Answer:

Surface area of the triangular prism is $1380m^2$

Step-by-step explanation:

The triangular prism have two triangular faces and three rectangular faces:

So, the Area of the Prism is :

Area of the two triangular faces+ Area of the three rectangular faces

Surface area of the triangular prism :

$2(1/2*24*10)+(19*10)+(24*19)+(26*19)\\\\ = 240+190+456+494\\\\ =1380 m^2\\$

So, the area of the triangular prism is $1380m^2$

Why is 1/6 greater than 1/8 but less than 1/3

mina [271]

I would show it in decimals. Seeing it to show how close it is to one would make it a lot easier- 1/6= .16. 1/8=.125 and 1/3=.33 So looking at the decimals you can see how one would be bigger than the other

Answer:

A: 500 square feet

Step-by-step explanation:

A: First you have to draw a grid.

You plot the points A,B, and C.

The fourth point would be -5,25 because it matches with the points.

You make a rectangle out of those points

Points AB is 2 feet. Since the interval I used was 5 I would multiply 2 by 5 to get 10.

Then I would find Points BC which is 10 feet. Again multiply it by 5 to get 50.

50 x 10 is 500.

B: Jenna has to reflect over the y-axis. This is because the y-axis is between Quadrants II and I. When reflecting over the y-axis the y-coordinate stays the same but the x-coordinate switches to it's opposite. Basically the x-coordinate is negative in Quadrant II, but in when reflecting over the y-axis the x-coordinate would change to a positive in Quadrant I. So if the point in Quadrant II looks like this: (-X,Y) then when reflecting over the y-axis to Quadrant I would look like this: (X,Y).

Maristella is constructing an isosceles triangle to use as a model in her Algebra class. The perimeter of her triangle is 24 cm.

Vlada [557]

Isolating s, the equation written in terms of s is:

$s = 12 - 0.5b$

-------------------------

The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

$b = 24 - 2s$
