Answer:
5/8
Step-by-step explanation:
1/4=2/8
7/8-2/8=5/8
The volume of a triangular prism is V = 1/2 x a x c x h where a is height of the triangle, c is the base of the triangle and h is the height of the prism.
120 = 1/2 x a x c x h; we write a from the previous equation in terms of c and h thus,
a = 240 / ( c x h)
If the dimensions where halved then a = a/2 ; c = c/2 ; h=h/2
We use the volume formula again and substitute the given values to find the new volume,
V = 1/2 x a/2 x c/2 x h/2
Substitute the previously determined a term,
V = 1/2 x (240/2ch) x c/2 x h/2
We cancel and evaluate the constants therefore the new volume is,
V= 15 cm^3
14 because a negative minus a negative is a positive; you add a line and change the sign
Answer:
Multiply by every term in the second expression:
Multiply by every term in the second expression.
Multiply 1 by every term in the second expression.
Now we take those nine terms (everything on the right side of those above equations) and add 'em all up
The parameters for computing the area of triangle is first listed out and the expression for the area of triangle was used to find the algebraic method
<h3>Area of Triangle</h3>
Parameters for find the area of triangle are
Let the base be x, and let the height be y
We know that the expression for the area of triangle is given as
Area = 1/2 (Bass* Height)
Substituting our parameters we have
Area = 1/2*x*y
