them.How does Clovers response support the authors purpose?
