Answer 1

Answer:

Explained Below

Step-by-step explanation:

You'll want to start off by knowing the formulas for the area and perimeter of triangles:

Area Formula - A= 1/2 bh (1/2 x base x height)

Perimeter Formula - P = a + b + c (sides added together)

So, we will plug in the numbers.

Triangle 1: A = 1/2 bh So, A = 1/2 8 x 10, which means half of 8 or 10 multiplied by the number that you did not half. (For instance: If you half 8, that means you multiply 4 and 10.) Now, you should have A = 40 either way (4 x 10 = 40 and 8 x 5 = 40).

P = a + b + c. So, you will add 8, 6, and 10. This is 14.

Triangle 2: A = 1/2 bh. But, this triangle requires you to cut in half. Doing this, that cuts your base as well. It will no longer be 30, by 15. For the left side of triangle 2, it will be A = 1/2 15 x 12, which you half either 15 or 12, where 12 is easier. Now it should be A = 15 x 6, which is 90. The right side of the triangle will be A = 1/2 15 (12) as well, which is also 90. In the end, you will add it together, which is 180.

P = a + b + c. So, you will add 15, 23, and 12 first. Then, add 15, 20, and 12. You should have 50 and 47, which you will add that together as well.

Triangle 3: I will keep working on this one, as I am a little unsure :/

Triangle 4: You will do the same steps for this triangle like you did on #2. Though the numbers you plug on are different. A = 1/2 bh - A = 1/2 10 x 14. (This is for the left side) You will have to half either the base or the height's number. So, it will be A= 5 x 14 or A=10 x 7. Then, you will multiply and find your answer (70). (This is for the right side) A = 1/2 10 x 14. Due to the numbers being the same, it can be shown that the area will also be 70. You then add 70 and 70 together.

P = a + b + c. You will add 10, 14, and 15 for the left side and 10, 14, and 17 for the right side. Once you add them separately, add the answers together (10+14+15 =39 and 10+14+17 = 41. 39 + 41 = 80.

Triangle 5: A=1/2 bh. A = 1/2 12 x 16. You will half either 12 or 16 (It does not matter). Then you should have A = 6 x 16 or A = 12 x 8. Either way, your answer is 96.

P = a + b + c. You will add 12, 16, and 18. This results in 46.

Hope this helps! I will continue to figure out Triangle 3

The x-intercept is the point on the x-axis where the line crosses it. The y-coordinate of the line's x-intercept is always zero. The x-coordinate of the x-intercept is the number where it crosses the x-axis. A line with an x-intercept of (5,0) crosses the x-axis at the number 5. A line with an x-intercept of (-5,0) crosses the x-axis at -5. Which of these coordinates could be a line’s x-intercept?

Answers

Answer:

D. (-7,0)

Step-by-step explanation:

If The two intercets are (5,0) and (-5,0) then (-7,0) will be an x-intercept.

Answer:

d.(-7,0)

Step-by-step explanation:

'd' is the correct answer because just as how the y-intercept has to look something like this: (0,5) as in the given 'x' point is 0 the x-intercept  has to look the exact same as well (other than the fact that it's now the x-intercept instead of y.) so it would have to be that the x-axis' point can be any number that isn't 0 and the y-axis' point must always be 0.

good luck :)

the first one is 96 i think

Answer:

1. 454

2. 96

Step-by-step explanation:

1. To find The surface area, find the are of each side. The bases of the triangular prism have the same surface area,

Surface area of triangle: 1/2b*h, half of the base times the height. base = 8, height = 10, 1/2(8) * 10 = 4*10 = 40, the other side has the same area, so double it to get 80.

The surface area of one of the rectangle is 11*14, another is 12*11, and the last is 11*8, multiply all to get 154, 132, and 88, and 154 + 132 + 88 + 80 = 454

2. The two triangles is 1/2b * h, b = 6, h = 2, 1/2(6) * 2 = 3*2 = 6, double it because there is another triangle to get 12

The three rectangles are 3*7 + 3*7 + 6*7 = 21 + 21 + 42 = 84, 84 + 12 = 96

now let us solve a-d-

-4.25-(-2.75)=-1.5

-3.25-1.75=-5

-4.50-(-5.25)=0.75

**with negative numbers the 'smaller' the number is the greater it actually is ex. -2.50<-1** it works this way because the 'larger' the number gets the further away it becomes from 0 or whole numbers making it smaller than the negative numbers closer to zero such as -1**

hopefully, that makes sense

now let us see which equations fit our inequality- **we'll let the bolded ones mean that they fit the inequality**
