What is the surface area of the triangles prism?? 13 points please give the right answer
MrMuchimi
First, let's calculate the triangles of the prism.

The area of a triangle is base times height, then divide by 2.

So:

(7*8)/2.

This would give us 28.

Also knowing that there are two triangles on the prism, we have to multiply 28 by 2. This would give us 56.

Now, for the rectangles, we have to find their areas.

The area of a rectangle is length times width. So this would give us:

8*16.

This equals 128.

Next, knowing that there are three rectangles, multiply 128 by three. This gives us 384.

Now, we jus have to add all the areas together:

384+56 = 440

So the prism's surface area is 440cm^2


Hope this helps. If you have any questions, please put them in the comments below.

Match the information on the left with the appropriate equation on the right.
Slav-nsk [51]

The equation of the line passing the points (-2,3),(-3,4) is y = -x + 1 or x+y = 1

<h3>Equation of a line</h3>

A line is the shortest distance between two points. The equation of a line in slope-intercept form is expressed as;

y = mx + b

m is the slope

b is the y-intercept

Given that m=1, b=-3, the required equation will be y = x - 3 or x - y = 3

For the parameter m=1, (-1,2)

y - 2 =1(x+1)

y - 2 = x+1

y =x + 3

Hence the equation of the line for the parameters m=1, (-1,2)  is y = x + 3

For the coordinates (-2,3),(-3,4)

Slope = 4-3/-3+2
Slope = -1

For the intercept;

4 =-1(-3) + b

b = 4 - 3

b = 1

Hence the equation of the line passing the points (-2,3),(-3,4) is y = -x + 1 or x+y = 1

Harlon recorded this set of data, which contains an outlier. 163, 97, 184, 199, 169, 175 What is the range of this set of data?
maks197457 [2]
Hey there!

To find the range, first put the numbers in order from smallest to largest. 
97, 163, 169, 175, 184, 199

Then take the largest number, 199, and subtract the smallest number (in this case, the outlier) which is 97.

199-97=102

Thanks for using Brainly! Hope this helps :)
