Answer:
27mi
Step-by-step explanation:
Since the sailing course is equilateral in shape, then all their sides are equal.
Get one of the sides using Pythagoras theorem as shown;
Let one of the side be x
Two base will be x/2
According to the theorem;
x² = 9² +(x/2)²
x² = 81 + x²/4
x²-x²/4 = 81
3x²/4 = 81
3x² = 324
x² = 324/4
x² = 81
x = 9
Perimeter of the triangle = 3x
Perimeter of the triangle = 3(9)
Perimeter of the triangle = 27mi
Answer:
x=8
Step-by-step explanation:
15/12 = 1.25
1.25x = 10
x = 8
Literally the first thing i saw was Xbox. lol :)
Step-by-step explanation:
the volume of this object is the sum of the volume of the 2 blocks.
the large block is a cube of 4×4×4 = 64 ft³
the small block is 1×1×2 = 2 ft³
so, in total, he can fit 64+2 = 66 ft³ of plaster into the mold.

Answer:
f(x) = x^2 + 2x - 3 and g(x) = x^2 - 9
(f/g)(x) = (x^2+ 2x -3) / (x^2 - 9)
(f/g)(x) = (x +3 )(x - 1) / (x + 3)(x - 3)
(f/g)(x) = (x - 1) / (x - 3)
So
(f/g)(4) = (4 - 1)/(4 -3)
(f/g)(4) =3/1
(f/g)(4) = 3
(f+g)(x) = x^2+ 2x - 3 + x^2 - 9
(f+g)(x) = 2x^2 + 2x - 12
(f+g)(x) = 2(4)^2 + 2(4) - 12
(f+g)(4) = 32 + 8 - 12
(f+g)(4) = 28
