The dimensions of a triangular prism are shown.
Serhud [2]

9514 1404 393

Answer:

  B.  32 square inches

Step-by-step explanation:

Each of the two triangular faces has an area of ...

  A = (1/2)bh = (1//2)(6 in)(4 in) = 12 in²

The lateral surface area is the product of the prism height (0.5 in) and the perimeter of the base.

  LA = (0.5 in)(5 in +5 in + 6 in) = 8 in²

So, the total area is the area of the two base and the lateral area:

  SA = 2A +LA

  SA = 2(12 in²) +8 in² = 32 in²

The surface area of the prism is 32 square inches.

Nikitich [7]

Answer:

a) To earn C he needs at least 68 and less than 98

b) No, he couldn't make it.

Step-by-step explanation:

I. His avg value is (382 + x)/6

 I pick a random number and that gave

 (68 => to reach 75) and (98 => to reach 80)  

So that makes he needs at least 68 and less than 98

II. The reason why he cannot make it is

 if 100 is 100%

      =   (100 + 382)/6

      = 80.33 That's impossible to reach 90

Hope that help :)

(2.5 • 10^4) - (1.5 • 10^3)<br><br> Evaluate please, can you show the steps
Usimov [2.4K]


According to PEMDAS, you would look in the parenthesis first. In the first set of parenthesis we have an exponent. 10x10x10x10 is 10,000. Then we multiply this by 2.5. We now have 25,000. We put this to the side..


Next, we do the same thing on the other side -- 10x10x10 is 1,000 and then you multiply that answer by 1.5 and we have 1,500. Now we can subtract. 25,000 - 1500 = 23,500 :)
