Find the total surface area of this triangular prism
FinnZ [79.3K]

Answer:

976 cm^2.

Step-by-step explanation:

The surface area = 2 * area of the triangular side + 2 * area of the rectangular sides + area of the rectangular base.

= 2 + 1/2 * 24 * 14 + 2 * 25 * 10 + 14*10

= 336 + 500 + 140

= 976 cm^2.

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

2x + y = 3

-2x + 5y = -9

<u>Step 2: Solve for </u><em><u>y</u></em>

<em>Elimination</em>

  1. Combine equations:                    6y = -6
  2. Divide 6 on both sides:               y = -1

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Define equation:                    2x + y = 3
  2. Substitute in <em>y</em>:                       2x - 1 = 3
  3. Isolate <em>y</em> term:                        2x = 4
  4. Isolate <em>y</em>:                                 x = 2

Sarah, Amy and Liam stand on some weighing scales two at a time.
ahrayia [7]
So here is how to solve the problem.
Let us analyze it first.
S + A = 70
S + L = 80
L + A = 80
Since S + L is equal to L + A, this would mean that S = A.
So S + A = 70 So A = 70/2 = 35kg
And lastly L. L= 80 -35 = 45kgs.
Therefore, Liam's weight is 45kgs.
Hope this explanation helps.
Let me know if you need more help next time. Have a great day!
