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
Solve.

The sum of two numbers is 65. The larger number is five more than three times the smaller number. What are the numbers? (Systems of Equations)
Answer:
x=44 and y=21
Step-by-step explanation:
The large one is x
The small one is y
According to given conditions,
x+y=65[Sum of two number is 65]—Equation(1)
x-23=y [Smaller number is less than 23 than larger]——Equation (2)
From equation (2) we can write,
x-y=23——-Equation(3)
Now adding equation (1) and (3) we get,
x+y+x-y=65+23
=>2x=88
=>2x/2=88/2 [Both sides are divided by 2]
=>x=44
Now putting the values in equation (2) we get,
44–23=y
=>y=21
Large, x=44 and Small, y=21

The lifespan of a hamster is 4 years less than that of a rabbit. The lifespan of a raccoon is 2 times that of the hamster. If the total lifespan of the animals is 24 years, calculate the longevity for the rabbit.
Answer:
9 years
Step-by-step explanation:
Let
Lifespan of rabbits = x
Lifespan of hamster = x - 4
Lifespan of raccoon = 2(x - 4)
Total lifespan of animals = 24
Total = rabbits + hamster + raccoon
24 = x + (x - 4) + 2(x - 4)
24 = x + x - 4 + 2x - 8
24 = 4x - 12
24 + 12 = 4x
36 = 4x
x = 36/4
x = 9 years
longevity for the rabbit = 9 years
Lifespan of rabbits = x = 9
Lifespan of hamster = x - 4
= 9 - 4
= 5
Lifespan of raccoon = 2(x - 4)
= 2(9 - 4)
= 2(5)
= 10
Total lifespan of animals = 24

I need help with geometry
Answer:
146
Step-by-step explanation:
angle AB is an inscribed angle and arc AB is it's intercepted arc
An inscribed angle is equal to half the measure of its intercepted arc
Which means that an intercepted arc is equal to two times the measure of its corresponding inscribed angle
Thus, arc ab = 2(73)
2 * 73 = 146
hence, arc AB = 146
Answer:
mAB = 146°
Step-by-step explanation:
We can notice that the angle given is an inscribed angle and an inscribed angle is 1/2 the arc it intercepts. We can set up an equation to model the situation:
73° = 1/2(mAB)
mAB = 146°
The half-life of a radioactive kind of radium is 11 days. If you start with 72 grams of it, how
much will be left after 22 days?
[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Radioactive decay.
N(t) = 72(1/2)^22/11
==> N(t) = 72 (1/2)^2
==> N(t) = 72/4
==> N(t) = 18 grams.
So the remaining would be 18 grams.
