Answer:
3 triangles
Step-by-step explanation:
Perimeter of triangle = a + b + c
Given that :
P = 12
and a, b, c are natural numbers
Let :
Side A = a
Side B = b
Side C = 12 - (a + b)
Side A + side B > side C - - - (condition 1)
a + b > 12 - (a + b)
a + b > 12 - a - b
a + a + b + b > 12
2a + 2b > 12
2(a + b) > 12
a + b > 6
Side A - side B < side C
a - b < 12 - (a + b)
a - b + a + b < 12
2a < 12
a < 6
b < 6 (arbitrary point)
Going by the Constraint above :
The only three possibilities are :
(2, 5, 5)
(3, 4, 5)
(4, 4, 4)
Total number of triangle = 3
Equilateral triangle (all 3 sides equal) = (4, 4, 4) = 1
Isosceles triangle (only 2 sides equal) = (2, 5, 5) = 1
Leslie did. If you multiply 4/5 by two, you get 8/10. 8/10 is greater than 7/10.
H= ut -16 t^2
h = 144(2) - 16 (4)
= 288 - 64 = 224
Answer:
Frank drove 176 miles.
Step-by-step explanation:
Subtract the base fee from the total payment
152.75 - 18.99 = 133.76
divide the remaining amount(price for miles driven) by the cost for each mile
133.76 / .76 = 176
176 miles.
