Hello!
The answer is: 17 ft.
Explanation:
To find this out, just divide the perimeter, and the amount of sides in a triangle, which is 3. This will only work with equilateral triangles because an equilateral triangle has all three sides the same length. Anyway, divide 51 and 3. (51 / 3 = 17) Just to make sure, you can add three 17's together, 17 + 17 + 17 = 51, the perimeter.
I hope this helped! ~Q
Answer:
3 cups of cream
2 cups of chocolate
Step-by-step explanation:
9/3 = 3
1 x 3 = 3
2 x 3 = 6
6+3 = 9
Divide the range range between 10 fo find the appropriate scale.
[9618115 - 1013020]/10 = 8605095/10 = 860509.5
Then use scale 1: 1000000. So your marks will be
1 = 1000000
2 = 2000000
3 = 3000000
... 10 = 10000000
