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
The answer is A. The only way you can get the angle correct is by putting the compass in the center of the circle.
Hello from MrBillDoesMath!
Answer:
9/2 > 3/2 (slope of <u>greater than.</u>..)
Discussion:
This seems like an odd question. We can say that
9/2 > 3/2
so the slope of the line with m = 9/2 is greater than (in fact, 3 times greater than) the slope of the line with slope m = 3/2
Thank you,
MrB
Answer:
I'm not sure but I believe it is "Three plus one-half times x."
The answer is... x=4
4(4) + 7(5) = 51
Hope ive helped!
