Volume of triangular prism is area of triangle times the length
Area of triangle is:
A=1/2BH
A = 1/2 3 X 10
A = 15
Then take the area of the triangle times the length of the prism, which is 8
V = Area of triangle X length
V = 15 X 8
V = 120 yd3

15 points. What is the value of k?
Lubov Fominskaja [6]

Answer:

k = 10

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ ZYM is an exterior angle of the triangle, thus

4k + 5 + 6k + 10 = 115, that is

10k + 15 = 115 ( subtract 15 from both sides )

10k = 100 ( divide both sides by 10 )

k = 10

Consider this equation. 7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8) Mia solved the equation and determined that m=2. Is she correct?
IgorC [24]

Answer:

B) She is incorrect because when substituting 2 for m the result was a false statement.

Step-by-step explanation:

Let's solve it for ourselves and see if Mia is correct:

7.8+2(0.75m+0.4)=-6.4m+4(0.5m-0.8)

7.8+1.5m+0.8=-6.4m+2m-3.2

1.5m+8.6=-4.4m-3.2

8.6=-5.9m-3.2

11.8=-5.9m

-2=m

m=-2

Since the answer is actually m=-2, Mia's guess is incorrect because plugging in m=2 does not make both sides equal. Therefore B is the correct option.
