The perimeter is the sum of all side lengths of a given shape, and can be computed by adding up all of the side lengths.
So in this case, it would be 15 x 2 + 13 x 2 the sum of them would be equal to the perimeter of the object, I believe.
Answer:
Part A
5yr old boy.
Y=-(1/8)x+113/8 x=5
Y=-5/8+113/8=(113-5)/8=108/8
Y=13.5 hrs
Yes the estimated value of sleep by this function is reasonable as it is close to childhood more sleep is likely.
Part B
20yr old boy.
Y=-(1/8)x+113/8 x=20
Y=-20/8+113/8=(113-20)/8=93/8
Y=11.63 hrs
No the estimated value of sleep by this function is not reasonable as the normal sleep of 7-8 hrs is enough for adults.
Step-by-step explanation:
First you subtract 3 from both sides. 3-3 and 7-3, that cancels out 3 which leaves you with r>4.
The 60$ system had a greater percentage decrease because it was a lower number to begin with. Taking the same portion out of two different numbers will always be a greater decrease for the lower number.
C rational numbers
natural numbers are numbers like
1, 2, 3, 4 etc
whole numbers are numbers without a fraction or decimals (natural)
irrational is just bunch of random numbers
