Answer:
Length is 90yards and width is 60yards
Step-by-step explanation:
Perimeter= 2( length+width)
let the width be x
then the length will be 30 + x
300 = 2(30+x+x)
150 = 30 + 2x
120= 2x
x = 120/2
x = 60 yards
length= 30+x
= 30 + 60
= 90yards
Answer:
84. What you did is right.
Step-by-step explanation:
A parallellogram's area is b x h. So the equation is 7 x 12=84.
Points of inflections are zeroes of the second derivative. We have:

So, the second derivative equals zero if and only if

So, this is the only point of inflection of this function.

Answer y= 16/99
Explanation:
the initial statement is
y ∝ 1/x
To convert to an equation multiply by k the constant of variation
⇒ y = k × 1/x = k/x
To find k use the given condition y = 15 when x = 5
y = k/ x
⇒ k = y*x = 8 * 2 =16
equation is

y = 16/ x
when
x = 99
then
y = 16/99
Y = 16/99
